I'm hoping I can find some resolution before proceding to a hardware change.
This is for an 8-camera system at an entry/exit gate and guard house in a private community.
The issue I'm running into is at night when the motion detect recordings are triggered too late (car tail lights etc.) and I only get partial footage of vehicles, license plates and occasionally people. This should be a non issue as in almost all cases I set the pre-record value to 30 seconds, but the pre-record does not seem to occur regardless of what I do.
This system is a combination of a Performance IP NVR and an HQA DVR (LPC cameras) with 3rd party IP cameras and 2 analog Dahua LPC cameras. The video is fine. Sensitivity and threshold settings for motion recordings have been a bear to tune. But mainly, the set up will never work if prerecord is not working as moving vehicle lights trigger the recording too late to get a complete footage of some license plates and cars.
Any suggestion and ideas on how to get this to work properly would be appreciated. Since the pre-record is set at the NVR/DVR level, I'm not sure if non-Dahua/Honeywell cameras would have an impact on this issue.
Thanks in advance for the help.
