Site Number is optional now. From Videoguard it will be provided to the integrator. The integrator need to put the site number and send to the web service.
If WCF SERVICE is not reachable OR offline means at that time need to save the alarm locally and send that to videoguard when the service is reachable from the device. If NVR side is full you can overwrite in FIFO manner.
For example only we have shown the invalid MAC address. The other failure reason will be sent to you as string. When the log is failed to receive you need to rectify the problem & need to resend the alarm to videoguard.
Every day at one time need to sync the time from Videoguard once.
Whenever the VMS/ Recorder connecting to the videoguard at that time need to send the information one time only. If the VMS/ Recorder disconnect from the videoguard at the time of reconnecting need to send the recorder information.
