CCTV - Installation Guide Do-It-Yourself
This guide is written for those who need video security and can not afford costly installation services at times, or if the installer of CCTV cameras is not available in your area - then it is more common than you might thinking. We cover the most common types of safety equipment, because it is virtually impossible to go beyond a broad range of different security cameras and recording / video available on the market.

I suppose that anyone considering the installation of CCTV do-it-yourself has a basic knowledge of wiring techniques and practices. I am not responsible for damage to equipment caused by improper handling or abuse. Remember, during the installation always pay attention to safety. Work at heights and using tools can be dangerous, follow all safety practices. Let's jump to it now.
Planning:
The first step of any camera installation is to plan the location of the camera and surveillance equipment. When planning for camera locations please take into account the conditions of light, never install cameras in low light room pointing straight to the sunny area that will add to the brightness of the image, even if the camera has a copy light compensation will not suffice. They use infrared cameras for very dark conditions, and / or cameras B / W with the smallest possible number of LUX. I will not discuss the selection of appropriate equipment, as has been the subject of my last article.
The choice of the best locations will not be easy, and it directly affects the point of view of the camera. In addition, lighting conditions, distance from the object of control is equally important. There are many different focal lengths and lenses, the choice depends on the lighting conditions and distance from the camera to follow the target. In small rooms around 500sq. Cameras feet, 3.6 mm standard lens should be OK. Keep in mind that most of the bullet and board type cameras come with 3.6mm lens, the greater the distance from the target follow-up longer focal length is necessary. There is no easy way of judging lens selection, you can eider guess or buy professional lens selection tool .. Alternatively, you can begin the selection of the lens and, if necessary, to have a more or less long focal length later. Another option with regard to the lens selection goes, is to use a variable focus lens, which is a very versatile approach and takes the lens to guess the selection process.
To maximize coverage of the cameras and make the most of the video surveillance system for less money to minimize the number of cameras placed in strategic places, unless the entire coverage area is needed. Avoid overlapping views of the camera, do not install the light source directly in front of it and do not place infrared cameras pointing at each other to eliminate the risk of overexposure. These are the most common mistakes should be avoided. After the initial camera locations are predetermined, lets look at the placement of cables. Make sure it is possible and practical to run cable to each location, using the cable into any position of the camera for some reason you can not choose not to another place.
Wiring: The most important of all long and camera installation is wiring. Plan your installation carefully to minimize cable lengths and provide a good quality of the video signal. Never drive cables from high power electrical lines, at least 12 "distance between the video cable and power lines are recommended. Keep the cable lengths below 400ft and use good quality cable, most people take the cable for granted, but it is actually very important aspect of any installation. CCTV system is only as good as its weakest link. I usually stick with RG59U with power Coleman Cable ( yes, it is done in the U.S.), also called Siamese type cable. It is combo cable and transmits the video and power, as an alternative, it is sometimes possible to use less expensive RG6 standard coax cable with 18/2AWG separate drain for power.
