The Mobotix M73 has been developed with the goal of being the best and most innovative IoT network camera. It expands the DNA of Mobotix while preserving the company's traditions. Completely new and unique, it is intelligent, flexible, and versatile. The M73 is the first Mobotix M-camera with three modules. With the intelligent plug-in app concept, applications such as license plate recognition, people counting, facial recognition, or fire early detection can be easily activated. It features a platform with the most flexible codec support: H.264, H.265, MxPEG+, and MJPEG+. It is ONVIF Profile S and T compliant for the highest interoperability. Increased modularity is achieved through the flexible use of a combination of up to three sensor or function modules. The camera includes a triple shutter WDR with a range of 120 dB and an easy plug quick-mount system. It is ready for use in all environmental conditions, operating from -40 to 65 °C, with an IP66 rating and IK07 impact protection. Environmental sensors can be added via the MultiSense function module (from 2020). Mounting options include wall and mast (with accessories). The maximum image size is 4K UHD 3840x2160, 16:9.
