CCTV Installation

CCTV, which stands for closed-circuit television, is becoming common in modern society. It is used as a security system in homes and businesses. Before considering doing a CCTV installation yourself, it is important that you have good knowledge of wiring techniques. Damage can, and does occur due to mishandling or misuse. Safety should always be on your mind during the installation process.

 

Decide Where You Want To Install the Device

The first step in the process is to plan where the camera and monitoring equipment should be located. When deciding camera locations, be sure to consider light condition. You should never install cameras in a low light area pointing straight into a sunny area as this will add glare to the picture. For very dark conditions, the use of infrared cameras is recommended. Apart from light conditions, it is also important to consider the distance to the monitoring object. After selecting the initial camera location, you’ll need to determine the best location for cable placement. You should ensure that it is actually practical to connect cable to each location, and if not, then look for an alternate location.

 

Plan the Wiring Properly

This is the most important, and probably time consuming aspect of any CCTV installation. You will need to minimize cable lengths and ensure good quality video signal. Make sure you run cables at least 12″ spacing away from power lines, and also keep the cable lengths under 400ft. After the cable is in place, the difficult part of the installation process is over, and it’s time to move on to the mounting of the camera.

Mount the Camera in the Appropriate Location

Most CCTV devices come with mounting tools and supplies including screws and bracket. Attach the bracket firmly and be sure it is well secured. Affix the camera properly to the bracket and then adjust the position appropriately. There are two conductors on the power cable and many of them are red or white and black. Use the black for negative and white or red for positive terminals. Check to see if it comes with screw or push terminals for power input and then connect the cable directly paying attention to polarity.

 

Connect the Monitor and Recorder

After mounting the cameras, it’s time to connect the monitor and recorder. You’ll need to setup a rack, desk or shelf to hold all the equipment. Once the monitor and recorder are in place you can then determine the proper location for power supply. Mount power supply within a few feet from the DVR video inputs and make sure it is securely in place. Next, run the power conductors to power supply. Be sure to observe the polarity as each terminal is marked, and there shouldn’t be any doubt. Don’t plug in the power supply to the power outlet yet. Next, the video Cables need to be connected to the DVR video in ports. One video cable should be connected to the DVR with the monitor. The DVR monitor out port should be connected to monitor video in.

 

Protect the Equipment

Before you power on the equipment, it is important that you protect it from power spikes. To do this, plug the equipment into power conditioner or buttery backup unit. The backup unit is recommended if the installation location experiences frequent power outages.

 

Power on the Equipment

Now that the installation is complete, it is time to power on the equipment and make final adjustment. Turn the power supply of the camera to the on position, and also turn the monitor on the DVR system as well. Examine each camera view to be sure the view is actually the way you want it, and make any necessary adjustments. The test monitor is an essential tool that will help to properly adjust the positions. Go to the location of each camera and with the test monitor connected, you can easily adjust the position of the camera to your preferences. Once you’re satisfied with the adjustment, make sure the camera bracket adjustment screws are securely in place.
