Remember during the installation always pay attention to safety. Working at heights and using tools can be dangerous please follow all safety practices, lets jump right to it now.
Planning:
1. When planning for camera locations please take in consideration light condition, never install cameras in low light room pointing straight into the sunny area it will add glare to the picture, even if your camera has back light compensation it will not be enough.
2. Use infrared cameras for very dark conditions and/or B/W cameras with as low LUX number as possible.
3. Selecting the best possible camera locations is not easy, which so depends on light condition and distance from the camera to the monitoring object. Keep in mind that most bullet and board type of cameras come with 3.6mm lens, the greater the distance to the monitoring object the longer focal length of the lens will be needed.
4.do not install cameras with source of light directly in front of it and do not place infrared cameras pointing at each other to eliminate risk of overexposure. These are the most common mistakes that need to be avoided.
Wiring:
1.Plan your installation carefully to minimize cable lengths and insure good quality video signal.
2.Never run cables alongside high power electrical lines, at least 12” spacing between video cable and power lines are recommended.
3.Keep the cable lengths below 400ft and use good quality cable.
4.Using Siamese cable makes for more clean and neat installation.
5.it is good practice to leave couple of loops of extra cable at both camera and monitoring locations. This extra length of cable is needed if in the future monitoring or camera location will have to be moved slightly.
Camera mounting:
1.Most cameras come with mounting screws and bracket included, attach the bracket firmly.
2.. Most cameras are 12VDC, in this case it is important to observe polarity or you may damage the camera.
Monitor and recorder connection:
Cameras are on, it's time to make final connections. I will focused on standard CCTV monitor, standalone DVR recorder and distribution power supply, as this is the most popular and likely solution for most CCTV installations.
1 we have to install BNC connectors on this side as well.
It is good idea to make room for monitor and recorder now and setup some type of desk, shelf or rack to place all the equipment on.
2.We need the monitor and recorder in place so we can determine proper power supply location.
3.Power supply should be mounted within couple of feet from the DVR video inputs.
4. Make sure the power supply is not plugged in to the power outlet yet.
5.Connect video cables to the DVR video in ports.
6.Connect the DVR monitor out port to monitor video in.
We need to protect the equipment from power spikes by plugging it into power conditioner or better yet buttery backup unit.
Power on and final adjustment:
Yes… we are now ready to power it up for the first time, if this is your first installation it may be nerve-racking experience.
1.Start with turning the cameras power supply on; turn the monitor on as well followed by DVR system. The stand-alone DVR after self-test will show cameras or setup menu on first power up depending on your model.
2.To setup the DVR refer to the manual for proper settings.
3.Go over each camera view to determine if the camera view is actually what you want.
A good CCTV system defines the area's level of security. It provides evidence in catching the culprits red-handed. They provide a sense of safety to an area, in that persons who know that their actions are being watched will avoid a deed that might incriminate them.
