12MP Smart Dual Light WizSense Eyeball Network Camera with Audio

Ultra HD Clarity for Critical Details

With 12MP resolution (4480×2512), this Dahua camera captures four times the detail of standard 1080p cameras. You can clearly read license plates, identify faces, and monitor wide areas without losing sharpness. The 2.8mm fixed lens provides a 112° horizontal field of view, covering large entrances, parking lots, or warehouse aisles in a single shot.

Smart Dual Light — Color Night Vision Without Guesswork

The Smart Dual Light system combines IR LEDs and warm white LEDs, automatically switching between three illumination modes based on scene activity. In complete darkness, the camera delivers clear black-and-white IR images up to 30 meters. When motion is detected, it can trigger white light for full-color details, helping you identify intruders or verify events in real time.

Built-in Audio for Complete Situational Awareness

A built-in microphone captures audio alongside video, so you hear what's happening — not just see it. This is invaluable for monitoring office environments, retail stores, or entry points where verbal warnings or conversations matter. No extra audio hardware or cabling is needed, saving installation time and cost.

Tough Enough for Any Outdoor Location

Rated IP67, this camera is fully protected against dust ingress and water jets, making it suitable for exposed outdoor installations. It operates reliably in temperatures from –40°C to +60°C, so you can mount it in freezing parking lots or sun-baked loading docks without worry. The metal and plastic housing resists corrosion and impact.

FAQ

Does this camera work with my existing POE switch or NVR?

Yes, it supports standard PoE (802.3af) and 12V DC power. It is ONVIF compatible, so it works with most third-party NVRs and POE switches. For best results, use a Dahua NVR to access all Smart Dual Light and AI features.
Can I use this camera indoors for an office or retail space?

Absolutely. While it is IP67 rated for outdoor use, its compact eyeball form factor and built-in mic make it ideal for indoor office camera applications. The 112° wide angle covers open-plan areas, and the audio lets you monitor customer interactions or employee areas.
How does the human and vehicle detection work?

The camera uses deep learning algorithms to distinguish people and vehicles from other moving objects like animals, leaves, or rain. You receive alerts only for relevant events, reducing false alarms. This is especially useful for busy commercial sites or parking lots.
What is the maximum SD card capacity supported?

The camera supports MicroSD cards up to 256GB. This allows for weeks of continuous recording locally, even if your NVR is offline. Use a high-endurance card for best reliability in continuous write operations.
