3. Equipment remote management, configuration, diagnosis
The configuration of the device can be as follows:
1, LAN search configuration tool: need a computer / notebook, through the device-specific network cable we provide to connect with the device (PC directly connected to the device or through the switch / HUB network), run our LAN configuration tool software (sacdil_pc. Exe), this is mainly used for initial configuration when the device is shipped from the factory or after the device fails, bring the notebook bag to the site for maintenance;
2, device host UI: device connected to a display, a USB mouse / or infrared remote control, local configuration of the device; can be used for fast configuration anytime, anywhere;
3. Device networking, after accessing the SmartEye network video integrated service platform on the public network, remote configuration can be performed through the SmartEye client/manager; of course, the premise of this is that the device must be networked, for example, the 3G4G card has no arrears, and there is a signal. Power (such as solar power supply is sufficient); through the smarteye manager, all devices can achieve remote configuration, remote viewing status, remote diagnostic remote upgrade, and can support SMS query device status / SMS diagnostic device failure, SMS to configure the device, The SMS remote control device restarts, and the SMS triggers the device to go online and offline.

(2) Server recording/NRU: This requires device networking, which can automatically upload the video to the SERVER without the user viewing the video, and save the video to the SERVER hard disk in the SERVER/NRU, and pass the monitor later. Video remote retrieval - platform storage for retrieval and download playback;
Note: If you go to 3G mode, if you use it, the user can't see the video. If you don't feel it at all, the MDVR device automatically uploads the video to the SERVER/NRU video by 3G traffic, which is a large amount of 3G traffic charges.
(3) Client recording: After opening the video of the device, the client can save the audio and video recorded on the network to the hard disk of the local PC;

9. Alarm linkage
The alarm linkage is when the alarm event occurs, causing the related equipment other than the alarm device to operate. When an event triggers an alarm in the device, a series of action responses are sent to the platform. For example, when we set a certain alarm input, set the alarm output to set the “start recording” action, and configure the corresponding channel, pre-recorded and extended recording time. When an alarm source triggers the event, the device will store the video containing the alarm recording according to the setting “Start Recording” and report it to the platform alarm information (can be queried from Manager -> Alarm Linkage Management). As shown below:

17. Open SDK-platform docking fusion
Support WINDOWS and LINUX/UNIX systems, provide C/S and B/S WEB SDK, and quickly integrate with various industry business system platforms.
It is the customer to install the smarteye mode on the PC, this is called C / S mode; and many customers will also ask the WEB way to access, that is, do not install the software, use the browser to enter the server IP / port to watch the video, This is called B/S mode; we do not provide commercial B/S software;
We provide B/S secondary development kit, WEBSDK, for integration and secondary development for customers, that is, through their original B/S platform, they can directly call the video of our device. Usually, B/ S-visited customers, they usually have their own set of WEB platforms, such as water-based flood control command / smart agriculture, they all have WEB platform, can remotely collect and view the sensor data on the spot, that is, no video, then pass We provide WEBSDK, they can increase the ability of live video access on the original pure data platform.
WEB SDK We provide SDKs with three different mechanisms for integration with different original business systems:
1) OCX control form, this is the simplest, most commonly used, but only limited to the IE kernel browser, that is, pick the browser;
2) HLS-based browser-independent WEB SDK, does not pick the browser, but will bring an additional network delay of about 8s;
3) RTMP-based website FLASH live broadcast mode, does not pick the browser, but compared to OCX and C / S software, will increase the network delay of 1-2 seconds;
4) H5-based streaming media
For example, a local city traffic police team newly launched a mobile video law enforcement project, the original WEB form B/S business system can quickly integrate the new mobile video subsystem by integrating the smarteye client SDK.

X. About the security of the system
Hefei Youshi Technology's 4G image transmission equipment and back-end SmartEye platform system provide high security, multi-level user name/password protection authentication mechanism, self-developed embedded system software, encrypted transmission mode and other measures to ensure system security. Not infringed. Specifically embodied in the following aspects:
(1) Wireless communication network mode: The audio and video acquisition equipment (signal acquisition terminal) of this platform adopts 3G data network, and the client (such as mobile commander notebook display, handheld 3G intelligent terminal equipment of relevant personnel) adopts Ethernet network or 3G data network. .
Because 3G has better network coverage, larger network bandwidth, and GPS positioning function, it is more suitable for the network mode used when moving objects collect signals. Moving objects include people or vehicles, and collecting mobile audio and video signals through 3G. ;
(2) Network access security settings: device security access adopts “authentication mode”; viewing media source adopts “authentication or authorization mode”; background management adopts “authentication and rights management mode”; recording file adopts “encryption mode” Device access uses "authentication or authorization"; streaming server uses "self-secure mechanism."
Multi-level username and password authentication mechanism
Hefei's wireless network video server and back-end platform system, the communication connection between each other is protected by user name and password. The "front-end device", "central server", and "user client" are all connected through the network.
Large-scale network video integrated business management platform SmartEye
“User” login “front-end device”, “center” login “front-end device”, and “user” login “center” all require user name and password. These user name and password mechanism are the most basic and most reliable measures for system security. one.
Wireless channel encryption transmission protocol
Vision Technology's 4G individual law enforcement products use a proprietary encryption protocol to encrypt and transmit the transmitted audio and video data. The non-standard encryption algorithm ensures that the system is not easily cracked and recognized by common software.
In addition, the user name and password of the back-end platform login are transmitted on the public network. If it is a clear code transmission, the possibility of being stolen is very large. Any user name and password of the SmartEye system are encrypted on the network. Even if it is stolen, it cannot be cracked.
Support hardware dongle
Support USB hardware dongle, support advanced encryption algorithms such as DES/3DES/AES/MAC, support ISO7816, support data encryption, decryption, MAC operation and key decentralization and dynamic key encryption, client and server double verification This makes the security of the software system greatly improved.
Unique network transmission protocol
When the video digital stream is packaged and sent to the IP network in the video server, the packaged format and the compressed encoding format of the streaming media are unique. Only proprietary decoding software can solve normal images, otherwise it is just garbled.
