Independent Power Supply Mode
Independent power supply refers to the installation of dedicated security surveillance power sources in front of each camera. Each security surveillance power source supplies power to a single camera.
Centralized Power Supply Mode
In the centralized power supply mode, a 12V centralized power source is connected to a 220V electrical source, and then 2*1.0 red-black power cables are used to connect it to the cameras. The power supply should not exceed 100 meters at 12V. A single power cable connector is added, connecting the single power cable connector to the surveillance camera power connector. The centralized power supply mode involves using a 12V switching power source at the monitoring room or at an intermediate point to supply power to the front-end devices collectively. The most significant difference from the independent power supply mode is that a single power source can supply power to multiple cameras. When selecting dedicated outdoor security surveillance power sources, it's crucial to pay attention to their protective performance.
POE Power Supply
POE (Power over Ethernet) power supply is available in four main ways:
1. Both Switch and End Device Support POE: In this method, a POE switch connects directly to POE-supported wireless access points and network cameras through Ethernet cables. Ensure that the POE switch and devices are standard POE compliant and use high-quality Ethernet cables to prevent power and booting issues.
2. Switch Supports POE, End Device Does Not: In this scenario, a POE switch connects to a POE splitter, which separates power from data signals. The splitter has both power output and data signal output, which are connected to non-POE end devices.
3. Switch Does Not Support POE, End Device Supports POE: In this approach, a POE power source connects to the switch and provides power to the end device.
4. Neither Switch nor End Device Support POE: This method involves connecting a POE power source, followed by a POE splitter, and then transmitting power to the end device. Both method three and method four are suitable for retrofitting traditional networks where the existing switch does not support POE, but there's a desire to benefit from POE advantages.
