MEGApix® 2.1 Megapixel Surface Mount Indoor/Outdoor Vandal Dome IP Camera with IR
Model: DWC-MF21M4TIR
The MF21M4TIR MEGApix® camera is a dual codec Surface Mount Outdoor Dome network camera that provides 1080P megapixel resolution at 30 frames per second. The camera’s advanced technologies such as True Day and Night, 3D-DNR, WDR, and Smart IR will deliver the best images in any type of environment. Power over Ethernet will simplify installation by connecting both power and network through a single cable. Housed in our attractive vandal-resistant aluminum die-cast dome enclosure.

Smart DNR™ 3D Digital Noise Reduction
Smart DNR™ 3D Digital Noise Reduction increases the camera’s clarity in very low light environments by using a unique algorithm to clean electronic noise signals that can reduce the camera’s visibility and trigger false motion detection events. DW®’s special noise reduction technology allows the camera to produce clearer images in both color and B/W in low light without creating lag or ghost effects in the image.
PoE Support to Power IP Cameras Locally
The NVR’s local PoE interface enables the NVR, combined with the DWC-BVI2IR, 2.1MP bullet cameras as a simple plug-n-play solution with the cameras powered, configured and controlled all from the NVR’s local GUI.
Smart IR™
Smart IR™ adjusts the image for IR cameras to eliminate LED light reflection and white spots in the image. By breaking down the camera’s field of view into five zones, Smart IR allows for even distribution of the IR light. This prevents excessive illumination on images that are in the front of the scene and offers a clear image in B/W without any loss of detail.
TDN [True Day/Night] with IR Cut Filter
During daylight, the IR cut filter allows visible light to pass through, reflecting the unwanted infrared light. In low light environments, where artificial or external light is not available, the cut filter is removed from in front of the lens, allowing the camera to capture the infrared light that given out from the infrared LEDs, to capture as much light as possible to produce brighter images.

Triple Codecs (H.264, MJPEG, MPEG4) with Simultaneous Dual-Stream
The cameras allow you to optimize your bandwidth usage, by offering simultaneous streaming. This allows you to stream high resolution for live monitoring and motion events, and setup a lower resolution streaming profile for when no activity is detected. This allows the camera to seamlessly transition between low and high resolution streams to maximize bandwidth usage, reduce network traffic and improve your overall system’s performance and power.
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.
