It is amazing how much performance is packed into the WV-CP254H. The camera measures only 67mm wide by 72.5mm deep (2-5/8 x 2-7/8) yet it packs features and performance you would expect to find on cameras more than twice its size.

Additional performance features include a horizontal resolution of 480 lines in color and 570 lines in black-and-white: 50dB signal to noise ratio; minimum illumination of only 1.0 lux(0.1 fc) in color, and 0.15 lux (0.015 fc) in black-and-white at F1.4 lens (optional): Back Light Compensation (BLC), Aperture Correction, Automatic Gain Control (AGC), and Automatic Tracing White Balance (ATW). The WV-CP254H small size and big features make it the ideal choice for numerous applications.
