Instructions for installing a wired security camera system

You have grasped the characteristics as well as strengths and weaknesses of wired security camera systems and Wi-Fi. Our company will briefly talk about how to install a wired security camera system as well as notes during the installation. Basically, the process is not simple, but the benefits it brings will be completely worth the effort that you put in. Below is an overview of how to install a wired security camera system.

The system used in this instruction is Camera Haditech HC-AB2004 which comes with a DVR box that supports 24/7 recording. In general, no matter which system you use, the installation process is basically the same, of course there are a few minor differences depending on the system you use but not too much.

Step 6: Connect the parts together.

Step 7: Set up the user interface.


Preparing tools

Unlike simple WiFi cameras, you will need more tools to install a wired camera system, including:

Ethernet cable

Jack Balun (Support converting analog signals into digital signals, recommended if your wired security camera system uses analog).

An electric drill with a full range of drill bits


Monitor, mouse and keyboard

An "assistant" (this is really necessary)

You will know which tools to use and how to use them after starting the installation process depending on the particular situation. However, the equipment listed above are the most basic you will need to have.

Map overview and installation of a wired security system camera



Before the process of placing a wired security camera system, you must first understand how the components of the system are interconnected.

Most wired security camera systems will have basic equipment consisting of several cameras and a DVR that acts as a user interface for managing the entire system, as well as storing all the recorded scenes.

All cameras connect directly to the DVR, or use a BNC cable (for analog camera systems) or an Ethernet cable (for digital systems). If you have an analog system, it is better to use special adapters called balun instead of traditional BNC cable. This adapter allows you to use Ethernet cable as it is easier to install and more modern.

Because the cameras are all connected directly to the DVR, so assuming you install the camera in the backyard while the DVR is located upstairs in your bedroom, you will need to route the camera cable through the house to connect to the DVR, it can be a bit complicated, so depending on how your house is built, you will plan the cable wiring correctly, which is time-saving.

Place the DVR near the power outlet to limit the messy wires. Then you connect the monitor to the DVR to manage the whole system and also view all the live images from both the cameras and review the previous recordings. Most systems will also come with a mouse, but you should also prepare a keyboard.

Step 1: Locate the place you want to Install Security Camera

The difference between the wired security cameras and Wi-Fi cameras is that you can not put the camera anywhere. On the contrary, you will have to carefully consider the appropriate positions to place the camera so that you can both have a view of the important areas, while making the cable less complicated.

For example, it would be nice to have a camera mounted on the wall in the upper corner of the doorway, but you will need to think about how to route the cable from the camera to the DVR located far in the bedroom on the second floor. This is also a limiting factor you will face when installing a wired security camera system. So instead of mounting the camera on the wall on the outside, maybe mounting it to the ceiling of your porch would be better since you it might be able to place the cable along the awning and then go through the 2nd floor window where the DVR is located - obviously it’s  much easier. In summary, mapping the camera location and wiring is paramount, directly affecting the entire installation process.

Note, choosing the location to install CCTV to ensure the following factors:

Camera has the best viewing angle, covering the entire area and looking to the position to be observed

 Finally, drill and hold the stand, attach the camera to the bracket. Then we will move to the next step: wire the signal to connect the camera to the video recorder.

Step 2: Prepare to install the camera

          Depending on where the camera is exactly located, you may need some other assistive from the list listed above. For example, if you just need to drill through wood, drywall or aluminum frames, a regular electric drill and a few basic drills will suffice. However, if you have to drill through bricks or other concrete blocks, you will likely have to prepare specialized drills.

First, you'll have to mark the hole where the camera cable will go through, as well as the camera screw holes. You can try the camera on and then mark the holes with a pencil.

Then you drill screw holes for the camera and then drill a larger hole for the cable. Hence the preparation of drill bits of different sizes is essential.

          Depending on the type of camera and the technology, the installation distance will vary. With new analog cameras such as HD-CVI, the installation distance can range between 300m (for Full HD cameras) and 500m (for HD cameras).

Step 3: Connect the cable to each camera mounting position.

Once you have drilled a hole of the right size, it is time to connect the cables to the camera locations. The order of wiring for each location depends on the actual situation, but basically you will have to calculate how to take the cable properly, avoid drilling and go underground a lot, which will also affect aesthetics such as making it difficult to dismantle and replace it later.

Step 4: Connect the cable to the DVR

After you successfully connect the cables to the camera locations, now is the time to connect all those cables to the DVR.

You will need to drill holes for wiring again, this is also the most complicated step so if possible call a few more friends to help you. Ideally you should converge the cables and let it go through a hole before going into the DVR box. Depending on the actual situation, you can choose a suitable location for the DVR box. Most DVR boxes will have mounting holes on the back for wall mounting. Alternatively, you can also place them at your desk or somewhere else.You can use tape to fix cables to walls and ceilings.

Step 5: Install the camera

At this point, everything becomes a lot easier because connecting the cables is definitely the most complicated part. Installing the camera only takes a few minutes.

First connect the cable to the camera. For safety, you can wrap the connection points with insulating tape in case of electrical leakage.

Next, take out the screws and attach the camera to the surface. Once the camera is fixed to the surface, you can adjust the camera's direction and visibility by loosening the screws and then tightening them when all adjustments have been made. Noted that to save the effort of adjusting many times, it is better to adjust the camera direction after the whole system is in operation because then you will know if the camera is obscured or not and if camera placement is reasonable.

Step 6: Connect the parts together

After wiring and installing the camera, you can now start connecting them to the DVR.

Connecting parts is usually not too complicated and there are specific instructions. In general, just connect each cable to its own port, then connect an external monitor as well as a mouse and keyboard to the DVR. You can also plug in a USB in case you need to export recordings quickly.

7. Audio port used when you want to record sound.

Step 7: Set up the user interface

The UI installation process may vary depending on the system you use. In the example system, the user interface setup consisted of creating a password, setting the date and time, and a quick guide on how the system works. You should take some time to research some recommended custom settings, for example whether your camera should record 24/7 or only record when there is motion. In addition, you can also customize the quality of the recording.

Above is a summary of how to install a wired security camera system for the home. Good luck!
