These are the latest technology version of the very popular twin lens bracket camera we do. These have a slightly different design bracket, looks more modern. The bracket is made from stainless steel (we are one of the very rare sellers to have this) and will last a long time without rust. The image sensors are 1/3" Sony CCD meaning a better picture day and night compared to the 1/4" Sony and CMOS versions out there. These use the 4 pin connector cables found on our 4 pin connector monitors.
