#Power supply of the video recorder
Power supply of the video recorder.
The video surveillance system belongs to the group of consumers of electricity of the first reliability category.
The issue of power backup of the video recorder is decided every time when designing such a system.
And often the designer makes a mistake — he selects the nominal current of the power supply based on the passport data of the recorder.
But: the passport data of the video recorder indicate the standard current value, without taking into account the acceleration of the hard drives, and the maximum value is often not indicated, «as unnecessary».
What to do?
The easiest way is to look at the nominal current of the adapter to the video recorder, it is indicated on the case. This is the minimum that you should expect.
