4-channel H.264/MJPEG streaming video recorders for mobile surveillance
.jpg)


The MxNVR-MO4 is a streaming DVR (digital video recorder), which can transmit and record H.264 or MJPEG video streams simultaneously. With a rugged design that is compliant with the essential sections of EN 50155, covering power characteristics, EMC, vibration, shock and temperature (T model, TX temperature level), the MxNVR-MO4 especially excels in rolling stock IP video surveillance applications. Moreover, the MxNVR-MO4 has passed EN 61373 standard anti-vibration testing with a 2.5 inch hard disk (purchased separately), delivering highly reliable storage performance for rolling stock applications. The MxNVR-MO4 can be triggered to record by system boot, by event, by schedule, or by external commands, such as CGI or SNMP. The embedded DynaStream™ function increases the network transmission efficiency by dynamically adjusting the video frame rate. To prevent unauthorized access, advanced 802.1X authentication is available to provide high network security. The MxNVR-MO4 also supports the ONVIF standard to easily integrate and interoperate with third party systems and software.
