Equipped with dual-lens optics, large F/1.0 aperture, ColorX full-color night vision, dual PIR sensors and AI-powered motion detection, the B740X provides continuous monitoring for indoor and outdoor placement.

Advantages

The camera delivers 4K resolution across a 180° horizontal view to capture wide areas without blind spots. ColorX technology and large-aperture lenses enable clear full-color night images without relying on IR illumination, which helps extend battery standby time. Built-in AI combined with dual 180° PIR sensors reduces false alarms by distinguishing humans, vehicles and other motion types. Dual-band Wi‑Fi ensures smoother live streaming while IP66 weatherproofing allows reliable outdoor use. Two-way audio and support for voice control add convenient remote interaction.

Recommendations

Place the camera at a height that maximizes the 180° coverage while avoiding direct exposure to strong light sources.
