Looks nice, decent picture quality even when dark. Good quality power supply, with fuse and good separation between mains and output, so it should be safe. However, the outdoor unit wouldn't open a standard electromagnetic lock, because for some reason there was a 120 ohm resistor in series with the lock output, limiting the current. I had to open the outdoor unit and replace that resistor with a link to get it to work. It's a very weird design decision (maybe it was meant as a crude short circuit protection or a way to reduce interference from the lock's coil).
