3MP indoor Wi-Fi camera with a real motorized pan-tilt head — 338° pan, -5° to 55° tilt, Auto Tracking and two-way audio. No network cable, just power and connect over 2.4GHz Wi-Fi.
Sample quantities are welcome — testing one or two units first is the normal way to start.
The Uniarch Uho-S2E-M3-A is a 3MP indoor Wi-Fi camera with a real motorized pan-tilt head, not just a fixed mount angle. It pans 338° and tilts from -5° to 55°, with Auto Tracking that follows moving subjects and 20 presets for jumping straight to a spot you check often. Built-in mic and speaker support two-way audio, and it detects humans, vehicles, pets and even crying, all over Wi-Fi with no network cable required.
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.
