Why This Camera

Why This Camera.

Dual

Two lenses beat one

A single camera can only look one way. This one gives you two live views simultaneously — a wide-angle overview plus a zoomed-in close-up — so you never miss a thing.

Coverage

Covers the whole room

With full PTZ control and auto tracking, the camera follows movement and pans to keep every corner in view. One device replaces multiple fixed cameras.

Clarity

Clear footage, day or night

Full-color night vision with warm LED lighting means you see real colors and details after dark — not grainy black-and-white footage.

Simple

Simple, smart, and affordable

WiFi plug-and-play setup, smart detection that cuts false alerts, and two-way audio for staying connected. Everything you need in one compact, affordable device.

FAQ

What buyers usually ask.

What's the MOQ for OEM orders?

Trial orders start small — talk to us about your volume. Logo printing, custom packaging and firmware defaults are available on OEM terms; we scale with you from first sample to full containers.

Do both lenses record at the same time?

Yes — the fixed lens records continuously while the PTZ lens can be aimed, set to track, or zoomed. Both streams are accessible simultaneously in the app.

Can it be ceiling mounted?

Yes, with the included mount. Ceiling placement gives the fixed lens the cleanest 360° panorama and keeps the PTZ unobstructed.

What certifications are available?

CE, FCC and RoHS compliance for applicable destinations. Tell us your target market and we'll confirm the exact certification package and documentation for your customs clearance.

What about after-sales support?

We're a manufacturer, not a trading desk: spare parts, firmware updates and warranty handling come from our own factory in Shenzhen. Your customers stay supported — and so does your reputation.
