Remote Zoom and Focus — No Ladder Required

The motorized varifocal lens (2.7–13.5 mm) lets you adjust the field of view remotely from your NVR or mobile app after installation. Mount the camera once, then fine-tune the angle and focus from your desk. This saves hours on multi-camera installs and gives you flexibility to change coverage later without touching the hardware.

Hear Every Sound with Built-in Mic

A built-in microphone captures audio alongside the video feed — no extra hardware needed. Listen for footsteps, voices, or breaking glass in real time. Combined with 8MP Ultra HD video (3840 × 2160), you get both visual and audio evidence of every event.

AI That Filters Out False Alarms

AcuSense technology classifies humans and vehicles, ignoring leaves, rain, and animals. This cuts nuisance alerts by up to 90% so you only get notified about real threats. The 120 dB True WDR ensures clear images even against bright backlight, making identification reliable in challenging lighting.
