Sharp Images Even in Harsh Light
Backlit scenes — bright windows, parking lot lights, or direct sun — usually wash out the image. This camera's 120dB True WDR captures detail in both bright and dark areas simultaneously. You see faces, license plates, and objects clearly, not as silhouettes.
AI That Filters Out the Noise
Standard motion detection triggers alerts for everything — leaves, rain, animals, passing cars. AcuSense technology classifies humans and vehicles on the camera itself. You only get notified when a person or vehicle enters the scene. Fewer false alarms mean faster response to real threats.
Hear What Happens — No Extra Gear Needed
A built-in microphone picks up audio alongside the video feed. You can hear footsteps, voices, or glass breaking in real time. No need to buy or install a separate audio device. Combined with the alarm input/output (1/1), you can also connect external sensors or lights for a complete security setup.
Built Tough for Outdoor Installations
Rated IP67, this dome camera survives rain, dust, and snow. The IK10 vandal-resistant housing withstands impacts and tampering. Aluminum alloy construction handles temperatures from -30°C to 60°C. Flexible power options — 12V DC or PoE (802.3af) — make installation simple with a single cable.
