1/2.7" 2MP Lumii sensor, 1080p, 3~9mm F1.2 lens, ICR day/night, triple streaming: H.264/MPEG-4/MJPEG, PoE, ePTZ, microSD/SDHC card slot, vandal-proof, IP67


The premium NDF831 is a cutting edge 1080p camera equipped with mechanical (ICR) day/night switch for 24/7 surveillance. As part of MESSOA MegaSmart™ IP products family, the NDF831 features intelligent detection capabilitie including motion, audio, blur and network disconnection detection. It also supports local storage to micro SD/SDHC card to ensure nothing is missed in case the network goes down. Completely vandal-proof and IP67 water-proof, along with an optional heater, the NDF831 can withstand even the harshest of conditions. The NDF831 is a top-of-the-line solution for your security needs.


Lumii™ Technology

Our Lumii™ technology delivers high sensitivity images without blur. Lumii™ helps increase the sensitivity and reduces video noise in low light conditions. Night images become bright and clear.

Full HD 1080p Images

Clear and detailed full HD quality images in all conditions. Unlike traditional megapixel cameras, HD offers higher resolutions and better frame rates at an international industry standard. Blurry images are reduced and individuals and objects of interest come through in perfect clarity.

Cost-saving H.264 Support

The NDF831 Network Camera supports the H.264 compression standard. H.264 greatly reduces the size of video compared to MJPEG and MPEG4 without compromising image quality. Storage and bandwidth needs are reduced. Plus, H.264 is expected to become the video standard of choice, so your camera is future proofed.

PoE Facilitates Easy Installation

Built in support for Power Over Ethernet reduces cost and adds flexibility to the camera. A single cable connection is used to view, power, and control the camera. Installation cost are reduced since there is no need for separate cables.

Intelligent Detection Capabilities

The NDF831 has a variety of intelligent detection functions, including motion, audio, blur and network disconnection detection. The Smart Encoding function allows users to encode a specified region of interest (ROI) with higher bit rates for better image quality. Event-specific or region-specific monitoring enables you to receive alerts upon event and saves storage cost by only recording when a specific event happens.

ONVIF Compliant

ONVIF is an open industry forum for the development of a global standard for the interface of network video products. The NDF821 supports ONVIF thus allowing interoperability between network video products regardless of brand.

Continuous No-Interruption Recording

Record JPEG images or video clips for several days with the built in micro SD/SDHC card slot for up to 32 GB. Keep recording and prevent data loss even when the network goes down. Moreover, the camera's built-in FTP server enables users to view the saved files conveniently from a remote site.

Rugged Housing

The die-cast aluminum alloy housing is compliant with IK10 and IP67 standards, which protects the camera against extreme weather and impact, making it perfect for outdoor surveillance. An optional heater maximizes protection of surveillance equipment in extremely cold weather.
