FORT WORTH, TX / ACCESS Newswire / May 15, 2026 / Vadzo Imaging, a provider of embedded vision solutions, today launched the Wave‑821CRE Day Night camera, 8MP HDR Wi‑Fi camera that integrates the Onsemi HyperLux AR0821 HDR sensor with a 2.4 GHz Wi‑Fi interface. The Wave‑821CRE functions as both a 4K HDR Wi‑Fi camera for daytime wide‑dynamic‑range scenes and a low‑light‑optimized day-night camera using the sensor’s native HDR. Vadzo built this AR0821 HDR camera to eliminate blown highlights and lost shadows while providing untethered operation over standard wireless networks. Applications include robotic perception, AGV navigation, drone payloads, traffic monitoring, security surveillance, and industrial inspection.
Sensor and Camera Overview
The Wave‑821CRE ONVIF camera uses the Onsemi HyperLux AR0821 CMOS sensor, an 8MP (3848 x 2168) color rolling shutter imager with on‑chip High Dynamic Range, a 1/1.7‑inch optical format, and 2.1 µm pixels. The AR0821’s HDR captures detail in both bright sunlight and deep shadows simultaneously – a critical requirement for traffic monitoring camera applications such as license plate recognition under glare, security camera deployment with backlit scenes, and robotics camera operation in mixed lighting. The sensor’s quantum efficiency and low noise floor deliver clean 4K HDR video even under rapidly changing light.
The Wave‑821CRE integrates a 2.4 GHz 802.11 b/g/n Wi‑Fi module, an S‑mount (M12) lens holder, and an onboard ISP. The camera streams MJPEG or H.264 over TCP/IP to any networked client. Power is supplied via a 5V micro‑USB or optional 2‑pin header. The default lens is a fixed‑focus S‑mount lens factory calibrated for typical working distances of 1 m to 10 m.

Key Capabilities of the Onsemi AR0821 8MP HDR Wi‑Fi Camera
True High Dynamic Range Eliminates Glare and Shadow Loss
Most wireless cameras use software tone mapping, which crushes shadows or clips highlights. The AR0821’s on‑chip HDR captures all 8 million pixels with two or three separate exposures combined at the sensor level. This 4K HDR camera reads license plates against direct sun, sees into dark warehouse aisles from a bright loading dock, and tracks people moving from shade to sunlight without losing detail. For video surveillance camera teams, this means reliable evidence in every lighting condition.
Day/Night HDR Without an Electromechanical IR Filter
The AR0821 HDR algorithm maintains color accuracy and contrast from full sunlight to twilight without moving parts. This day night camera automatically adjusts exposure and dynamic range curves, eliminating the failure points of mechanical IR filters. For outdoor security camera and traffic monitoring camera deployments, reliability improves with no motorized components.
S‑Mount Flexibility with Factory Focus
The Wave‑821CRE ships with a fixed‑focus S‑mount (M12) lens, pre‑calibrated for a specific working distance. Because it is an S‑mount camera, the lens can be swapped for different fields of view – wide angle for drone mapping or narrow for kiosk face recognition. For OEM customers, Vadzo offers custom focus distances and lens choices.
4K, 1080p, 720p, and VGA Streaming Modes
The 4K camera runs at full 8MP resolution for detail‑rich inspection. Downscaling to 1080p, 720p, or VGA reduces bandwidth for edge AI inference or wireless transmission. Resolution changes on‑the‑fly via simple HTTP commands. One 4K Wi-Fi camera serves multiple roles – high‑definition recording, real‑time analytics, and remote monitoring. It operates as a 1080p Wi‑Fi camera, a 720p Wi‑Fi camera, or a VGA Wi‑Fi camera, depending on bandwidth.
Easy Integration for Linux, Windows, and RTOS
The Wave‑821CRE day night camera enumerates as a network camera on the LAN. A web‑based configuration page allows setting Wi‑Fi credentials, stream URLs, and HDR behavior. For Linux hosts, GStreamer pipelines are provided. For Android or iOS, the camera speaks standard RTSP. This 8MP HDR Wi-Fi camera reduces months of integration to hours.
“Engineers ask for a wireless camera that does not wash out highlights in sunlight and still sees shadows. The AR0821 sensors on‑chip HDR deliver artifact‑free 4K video across a 120 dB dynamic range. Add Wi‑Fi for remote streaming, and the Wave‑821CRE becomes the most flexible 8MP HDR camera for robotics, traffic, and security. Vadzo built this camera to cut cables without cutting image quality.” – Alwin Vincent, Product Manager at Vadzo Imaging.
Applications
Smart Surveillance and Perimeter Security – The Wave-821CRE’s 140+ dB embedded HDR and ONVIF Profile S/T/G/M compliance make it a natural fit for professional security deployments. Backlit entrances, sun-glare on perimeter fences, and day-to-night transitions that break conventional cameras are handled by the AR0821’s in-pixel DR-Pix™ processing. Power over Ethernet simplifies installation at parking structures, building perimeters, and temporary event sites where running separate power is impractical. ONVIF compliance means direct integration with existing VMS platforms without custom drivers.
Smart Traffic Management and Intelligent Transportation – License plate recognition under direct headlight glare, vehicle classification across shaded and sun-lit lanes, and intersection monitoring from dawn to dusk demand dynamic range that exceeds what standard sensors can deliver. The AR0821’s 140+ dB eHDR captures clean 8MP frames in conditions that wash out or crush detail on conventional traffic cameras. IEEE 1588 PTP synchronization enables frame-accurate coordination across multi-camera intersection deployments. Wi-Fi connectivity allows placement at road segments where fiber or Ethernet infrastructure is absent.
Parking Lot Management and Access Control – Entry and exit lanes present some of the hardest HDR scenarios – a dark interior, bright exterior sky, and vehicle headlights all in one frame. The Wave-821CRE resolves plate detail and driver faces simultaneously. Wi-Fi eliminates the need to trench cabling across paved surfaces, and ONVIF integration connects directly to access control and parking management platforms.
Medical Imaging and Surgical Monitoring – Surgical suites combine intense point-source illumination from surgical lights with lower ambient levels, creating extreme local contrast. The AR0821’s in-pixel HDR preserves tissue texture and color accuracy across this range without the motion artifacts introduced by multi-frame software HDR – critical where a single clear frame matters. Wireless streaming via Wi-Fi reduces cable clutter in sterile environments and simplifies camera repositioning between procedures.
Sports Analytics and Stadium Surveillance – Wide-field sports venues mix direct sunlight, deep shadow under stands, and rapidly moving subjects – a demanding combination. The Wave-821CRE’s 8.3MP resolution enables post-capture crop and zoom for player tracking, while HDR prevents blown highlights when cameras face sunlit sections of the pitch. Wi-Fi deployment avoids the need to run structured cabling across seating tiers and concourses.
Robotics, AGV, and Industrial Inspection – Autonomous mobile robots and AGVs navigating warehouse environments face bright overhead skylights and dark aisle interiors in the same frame. The Wave-821CRE day night camera mounts directly to an AGV chassis and streams to a central fleet management system over the facility Wi-Fi. For conveyor inspection, the AR0821’s HDR handles the reflectivity differential between shiny metal surfaces and matte packaging without the glare washout that defeats standard sensors.
Frequently Asked Questions (FAQs)
1) Why does the Wave‑821CRE use on‑chip HDR instead of software tone mapping?
Software tone mapping applies a curve after the fact, which cannot recover lost highlights or crushed shadows. The AR0821’s on‑chip HDR captures multiple exposures at the sensor level, preserving detail across a true 120 dB dynamic range. Vadzo Imaging chooses hardware HDR because it delivers evidence‑grade images for security and traffic applications, not just consumer‑grade “looks good” video.
