Don't lose sight of anything -- in low light, or in complete darkness. With the Minimum Subject Illumination feature of the VC-C50i, you can still see what's happening even when light gets as low as 1 Lux (at 1/30 second shutter speed). Not only that, but when the lights go out completely, the camera's built-in Infrared (IR) source lets you continue to monitor the action. (The camera's IR illumination is effective up to 9.8 feet.) Nothing can stop the VC-C50i from giving you the images you need -even when the lights go out!
