The same functions are basically the same, and the market requires to retain the existing functions of the NVR. ② Adjust the main menu. AI setting and AI search are put together with a separate AI menu items, other events are in the alarm item, and the main and auxiliary screens are set to the right-click menu. ③ Supports vector font. ④ Web interface style is consistent with the local menu. Network Security Baseline V2.0 ① Supports system firmware encryption. ② The device supports 802.1x access authentication. ③ TFTP upgrade: The trusted upgrade and secure boot via Uboot. ④ Supports network security requirements such as firewall. Support web no plugin ① Version requirements: For chrome version number lower than 42, Firefox version lower than 52, there is a plug-in. For the browser higher than the above versions, there is no plug-in. ② Supported contents are mainly based on video. Onvif optimization ① Supports onvif18.06 tool. ② Supports profile G. International requirements ① Adds Shut down button before initialization. ② Adds the country, language, and format settings. ③ Supports synchronizing audio, format, and time zone to the front-end device when connecting to it. Automatic H265 ① Automatic setting front-end adopts H265. encoding when registering remote device to the NVR. Email optimization ① Adds IPC channel name in the body contents of the alarm email. ② Standardizes intelligent event email format. Auto registration ① The whole series supports the auto registration function suitable to connect to all platforms. ② Auto registration via domain name. Alarm Center Dual IP ① Supports server of dual-IP. ② Supports to upload alarm information to 2 server addresses at the same time. Hard disk health plan ① Supports hard disk health detection. ② Supports manual detection refresh. ③ Supports to display detection details report. ④ Supports alarm prompt for detected errors. Right now it supports hard disk temperature too high, linkage abnormality, imminent error, vibration, etc. Raid optimization ① On RAID interface, cut disk array enclosure item. (it was never supported before) ② Raid creation and deletion process are in the background. ③ Adds the working mode of the raid hard disk. Hard disk estimation ① Adds hard disk estimation function. ② Supports the hard disk storage capacity estimation based on the resolution stream of the current access channel. Hard disk migration ① Hard disk migration formatting strategy, adding "unformatted" status. FTP experience optimization ① Supports FTP storage pictures based on channels. Hard disk light ① When the hard disk is abnormal, the indicator light is on. When it is normal, the indicator light is off. ② The HDD abnormal event does not affect hard disk light. Thermal Imaging ① Supports thermal temperature measurement. ② Supports thermal imaging to trigger sound and light alarm. ③ Support thermal imaging dual-sensor device and synchronization storage. POS ① Adds an independent POS item in main menu. ② Supports POS configuration and POS search. Intelligent Speed Dome ① Unified Intelligent IPC and smart speed dome protocol. ② Supports smart speed dome IVS. ③ Supports smart speed dome people counting. ④ Supports smart speed dome heat map. ⑤ Supports smart speed dome metadata. AI by camera image matting ① Once the connected channel has no matting image, the NVR can realize image matting based on the coordination. ② Supports image matting in preview mode. ③ For smart types such as perimeter protection and license plates, supports image matting in preview mode. ④ Right now, does not support image matting storage. ⑤ Supports detected plate image matting during playback. The 2nd panoramic+ PTZ camera ① Adds people distribution display. ② Right now, does not support people distribution display during playback. ③ Enable/disable crowd density display via Web function is for the 2nd panoramic+ PTZ camera only. AI Fisheye ① Supports queue management. ② For abnormal queue number and the queue stay time, these two events adopt the same linkage configuration. AI Linkage snapshot ① For AI event, there is picture storage function instead of snapshot. ② For AI events, the back-end analytics realizes the image matting and the large image and matting image will be sent with the event when the client subscribes. ③ Cannot configure to trigger other channels. National information code ① ITC reports a 3-digit code table. The NVR currently only maintains a 2-bit table. The NVR needs to maintain 2-bit and 3-digit codes. Binocular passenger flow statistics ① Fixed bug: Supports regional people counting. ② Support configuration and report search. Password resetting ① Adjust reserved mailbox item: From the admin user configuration interface to Reset Password page of the security center. ② At the same time, security question and reserved mailbox item are merged onto the Reset Password interface. recover password ① Adjust the QR code of the device's local GUI, and the QR marks as local GUI. ② For the storage device, user can only scan the local QR code to reset password. Delete scanning QR code on Web to reset password. Do not support reset password via configtool. Supports reset password via DMSS. . ③ Log: password reset operation log type is security management. MAC address binding ① Supports setting the MAC address for newly added users, and only allows access to users through specific MAC devices.
