The CHeKT Bridge alarm device uses ONVIF Profile-S protocols, RTSP, or HTTP streams to communicate with IP Cameras.
This can be used to alert monitoring center operators of system alerts to show operators what caused the alarm to occur through video or snapshots, where the alarm occurred, and other details pertaining to the event.
To learn more about the CHeKT Bridge, check out this video:
Works with DW Spectrum IPVMS Webinar Recording: CHeKT (5/12/20)
Note: It may be recommended to reduce the recording performance of the system by at least half (≤40 Mbps) to drop the CPU use to 50% (approx.).
This does not resolve the limited number of maximum connections (16-channels) with the VMAX IP Plus.
Main Stream: rtsp://<NVR ipaddress>:<rtsp port>/main/ch<channel from NVR>
Sub-Stream: rtsp://<NVR ipaddress>:<rtsp port>/sub/ch<channel from NVR>
Note: Default RTSP Port for VMAX IP Plus is Port 554.
