Good quality voice intercom can be achieved within the Bluetooth distance acceptance range, and external Bluetooth audio can be connected to achieve broadcasting function< br /> Positioning function: The positioning module is built-in to the antenna, without the need for external antennas. It has AGPS assisted positioning to achieve rapid positioning and remotely obtain the geographic location information of the device< br /> Display function: Equipped with a built-in OLED high brightness display screen, the displayed content can be clearly seen under strong light. The device has an OLED screen, which can display 4G, WiFi, Bluetooth, GPS connection status, signal strength, and display the platform's connection status, making it easy to install and debug< br /> Intercom function: The audio protocol supports audio protocols such as G.726, and supports bidirectional voice intercom. In addition to calling the center or being called by the center, there is also a PTT cluster intercom function, which is convenient for any communication within a group< br /> Camera parameters: using 1/2.8" Sony CMOS 30x 1080P SONY 200W star level sensor high-definition integrated movement, illumination: F1.6 (W), 50 IRE, IR-CUT on 0.05 lx (1/30s), IR-CUT off 0.005 lx (1/4s). Optical zoom 20 times, digital zoom 10 times, infrared night vision distance not less than 100 meters, built-in photosensitive sensor, night vision function automatic switching, to ensure that real color images can be captured in areas with poor lighting at night< br /> Pan tilt control: horizontal angle 360° Continuous rotation in all directions, vertical angle -15°~ 90°， Support local and remote pan tilt control< br /> Battery capacity: Built in UPS battery, continuous working time not less than 10 hours, voltage 14.8V, battery capacity 12000mAh (185Wh), daytime power consumption: 10.45Wh, nighttime power consumption: 17.1Wh, expandable external battery pack< br /> Portable: The device is designed with a magnetic composite suction cup, and the specialized protective box equipment is installed using a tripod bracket. Alternatively, the built-in magnet of the control ball can be used for adsorption installation, making it easy to build and disassemble. Temporary control is more convenient, and can also be deployed and installed on the roof and bracket< br /> Structural design: Fully integrated with built-in antennas (4G, Bluetooth, GPS/BD), eliminating the hassle of external antennas and meeting the needs of wireless video emergency command to quickly build and control< br /> Software function: The PC software has a client with C/S structure, as well as a WEB web client with B/S structure, supporting mobile terminal monitoring software such as Apple and Android< br /> Compatibility: It can seamlessly access the 28181 video management platform, and the command center can dispatch device images, two-way intercoms, video parameter settings, and operate pan tilt operations through the command video terminal. Control ball, cruise function: call up preset point 99, turn 1 and a half circles
Network adaptability: It supports encoding and transmission in various network modes such as the Internet, local area network, private network, satellite, and 3G/4G. The device should support intelligent dynamic bit rate adjustment and be able to automatically adjust the image frame rate and bit rate in case of poor bandwidth, ensuring the smoothness of the image. The network transmission can achieve stable transmission of 1080P 30fps images at a bandwidth of 1.5M, and the voice intercom delay is less than 1.5 seconds< br /> Working environment: protection level IP66; Working temperature -20~60°; Working humidity 0-90%, no condensation< br /> Standard accessories: 1PCS safety protection box; 1 PCS of composite interface line for aviation head; Tripod 1 PCS; Camera magnetic suction fixed disc 1 PCS; Bluetooth handle 1 PCS; Optional: Car charger, Bluetooth earphones, wired handle
