§ 04Why choose this
Built for the way you actually use the IPC-B261H-MU
AcuSense Human & Vehicle Detection
Deep learning separates people and cars from animals and leaves. Fewer false alerts than basic motion detection.
40 m IR Night Vision
Longer range than most budget bullets. Covers a full driveway or backyard fence line in the dark.
120 dB True WDR
Handles bright doorways and shaded areas in the same shot. Useful where a sensor light creates contrast.
Built-in Microphone
Records ambient audio. Adds context to footage — hear a door slam, glass break, or conversation.
§ 05Where it fits
Right at home in these scenarios
Driveway or Fence Line
Bullet shape aims naturally down a long run. 40 m IR covers the full length of most residential driveways.
Side of House or Gate
Compact and discreet. IP67 handles rain and sprinklers. AcuSense ignores cats and possums.
Small Warehouse or Yard
Mount on the wall above the roller door. 6 MP gives enough detail for identifying visitors. PoE simplifies the cable run.
Backyard and Shed Area
Point at the back fence or shed. 120 dB WDR handles the contrast between a lit patio and dark lawn.
