The thought of making holes in the walls or to stream all the videos of your personal space may be nerve-racking at first. The task might also seem humongous and not worth it. The security system like the CCTV cameras are quite easy to install and the installation process of the security system is a cakewalk.

In this article, we have discussed all the steps which you need to follow for installing a camera system at your own house.

Prepare your House

Make a diagram of all the areas which need surveillance

Years of experience have shown that it is pointless to install cameras for every corner of your house. It also becomes expensive to install that many cameras in your home. Therefore, you need to figure out which areas in your house need monitoring.

To make this process simple, you need to draw a rough sketch of your house and figure where the cameras need to be placed. When decided, you need to check that the view of the camera is not blocked and the camera is positioned to get the best view.

Here are some places where you might want to install the cameras.

  • The doors, both front, and back
  • Windows
  • Common spaces like kitchen and living rooms
  • Porches
  • Driveways
  • Stairways

Go for the package which caters to your needs

You can buy each part of the security system individually. But, it is usually cheaper if you purchase all the parts together and bundled systems of security. For the minimum package, you have to purchase 1 to 3 cameras, appropriate wiring (BNC and siamese), power cords, and a DVR (digital video recorder. If you do not require a large area, you need to cover a large area, mounting wireless cameras to your walls will be all you need.

  • Basic home security: Get a deal of 2 to 3 outdoor cameras to survey on the doors. It should come with a DVR and support at least three days of recording.
  • Looking on children or valuables: Get 1 to 3 wireless cameras that can easily cover a small room. You can stream the footage directly from your computer.

You can also buy cameras individually

When you know how many cameras you require for the surveillance, the next thing to figure out is the types of cameras you require for it. The home surveillance system can range from a few hundred dollars to thousands of dollars.

The features of all cameras are labelled clearly under a box. So, you need to carefully read it before buying the camera. You can buy the parts individually but if you buy the whole set together, it is usually cheaper. Also, the process of installation becomes easier.

  • Wireless and wired: The wireless cameras are easier to install but the quality can be inferior. If you have to cover a bigger area, then the wireless cameras can pose a problem. However, most houses find that the wireless cameras are more suited for them.
  • Indoor VS Outdoor: Cameras that are meant for indoors will break in case of rain or strong wind. You should choose wisely.
  • Motion sensing: Some cameras with this feature only capture when there is movement in the room. This saves space in the drive and records only when people are in the room.
  • Remote viewing: Many cameras enable the user to view the footage on their mobile phones from anywhere in the world. They do this with the help of a special app.

Install a monitor or recording device 

You can buy DVR or VCR according to your convenience. You can also stream all the footage on a monitor. The cameras also have a memory capacity which enables them to store footage for you to view later.

If you buy a full set, a DVR is usually given with the cameras.

Check all the parts before installation

You need to make sure that all the equipment works well before installing them. You need to connect the cameras, cables, and monitor before installing to be sure that they are not faulty.

Installation of the cameras

Select a broad, high angle

The best place for the camera to fit is that corner where the ceiling meets the wall. You need to install it in such a way that the camera looks down. Also, you need to be sure that all the entries and exits are clearly visible. The camera should also be near the power outlet.

Set the camera to the wall

Some cameras are instructed to use the adhesive to stick them to the walls. However, screwing them to the wall is the safest way to install them. We know that all the cameras are different but the process of installing them are quite similar.

  • Place the mount on the required location.
  • Make marks on the wall for the screws to be drilled.
  • Drill a screw with the help of an electric drill.
  • Secure the molding pins by hammering.
  • Put the camera in the secured angle.

Connect the camera to the power source

Mostly, the cameras come with the power adapter which fits in the usual wall socket. You just need to plug the round, small end in the power input situated in the back of the camera to the end of the outlet.

If the adapter is missing or broken, you need to contact the manufacturer.

Attach all the cameras to the DVR

All the surveillance equipment can be connected using the BNC connection. These cables are simple to handle. They are identical on all the sides so they can be connected to the required port. You have to connect one to the output of the camera and the other to the input of the DVR.

Link all the wireless cameras to the computers

The wireless cameras are given with a software disc and you need to install it to your computer to access the feeds. You need to follow the instructions that are provided in the manual.

  • Some of the cameras come with tiny receivers and are connected to the computer using an USB port. You need to make sure that the cameras are properly attached.
  • You can write the computer’s IP address so that you can just type that number to access the stream of the camera from anywhere in the world.

Connect the DVR to the monitor

You can connect as many cameras you want to the DVR. The maximum number of cameras means the maximum number of inputs the DVR has. Then, you have to plug in all the cameras to the input of the DVR. After that, you need to connect the DVR to the computer.

Connection issues

If there is any problem, try turning all the systems down and then turning all of them on. Some monitors will display the videos of all the cameras at the same time. Other monitors have input buttons that allow you to connect different cameras at different times.

Consolidate the Surveillance

Make a central hub for surveillance 

When you are wiring a lot of cameras at one time, you need to find a common junction to connect them all. This central connection needs to be connected to your DVR. This junction should be easily available from all the areas of your house. The basement or the attics are good places for this junction.

The internet router can also be another alternative for the junction. You only need to have one DVR for all the cameras.

Use Siamese cables to wire the system

The most common type of cable to use for the surveillance cameras are the siamese cables. There are two cables braided together, one is for the power and the other one is for the video.

The power supply box can enable you to connect multiple cameras to one outlet

The power box allows you to power all the cameras through the single wall outlet. They are also a cheaper option. You must make sure that all the cameras are attached before placing the power box to the wall.

Select different DVR port for each camera

One input port should be selected for each camera. You can connect all the cameras to the same DVR by using all the ports of the DVR. Then, the DVR should be connected to the monitor where the streams from the cameras can be viewed at the same time.

Hide the wires

If you want the installation of the cameras to look professional, you need to hide all the wiring. You can do this by camouflaging the wires with the same colour as the walls. You can also hide them by hiding them under the rugs.

If you find it very difficult to install the security system for your homes, you can call the professional to help you out.
