Step 1: Mounting

There are three basic parts for installing a security camera. The first thing you must decide when installing a security camera is where to mount it. Try to mount the security camera somewhere high enough that if someone would want to tamper with it they won’t be able to reach it from ground level. If this is going to be an indoor security camera it is best to place the security camera at the corner of a room.

A dome security camera equipped with a standard 4mm or 3.6 mm lens will give you an 85 degree to 92 degree view angle which will allow you to cover most rooms with one security camera. Now if the security camera is going to be an outdoor security camera, make sure the security camera is weatherproof and features an infrared LED function for night time viewing.

Step 2: Powering

The second thing you must take under consideration is how you’re going to power this security camera. All security cameras have two cables that need to be connected for it to work. The first cable is for power and the second cable is for video. If you are mounting a security camera and you have a power outlet near the security camera then you won’t have to worry about this. Most of the time this won’t happen: most likely you are mounting the security camera somewhere that won’t have any power outlet nearby.

When installing security camera and you know the distance of the security camera is 100ft or less from your viewing or recording device, you can use an RCA cable for all installations of security cameras. If the security camera is further then 100ft we’ll recommend that you use Coaxial Siamese Cable (power and video bundle into one cable) to make it easier to run one cable (rather than two). In this situation what you must do is purchase a male power adapter connector (known in the industry as male “pigtail”). This will allow you to get the power source from somewhere else and not necessarily at the location of the security camera.

Next, you will connect the pigtail to the power connector on the security camera. At the end of the pigtail there will be two open wires one for positive (all black with white line dash) and one for negative (all black). Connect the correct wire to the Coaxial Siamese cable power connection: positive goes with positive and negative goes with negative.

At the other end of the coaxial cable connect a female pigtail to the two open wires of the coaxial cable and repeat the same step, positive going with positive and negative going with negative. You have just bridged the distance needed for your security camera to give it a power source. Just plug in a 12V power adapter (make sure you get the right amp that your security camera requires because some infrared security camera requires more amps to power the infrared LED) to the female pigtail connector and you are done with power.

Step 3: Connecting to output

The last thing you must do when installing a security camera is you need to connect to where the video will either be viewed or recorded. To connect the video you will need BNC connectors: one at the security camera and one at the recording or viewing end. To view a single security camera you can connect that directly to your VCR and then to your TV but you need to get a BNC to RCA adapter. For multiple security cameras we recommend that you use a standalone DVR (digital video recorder).

With the technology of today, and standalone DVRs being so reasonably priced, you should always consider this option. The best part about using a standalone DVR is the remote viewing. This function will allow you to remotely log into your security system from anywhere on the planet via the internet.
