Hikvision DS-QACAM07G1-4LIZSU 4MP DeepinView 7W Motorised Visible Horn Camera + Speaker

Overview

The Hikvision DS-QACAM07G1-4LIZSU is the headline model in Hikvision’s Visible Horn range — a single PoE+ device that combines a professional 4 MP motorised varifocal IP camera with an integrated 7 W IP horn speaker and dual electret microphones. Designed for sites that need both surveillance and active audio deterrent without running two separate cable drops, two power supplies and two RJ45 ports.

Internally the camera is built on Hikvision’s embedded open platform — the same architecture used on the iDS DeepinView range — meaning professional image effects, on-camera AI inference and a dedicated large-scale model for perimeter protection. Hikvision quotes a 90 % reduction in false alarms compared with conventional AI cameras for the same line-crossing, intrusion and region-entrance/exit events, with built-in target filtering by human and vehicle.

The integrated horn is a true 7 W dome-tweeter speaker, 8 Ω impedance, 107 dB sensitivity at 1 m/1 W, 115 dB maximum SPL and a 500 Hz – 6 kHz frequency response tuned for voice broadcast and audible deterrent. Hikvision rates the outdoor loudspeaker distance at up to 100 m, making it suitable for forecourts, builders’ yards, perimeters and large car-parks.

Why the Visible Horn?

• One device, two functions. Replace a separate IP camera + IP horn speaker stack with a single PoE+ install — halves your cable runs, switch ports and mount points.
• AI-triggered live audio deterrent. Perimeter-protection alarms can fireAjax Fire Alarm vs Intruder Alarm: UK Compliance for Combined Systems a live or pre-recorded announcement out the integrated horn — intruder hears a real warning the moment they cross the line, not after the event reaches a remote monitoring station.
• True 100 m outdoor reach. The dome tweeter is voiced for outdoor projection — not the “ish” 2–3 m chirp you get from a built-in speaker on a standard camera.
• Hybrid IR + white-light supplement. 50 m IR for night identification or full-colour 20 m white light when an alarm event triggers — combined optical + audio deterrent in a single trigger.
• Dual microphones for two-way talk-down, with AEC/NS/AGC/DRC echo cancellation and noise filtering tuned for outdoor conditions.
