Dahua DHI-VTNS2003B-2-A - 2-Wire Switch for Video Intercom System
The Dahua DHI-VTNS2003B-2-A is a 2-wire switch for a Dahua video intercom system. It forms part of a video door entry system, linking the indoor monitors and door stations over 2-wire. Dahua describes the VTNS2003B-2 as a 2-wire switch that supports 10-level cascade through the 2-wire port, connects up to 20 indoor monitors and 2 door stations, and can also connect through an RJ45 port. Dahua's datasheet and UK product page are for the VTNS2003B-2; this listing carries the -A suffix, which Dahua's datasheet does not explain, so the specification below is Dahua's VTNS2003B-2 specification. It is a 2-wire intercom switch with a DC 48 V input, not a PoE switch.
Also listed as VTNS2003B-2-A.
