Motion detection pseudo-camera / thermal imaging

[roach 0]

Software motion detection using visual light cameras is prone to false positives. An actual pyroelectric electronic motion sensor is much more reliable. However, on a low-cost pc security system with video capture cards, those with the 4 bnc ports for connecting cameras, motion detection is done via the software.

 

If someone made a pyroelectric like electronic motion sensor that could be connected as a camera to one of the bnc ports, but produce colored images in the infrared band, not for visual recognition of objects by people, but for presenting high-contrast infrared to the software, motion detection could be highly improved. The infrared patters could be represented by high contrast colors from a 16 or 256 color palette. (Think Predator, the movie, how the alien seen things with his visor or whatever it was.) It's called FLIR, or Forward Looking InfraRed.

 

Consider a large room with two camera type devices monitoring the area. One being a typical CCTV camera to provide a visual image and the second a pseudo camera that only sees infrared and generates high contrast patters to the software. Motion detection would only need to be enabled on the motion sensor camera that could trigger recording on the other via most low-end software.

 

I've been searching for a pyroelectric style motion sensor that has a bnc connector to interface with typical CCTV cards. The closest thing I have come up with so far is this X10 product:

(lame forum function restricted my providing the link.)

 

However, it is actually a dual device and it has a multiple connectors. I don't believe it will perform the task by interfacing with an inexpensive bnc connector CCTV card.

 

Any thoughts?

I agree with you that motion sensors can nicely compliment video motion detection. Some Mobotix cameras have PiR sensors built in and I have found it very useful.

 

Could you not hookup a PiR sensor to an alarm interface so that could trigger recording? I'm not familiar with PC based cards, only the appliances, most of which do have alarm inputs. Does the recording software allow for other PC based triggers such as serial or USB input?
