Smart H.265+ & Smart H.264+With advanced scene-adaptive rate control algorithm, Dahua smart encoding technology realizes the higher encoding efficiency than H.265 and H.264, provides high-quality video, and reduces the cost of storage and transmission.Two-way AudioWith its built-in high-sensitivity microphone and high-power speaker, the camera realizes two-way audio through the mobile app.Dual-antennaHigh-performance dual antenna and MIMO (multiple-input and multiple output) technology of the network camera make the WiFi transmission distance farther, anti-interference performance better, and video transmission smoother.Motion DetectionWhen moving objects appear in the monitoring image, Dahua Motion Detection technology triggers alarm or recordsDay/NightDahua Day/Night function provides color image when illumination is adequate; when illuminance is inadequate, it switches night mode and provides white and black image. It can guarantee that the network camera can work normally when illuminance changes.SpecificationImage Sensor1/3" CMOSMax.
