Cooled Thermal

Cooled thermal imaging uses an integrated cryogenic cooler, which chills the thermal image core to temperatures as low as -196°C (-321°F) to increase the sensitivity and accuracy of the thermal image.

Detection Rating (DRI)

Based on the DRI standards, detection means that you will be able to see the target, however it will be little more than a speck. There is a 50% chance that the target will be visible on at least two pixels, and there is a good chance that it is something of suspicion.

ONVIF

ONVIF is a standard for IP video surveillance devices. While it usually works well for basic video integrations, ONVIF is not ideal for handling PTZ commands of EO/IR systems and does not allow for many advanced commands such as switching thermal palettes, enabling gyro stabilization, enabling NIR/Fog Filters, etc.  

Sensor Sizes Explained

Let’s face it, digital camera sensors are measured in ridiculous ways. If you’re trying to make sense of what dimension a 1/2.8" sensor size is referring to, or if you’re wondering how thermal imaging sensor measurements are different, you’ve come to the right place.
