The new Samsung Techwin SRM-872 mobile network video recorder has been engineered to withstand the rigorous conditions experienced on buses, trams, trains and trucks.
Developed in response to increasing demand from the transport sector for robust IP network based solutions, the SRM-872 network video recorder, working in conjunction with two Samsung Techwin camera models which have also been specifically designed for the transport sector, offers a highly effective ‘mobile’ ONVIF compliant video surveillance monitoring and recording solution.
The SRM-872 NVR enables safety and security personnel to review latency free, high definition images of fast moving objects when an emergency or incident needs to be investigated. It achieves this by recording the images captured by 2 megapixel cameras at 60 frames per second through a recording bandwidth of 64Mbts, which ensures image edges are kept sharp and clear, and it can do so simultaneously across all of its eight channels.
Built-in GPS allows for location data to be recorded and whilst a hot-swappable 2.5” HDD can easily be removed for the purposes of backing-up video evidence, the SRM-872 also supports 3G/WiFi modules for “on the move” video retrieval. The compact size of the SRM-872 provides the option to conveniently locate it on or below the vehicle’s console and a built-in PoE switch minimises installation time.
With a built-in heater for low temperature (-25ºC) environments the SRM-872 has been approved for use by the European Railway industry and has been certificated conformant to the EN-50121-3-2, EN-50121-4, EN-50155, EN-61373 and EN-609050-1 standards.
Mobile camera options
Both the Samsung Techwin SNF-7010VM and SNV-6012M mobile cameras offer an enhanced Digital Image Stabilization (DIS) feature which negates the effects of vibration. This can greatly reduce the rolling shutter effects such as image wobbling or skew that can be seen in high quality images. They are also both equipped with a rugged M12 connector that is able to withstand vibration and harsh weather environments.
The SNF-7010VM 360-degree 3 megapixel (1080P) camera provides users with the option of selecting from a number of display options including 360-degree fisheye, single and double panorama, quad, rectangle or a user selectable region. Vandal resistant to IK10, the SNF-7010VM also features four polygonal motion detection zones and a digital PTZ, as well as Progressive Scan technology to provide sharp edges on moving subjects and vehicles.
The SNV-6012M 2MP Full HD mobile flat network camera can capture high quality colour images when the lighting level is as low as 0.03 lux and has an ultra fast frame rate of 60fps at 1080p. The enhanced Wide Dynamic Range built into the SNV-6012M’s WiseNetIII DSP chipset, with performance greater than 120dB, can accurately produce images in scenes that simultaneously contain very bright and very dark areas. It also offers a Defog feature which can be used to help improve the clarity of images captured in poor environmental conditions such as rain, smoke or fog.
Both the SNV-6012M and SNF-7010VM meets the EN50121 standard which covers electromagnetic emissions in railway environments whilst both cameras are weatherproof to IP66 and comply with the EN50155 standard.
