Can the indoor surveillance camera still work when the power is off?

1, conventional large-scale monitoring equipment requires ups power supply. After the external power supply is cut off, the standby power supply is started and the monitoring works as usual. The surveillance video of the road used by public security and the surveillance video of large enterprises all belong to this category.

2. In order to save money, most owners don't have a backup ups power supply for such small surveillance videos as the checkout counter and the door of the store. If there is a power failure, the monitoring will not work.

Installation process

1. The rated voltage of the wire for monitoring camera should be greater than the working voltage of the line; The insulation of the conductor shall conform to the installation mode of the line and the environmental conditions for laying. The cross-sectional area of the conductor should meet the requirements of power supply and mechanical strength.

2. When wiring, try to avoid wires with connectors. In addition to using the connector, the connector of the camera must be crimped or welded, and the wire connection and branch should not be subjected to mechanical force. Under no circumstances can the wires passing through the pipeline have connectors. If necessary, put the connector on the probe terminal of the junction box as far as possible.

3. Wiring should be installed horizontally or vertically in the building. Wiring should be protected by casing (plastic pipe or iron pipe, which should be selected according to the technical requirements of indoor piping), and metal hose can be used for ceiling wiring, but it needs to be fixed firmly and beautifully.

4. The signal line cannot be parallel to the high-power power line, let alone run in the same tube. If you want to walk parallel lines due to environmental restrictions, stay away from more than 50cm.

5. The AC power supply of the alarm control box should be wired separately, and the camera should not be threaded with the signal line and the low-voltage DC power line in the same tube. The installation of AC power cord shall conform to the electrical installation standard.

6. The wiring from the alarm control box to the ceiling requires that the alarm control box be placed in the wall or protected with iron pipes to improve the anti-sabotage performance of the anti-theft system.

7. There are two kinds of conduit wiring: open wiring and dark wiring. The exposed piping of the camera should be horizontal and vertical, neat and beautiful.
