180° Wide View with Pixel-Level Fusion

This Dahua 180 degree camera uses dual 1/2.7" CMOS sensors and pixel-level splicing fusion to create a single, distortion-free panoramic image. You get 4096 × 1860 resolution — covering wide driveways, parking lots, or warehouse aisles with one camera instead of two. The 2.8 mm fixed lens delivers a 180° horizontal field of view, so nothing slips past the edges.

Active Deterrence with TiOC Technology

TiOC combines red and blue warning lights with a built-in alarm siren to actively scare off intruders. When the camera detects a person or vehicle (via SMD 4.0), it triggers the lights and sound automatically. You can also use the built-in dual mic and speaker for real-time two-way talk — warn someone off or communicate with a delivery driver without leaving your desk.

Smart Dual Light for 24/7 Color Imaging

The Smart Dual Light system switches between IR and white LED illumination based on the scene. In low light, it uses IR for discreet monitoring. When motion is detected, it activates white light to capture full-color details — useful for identifying suspects or vehicle colors. Three illumination modes let you customize the behavior for your site.

Built Tough for Outdoor Installation

Rated IP67, this bullet camera handles rain, dust, and temperature swings from –40°C to +60°C. The metal housing protects against impact and corrosion. Power it via 12V DC or PoE (802.3af) — one cable for data and power simplifies installation. A 512GB microSD slot supports weeks of local recording without an NVR.

FAQ

Does this camera really cover a full 180 degrees?

Yes. The dual sensors and pixel-level splicing fusion create a single 180° horizontal field of view. You get a seamless panoramic image without distortion.
Can I use this camera with a Dahua NVR?

Yes. It works with Dahua NVRs and supports ONVIF for third-party compatibility. Use the DMSS app for remote viewing on your phone.
How does the active deterrence work?

When the camera detects a person or vehicle, it activates red and blue warning lights and plays an alarm sound. You can also trigger two-way talk through the built-in mic and speaker.
What is the night vision range?

The IR illuminators reach up to 25 meters. The Smart Dual Light also provides white light for full-color night imaging when motion is detected.
