Q. Are security camera recordings archived?
Can people go back and look at security footage to the exact moment two years after the event, for example?


Answer
Yes, but usually only 24 hours.

If they Had the tape/disk/drive, Sure. It is all time/date stamped.

Two years, usually not. It is often held only 24 hours. Varies by individual policty, but generally one day.Two years would be a Pile of disks or tape. It is usually reviewed daily, then only kept if a report had been made of a robbery or something on that shift. If not, it is recorded over. So, if there was a crime committed, it would be held, and, subpoenaed. Then it would be in police evicence, not the place it was recorded in. It could then, in that case, be held for a couple years, depends. After the case, it would be returned and taped over.

EDIT: Most cameras now record to disk or flash drive. They can review yesterday's while it is recording today's.They don't hold a lot of video tape, like in the '70's. They record every 5 seconds or so to save media, too. Video tape didn't do that.

What was wrong with my security cameras?

Q. So today I came home to a bit of a surprise... I live in a quit neighborhood so I never expected this. Anyway, I find my street blocked off, and when Arriving to my house, found the telephone pole in my neighbor from three doors down's yard snapped in half, and an SUV flipped in their yard.

Then I remembered I have security camera's that point almost directly where it happened. My security camera's record when they detect motion, but when reviewing the video's, it never tapped the accident? The last video before the accident was the mail carrier going up the street, then the next video was 10min later, which showed the car flipped upside down and the street full of cops, firetrucks, etc. But it missed the actual accident... how? The power surprisingly never went out, All my clocks were still set, computers still on, etc. How did it not record it? What's wrong with it?


Answer
Motion detection through video is not a perfect science. The first thing I would do is make sure that all the areas are "armed" by that camera. You may have part of the scene "unarmed". The next thing I would do is put the sensitivity up by one number, making it somewhat "hotter". Experiment with your software settings. See the system manual if you don't know how to change the settings.
