How to Install Cctv at Home? (Do It Yourself Guide)

From the early days of Surveillance systems to the recent past, everyone depended on qualified technicians to install CCTVs. Reason being, the surveillance technology at that time was so complex such that it actually involved the use of built-in video cassette recorders and a chain of wires running from the recorders to the cameras. To make is worse, the entire installation process was only understood by trained technicians. But thanks to the advancement in technology; nowadays, CCTV installation has been made affordable and too simple for absolutely anyone. Having said that, how can you install CCTV at home?

Here’s the guide:

Step 1: Getting the right cables

Before you embark on the installation process, you'll be required to get the right cables. In this case, you'll have to get RG 59 cable . Generally, this cable contains a power cable and a video cable all encompassed in one; hence the name Siamese.

Step 2: Determining the number of cameras you need and their right locations

Next, you can survey your home to determine the number of cameras you'll actually need and their suitable locations, as well. Alternatively, you can use special design CCTV software to select suitable locations for your cameras. A good example of such software is the IP-Video-Software-Design-Tool, which allows you to import the site plan of your home before adding the cameras. The software will then present you with appropriate angles of view, 3D mock ups and the required focal lengths.

Step 3: Placing the cameras

Once you've determined suitable locations for your camera, you can now proceed and install them (minus the cables, of course). Usually, it's recommended that you install the cameras where the walls meet the roof--to protect them from the elements of weather: sun, rain and wind. Apart from that, installing your cameras near the roof will give you the best field of view and, at the same time, help you keep your cameras safe from vandalism. Lastly, this location will also give you a simple run for your cables since it's always easy to trace gaps where the roof meets the walls.

Step 3: Choose A Place To Keep Your DVR & Monitor

At this point you can designate a single room to station your DVR and monitor. This can be your bedroom, study room or any other room that's accessed by a limited number of people. To stay safe, we recommend that you keep the whereabouts of your cameras vaulted to only you or the trusted members of your family.

Step 4: Connecting the RG59 cables from the cameras to the monitoring room

You can now connect the RG59 cables from camera to the monitoring room by passing them through the attic. If you purchased the cables with their BNC connections attached, you can connect them directly to your DVR. But if the cables came without the connections, you'll be required to buy them and have them crimped at the end before connecting.

Step 5: Connecting the cameras to power

Generally, these cameras are powered by DC voltage. And there are actually two ways you can use to get these cameras connected to power. One, you can connect each camera's power line directly. Two, you can buy an AC/DC power-supply box to plug in all the power lines from the cameras before connecting the box to an AC outlet.

Please note; the DC voltage you supply to your cameras should be as exact as specified by the cameras’ manufacturer; or else, you might end up damaging your cameras.

Step 6: Connect the DVR to your monitor

Now you have you cameras and power lines connected to a DVR. The next step should be to power your cameras, the DVR and the monitor. But before you turn on your power supply, you should first ensure that the DVR is connected to the monitor. After turning on the power, you can test drive your CCTV system to see how it works. Try to adjust your cameras where necessary to get the best field of view for your home. Similarly, if you feel like your home needs other cameras, just follow the same guideline to install them.

Now, as you can see, installing CCTV in your home is way easier and fun than you could have possibly imagined. If you follow these guidelines correctly, while paying a close attention to subtle details like voltage or location, nothing will definitely go wrong even if you consider yourself technologically challenged.
