8MP AcuSense Varifocal Bullet Camera with Smart Hybrid Light

Clear Images in Tough Light

Backlight ruins security footage — but this camera handles it. With 120dB True WDR, you get usable video even when the sun blazes through a doorway or streetlights create harsh shadows. The 1/2.8" progressive scan CMOS sensor captures 8MP resolution at 20 fps, so details stay sharp in mixed lighting conditions.

Smart Detection That Saves Time

AcuSense AI processes video on the camera itself. It classifies humans and vehicles, ignoring motion from leaves, rain, or passing animals. You get fewer false alerts and faster response to real threats. The camera also supports line crossing, intrusion detection, and face detection — all without a separate server.

Install Once, Adjust Remotely

The motorized varifocal lens (2.8–12 mm) lets you set the field of view from your desk. No ladder needed. After mounting, you can remotely zoom and focus through the NVR or mobile app. The built-in microphone adds audio monitoring without extra wiring. One camera covers wide or narrow scenes — perfect for installers.

Built Tough for Outdoor Use

IP67 rating means the camera survives rain, dust, and snow. IK10 vandal-resistant housing protects against impacts. The Smart Hybrid Light provides up to 60 m of IR for invisible night monitoring, then switches to white light when motion is detected — giving you color footage and a visible deterrent.

FAQ

Can I adjust the zoom after the camera is mounted?

Yes. The motorized varifocal lens lets you remotely adjust zoom and focus from your NVR or Hik-Connect app. No ladder needed.
Does this camera have a built-in microphone?

Yes. It has a built-in microphone for real-time audio monitoring. Note that it is listen-only — no speaker for two-way talk.
How does the Smart Hybrid Light work?

The camera uses IR LEDs for invisible night monitoring most of the time. When motion is detected, it switches to warm white light for color footage and active deterrence.
Will this camera work with my existing NVR?

It works with Hikvision NVRs and supports ONVIF for third-party compatibility. For best results, use a Hikvision NVR with AcuSense support.
