I don't know why this has to be so difficult, but it is. I am trying to find a DVR that will record when it receives an Alarm input (from PIR). I want to record for 2 to 5 minutes. I would like to record for 30sec or so pre-alarm. It would be nice if each Alarm input were associated only with that specific camera/channel, but I can live if all channels record simultaneously on any Alarm input tripping. On playback, I only want to playback alarm activated events and, ideally, would like simultaneous playback of all cameras attached to DVR on one screen. I need support for iOS and Android PLUS a non-ActiveX app for a Windows PC for remote viewing. I also want an email with snapshots on any Alarm.
Can anyone suggest some DVRs that I can look at. I have spent hours trolling the internet but this level of detail is never available for any of the DVRs.
Thanks for your help
