It's always something:
Powwer issue
Cables that are all around
Cameras on tripods, which are constantly bumped by someone
Cameras too high, too deep, or crooked
At night everything is too dark, because too weak IR spotlights are installed on the ground (!).
Today sound, tomorrow no sound, overmorning hum
If sound, thenm terrible quality
Image breaks live and replay
Unsharp pictures
Short: Cheap, broken technology, installed by residents who need to earn their money as actors on voyeur sites.
It's just enough now!
