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.

Specifications:

•     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
