We're looking for some software that will monitor the health of 6 NVRs and 13 IP cameras connected to a LAN. Most likely the NVRs will be running Exacq on Windows 7, but we could use Ubuntu 10.04 or 12.04 instead if needed.
We had planned to use Exacq's ESM (Enterprise System Monitor) running on custom-build NVR hardware for this task, but the Exacq RSM is refusing to allow the sale of Enterprise VMS licenses because he "needs the hardware sale on this one" (referring to selling 6 Exacq LC series boxes).
If we can find a good free or paid alternative NVR/IP cam health monitoring software (and ultimately an alternative VMS after this project) then we can ditch Exacq Enterprise and use Pro. We don't need anything crazy fancy, just something that will monitor 19 IP devices and send an alert of some sort if a device is not responding to a ping for example. It's a requirement of the tender for this project.
If anyone has any advice it would be hugely appreciated.
