Is there any software I can use to save the “last 2 min” of a file every time the alarm starts?

Question

I have a PTZ security camera connected to the Internet. I need to capture the action every 2 minutes. These are the “last 2 min” that are overwritten continuously. I have a connection to alarm signaland I'm looking for a software that can save the “last 2 min” of a file every time it gets an alarm signal so I will be able to capture video from 2 min before alarm occurred. Help me, please!

Answer 1

PTZ security cams have their own software that can perform this task. In fact, the software is configured to display and record a certain timeframe even if the alarm goes on/off. There is a certain amount of time that is recorded by the camera just in case something goes wrong or the alarm goes on. Use the software that came with the cam as this is the only compatible program for the job.
