See More Detail in Low Light

The 1/1.8" progressive scan CMOS sensor captures sharp, clear images even in challenging lighting. With 8MP resolution at 3840 × 2160, you get four times the detail of 1080p. This camera performs reliably in low-light conditions, making it a solid choice for outdoor surveillance.

Hear What's Happening in Real Time

A built-in microphone lets you hear footsteps, voices, and other sounds alongside the video feed. No extra hardware needed. The camera also supports external audio input and output, so you can connect speakers or additional mics to expand your monitoring setup.

Smart Detection That Reduces False Alarms

AcuSense technology classifies humans and vehicles on-chip, filtering out nuisance alerts from leaves, rain, or animals. You get notified only when a person or vehicle is detected. This saves hours of reviewing useless footage and speeds up response to real threats.

Built for Outdoor Installation

The IP67-rated housing protects against rain, dust, and extreme temperatures from -30°C to 60°C. The IK10 vandal-proof rating resists impact. Flexible power options — 12V DC or PoE (802.3af) — make installation straightforward for any project.

FAQ

How does the built-in microphone work?

The built-in mic captures audio in real time alongside the video feed. You can hear what's happening — footsteps, voices, glass breaking — without needing to install a separate microphone.
What is AcuSense technology and how does it help?

AcuSense is Hikvision's AI-powered human and vehicle classification. The camera distinguishes people and vehicles from other motion, so you get fewer false alarms from leaves, rain, or animals. You only get notified when a person or vehicle is detected.
Can I use a MicroSD card for local storage?

Yes. The camera has a MicroSD card slot that supports cards up to 256GB. This gives you weeks of local recording without needing a separate NVR or cloud subscription.
Does this camera support PoE (Power over Ethernet)?

Yes. The camera supports PoE 802.3af, so you can power it and transmit data over a single Ethernet cable. It also supports 12V DC power if you prefer a traditional power supply.
