Originally the PIR (passive
infrared) covert cameras were developed as a
method for monitoring cash registers in
retail stores, the PIR camera has evolved
into one of the most versatile covert
cameras available. At home, in the office,
warehouse or manufacturing environment, the
PIR camera is available in hardwired models
with a down view camera in one area, makes
this the perfect choice for a small or a
medium sized business. All of the PIR
cameras have a 3.7mm 78° field of view
pinhole mini lens. The color cameras have
480 lines of resolution and low 0.4 lux
rating.
