Power supplies
CCTV power supplies are essential components of any video surveillance system. They provide power to cameras and other devices, such as recorders and switches. There are many different types of CCTV power supplies available, and the choice of the right one depends on the specific needs of the installation.
Basic Types of CCTV Power Supplies:
-
AC Power Supplies: Plug into a wall outlet and convert AC mains voltage (230V) to the required DC voltage (12V or 24V) for most CCTV cameras.
-
PoE (Power over Ethernet) Power Supplies: Power cameras using an Ethernet cable, eliminating the need for separate power cables.
-
UPS (Uninterruptible Power Supply) Power Supplies: Provide backup power to cameras and other devices in case of a power outage.
Factors to Consider When Choosing a CCTV Power Supply:
-
Output Voltage: Ensure the power supply provides the correct voltage compatible with the cameras and other devices.
-
Output Current: Choose a power supply with sufficient output current to meet the power demands of all devices in the system.
-
Number of Channels: Some power supplies have multiple channels, allowing multiple cameras to be powered from one unit.
-
Cable Length: Consider the length of the power cable, as voltage drops can occur over long distances.
-
Additional Features: Some power supplies offer additional features, such as overvoltage protection, short circuit protection, and remote control.
