The Dahua IPC-HFW1431T-ZS-S4 camera is equipped with a 1/3" 4Mpx Progressive Scan CMOS sensor, thanks to which the camera generates images with a maximum resolution of 2688x1520 pixels (4Mpx). To obtain better recording quality, the camera has many solutions to improve the visibility of the scene, such as WDR 120dB, 3DNR. The used motorized lens with a focal range of 2.8-12mm provides a wide range of possibilities in terms of adjusting the viewing area. The infrared illuminator with a range of up to 50m allows the camera to be used at night. The camera's advantages include a built-in microSD card port (up to 256 GB) and IP67 protection class allowing the camera to be used in difficult environmental conditions. Dahua Entry - is an innovative series of Dahua devices, enabling the use of the latest technical achievements in modern monitoring installations while maintaining an affordable price without compromising on quality.

The app allows remote control of devices (IP cameras, IP video intercoms, DVRs, and NVRs), simultaneous image viewing of up to 4 channels, remote PTZ control (speed dome cameras), audio control, and snapshots. Furthermore, the app allows you to add device lists and favorite channels, remotely play back recordings, and features "PushAlarm" and eMAP alarm event notifications. Power over Ethernet (PoE) is a solution designed for quick and easy installation of network devices, convenient equipment operation, and easy system upgrades. Support for PoE in the 802.3af standard allows you to connect an IP camera using popular twisted-pair UTP cables. Saving the total number of cables required to run the device streamlines the monitoring system and allows the camera to be located away from traditional mains power sources.
