Depending upon the scene and lighting conditions, the camera offers AWB, AGC, AES, and BLC controls which you can set to optimize image performance. The Night-Saver mode automatically switches the cameras to B/W in scenes with less lighting to provide you with better low-light detail performance. These cameras feature internal and phase adjustable line-lock options for “roll-free” switching. The cameras are available in NTSC formats with 24 VAC/12 VDC voltages to meet a variety of application requirements. Cameras offer the same features as the but also include a moving mechanical IR cut filter that provides True Day/Night functionality. For scenes with typical lighting such as daylight or lit indoor applications, the camera provides a 540 TVL super, high resolution image.
