My video glasses advertise that they will record for 90 minutes on a full battery. I don't really trust that, but would feel safe at an hour. The longest recording I've had with them is about 15 minutes - when I was about 20th in line at a car wash.....
I think the biggest issue with them for apartments, etc. is that they are worn on the head (duh). We don't realize how frequently and dramatically our heads swivel with normal interactions. This movement makes a real mess of video work. It took a bit of practice just to acclimate to some unnatural movements for shorter visits that I do with them - such as valet parking - where the videos are typically under four minutes. Doing that for a 30-minute visit would be rough.
That said: They do have a much higher resolution than my PV-500.
Hard work builds character and homework is good for your soul.
