I was using this widget on habpanel just have not gotten around to creating something for the new main UI yet.
The reason for this is I use telegram to send an off site copy of the events so they are safe if someone steals the NVR. Very easy to review them in real-time from a phone without opening ports ina firewall.
I also like pushover as it can display a moving gif without needing to unlock or touch your phone. At work it was great as you just have the phone pointed towards you.
No but some features do require it. What URL were you wanting to display? Snapshots and autofps mjpeg streams do not need ffmpeg if your camera can supply a snapshot.
The lowest impact on your system would be the autofps.mjpeg since your cameras have motion detection in them. The ipcamera.mjpeg should also work if you setup the camera as per the docs and won’t need ffmpeg either. Just give them a try to see what U prefer.
