Speed Cameras (and RADAR)

 

So if we are now at the point where cameras are used to detect speed then (at the risk of asking a rhetorical question,) why do police cars still use RADAR instead of cameras? (By rhetorical I meant - Could it be so that companies can sell RADAR detectors??? Or instead, are these too not camearas but instead RADAR?..)

Speed Cameras

As far as I know, speed cameras work by either using radar or timing you across a known distance to get your speed. Police can also time you across a known distance (using the white lines across the interstate) or use laser. For a mobile police unit, radar and/or laser would seem ideal since they are self contained and don't need a measured distance to function.

Speed Cameras

Speed cameras use the photos to capture you speeding. They use the laser, radar, LiDar or Dopler to actually track your speed.

Cops use these also, but can't use the cameras when moving. I agree that they should do this at stationary speed traps for safety alone.

Because I noticed you posted the same one word post today twice, then looked at your history and you have posted a total of 5 times (four of them today) for a grand total of 5 whole words. To summarize your posts in their entirety: Nice, Nice, What, What, & Thanks. ?????

Probably just wants the redlight file.

Lets get this thread back on track...

When I lived in BC, they had Vans equiped with photo radars. They would park them in any locations where they had a higher risk/occurence of accidents and/or speeding.

Not sure if they still use these but they were were quite effective at catching speeders even tought their location was openly advertised in teh media daily.

Photo "RADARs"?..

I guess I'm still wondering if the technology exists. Meaning the word "RADAR" stands for RAdio Detecting And Imaging"... So has technology advance to a point where there are speed measuring devices that don't use the "radio" transmissions?

Speed camera tickets

What speed would a speed camera issue a ticket. Would someone get ticketed at 5mph over the limit. Are they accurate? Do they mistake the car next to yours as speeding or vice versa, when they are measuring speed.
How would they send someone a ticket would it be mailed to that persons address in a different state?

I'm not sure if they set a

I'm not sure if they set a "speeding limit" on the speed limit - but it would be ironic. They just got these things here in New Orleans, and the send the ticket to your address by way of your license plate. I haven't gotten one yet, but I hear they are pretty accurate. The tickets don't go on your driving record, so it won't affect your insurance; it's listed as a civil offense. At least down here that's how they are doing it.

Hey, Grandad

You were almost right. From dictionary.com:

radar

1941, acronym (more or less) for radio detecting and ranging. The U.S. choice, it won out over British radiolocation. razz

Speed & Redlight Cameras in AZ

Whether or not a speed camera ticket goes on your insurance or not depends on the state in which you're ticketed. Here in Arizona they use speed cameras and redlight cameras and both tickets produced by these devices will result in points on your license and an increase in your insurance. The flip side is that the law states that you have to be served with the ticket in person. From what I hear, they may not bother with tickets to out of state plates.

The camera is not used to capture the speed, but only make a record of the offender.

Should be pretty accurate

As far as what speed I would guess it would be like a mobile RADAR gun. They have an alarm speed they can set. So the cop just sets it up and waits for the alarm to go off. And I would guess they would be as accurate as the handheld models if not more. I got a ticket in Arizona from one of the mobile ones from the middle of I-10. Don't know if it was just on the side of the road or in a van but I never saw it.

Thanks Plunder for correcting my post...My brian and fingers were obvously not connected.. (Haven't a clue what I was thinking.. The "I" in Imaging is obvously inconsistent with last "R" in RADAR.)

Laser, visual (camera), ultrasonic, etc.

Laser of course.

It would also be fairly simple to check distance traveled over time which could be done in a number of ways including using a camera to check the change in position of an object over a period of time.

How about ultrasonics or some other sort of sound wave echo technology?

It's also probably because they have more areas to cover. While there are stationary set at intersections, police can move about. I hate to say revenue generator but it seems with state budgets hitting crunches, they may be going to spots they never were before.

Revenue Generator

Redlight and speed cameras being a revenue generator is a huge topic here in AZ. The state has a budget shortfall and our illustrious governor stated that the State would increase the number of cameras on the interstate and other roads to "make the roads safer".

MA State Troopers don't even hide it!

Nothing to do with Cameras, but here in Massachusetts, the Massachusetts Turnpike Authority basically said flat out that to make up revenue shortfalls, they were going to increase the use of radar with State Police in order to catch more speeders to write more tickets to close the budget gap.

It ain't no fun to play the "quota" card on them only to have them pull a Tricky Dick Cheney and say ya, "So?"
