Dahua's third generation network video recorder embedded Wi-Fi module to support wireless AP function, support automatic detection and connection of IP camera from Dahua without any operation. In addition, it has two-antenna for a strong wireless network signal. IEEE 802.11 b/g/n (2.4G Hz) Wi-Fi covers wider and further area. Also, this NVR can support wire IP cameras accessing, making the installation more flexible. Without the limitation of the network cable, this NVR is ideal for a wide range of applicaiton such as home safety, cafe, retail, grocery, education and other industries. Combination with Dahua wireless camera makes the perfect solution for surveillance systems that work independently of video management system (VMS). It features an open architecture that supports for multi-user access and is compatible with ONVIF 2.4 protocol, enabling interoperability with IP cameras.
