Model introduction

256 06812X H WR
Resolution Lens Focal Length Gain Temperature




04010X: 4.0 mm F1.0

09010X: 9.0 mm F1.0


H: High-quality

S: High-quality/ Wide range (configurable)


WR: Industrial



HR: High response

NOTE 1. High-quality mode refers to the high-gain mode, where the module response rate is high, and the imaging quality is good, but the temperature measurement range is narrow; Wide-range mode refers to the original low gain mode, where the module response rate is low, and the imaging quality is decreased, but the temperature measurement range is wide.

NOTE 2. The default factory is the fixed focus version (fixed headless set screw), if you loosen the headless set screw, it will switch to the manual focus version.

NOTE 1. The above detection distance, recognition distance and identification distance are estimated according to Johnson’s Criteria, taking pedestrians (1.8×0.5×0.3 m) as the target. The temperature measuring distance is estimated by a non-point source blackbody with a diameter of 0.15 m.

NOTE 2. The temperature correction here refers to the distance correction tables, which can be provided by Infisense. Customers can correct the accuracy of temperature measurement targets at a longer distance by other distance correction methods.
