MEGApix® 2.1 Megapixel Indoor Box IP Camera
Model: DWC-MC421D
The MEGAPIX™ IP cameras provide real-time 2.1MP (1080P) resolution with features such as 3D DNR, WDR and Smart IR, delivering superb image in any environment. And PoE simplifies installation, connecting power and network through a single cable. All cameras are OnVIF compliant, guaranteeing successful integration with any open platform solution.

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.
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.
Two-Way Audio
The Cameras support two- way Audio interaction. This allows communication to run between the camera’s web-based UI and the camera’s location.
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.
