Working Parameter |
Specification details |
| Power Input |
8-36V |
1. The input voltage is +8V～+36V, if the voltage is lower than 8V or higher than 36V for a long time, the device will automatically shut down and enter the protection mode.
2. Pure step-down power supply, the system is divided into two power supplies (camera and system power supply are independent) |
| Output Voltage |
CAME_12V X 4 |
The total current is 5A, it is a 1A interface to the AHD camera. You can control the switch on and off the camera as needed for that camera power supply. This system can independently control the power of the camera and the monitor, which is convenient for turning off unnecessary cameras and displays after a delayed shutdown |
| 12V OUT |
The output voltage is 12V(+/-0.2V), The maximum current is 3A. |
| 5V OUT |
The output voltage is 5V(+/-0.2V), The maximum current is 1A. |
| Car Key (ACC) Signal |
≤6V |
The car key is off |
| |
≥7.5V |
The car key is on |
| Built-in UPS |
5x7F*2.7V |
1. Power on and charge, and it will be fully charged in 3 minutes. It still keeps the system working for 10s when the external power failure, also continues to complete data saving and shutdown.
2. To ensure that the device will not restart when the input power supply is instability.
3. Built-in UPS polymer battery is optional (1-3 hours), built-in interface and fixed position are standard |
