With automatic voltage identification function
Industrial grade, operating temperature -40~+70 degrees, protection class IP67
Charge for PWM pulse-width modulation
With MPPT function
With RS485 port, need to provide remote resolution protocol
Support MouduleBus protocol for data collection, data transmission support AT least MQTT(SSL), OPENSSL transmission protocol. The format of the data packet should include the start character, device ID, protocol ID, channel number, collection time, and CRC check code to facilitate the device to quickly access the platform.
The solar controller in the control box supports standard MouduleBus protocol and RS485 output.
Battery requirements
(1) The battery adopts high-performance, maintenance-free special colloidal battery, and the working voltage of a single battery is 12V.
(2) Battery selection of high performance maintenance free special colloidal battery, service life is more than 7 years. According to the power consumption of the monitoring system provided by the supplier, batteries in different installation positions should be backed up for more than three days.
(3) Batteries should be installed in thermal insulation battery boxes, which are buried in the ground. The buried depth of the battery boxes should be below the frozen soil layer, and the protection level should not be lower than IP67. Because the ground water level is high, the battery cannot be installed underground. Instead, it can be installed on the monitoring pole.

It has the function of remote network management for all devices, realizing the real-time monitoring of power status of front-end devices, power-off detection, remote restart of cameras, 4G traffic monitoring and other functions.
The control box should be equipped with sound and light alarm module, voice intercom and remote propaganda module.
Requirements for 4G routers:
When 4G mode is adopted for transmission, the camera should be equipped with a 4G router, which should support Wi-Fi function and full netcom function;
4G router should adopt industrial grade and be a well-known brand in China;
The router should support DC power supply mode;
The general pipe section adopts 4G ball machine, without router configuration.
The integrated control box shall adopt IP66 protection grade.
