Thermal surveillance cameras

Optics + thermal imager

— cameras that combine classic optics and a thermal imager — in the form of two separate "eyes" located side by side. Usually, they are able to broadcast not only two separate video streams, but also one signal that combines data from both lenses.

Cameras of this type combine the advantages of optical and thermal models and mutually compensate for the disadvantages; it is interesting that they are much cheaper than classic thermal imaging devices. This is due to the fact that the thermal imager in this case is not intended to build a full-fledged image, but only as an accessory that supplements the data from classical optics — which means that the “thermal” part of the camera does not need advanced characteristics. So, due to the combination of affordability and practicality, such hybrid cameras are quite popular nowadays — much more popular than specialized thermal models.
