Crazy Purchase time.......
I have just added 53 IRISYS thermal people counting cameras to my collection. That's right......53 of them !
I believe I will be taking delivery of 50 IRC1004/1014 camera sensors and 3 of the latest higher resolution Gazelle Sensors, along with 3 of the computers that collect data from them all.
These are a form of low resolution thermal camera. They use a Germanium lens to focus the thermal scene onto the IRISYS manufactured 16x16 pixel pyroelectric detector FPA. This is the same array as used in the IRC1001' 1002 and 1011 thermal cameras. The camera can detect the presence, location and movement of people. The intelligence gathered is used for till line management and retail related customer profiling. They make great intruder sensors as well. Each sensor may be individually programmed with boundariy lines that trigger a count event or alarm. Kind of an invisible 'barrier' that the targets cross to cause an event. Several barriers may be set up and the sensors individually track multiple targets within their FOV before handing off to the next monitoring sensor, if appropriate. Clever stuff as the front end processing takes place in a compact unit the size of a smoke detector. Programming is via a plug in RS232 interface and some software that IRISYS sent me some time ago. The software permits viewing of the live thermal scene
The Gazelle sensor is a slightly higher resolution. I suspect it uses either a Redeye 6A 31x31 pixel array, or the later 47x47 pixel array.
Now to decide what to do with them all. That is a lot of dinky little Germanium lenses and thermal detector FPA's.
I just happen to own 50 Dewalt (IRISYS) visual thermometers (similar to Fluke VT02). They are without their detector array and lens. Hmmm a possible transplant project maybe ? We shall see
