car cam


Posted on Feb 6, 2014

There is now no need for a separate camera and recorder - for less money you can buy an integrated dash camera that will record in HD. Try the Techmoan blog for some reviews. Summary - this is a description of how to install a fairly cheap video recording system for use on track days etc, using a portable MPE

G 4 recorder and a CCD `bullet` camera. A power supply design is also included, aimed at people with experience of building electronic circuits. The recording device is a Mustek PVR-A1. This is a gadget about the size of a Nintendo Gameboy which can play MP3s, display photos and videos and, most importantly, record video. It accepts a composite video and stereo audio input and encodes video in MPEG 4 format at a resolution of 320x240. The built-in memory is very small so you`ll need to buy a flash card (SD or MMC format) if you want to record a useful amount of video. The camera is a miniature CCD `bullet camera` with 380 lines of resolution. You can buy it from RF Concepts in a pack that includes all the cables and mounting hardware you`ll need. I chose to mount it on top of the CD storage box in the middle of the car. It is possible to run both the camera and PVR from batteries, but to avoid the problem of batteries suddenly running out I built a simple power supply to run everything from the the car`s lighter socket. This consists of a low dropout 12V regulator to provide a stable supply to the camera, and a 5V regulator for the PVR. Most of the parts are available from your local Maplin, except the L4940V12 which you can get from Farnell (order code 413-197. ) The circuit can be built easily on a small piece of stripboard. You may need to experiment to get the right size power connectors for the camera and PVR. Note I...
