4MP AcuSense Dome Camera with Built-in Microphone

Sharp Images Even in Harsh Light

Backlit scenes — bright windows, parking lot lights, or direct sun — usually wash out the image. This camera's 120dB True WDR captures detail in both bright and dark areas simultaneously. You see faces, license plates, and objects clearly, not as silhouettes.

AI That Filters Out the Noise

Standard motion detection triggers alerts for everything — leaves, rain, animals, passing cars. AcuSense technology classifies humans and vehicles on the camera itself. You only get notified when a person or vehicle enters the scene. Fewer false alarms mean faster response to real threats.

Hear What Happens — No Extra Gear Needed

A built-in microphone picks up audio alongside the video feed. You can hear footsteps, voices, or glass breaking in real time. No need to buy or install a separate audio device. Combined with the alarm input/output (1/1), you can also connect external sensors or lights for a complete security setup.
