micro audio and video recorder avr series - Model avr-4

Long duration micro Audio and Video recorder with long-lasting battery life

The Micro Audio and Video Recorder AVR-4 records 1 channel of video and 1 channel of audio information on a regular compact flash card. The recorder has extremely small size (65x54x25), even less than a regular cigarette pack. Standard replaceable batteries make it perfect for portable and mobile applications. Very low power consumption provides up to 11 hours of operation in record mode. The recorder supports maximum resolution 704x288 (PAL) or 704x240 (NTSC) and features a wide range of software options such as motion detector, VAS, adjustment of audio and video recording parameters. The recorder can be powered either by 3 standard replaceable AA batteries or 3 NiMH rechargeable batteries of the same format, therefore it does not require a special charging unit. The duration of recording is directly proportional to the capacity of the rechargeable batteries, and it could even be longer than that of mAVR-2 and mAVR-3M. For example, 2500 mAh rechargeable batteries provide 11 hours of operation in record mode and up to 2 years in stand-by mode. The internal compression format is Wavelet. The output file is in *.avi format. At decoding a user can select a codec and setup its' parameters. Date/time stamp and watermark protection makes the recorder useful for evidence purposes.
