Irisys (InfraRed Integrated Systems), a Northampton-based company, has launched the IRI 4011 and IRI 4041 handheld thermal imagers. Specifically designed for police and security teams, the imagers provide affordable thermal imaging performance in a compact easy-to-use package. Featuring a 160 x 120 pixel silicon microbolometer sensor, the imagers deliver clear images in total darkness, detecting people at over 150m for the 4011 model and 300m from the 4041.
The 4011 features a clear 3½-inch display, with user friendly menus for camera control specifically optimised for police requirements. An eyeshade provides discrete viewing for covert operations and images can be easily stored using the standard removable SD memory card. Selectable colour pallets include colour and 'white hot' and 'black hot' display, and a hot-spot tracker aids automatic detection of a person in the field of view. The freeze frame feature helps in searching restricted access areas.
For detection of cannabis factories, a calibrated temperature display can be selected providing remote monitoring of roof, window and vent temperatures. Two cursors allow clear comparison of temperatures between adjacent buildings.
The Irisys 4000 series PC software allows stored images to be uploaded to a computer and exported as standard bitmap pictures to office applications for incident reports.
The 4011's integral rechargeable battery provides six hours of continuous operation. Also included within the imager's rugged carry case are mains and car chargers, eyeshade, and the PC software with SD card reader.
