Motorized Zoom Auto-Focus Lens
An Auto Focus lens with motorized zoom removes the need for the complicated and detailed manual focus adjustment or zoom configurations at the camera. The motorized zoom module allows you to adjust the camera's view and zoom remotely, without the need to be near the camera. Then, the autofocus lens communicates with the camera to automatically determine what area of the camera’s FoV should be in focus.
CleanView™ Hydrophobic Dome Coating Repels Water, Dust and Grease
Digital Watchdog's new CleanView™ dome enclosures repel water and dust to maintain a camera's image quality. A technologically-advanced coating alleviates spotting and smudges that can affect the performance of the camera.

Cold Start
Our upgraded Snapit™ and B4 models come with a heater built into the camera module. This heater helps the camera power up in extreme cold weather conditions where temperatures may go as low as -40°F. This makes the cameras ideal for any harsh environment installation.
Wide Dynamic Range (WDR)
Wide Dynamic Range technology mechanically allows capturing an entire scene in challenging lighting conditions. One shutter is set to a short exposure, capturing the bright areas in the FoV, while the other is set for a long exposure, capturing the dark areas in the FoV. The camera then interlaces the images and combines them, capturing both areas with no loss of detail. This allows for an image capture even when there are very bright and dark areas in the camera’s field of view or images are distorted by a strong backlight.
