The MegaDome2 AV3256PMIR-SA 3MP H.264 All-in-One Motorized P-Iris Lens Day/Night IR Indoor/Outdoor Dome IP Camera with WDR & 2-Way Audio Support from Arecont Vision delivers 2048 x 1536 resolution at a 21 fps frame rate to capture every detail whether viewing live or recorded/archived video. It comes with a 3 to 9mm wide angle motorized P-Iris lens that offers depth of field and image clarity. This true day/night camera comes with a removable IR-cut filter that allows the camera to select between color and B&W modes depending on the lighting conditions. It also features 24 IR LEDs that are effective up to 50' (15m), allowing the camera to adapt to constantly changing lighting conditions and capture high-quality images.
The camera can capture clear images in extreme lighting conditions thanks to the MegaDynamic WDR (Wide Dynamic Range) function. The camera offers WDR up to 100dB at full resolution, which balances light and dark areas in the same scene, such as in the lobby of an office building or the loading dock at a distribution facility. In addition to the day/night operation, this camera also includes pixel binning mode that provides increased low-light sensitivity and reduces noise.
For easy installation, the camera can be installed without locally adjusting the field of view or focus, thanks to the remote focus and zoom feature. Focus and zoom function can be controlled remotely through the camera webpage. The added P-iris functionality provides an automatic, precise iris control. Short or full range focus scan functions analyze the local or full scene to determine the optimum focus for the chosen field of view. With the ability to digitally pan-tilt-zoom (PTZ) images, you can view the details you need to see at any time, such as license plates, faces, and other objects of interest.
With CorridorView, the MegaDome2 camera can rotate or flip pixels in 90° increments, which makes it suitable for installation in narrow hallways where pixels are often wasted capturing the surrounding walls. It is a total PoE solution eliminating additional power wiring for the camera and IR LED ring. The camera is packed into an IP66 environmental-rated and IK-10 impact-resistant dome housing, making it suitable for a variety of indoor and outdoor applications.
