• Gamintojas: Dahua
• Modelis: Dahua T4A-PV

The T4A-PV model from Dahua is a compact camera with a built-in WiFi module. This camera features a 2.8 mm fixed focal lens and a 1/3” CMOS sensor that operates at a resolution of 2560×1440 (4MPx).

The device also has built-in IR and white light LEDs with an operating range of up to 30m. It allows operation in 3 illuminator modes - IR only, white light only, or Smart mode - IR + white light. Furthermore, the device has BLC, HLC, DWDR, AWB, AGC, and 3D NR functions that adjust the camera's operation to the prevailing conditions and significantly improve image quality.

The camera housing is built to IP67 standards. The camera is powered by 12V DC.

The T4A-PV WiFi camera by Dahua has a double night mode - it allows you to record at night the image in shades of gray in infrared and in full color mode, using a white light illuminator. With this feature, you can easily recognize the colors of your intruder's clothes, even when they sneak in complete darkness. In addition to the deterrent function, the white light illuminator can also act as additional lighting for your property, activated by movement.

The Wifi T4A-PV dome camera has a intelligent motion detection algorithm, which can recognize the human figure. Thanks to this technology, the camera effectively reduces the number of false alarms caused by irrelevant objects (e.g. leaves of trees, insects).

In addition to precise detection of intruders, the camera can also effectively deter them - thanks to the built-in speaker and LED, the camera will effectively deter an unwanted guest when he enters the area protected by the camera.
