The DFS-37 is 1/3" Sony EXview HAD CCD II sensor door frame camera. It features a 700 TVL high-sensitivity camera with 3.7mm lens housed in a low profile enclosure with a discrete 3/16” viewing slot. It can be adjusted to cover a full 90 degree field of view to the left and right of center, making it ideal for double doors requiring an angled view. The housing is sized to fit most standard door frames (1.7” width). The power and video cables are typically fed through the rear of the housing into the door frame but can also be channelled through the top or bottom of the unit using conduit.
