Active vs Shutdown cameras?
 16 years
|
I've got a general question - what's a good way to tell Active Cameras, as opposed to Shut-Down cameras? I believe that around Phoenix, AZ many of the cities post camera locations on their websites, but that doesn't seem to be true in California.
Specifically, I'm trying to figure a camera in Roseville, CA. I've seen a news article from Oct 2007 which says Roseville shut-down all of their cameras, and then another camera from December (which I think is 2007 as well), saying they re-activated them. Not really sure which is the case! The cameras are physically still there.
Obviously, I'll treat them as if they're active, but it'd be really sweet if anyone knew a reliable method to get the info, so that the POI File can be as accurate as possible?

Since they don't post them on their site, I guess the best way is to watch the area at night for a few minutes. Around here, all it takes is 15 minutes to see that flash go off

Haha, hadn't thought of that
Haha, hadn't thought of that way - I like it!
Dont bet on it.
Some cameras use infrared rather than visible flashes. You won't see these.
They could probably be checked using a video camera as the CCD in the cameras does see infrared and visible light.
I wouldn't bet $100 on it though, which is what you are doing. You'll really hate youself for losing that bet.
Assume if you can see a camera it works.
Infrared doesn't flash visible light
After doing a google search on your city (Roseville, CA)I found this:

I would have to proceed as if the POI file is accurate, don't count on actually seeing a flash. Some systems use visible light and other do not.
Call your elected representative (council person, Mayor) and ask them straight up if they are on or off.
Seems to me that since 98 percent of the camera systems are owned by private contractors, If I owned the equipment and a city shut it down, I would pull the expensive equipment down and move it to another city. Now thats just my thought.

Didn't know
Hey, thanks for the extra info.. Had no clue that they used IR instead of visible flashes for some cameras -- good info to have!
Cameras
Folks
i build traffic signal intersections. A lot of intersections have cameras that are there to detect the motion of traffic.
If you see the cameras facing the oncomming traffic they are most likely for detection of motion to change the lights

I hope that they all go to IR soon. IR cameras are more readily defeated. See http://hackedgadgets.com/2008/02/21/ir-leds-used-to-defeat-s...

Pretty Cool Idea....But
This is neat, I had not thought of it.
This would have to be on 100% of the time to be effective against every red light camera. If it distorts your tag plate on the redlight camera by whiting it out, it will also distort it on the cameras found in patrol cars with the same white out.
Not sure how the law actually reads on obscured tag plates, but if an officer spotted you with using the camera in his patrol car you at least are guaranteed a trip to see the judge to explain yourself and get a ruling. Good luck on that one.
Once the local enforcement gets a look at what your tag looks like on camera, they may go back and find all the whited out tags.
I agree, very interesting
I agree, very interesting concept. You're right though - if caught, you'll have a lot of explaining to do! Not quite worth it in my book, I'd rather just not speed through a camera intersection.
