Hikvision AcuSense 4MP bullet 2.8mm lens 40m IR 120dB WDR dual-microphone built-in strobe-light & siren 12VDC/POE

★★★★★ "AcuSense alerts only on people, the dual mic picks up clearly, and the strobe scared off an intruder before they even got close." - Warren B., Centurion

Hikvision DS-2CD2046G2H-I2U/SL - AcuSense 4MP IP Bullet Camera with 40m IR, Dual Microphones, Strobe Light and Siren

The Hikvision DS-2CD2046G2H-I2U/SL is a 4MP AcuSense IP bullet camera combining deep learning human and vehicle detection with active deterrence - dual arrayed microphones, built-in strobe light, and audible siren. AcuSense ensures deterrence is triggered only by genuine human or vehicle detections, not false alarms from animals or environmental movement. Compatible with Hikvision NVRs and ONVIF platforms. Powered by PoE or 12VDC.

Why This Camera Stands Out

• AcuSense-Triggered Deterrence - The strobe and siren are linked to AcuSense deep learning classification - activating only when a human or vehicle is detected, not on every irrelevant motion event.
• Dual Arrayed Microphones - Two arrayed microphones provide higher-quality audio capture and better directional sound recording compared to a single microphone.
• Strobe Light and Audible Siren - Active deterrence that alerts intruders with a bright flashing light and loud audible alarm, potentially stopping a threat before it escalates.

Key Features

Why You'll Love It

The DS-2CD2046G2H-I2U/SL doesn't just record threats - it responds to them. AcuSense classifies the detection accurately, and when a human or vehicle is confirmed, the strobe and siren activate immediately. Add dual-microphone audio recording and you have a camera that deters, records, and alerts - all in one unit.

FAQ

Can the strobe and siren be triggered remotely from a phone? Yes. When connected to a Hikvision NVR with Hik-Connect app integration, you can manually trigger the camera's alarm output (strobe and siren) remotely from your smartphone.

What is the advantage of dual arrayed microphones over a single microphone? Arrayed microphones use two elements to improve sound directionality and reduce background noise, producing cleaner audio recording than a single microphone - particularly in outdoor environments with wind or ambient noise.

Does AcuSense need to be configured to trigger the deterrence features? Yes. AcuSense event linkage to the strobe and siren is configured in the camera or NVR's alarm settings. Once set up, the deterrence activates automatically on confirmed human or vehicle detections.
