How to Install a Security Camera System for a House

The idea of drilling holes through the walls of your house to run video and power cables for a security camera system might seem difficult and daunting; however with a little bit of information you might find it to be fairly simple and an enjoyable project.

Method 1 of 2: Finding the right location for your cameras


1. Look where the roof meets the walls of the house. This is a good location because it shelters the cameras from the elements (Wind, rain, snow and sun).
  • Also when placing the cameras near the roof it gives you a good area of view and minimizes the risk of vandalism.Install-a-Security-Camera-System-for-a-House-Step-1Bullet1
  • Another advantage is when you’re running cables (Power & video) it makes the job easier because many homes have a small gap or hole where cables can be ran between the roof and the wall.Install-a-Security-Camera-System-for-a-House-Step-1Bullet2

Method 2 of 2: Cabling

1. The best idea is to use the industry standard, RG59 Siamese Cable. It is the type of cable used to run most CCTV installs. This cable consists of one video cable and one power cable (Positive and Negative), thus the name Siamese.


2. Now you need to find a point of entrance from the outside of the house to the inside. Most homes have an attic which is a great place to run all your RG59 lines into.


3. From the attic, designate one location for your DVR and Monitor to be stationed.

4. Bring all the RG59 lines into that room from the attic.

  • If you purchased the RG59 cable with the BNC connections already attached to the line then at this point you would connect it to the DVR. If you purchased a bulk roll of RG59 without connections you would need to purchase the BNC connections and crimp each end on, then connect it to the DVR.Install-a-Security-Camera-System-for-a-House-Step-5Bullet1
5. As for the power you have two choices.
  • You can run each power line separately into an outlet (using pig tails) and an AC Adapter.
  • You can get a power supply box and plug all power lines into the power supply and from there you have only one power line which goes into the outlet.Install-a-Security-Camera-System-for-a-House-Step-6Bullet2Install-a-Security-Camera-System-for-a-House-Step-7

6. Now that you have your video and power lines connected all you need to do is power the DVR and attach a Monitor to the DVR (Of course the monitor also needs power).Install-a-Security-Camera-System-for-a-House-Step-8
