Audio-Video Recoder  
• Micro Audio Video Digital Recorder is intended for covert and mobile recording of video as we as audio inputs through a camera and microphone on a compact memory flash card which can be read through a CF card reader.
• µ AVR is of a very compact and small size, consumes very less power which is supplied through an inbuilt Li-Polymer rechargeable battery of capacity 1750mA/Hr.
• The software supplied is compatible with Windows 9x/Me/NT/2000/XP. The Audio Video files can be saved in AVI formats. The recording parameters can be set as per requirements.
• Technical Parameters:
• Resolution of saved video is 352x288 or 176x144 pixels
• Supports PAL. Colour and monochrome video signals
• Frame frequency during recording – 25, 12, 6, 3, 1 frames per second.
• Audio frequency band 300-6600 Hz (sample rate 16 kHz), 300-3300 Hz ( sample rate 8 kHz)
• Audio sensitivity of built in microphone up to 5 mtrs.
• Dimensions: 53x65x15 weight 75 gms
• Operating temperature -10° to +60° C
• Recording time depends proportionally on CF card capacity, Video quality, frame frequency, the set compression rate, resolution (for 176x144 pixels it is 3 times longer) Moreover the recording time also depends significantly on the movements in the picture, and finer details. If there is very less movement, the time can increase 10 fold. Below is an approximate recording time on a 2 GB CFcard:
• 176x144 pixels, B/W, 1 fps, no audio, normal quality, almost static picture – 100 hrs
• 176x144 pixels, colour, 12 fps, audio 8 kHz, medium quality, 25% movement – 15 hrs
• 176x144 pixels, colour, 25 fps, audio 16 kHz, high quality, 25% movement – 6 hrs
• 352x288 pixels, colour, 12 fps, audio 16 kHz, high quality, 25% movement – 4 hrs
• 352x288 pixels, colour, 25 fps, audio 16 kHz, high quality, 25% movement – 2 hrs
• Operation time with fully charged rechargeable battery depends on the recorder operation mode:
• Video recording – 6 hrs
• Standby mode – 1 year
• Water mark support
• Supports 8 recording profiles
• Inbuilt clock and calendar
• Linear and Circular recording mode
• Optional remote control system provides 12 volts DC supply to camera for operation, additional external microphone for added sensitivity. The system can be switched on/off through a micro switch which can be concealed.
