The Vivotek MD8531H is a compact, 1.2-megapixel network camera geared toward transportation applications such as buses, trains and other vehicles. With full EN50155 compliance and IP66-rated design, the camera can withstand shock, vibration, humidity, dust and temperature fluctuations, maintaining stable and reliable video during vehicle movement.

Furthermore, the vandal-proof metal housing effectively provides protection from vandalism. As such, the combination of high-resolution imaging and protective housing makes the MD8531H a good choice to maximize passenger safety and optimize mobile surveillance.

With its tamper detection feature, the MD8531H becomes a robust and intelligent camera that keeps security staff notified once it suffers video loss from being blocked or spray-painted. Power-over-Ethernet also allows the camera to be operated and powered with a single Ethernet cable, giving greater ease of installation. In order to facilitate on-board storage and data portability, the camera is also complete with a MicroSD/SDHC/SDXC card slot for local recording. In a corridor scenario, its video rotation feature can provide wider vertical coverage for more scene depth.

To better capture all important details, the MD8531H has a microphone to pick up audio, as well as a loudspeaker to use for applications such as background music, masking noise and return audio from a security control center. This could be used to give commands to the vehicle operator or passengers, possibly giving directions that could save lives and prevent injury.

Featuring WDR Pro wide-dynamic-range technology, it provides improved visibility in both dark and light environments. Combined with 3D noise reduction technology, which enables the MD8531H to capture clear video under low-light conditions and reduce bandwidth from sensor noise, users can identify an increased level of image details in situations where they might otherwise be obscured by noise.
