Smart Witness SVC-1080LCA Commercial Lockable Accident Camera with 32GB SD card supplied
We found the most reliable commercial grade independant accident recorder we could find and here it is.
DVR 2CH - 2 Channel DVR - 4 Pin connectors - Upto 128GB SD card - Can output 2 way split or individual channels
We were often asked for rear and sometimes side recording capabilities but people often found that the only systems offered were 4 channel versions, which cost a lot and were overkill for their needs. After moaning at our contacts in asia repeatedly we eventually managed to get what we wanted, a two way recorder that is simple to use.
