A 2MP PTZ dome camera with 33× optical zoom that finds a target anywhere in range and locks on: UNV's AI Large Model tracks motor vehicles, non-motor vehicles and pedestrians through occlusion and fast motion, with 200 m smart IR carrying the view into full darkness.
Sample quantities are welcome — testing one or two units first is the normal way to start.
The IPC6622SR-X33-VD2 is a 2MP PTZ dome camera built around a 1/2.8" CMOS sensor with 33× optical zoom (4.5-148.5 mm) plus 8× digital zoom, 120 dB true WDR and ColorHunter low-light imaging with Wise-ISP. UNV LM-Auto Tracking (UNV Large Model) identifies and continuously tracks motor vehicles, non-motor vehicles and pedestrians through occlusion, multi-target crossing or high-speed motion, backed by smart intrusion prevention (cross line / enter area / leave area / intrusion) with classification-based false-alarm filtering, and people-flow counting with crowd-density monitoring. A 200 m smart-IR illuminator, heatwave reduction, adaptive defog and adaptive highlight compensation keep images usable day and night, inside an IP67 / IK10 housing rated -40 °C to 70 °C.
Plain-language guide for buyers and installers — based only on what this camera actually does.
For corporate buyers: we support submitting the purchase order to Uniview under your company's real name — your company appears on the official order, so the origin of the goods can be verified directly with the manufacturer. Just provide your company name and pay by corporate bank transfer. Models carrying the anti-counterfeit label can also be self-verified on Uniview's official Anti-Counterfeiting Query page — enter the unit's SN plus the scratch-off code.
For small and mid-size orders, we deliver directly to your designated forwarder's warehouse in China (EXW / FOB Guangzhou). From hand-over onward, international shipping and destination-side arrangements are handled by your forwarder — the way you already work.
Complete list from the official datasheet.
Both work automatically once enabled, from the official datasheet.
Continues tracking through occlusion, multi-target crossing or high-speed motion with real-time adaptive bounding boxes.
Automatically adjusts image settings for natural, realistic night images, paired with adaptive HLC for oncoming headlights.
DORI (EN 62676-4) is the industry standard for what a camera can do at distance. Values shown are at full 33× optical zoom (148.5 mm); the datasheet also lists 72.9-218.8 m at the 4.5 mm wide end.
