Dahua NVR4232-EI

SKU / EAN: 6923172584304

The device supports Smart H.265+, H.265, Smart H.264+, H.264, and MJPEG video decoding, providing a maximum throughput of up to 256 Mbps for input, recording, and output.

With the ability to decode video at resolutions up to 16 MP, the NVR4232-EI is ideal for use with modern IP cameras. Key features include AI by Recorder support, which enables facial detection and recognition, perimeter protection, and scene analysis (SMD), as well as AI by Camera support, which offers additional features such as people counting, stereoscopic analysis, and heat mapping.

The recorder supports EPTZ technology and single-key arming and disarming. The NVR4232-EI is equipped with an industrial-strength processor and runs on the Embedded Linux operating system, with a user interface accessible via a web browser or local GUI. The device offers advanced video analytics capabilities, including face detection (with attributes such as gender, age, glasses, facial expressions, masks, and beards), facial recognition with a database of up to 10 records and 20,000 images, and perimeter protection.

Additionally, it supports SMD Plus, reducing false alarms due to weather conditions. The NVR4232-EI has 32 audio channels, supports various video resolutions, and offers flexible multi-screen display options.

The device is compatible with cameras from other manufacturers thanks to support for ONVIF and other standards. The recorder offers general, motion detection, intelligent, and alarm recording modes, with the option of saving to USB or network storage devices.

The NVR4232-EI includes HDMI and VGA ports for video output, audio and alarm interfaces, and two SATA ports for connecting hard drives with capacities up to 20 TB. The device is characterized by low power consumption (<10 W without HDD) and a wide operating temperature range (-10°C to +55°C).

Dahua NVR4232-EI is a comprehensive solution for surveillance systems, combining high performance with advanced image analysis functions.
