What is a CCTV Analog Camera System?
CCTV Security Systems, also known as Analog Cameras, are a network of cameras installed to record videos and store images that are transferred to a specific audience.
CCTV Analog systems are viewed and used by homeowners and businesses that desire to observe and prevent theft, suspects, robberies and other illegal activity. This can be especially helpful during criminal investigations. They can also be used to check up on family, staff and people ringing the bell when you are not at home – giving you peace of mind.
Bear in mind that CCTV Analog cameras are connected directly into the DVR (Digital Video Recorder) box, meaning that if you wish to install 4 cameras in different rooms, or both inside and outside, you will need to connect all 4 cables through your house in order to connect them to the DVR box.
How do you install a CCTV Analog System?
To install 4 CCTV cameras in your home, you will need:
- 4 CCTV Analog Cameras
- CCTV cables (RG59 Siamese Coaxial Cables)
- A DVR (Digital Video Recorder)
- A power supply (1 amp per camera) - to be installed as close to the camera as possible
- 8 x Male BNCs
- A Dedicated Monitor (or the DVR can be connected to your TV) – to view footage
- A hard drive with a capacity between 500MB and 5TB (to record the images) – to be installed into the DVR
- A drill
Running the cables is the most demanding and time-consuming part of the installation so it is advised that you take your time and try do it right the first time.
Set up the power supply as close as possible to where the DVR is located, as one part of the cable goes to the DVR and the other goes to the power supply.
Pro Tip: Keep in mind how long the cable runs are. On most Analog systems, problems usually occur when the cables are too long for the power supply, or too many cameras are running on the same power supply. Ideally, you should install the power supply as close to the camera as possible (if the camera is situated more than 50m away) and run the signal camera back to the DVR. At night-time when the Infrared turns on, the cameras use more power, which can cause the power supply to shut down.
For shorter runs, install your cameras at the desired destination at a downward angle. Recommended areas to install your cameras are: above front and back doors, garages, nurseries and any other access points or concealed areas.
Drill holes through the walls or ceilings where the cables will feed through and where the cameras mounting screws will go.
Pro Tip: Use fish tape to help manoeuvre the cables through the walls and ceilings.
The next step is to attach male BNCs onto each end of the RG59 coaxial cables. As the RG59 splits in two, one part goes the DVR, a.k.a RG59 cable, and the other part goes to the power supply, a.k.a power cable.
Connect the one end of the RG59 cable to the DVR box, and the other end to the video output of the camera cable.
Then, connect the one end of the power cable of the RG59 to the power supply, and the other end to the camera's power plug input.
Use a junction box to protect the cables.
Once all the cables are connected, connect the Dedicated Monitor to the DVR box. Then set up the DVR to record on motion or events.
To view images and videos on your smartphone, you will need to run a cable from the DVR to the internet port and router (WAN), and configure the settings.
