Clear Footage in Any Light

This 4MP camera uses a 1/2.9" CMOS sensor and 120dB True WDR to capture sharp images even in strong backlight. Whether it's a sunny parking lot or a dim warehouse, you get usable video every time. The 2.8mm or 3.6mm fixed lens gives you a wide 95° horizontal view.

Smart Alerts That Matter

WizSense SMD Plus filters out false alarms from leaves, rain, or animals. It detects only people and vehicles, triggering intrusion and tripwire alerts. You get fewer notifications and more actionable intelligence. No more wasted time checking empty footage.

Built-in Audio, Easy Installation

A built-in microphone captures real-time audio alongside video — no extra hardware needed. Power the camera via 12V DC or PoE (802.3af) for a single-cable setup. Record locally on a MicroSD card up to 256GB, or connect to any ONVIF-compatible NVR.

Built for Outdoor Use

The metal housing carries an IP67 rating, so rain, dust, and extreme temperatures from –40°C to +60°C won't stop it. The integrated IR LEDs provide 30m of night vision, delivering reliable black-and-white footage after dark. Install it once and trust it for years.
