Mobotix offers dual lens thermals

Mobotix brings the dual lenses concept to thermal cameras. The compact S15D FlexMount is a universally deployable, easily concealable video system with a highly detailed resolution of up to 10 megapixels. The fully weatherproof IP camera has two miniature sensor modules, which are each connected to the camera housing with a two-metre cable. Thanks to the hemispheric dual lens, two separate rooms can be secured simultaneously without any blind spots.

The new thermal sensor modules measure the thermal radiation of objects, so that they can function in absolute darkness. Together with the new MxActivitySensor, they can reliably detect motion in images at night. Only changes in position trigger a signal; objects moving on the spot do not trigger a signal. The thermal sensor modules also have an advantage during the day since they can detect moving objects in shadows, semi-darkness, smoke, or behind bushes.

The thermal sensor modules are also designed for connection in the weatherproof aluminium housing on the S15D camera, for example, for customer-specific special installations. Mobotix thermal cameras are designed for around-the-clock operation in industrial conditions. Just like for the M15D-Thermal, there are different focal lengths available: L43 (wide-angle 45°), L65 (tele 25°) and L135 (tele 17°).

Unlike cameras with 5 MP image sensors, one of the decisive quality criteria for a thermal camera is not the image resolution, measured in pixels, but rather the camera’s ability to capture the slightest differences in temperature and to produce an image that displays these differences in colours. The sensitivity of a thermal sensor is measured in millikelvin by the NETD, or Noise Equivalent Temperature Difference. Mobotix thermal cameras offer a sensor value of 50 mK, which places them in the top range of cameras currently available for general use.

Without extra cooling, heating, or PTZ motors, the S15D, even with two thermal sensor modules, requires only about 8 watts of power and can therefore be powered cost-efficiently by just one PoE cable in outdoor temperatures from -30°C to 60°C.

The modular design of the M15D system platform ensures maximum flexibility for the Mobotix thermographic camera. The M15D-Thermal comes standard with a thermal image sensor and a dummy module (to remain weatherproof to IP66).
