I am looking for a online script to verify the online status of my camera systems.
The NVR sends a status e-mail every 30 minutes. Our existing script uses this mail to resolve the NVR's IP adress and updates the ddns info when needed.
I would like to upgrade this script to
- monitor if the system is still sending mails. If no mail recieved in 12h, this shows up in the status page
- check the open ports with telnet every 12h, if ports not open -> report on status page
- Daily report is mailed with NVR's who failed
- Every mail / online check,.. is logged
