The new Samsung Techwin SRM-872 mobile network video recorder has been engineered to withstand conditions on buses, trams, trains and trucks. Developed in response to transport sector demand for IP network based products, the SRM-872 network video recorder, working with two Samsung Techwin camera models which have also been designed for transport use, offers ‘mobile’ ONVIF-compliant video monitoring and recording.
According to the company the SRM-872 NVR offers 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, 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-inch HDD can be removed for backing up video. 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 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 temperatures 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 SNF-7010VM and SNV-6012M, pictured, 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.
The SNF-7010VM 360-degree 3 megapixel (1080P) camera provides 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 quality colour images when the lighting level is as low as 0.03 lux and has a 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 produce images in scenes that simultaneously contain very bright and very dark areas, the makers add. It also offers a Defog feature which can be used to help improve the clarity of images captured in 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. Visit www.samsungsecurity.com.
