Development of mAVR H264 series

Professional miniature Audio and Video Recorder mAVR H.264x4.

Distinctive features compared to mAVR H264S:

•    bitrate (recording speed of video data onto memory card)  enhanced by 3,5 times which provides improved video recording quality;
•     opportunity to use four SD cards: each up to 32 Gb, which means that maximum recording capacity is up to 128 Gb, that is recording for more, than 60 hours;
•     battery life enhanced by 4 times (compared to mAVR H264).

Control and indication of operating modes are the same as in mAVR H264S.

Video Recorder MAVR-H264x4 is intended for professional recording of video and audio data either from an external source or from built-in video camera and microphone onto SD or SDHC flash memory cards at the capacity up to 32 Gb. The recorder provides the opportunity to insert up to 4 memory cards for alternate recording.


  •     Video recording either from an external source or from the built-in recorder video camera (AVC format, H.264) providing resolution 640x480 for video camera or 720x576 (for an external source)
  •     Disposition of text onto video signal (date, time, GPS data, text line) – up to 2 lines with 24 symbols each (depending on the resolution selected)
  •     Option to set video signal parameters (brightness, contrast, saturation, color)
  •     Built-in clock and calendar with an option to correct their accuracy
  •     Opportunity to set time and date according to GPS signal
  •     Starting the recording by switch, timer, control input signal, motion detector or VAS (Voice Activating System) actuation
  •     Opportunity for circular recording onto memory card (one or several)
  •     Prehistory recording
  •     Video signal scaling (image compression) and cropping up to 96x96
  •     Adjustable video signal filtering
  •     Independent setting of bitrate for audio and video stream
  •     Adjustable frames per second for video stream
  •     Elimination of flickering caused by day electric lamps etc (at the frequency 50 and 60 Hz)
  •     Power supply either from an external source or by built-in Li-ion rechargeable battery. When powered from an external source rechargeable battery is charging
  •     The recorder can provide power supply for an external power consumer (for example video camera) with output voltage option (5 or 12 V)
  •     Audio recording format: mono or stereo
  •     Parameters setting, using menu or with the help of manager program
  •     Opportunity to upgrade internal software
