I see an AE Model 13 in the background.

And this looks nice. And what would the cameras be used for? Like what would they do?

I mentioned what the cameras do in the description

No I mean't how are they used for detection and homeland security? What are they trying to capture?

Intelight has software installed in each signal that can wirelessly transmit the video images to a central traffic office or the police department...if that feature is enabled. This was a feature that Optisoft pioneered.

If detection is used on the cameras, a processor made by Intelight is installed in the traffic signal controller cabinet to detect vehicles approaching the intersection. They would work just like regular detection cameras operate, except in a smaller package installed inside the signal itself.

"Base model" Intelights are sold without cameras installed leaving nothing inside those little windows on the door.

Would a loop detector not be cheaper than the camera and associated controller for almost all applications? I get gate loops for under $30, excluding the loop, which work well for most driveways.

We had loop detectors before, but the cameras are easier to repair, to install...

the problems with inductance loops is they are often damaged when the road expands and contracts during the seasons. A loop is tuned using a loop amp in the cabinet. Each loop in the pavement runs on its own loop amp.

If the amplifier is set too low, it wont detect smaller vehicles, if its set too high it starts to interfere with other loops sending out false calls. To run the loop lines from cutting the pavement, installation, and the loop amps in the cabinet is around $1,500. Cheap, actually, compared to most other detection methods.

I operate video detection in my own collection so I know first hand how it operates. It is alot easier to work with. You just plug in the laptop with the software installed, set up the cameras and features, and download it to the video processor in the cabinet. You draw in zones using the software which are basically big square boxes that you want detection to be placed at. Then you match that zone to an output so the controller knows which output has a call. It does have its disadvantages though...like cameras getting mis-aimed. My video stuff is fairly old now so I got it cheap, but the newest equipment is around $8-10,000

Another company, called WaveTronix is developing radar traffic detection which is alot easier to work with than video. But it isn't cheap either.

I have seen those radar detectors on test here, they would probably be a lot cheaper than a loop installation wise, as they fit on top of the signal. I agree on the cutting of the road, but here there is not so big a temperature swing, and labour here is a lot cheaper than in the USA. A big user of loops is red light violation cameras, as they need to show in the inevitable court case a physical sensor to detect the car ( Lawyers ..........................*&^####@***&$%^) over the painted line.

Do you have any information or maybe catalogs or any small info about those sonic wave systems

We got a good number STILL IN USE in Baltimore City...There are also other types I found in the city but was not able to get pictures of them....yet......

Wavetronix radar is $10,000 a cabinet. Alot more expensive than loops.

Loop detection is the cheapest and the quickest to install. Its also one of the oldest and most common forms for traffic actuated intersections.

Gullwhiz--that is very old. I'm talking about modern radar equipment. Here are some specs on the Wavetronix equipment

I know...but I would kinda expect you to know old systems Old Systems are even more special because not many are seen now days! The one I just showed you seem to go right directly under a specific lane from what I have seen! By the way call me Jace

Alrighty Jace! I like to put names to people rather than screen names myself. I'm Nick. The one in your link doesnt ring a bell to me, which leaves me to believe it was designed by the city/county themselves.

Hello there Nick! I don't think so because those were also found in other places....not just the city....The other place I know is in Texas, I saw a pic, exact same design....it obviously is from the 1950s to 1960s since it had the EXACT same slipfitter you would find on older GE streetlight fixtures which made me think it is actually a GE...-plus the other guy said he's seen them in Chicagoland according to the comment in that pic linked.
