"SRP 200"

The Crow SRP-200 is one of the most competitively priced spherical lens motion detectors on the market today. It utilizes the exclusive Crystal Vision lens which is 5 times more efficient than a traditional "soft fresnel lens". The SRP-200 is an ideal blend of quality engineering and cosmetic design to fit the most discriminating taste for any residential and small commercial application. The latest in electronic P.C. board design coupled with the hard spherical lens technology has created a detector that will provide you with years of trouble free service at prices that fit any alarm system budget.

The spherical lens has both a horizontal curve and a vertical curve of exactly 270 degrees which together focus the infrared energy on a single focal point. This keeps the targets' image on the lens. Therefore, there is never a need to adjust the optics either horizontal or vertically. Just mount an SRP sensor between 5' and 12' and walk away.

The perfect-fit case has extra room for the entry and connection of wires and an extra wide channel on the back for surface mounting the detector. The case allows for a simple snap-in connection for the lens with no need for re-attaching additional plastic brackets and screws to hold the lens in place.
