I have a 1st gen Indoor cam coming up on 5 years since purchase. A few years ago I started using it to monitor the driveway through a window so turned off the IR nightvision. We moved house earlier in the year so it's not been used for about 6 months, but I've just had it in use whilst we were on holiday and noticed that there was no footage overnight. Checking the settings I realised that the IR was still toggled off, so I toggled it back on and... nothing. Remotely rebooted the cam but this did nothing either, and since being back I've reset the device and this hasn't helped either.

Anything else I can look at, or given the age of the camera do I just need to replace it if I want nightvision footage?
