Do you need professional CCTV Camera installation services in Kenya? Haven secure solutions is the company to contact. We Have hands on experience and expansive clientele for both residential and commercial CCTV installation in Kenya & East Africa Region.
Nowadays there are so many reasons that may warrant for a CCTV camera installation in kenya.
CCTV Cameras are truly the security backbone in homes and businesses premises. They provide around the clock watch and they are considered the third eye when it comes to 24/7 security monitoring.
When deciding on the type of CCTV surveillance camera system to install in your premises, there are a few significant factors you need to consider to help you choose the best security system. However, as you will see, choosing a surveillance system is not an easy task. This is because, you have to carefully think about many options before you make the final decision.
When planning for a CCTV camera installation, This should be the first factor to consider. First, Identify the most prone areas that need to be monitored. The easiest way to do this is to divide your home or business into zones. starting with the most sensitive areas.
Each zone should be allocated a single camera. Taking into consideration the maximum distance each camera should cover. This will also help determine the type of camera to install since different cameras are designed to fit different areas.
Closed-circuit television (CCTV), also known as video surveillance. Is the use of video camera to transmit a signal to a specific place, on a limited set of monitors? It differs from broadcast television in that the signal is not openly transmitted, though it may employ point-to-point (P2P), point-to-multipoint (P2MP), or Mesh wired or wireless link. Though almost all video cameras fit this definition, the term is most often applied to those used for surveillance in areas that may need monitoring such as banks, stores, and other areas where security is needed. Surveillance of the public using CCTV is common in many areas around the world. In recent years, the use of body worn cameras (body cams) cameras has been introduced as a new form of surveillance, often used in law enforcement, with cameras located on a police officer's chest or head. Video surveillance has generated significant debate about balancing its use with individuals' right to privacy even when in public. In industrial plants, CCTV equipment may be used to observe parts of a process from a central control room for example when the environment is not suitable for humans. CCTV systems may operate continuously or only as required to monitor a particular event. A more advanced form of CCTV, utilizing Digital video recorder s (DVRs),which provides recording for possibly many years, with a variety of quality and performance options and extra features (such as motion detection and email alerts). More recently, decentralized IP cameras, perhaps equipped with megapixel sensors, support recording directly to network attached storage devices, or internal flash for completely stand-alone operation or Network video recorder (NVR).

Some cameras have special protection for rain, sun, dust and even special physical reinforcement like metal housing Other cameras have high quality images Generally, when it comes to protecting your home or business, there are very many CCTV Camera types to choose from.
One of the best 24 hour surveillance cameras around providing airports, seaports, boards and many other critical infrastructures with quality images, no matter what time of day it is. Infrared cameras have small LEDs surrounding the lens to help pick up moving figures in pitch black. Thermal image cameras can see over long distances, up to 300 metres away!
This is the best type of CCTV camera for shops, restaurants, casinos and hotels because the design allows you to monitor a wider angle at your premises. Many also consider this option to be the best indoor CCTV camera as it can be placed on a strategic point of the ceiling to cover all angles of the room.
Bullet cameras are long and cylindrical in shape and are ideal for outdoor use. find us Their strengths lie specifically in applications which require long distance viewing. Installed within protective casings, the cameras are shielded against dust, dirt and other natural elements. The cameras can easily be mounted with a mounting bracket, and come fitted with either fixed or varifocal lenses depending on the requirements of its intended application.
Bullet cameras can be used to good effect in a range of industries such as manufacturing, property management and farming. They not only record good quality pictures but also send out a message to passers-by that your premises is under surveillance. That’s why they have traditionally offered the best CCTV for outside operation.
A pan-tilt-zoom (PTZ) camera works by moving the camera in different directions to get a whole picture of the surveillance area and zooming in for further detail of security events. The pan, tilt, and zoom capabilities make it possible to monitor large areas with a single camera while getting great detail at the same time.
Haven offers a wide selection of PTZ cameras for different application scenarios: high-end DF series network PTZ, AF series Turbo HD PTZ, PTZ positioning cameras, traffic PTZ, and more. These PTZ cameras work well as a standalone solution and integrated with other cameras. With Hikvision’s PTZ cameras, you can rapidly respond to security events and leave no blind spot unnoticed.

Haven DS-2TD1217-x/PA Thermal and Optical Turret Cameras are equipped with highly sensitive thermal and optical sensors and a graphical processing unit to run the video content analysis (VCA) algorithms developed by Haven’s deep learning technology.
Haven, the world’s leading supplier of innovative video surveillance products and solutions, has released its new 4MP Network IR PTZ Camera (DS-2DF9C435IH-DLW), DarkFighterX doubling the resolution of the previous model for even more clarity in dark places.
In 2017 Haven launched DarkFighter technology – taking inspiration from the way human eyes work. It uses one lens to capture the colour of objects, and another captures light details in particular. The camera then combines two images together to create one image with both colour and clarity. Now the technology has moved on, with a higher resolution, smarter event detection and a clear enough image to enable facial recognition in the future.
The new DarkFighterX camera employs 1/1.8” sensors to raise resolution to 4 megapixels. This ‘beyond-HD’ image carries twice the amount of information as 2 MP models. The camera can also deliver full colour images at light levels down to 0.0005 Lux. This also means that, in the future, facial recognition could be possible, even in dim light, thanks to powerful imaging ability and beyond-HD resolution.
Haven’s DS-2CD2012WD-I IR Mini Bullet Network Camera provides important new technology for any security application. The 4mm, 6 mm, and 12 mm lens options provide 73.1° to 22° viewing angles. The camera features an IR range of up to 100 ft (30 m) for optimal nighttime viewing, and offers IP66 water protection.
The LightFighter series delivers crystal-clear images with true color reproduction in brightly lit or high contrast environments
Haven, the global leader in innovative video surveillance products and solutions, is set to reach new heights in extremely high contrast imaging with the launch of the LightFighter series of 2MP SMART IP cameras. Each of the seven new LightFighter cameras incorporates Hikvision’s ultra-high 140 dB WDR technology for exceptional, industry-leading visibility in brightly lit or high contrast environments. The result of this cutting-edge advance is clear, detail-rich images in lighting conditions that would defeat conventional WDR cameras.
The LightFighter series consists of seven 2 megapixel cameras featuring Hikvision’s ultra-high WDR technology to overcome the pitfalls of imaging extreme backlight and high contrast scenes. The new models include a Smart IP Box camera, two outdoor Bullet cameras, two outdoor Dome cameras, and a pair of Network PTZ Dome cameras with 36X zoom. All seven LightFighter cameras are also capable of rendering Full 1920 x 1080 HD images at a consistent 60 frames per second, and boast low-light capability for night time surveillance needs.
140dB WDR overcomes extreme backlighting and high contrast
The key to the performance of the LightFighter cameras is the industry-leading WDR system that allows the camera to record greater scene details even where the intensity of illumination varies considerably, such as backlighting when very dark and very bright areas appear simultaneously in the field of view. Although a common feature in CCTV cameras for this reason, the 140 dB WDR in the LightFighter offers 100 times more powerful enhancement than the 120 dB WDR systems of conventional cameras. LightFighter is particularly suited to intense backlight situations, and is the ideal camera to point towards windows and entrance doors.
Smart Solution 2.0
The LightFighter camera range is equipped with Hikvision’s full SMART feature set, including face detection, intrusion detection, line-crossing detection, ANPR and object counting that enables the camera to detect any progressively moving object and follow it within the camera’s area of coverage without fault.

CCTV has played a crucial role in tracing the movements of suspects or victims and is widely regarded by anti-terrorist officers as a fundamental tool in tracking terrorist suspects in kenya and whole world as whole. Large-scale CCTV installations have played a key part of the defenses against terrorism since the 1970s. Cameras have also been installed on public transport in the hope of deterring crime.
A more open question is whether most CCTV is cost-effective. While low-quality domestic kits are cheap the professional installation and maintenance of high definition CCTV is expensive. Gill and Sprigs did a Cost-effectiveness analysis (CEA) of CCTV in crime prevention that showed little monetary saving with the installation of CCTV as most of the crimes prevented resulted in little monetary loss. In Singapore, since 2012, thousands of CCTV cameras have helped deter loan sharks, nab litterbugs and stop illegal parking, according to government figures.

However, an internet connection is required to enable remote viewing, motion push notifications, and to download the latest firmware updates.Every thing you need to know about CCTV cameras
Previously cameras had separate infra red light lamps bolted onto the side of their housings. It made the whole unit very large and industrial looking. In more recent times cameras have been designed with IR lighting built into them. This greatly reduces their overall size and visual impact. It also reduces cost when compared to modular cameras using separate lighting units. Many people selling CCTV cameras describe them in terms of infra red range. Do not confuse this with the optical range of the camera or the distance at which a camera can record detail. That is determined by the lens. Wider angle lenses will have a shorter optical range, more telephoto lenses a longer range. The IR range is a largely immaterial figure, often made up and is supposed to represent the distance at which the camera's infra red can be detected. In reality the ability of a camera is a combination of the lens, how powerful the IR is and how sensitive the electronics are.
Motion detected recording is a feature on all our DVR recorders. The DVR monitors camera images and decides when it thinks there is movement. To do this the DVR looks at individual image frames and compares them to the previous one. If it sees differences then motion is assumed to have taken place. It is the DVR not the cameras which is looking for movement.
A DVR isn't as intelligent as you or I and can't differentiate between background movement, changes in light and someone coming to break into your property. To help minimise false triggers it is possible to limit where on the screen the DVR looks for movement and limit this to a small area or a number of areas. You don't have to use the full screen. You can set the trigger area using the set up menu on the DVR, you can also set the trigger area remotely if the DVR is connected to your local network / the internet.
Some people only record footage when motion is detected in an attempt to extend the time footage is stored. We are not big fans of doing this. We would rather see motion triggering being used to create bookmarks within 24/7 recording rather than the sole means of capturing footage. Use it to identify which sections might be important but still have constant footage either side of the trigger.
A CCTV system will be based around a DVR or digital video recorder. CCTV cameras are connected to the DVR using cables and there will be some ancillary items such as a power supply for the cameras.
DVR or digital video recorder
DVR or digital video recorder The DVR is the heart of the CCTV system. It takes all the camera inputs, arranges them on screen for live viewing and also stores footage onto a hard drive for viewing at a later date. Our DVRs record all the cameras regardless of what you are viewing live on your monitor. It is possible to view 1 camera at a time or several camera in various combinations depending on how many channels the DVR supports. We sell 4, 8 and 16 channel DVRs which are suitable for 4, 8 or 16 cameras respectively. They can be combined, so 2 16 channel DVRs could host a 32 camera CCTV system.
Our DVR recorders also support remote access over the internet. You need to connect the DVR to your internet router. This can be done either with a cable, a power bridge adapter which uses your electrical wiring or a wireless network point. Then wherever you are in the world you can view live footage from your cameras, see previously recorded footage, make back ups of important events and even make settings changes to the DVR
CCTV cameras are the most important thing to get right and we have devoted quite a bit of space on our website to helping you make the right choice. We are always glad to offer help and advice if you are planning a CCTV system so pick up the phone and give us a call. We can have a look at your property using aerial images whilst talking through your specific requirements and select which cameras will best suit your requirements.
The cable from the DVR to the camera does 2 jobs. It transfers video from the camera back to the DVR and it supplies 12 volt power to the camera. Video connection is via a BNC connector. If you are using CAT5 cable then the BNC connector will be part of the video balun. 12 volt power connections are 5.5mm jack plugs. At the camera end there is a DC plug, at the DVR end a DC socket into which the 12 volt power supply for the camera connects. For this reason you would normally locate the camera power supply next to the DVR unit. The DVR will be supplied with it's own 12 volt power supply.
What is a PTZ camera ?
PTZ stands for Pan, Tilt, Zoom. A PTZ camera can be remotely controlled allowing it to move up and down as well as zoom in on potentially important targets. You can also program a tour between pre-set points. In theory PTZ cameras sound great, they can cover large areas and even zoom in when more detail is required
The downsides of using a PTZ camera
PTZ cameras are expensive, certainly good ones are. There are a few low quality products on the market aimed at the bottom end of the DIY market, these should be avoided. However the biggest problem with PTZ cameras is that you need a full time operator to control them. When pointing in one direction they can't see elsewhere. When the camera is moving the image will be blurred meaning you can't get any detail or identify people. So when you set the camera on a tour between preset points the image will be blurred for a large part of the recording.
Infra red illumination is often not fitted to PTZ cameras meaning they are less effective at night. It is possible to find PTZ cameras with effective IR and our PTZ cameras feature zoom sensitive IR which increases brightness as you zoom in, the assumption being you are hoping to see further away. Latency when remote accessing the cameras. When remote accessing PTZ cameras there is a delay between you asking a camera to move and seeing the result of that movement on your remote monitor or computer. This is known as latency and it can make it difficult to accurately control PTZ cameras remotely over the internet.Consider fitting more fixed cameras
Rather than use a PTZ camera consider fitting more fixed cameras for the same cost as a single PTZ camera. That way you will cover all the views all the time. You also don't need the expense of a full time operator. There are some "self tracking" cameras which identify targets and keep following them, the problem is the image will be blurred when the camera moves and how does the camera know who to track when faced with multiple targets. Thieves often work in gangs. PTZ cameras do have their uses but in the vast majority of cases you are better off using more fixed cameras.
Like everything in life CCTV is available at a range of different prices points and quality levels. You can fly on a plane for $500 in economy or you can pay $5,000 to fly on the same plane in a first class suite
The problem with CCTV is a lack of regulation and failure to understand the basic principles means people often sell systems which won't do what they claim. They sell you a first class suite but you board the plane to find yourself squeezed into a small economy seat. Actually its worse than that, they sell you a first class suite to New York but you get to sit on an orange crate whilst the plane flys to Luton.
People selling CCTV tell lies
We set up Havens as frustrated customers. We did our homework, looked at the specifications, listened to the sales patter in kenya and were very disappointed with what turned up. When you know what you are looking at the claims made by people selling CCTV in kenya are appalling. It isn't just the odd seller on ebay, it's rife across the industry. Big national retailers are misleading buyers in an attempt to get their money. When you see a camera with a claimed range of 25 metres you assume it's capable of filming something 25 metres away. You might allow a bit of artistic licence and work on 20 metres to be safe but the reality is it might only have an optical range of 3 or 4 metres.
Sticking with CCTV cameras as our example retailers often use TVL (television lines) as a determining factor in how good or bad their products are. The number of TV lines has little to do with the quality of a camera, that is more to do with the lens fitted and its optical range. Even if TVL was important retailers rarely quote TVL correctly, they advertise 560TVL cameras as 1000 TVL cameras because they don't understand how TVL is calculated.
Advice and support
We don't just sell boxes. We listen to customers needs, advise them as to the most appropriate equipment and then support them once their purchase arrives. That advice and support is vital but usually lacking at the cheaper end of the market. CCTV isn't difficult once you understand a few basic rules but most people struggle because they are mislead by false claims. Only a tiny proportion of CCTV fitted actually does what it should. We want to ensure you are are one of those small minority who own effective CCTV solutions.
TVL and IR range
People selling CCTV are often very misleading when it comes to CCTV camera range. They normally quote two figures, the number of TVL and the IR range. This might be called the night time range. IR range is a largely made up number based around how far away from the camera Infra red light can be detected. It has nothing at all to do with the effective range at which detail can be filmed.
The distance at which detail can be captured using a camera is its optical range. Unfortunately no one every quotes it, they only quote the IR range. The optical range has nothing to do with how many TVL the camera has or how bright the IR is, it all depends on what lens is fitted.
A DVR stores images as tiny dots or pixels. With D1 resolution you get around 400,000 pixels per image frame. With a wide angle lens the pixels spread apart very quickly as you move away from the camera and fewer pixels mean less detail is captured. Conversely a more telephoto lens concentrates the pixels and captures more detail further from the camera. Camera lenses are measured in mm, the smaller the number the wider the angle of view. 2.8mm or 3.6mm would be considered wide angle.
A varifocal camera allows you to manually zoom in or out during installation. This means one camera is able to perform different jobs. It can be set to wide angle or telephoto. This means you don't have to worry as much when buying the camera, you can balance the angle of view and detail captured once it is fitted. You just need to make sure you have the correct lens range, we can help you decide.
With fixed lens cameras you only get one chance, if its the wrong angle you have to replace the camera. For that reason we would always advise buying varifocal rather than fixed lens cameras.
In recent years the invention of the video balun has meant CAT5e cable can be used to connect CCTV cameras to CCTV DVR recorders. All the connections can be made using only a screwdriver, no need for special tools or fiddly components. Before you start there are a couple of important things to know.
What components do I need?
Video is transmitted along the CAT5e cable using a pair of video baluns, one at the DVR end, one at the camera end. We sell 2 types of video baluns, Standard definition and High definition designed to be used with our HD 1080P cameras and DVR recorders. Power is transmitted using using screw in DC plugs and sockets. The plug goes at camera end the socket at the DVR end. Locate the camera power supply close to the DVR.
Don't exceed the maximum cable run
The maximum distance video signal can be transferred with our video baluns is approximately 300 metres. If you are using the cable to power a camera as well as transfer video signal then we would suggest a maximum distance of about 50 metres to avoid voltage drop. This assumes you are using 3 pairs of wire for 12 volt supply and 1 pair for video signal transfer as per our images below
Use a colour convention, stick to it and check carefully
It is important to check your wiring carefully. Choose a colour convention and stick to it. In the examples below we have used blue for video signal and solid colour for +ve, white plus coloured stripe for -ve.
You need to run 1 length of CAT5e cable from the DVR recorder to each camera. The cable is going to do 2 jobs. One pair of wires will handle the video signal, the other 3 pairs of wires will be combined to take 12 volt power from the transformer located next to the DVR to the camera.
Wireless CCTV cameras
Each week we speak to a lot of people planning CCTV systems. No two conversations are ever the same but the subject of wireless CCTV and in particular wireless CCTV cameras often comes up. In theory wireless offers the ideal solution, no cables to run means installation times are reduced. So why don't we sell wireless CCTV?
Before you buy wireless CCTV cameras or a wireless system read this.
There are a number of problems with wireless CCTV. Firstly it isn't actually wireless, you still need to power the cameras via a cable. Wireless cameras tend to be fairly poor quality aimed at the lower end of the DIY market. The electronics aren't great and you only have a limited choice of lens options. Choosing the correct lens CCTV camera is the single most important factor in determining the overall quality of your CCTV system. Read our camera buying guide to understand what you need to consider when looking at CCTV cameras.
Wireless problems and limitations
The wireless link it's self often causes problems. In Kenya a lot of other devices share the relatively narrow frequency bands allocated to this sort of device. Wireless routers which stream the internet around your home share the same 2.4GHz frequency of many wireless CCTV systems for instance. Microwaves, baby monitors, bluetooth devices, structural building components, cordless telephones, walls and other solid objects are just some of the things which can get in the way of a potential signal.
Hard wired CCTV is best
A wired solution will always give the best results. It might take a little more time to install initially but you only have to do it once. CAT5 cable when used in conjunction with a simple pair of passive video baluns can transmit video signals up to 300 metres without deterioration. Switch to active baluns and that distance increases to an incredible 1,200 metres far in excess of any wireless Camera.
We get asked if we sell CCTV kits a lot and the answer is yes
CCTV systems use several different cameras
Everybody's CCTV needs will be different. Some people want cameras for outside, some for inside. Some cameras need to film overall views whilst others need to film higher levels of detail. Some subjects will be close to the camera, others some distance away. The cameras will also be fitted in a variety of different locations. You begin to see that a one box solution can never provide a good CCTV solution. The most important thing to get right on a CCTV system are the cameras. We have a guide to choosing CCTV cameras elsewhere on the site.
The CCTV kits you see advertised all contain fixed lens wide angle cameras. The single worst thing you can do is use fixed lens wide angle cameras because they spread pixels apart as you move away from the camera and you don't capture any detail. They may claim an effective range of up 20 or 30 metres but the reality will be nothing like that, probably 3 metres in standard definition.
Cables and connections
Cable distances will vary from application to application so the likelihood is whatever cables came in the box would either be too long or too short. In fact pretty much every element of a CCTV system needs to be tailored to the user's needs. All in one box CCTV kits often have unique connectors to that particular kit meaning if you need to change a camera you can't because no one sells equipment with those fittings. The result is everything goes in the bin and you have to buy a completely new system.
CCTV kits tend to be very poor quality. You don't have a choice in how good or bad each element is, you simply get what's in the box. Because they are sold to a price one box CCTV systems tend to contain decidedly average quality equipment other than the outer box it's self. That will be bright, colourful and contains words such as professional, high quality, razor sharp, pinpoint, high definition and so on. They almost spend more money on the box than the contents!
Buy what you need
We allow you to choose elements of your CCTV system individually to make sure you end up with exactly what you need. Save money in areas where conditions are less demanding, buy the right gear for the job where things get a little tougher or results are more critical.
We still reflect the fact you're not just buying a single camera by including a free power supply when you buy 4 cameras. We fit the hard drive into the DVR recorder, format it and configure the DVR settings free of charge to save you having to wade through a 60 page instruction manual. We also include a good quality warning sign pack should you need one. Remember we are happy to offer free help and advice to make sure you buy the right kit.
