Hotel monitoring equipment

Hard disk video recorder 16,

Monitor,

A computer hard disk (installed in a hard disk video recorder, a camera usually needs 3G for 24 hours, depending on how much hard disk you need),

Samsung and Sony's cameras are particularly expensive, so they can be made in China, and the effect is good. I used it.

Installation:

It is ok to install a 30m camera on each floor, which can illuminate the staircase corridor, and it can be 6MM or 3.6MM (depending on the corridor length).

The first floor can be installed as you say, one at the gate. It is recommended to shoot those people in and out with a 6MM lens, and everything else is fine.
