4MP AcuSense Smart Hybrid Light Bullet Camera with Built-in Mic

Clear Footage Even in Harsh Light

Backlight ruins security footage — bright windows, headlights, or direct sun wash out details. This camera's 120dB True WDR balances exposure so you see faces and license plates clearly, not just silhouettes. Combined with 4MP resolution at 30 fps, you get sharp, usable video in challenging lighting conditions.

AI That Filters Out Nuisance Alerts

Standard motion detection triggers on everything — leaves, bugs, rain, shadows. AcuSense technology classifies humans and vehicles on the camera itself, so you only get alerts that matter. Line crossing and intrusion detection work with the same AI, making perimeter monitoring reliable without constant false alarms.

Smart Light That Adapts to the Scene

Most cameras force you to choose between IR (black-and-white, no light pollution) or white light (color, but always on). The Smart Hybrid Light gives you both — IR for quiet monitoring, then switches to warm white light when motion is detected. You get color footage and a visible deterrent, but only when it matters.

Built Tough for Outdoor Installations

IP67 rating means this camera handles rain, dust, snow, and temperature swings from -30°C to 60°C. The metal housing with IK10 vandal-proof rating resists impacts and tampering. Power it over PoE for a single-cable install, or use 12V DC if that's what's available on site.

FAQ

Does this camera work with standard PoE switches?

Yes, it supports PoE 802.3af. Plug it into any PoE switch or injector for power and data over a single Ethernet cable.
Can I use this camera without an NVR?

Yes. It has a microSD card slot supporting up to 512GB for local recording. You can also stream directly to a PC or NAS using RTSP/ONVIF.
What is the night vision range?

The IR LEDs provide up to 40 meters of night vision in complete darkness. The Smart Hybrid Light also switches to white light for color imaging when motion is detected.
Does the built-in microphone support two-way audio?

No, the microphone is listen-only. It captures clear audio from the scene, but there is no speaker for two-way talk. For two-way audio, look for a model with /SL suffix.
