Purpose: getting images from analog security surveilance cameras with the lowest possible price.
Function: capturing video frame from analog video signal for subsequent compression into JPEG file and saving in internal memory for following transmission to any master device via simple USART interface.
Possible applications: in a low cost wireless fire alarm and security systems as a video alarm verification unit, wireless video survailance systems, toys, etc.
Cost: ~14$.
Characteristics:
Number of video inputs - 4
Video signal presence control - yes
Embedded memory size - 16 frames
Resolution: 720*576 or 360*288.pixels
Max speed of taking photos: ~2 frames/sec.
Ability to record auxiliary information into image file up to 75 characters(for example it can be the camera number and time when the photo was taken).
Video signal characteristics: bw/color, PAL (NTSC is planned), composite, interlace (this is a signal from even analogue survailance video camera).
Power supply: 5 - 15V, 120мА DC.
Interface: UART 115200 bit/sec, format 8N1, software flow control is available (only while image file is transmitted).
Size: 49мм * 49мм * 18мм.
Other: allows to see images from connected cameras on notebook during installation via USB-USART interface cable.
