GPS Camera Detection

i have just bought a s5-r snooper laser detector.?

it picks up most speed camera’s, but when i went past a laser van nothing happened wonder how this is. its meant to pick them up, does the operator have to switch on the the laser beam, can anyone explain how they work or maybe he was asleep, or at his tea,

The s5-r has a reputation for not being terribly good, I’m afraid. However, the camera operator only triggers it when he’s decided to check a particular vehicle, he may not have been actually doing that at the time. It’s not an "always on" thing.

Is there a speed camera detector which detects mobile detector vans?

Not legally!, as the use a device that detects cameras is illegal.

As camera vans usually have reflective red and yellow signs on them and are so obvious by having the rear windows open, not to mention the fact that usually drivers travelling in the opposite direction flash their lights at you. You should really see them long before you get caught.

But then if you weren’t speeding in the first place you wouldn’t need to ask.

can radar detector such as beltronics 940 detect speed cameras?

It depends on the type of photo trap. Photo traps can be designed with a radar gun or a laser gun. It may also incorporate pneumatic trip lines or light sensors across the highway. If radar or laser is incorporated into the Photo Speed Trap, the radar gun or laser gun is pointed across the highway, typically at a shallow angle of 23 – 30 degrees. If the speed detected is above a pre-set speed, the radar or laser gun triggers the photo camera to flash. Depending on the speed of the vehicle, the camera is commanded to flash at a specific point in time to ensure the vehicle license plate is in the center frame. That digital picture image can be stored on hard drive on remote, unmanned speed traps, and picked up weekly by a technician. It can be sent immediately to a laptop, operated by an officer in the vehicle. It can be instantly emailed from a remote speed trap to a local computer processing center. In either case, once a computer operator has the electronic image, they can process it using a variety of computer programs.

The key here is that a good radar detector can detect this type of forward operating photo speed trap, and it may give you enough time to slow down. In a typical highway encounter, one may be driving 75MPH (110 feet per second), thus one may have 1-2 seconds to slow down, after you recognize the trap, if you recognize the speed trap. If you do not react fast enough, the camera is triggered and your license plate, and possibly your physical image is taken, stored sand sent for processing.

Long story short: Your Bel 940 will probably alert to many or most photo traps.

if a policeman claims you were going over the speed limit and its his word vs yours will it stand up in court?

A friends daughter (honest ..not me!) was pulled over and told she was doing 55 in a 30 zone when she maintains she wasnt even nearly doing that. He tried to bully her into taking a 3pt / £60 quick fine. she refused and asked to be tried by the court. she never admitted blame and refused to surrender her license. how does she stand in court? the police man had no cameras or laser eqpt.

He doesn’t need a camera or a laser, but he does need some form of corroboration, he will have had some form of device in the car, like a ‘Provida’ in which case you friend is bang to rights!

do blaupunkt gps radio cd systems give speed camera loations?

No unfortunately, there is no product available to support the indication of "points of interests" on the Blaupunkt systems, especially if you bought the earlier model which only showed arrows and no map. The latest Tom Tom and Garmin have built in point of interest handlers which can indicate proximity to the cameras (as gps locations) but its not developed yet on the blaupunkt. It’s a shame really
Maybe suggest getting a road angel or snooper as they not only have the same GPS pick up as the sat nav (so accuracy is good) but on certain models they can also pick up mobile cameras as well! which NONE of the sat nav’s at present are able to do

Hope it helps

How do I get the speed I’m traveling from 2 sets of GPS coordinates?

I’m developing a GPS Windows Mobile application (personal for now, but I might make it public) and I wanted to find out (theory wise) how to get the speed I’m traveling when given 2 sets of coordinates. I would go out and capture 2 coordinates driving at a constant speed, but I was hoping there was a magic formula.

You probably need some BASIC trigonometric …..
(I can’t believe you know how to write computer program but not knowing this…..)

anyways….first, you need 2 points…assuming you measure those 2 points exactely 1 second apart.

assuming
Point one:
47.64753 degree North
122.38547 degree West

Point two:
47.64822 degree North
122.38585 degree West

you subtract each coord. point 1 and point 2 and you get
0.00069 degree
0.00038 degree
(make sure use absolute value!)

convert your degree to radian first and times the R then you will have distance.

0.00069 degree *3.141592654 / 180 = 1.20428E-05 radian

0.00038 degree *3.141592654 / 180 = 6.63225E-06 radian

Now….Times Radius of the earth of (6,371,000) meters on average

76.72449939 in the J direction (north and south)
42.25407213 in the I direction (east and west)

Now, you find the 3rd side of a right triangle
which is sequare root of 2 other side’s square

so square root of ( 76.72449939 ^2 + 42.25407213 ^2 )
=87.590 meters

so the car traveled 87.590 meters in 1 second
times that 3600 seconds = 315324.97 meters
or approx 315,325 km/hour
it shouldn’t be too hard to convert it to miles
(divide that number by 1.609344 )
you will get 195.93 miles per hour

now, 1 problem is that earth is actually a 3D surface.
so if your GPS get a 3D coordinate (even better) you may want to utilize that……
(You will calculate it base on X,Y, Z instead of just X and Y axis)
the only difference is the last part.
distance is square root of (side 1 ^2 + side 2 ^2 + side 3 ^2 )

Interesting question!
