DVR (Digital Video Recorder)
The DVR serves as the control for the whole CCTV system. It coordinates all this processes with the aid of a DVR software.

CCTV Video Storage Hard Disk Drive
A hard disk is used for continuous storage of CCTV video files. The hard disk is housed inside a DVR.
Normally, hard disk comes in various storage capacities, and are sold separate from the DVR.
Common capacities include 250GB, 500GB, 1TB, 2TB and so on.
Most of the commonly used hard disk are SATA (Serial Advanced Technology Attachment) type.
Because CCTV hard disk are intended to run continuously for long duration’s, they are of a superior quality as compared to the ordinary ones used in computers.
Factors to consider when choosing a Hard Disk for your CCTV System.

CCTV Camera Power Supply Unit
For a CCTV camera to function, it must be supplied with DC power.
This is the work of the power supply unit.
There are different types of power supply available and the choice will be determined by the type and the number of cameras in a system.
A CCTV camera can be supplied with power on its own, or it can be supplied from a central point.
DC Power Connectors
The DC Power connectors are used to connect the camera to the power source
This connector is supplied as either male or female connector.
CCTV Installation Cable
CCTV cameras requires a special cable to transmit the signal from the camera with minimum signal losses.
A standard cable that is used for this function is the RG59 CABLE, also known as the siamese cable.
This special cable is specially made for CCTV installation.
It comprises of A coaxial cable which is attached to a power conductor cable.
The coaxial cable is for signal transfer, it comprises a thin copper conductor surrounded by a thick plastic sheath,which is then surrounded by a mesh braid of a copper conductor.
This braid help to reduce interference to the signal.
The attached power cable comprises of two insulated copper conductor, and is used to supply the camera with power in a case where a central power supply is used for the CCTV system.
BNC Cable Connectors For CCTV Installation
The BNC (Bayonet Neill–Concelman) connector is a special Radio Frequency signal (RF Signal) connectors made for quick connection of
They are used to connect the coaxial cable to the camera and the DVR.
The BNC connectors are usually supplied in two versions for 50 Ohms and for 75 Ohms Coaxial cable.
Termination boxes are plastic or metallic enclosure used to enclose the cable termination connectors near the CCTV camera during CCTV installation.
The enclosure help to prevent the connectors from moisture, physical damage, and also make the installation work more neat and organised
by housing together all the loose cables.
Also, In a case where a power supply is mounted near the camera, it is used to house the power supply unit.
Cable Clips/ Conduits / flexible conduits.
When running a CCTV Cable, There has to be a means of holding the cable to the wall or else the cable will hang loosely which will make
work unappealing, and will also make the installation suseptible to vandals
For this reason, cable clips, also known as tower clips can be used to attach the cable on the wall.
Other methond that can be employed include using conduits. This can be fixed externally, or can be put under conclete during
the house construction.
If however the camera is installed in an ackward hard to reach place, a flexible conduit can also be used.
Display Monitor Unit
In order to view either the live footage or the recorded footage from a CCTV system, It must be connected to a display monitor unit.
A display monitor unit used can either be a small monitor or a big display unit depending on the size of the system.
For networked CCTV systems, the footage can also be viewed on mobile devices and computers.
Power Backup System for Uninterruptible operation.
If you have a problem with power interruptions, you may consider a power backup for your CCTV system.
A power backup ensures you have a continuous monitoring even during power outages.
However, when purchasing the UPS for CCTV system, its wise to consider the time it can run in case of a power outage vs the cost.
Big backup system which can run for several hours of a power outage is expensive and its good to plan accordingly.
When finding a place to place the CCTV DVR, its good to allocate it near a power source.
This will help to avoid extra charges buying electrical extension cables.
Secure Housing For DVR
