PLEASE NOTE: This POC DVR does not support BALUNS

The SPRO B4 range of DVRs are POC recorders. This means they are able to power POC compatible cameras through the same BNC cable that carries the video signal. This means a lot less time is spent cabling the unit, a lot less cables being run around a property also means a neater install for your customer.

As with other SPRO recorders, the B4 range also supports 4K video over co-ax, audio over co-ax, alarm over co-ax, PTZ control over co-ax and IP audio over CAT5e.
