FAQ
Q: Which model of VTO (Outdoor Station) can work stand-alone and make a call notification to DMSS when call button is pressed?
A: DHI-VTO22202F-P, VTO2000A-S, VTO-2000A-2-S, VTO2111D-WP-S, VTO2000A, VTO2000A-2
Q: Can Apartment outdoor station (VTO1210C-X and VTO1210C-X-S and DHI-VTO4202F) work with DMSS App?
A: Yes, but it requires License for firmware customization. Please reach out to your local Sales Rep or Technical Consultant.
Q: How do I access device config page in VTH (indoor monitor) device?
A: From the homepage, press and hold Settings button for 6 seconds.
Q: What the difference between Transmission 1 and Transmission 2 on the network settings?
A: Mode 1: Multicast (multicast).
The default is mode 1. Using multicast in a multicast network environment, the effect is best at this time
Mode 2: Unicast (TCP),
If the router does not support multicast, the group call will have a black screen on VTH, then you can switch to unicast mode. In addition, if the network is particularly poor, you can also use this mode, because TCP has a retransmission mechanism to avoid frame loss.
