AfterBurner-4: Evidential Video Recorder

4 Channel Evidential Video Recorder

AfterBurner-4 builds on the highly successful award-winning AfterBurner 1&2 range of evidential video surveillance recorders. Retaining the same footprint for ease of replacement, new features include 4 independent standard definition inputs along with one full-HD input (up to 1080p/30). The front panel user interface is based on the previous models, so little extra training is required for user operation.

Efficient evidence gathering

AfterBurner-4 utilises efficient H.264 video compression providing high quality images coupled with long record times. The record times can be extended further by using time-lapse modes, or by selective recording using internal video motion detection, timers etc. Evidence is burnt to write-once DVD or Blu-ray discs or optionally to a removable SSD drive for rapid retrieval. All files may be SHA256 hash coded by AfterBurner-4 to provide an evidential audit trail.    

Highly connected

Networking has been enhanced to allow for remote control and live monitoring via its Ethernet and WiFi* interfaces.  The unit has an easy to use web-page interface for control and setup, along with the ability to live stream in RTSP format to video management systems such as Genetech and Milestone. Ovation Systems also provide free server software to make the connection to remote devices from unknown IP address quick, secure and easy.
