PTZ Preset Information Recorded By VMS?

Hi John!

Your question reflects exactly what I meant. Given that the camera can be facing different areas of interest (through the use of PTZ presets), one may be interested in reviewing the recorded video of a specific preset / area of interest only.

I am personally not aware either of any VMS that does that! That's why the question...

Ethan, I am assuming you mean create a rule to add a bookmark automatically anytime the camera moves to preset X?

In my experience, the VMS doesn't typically even control the PTZ except when it's being moved by the user or by other outside influence (alarm inputs, for example). Presets, patterns and tours are generally stored in the camera itself; the VMS might be programmed to initiate a preset, pattern or tour after a timeout, but otherwise, those things are usually self-contained.

Now if the presets are being triggered by alarm inputs, it should be possible to bookmark on those (assuming your VMS does live bookmarking). But if the PTZ is running its own internal pattern or tour, there would simply be no way for the VMS to know when the camera moves to a particular position.

Actually, now that I think about, Vigil does have an option to program a tour within the software, where it simply calls a preset, waits a pre-described period, calls the next preset, and so on... I suppose some others would do that as well. I don't think it would bookmark those though.

And just brainstorming some more here... Vigil does have a "POS" function that can receive and log text data on a serial port... if the camera was able to send back the appropriate information over its control line (assuming you've wired for TX on the camera, RX on the DVR), that could be logged in the POS section, which is designed to synchronize POS events to video... SORT OF a bookmark function.
