Wireless 4G Video Transmitter Server


Product Description

HM4G supports multiple networks of LTE-TDD/LTE-FDD/WCDMA/EVDO/TDS-CDMA, Dual-card 4G wireless video server adopts multi-link bundling technology to support multi-channel wireless network module bundling, significantly enhancing wireless network transmission bandwidth. In the multi-way bundling, the multi-channel automatic balance coordinated transmission technology is carefully designed to maximize the transmission bandwidth and enhance the smoothness of video transmission. Products are widely used in public security, armed police, military, fire, road administration, urban management, sanitation, environment, public transport, passenger transport, electric power and other emergency command industries


Key Feature

1. Multi-link bundling technology is adopted to support 2-way 3G4G wireless network module bundling, which significantly enhances wireless network transmission bandwidth; transmission delay is small, average delay is less than 3 seconds; when bandwidth is extremely poor, delay can be manually adjusted to ensure video No frame loss

2. fficient H.264/AVC video compression encoding for easy low-bandwidth transmission of clear video; device supports video dual stream, low bit stream for wireless transmission, high bit stream for high quality front-end recording

3. The device supports two modes of video and picture.

4. Multiple ways to save traffic

1) Support for timing work, SMS sleep and wake-up functions

2) Manager manually controls video transmission or not

3) Under normal status video server does not transmit video data (only a small amount of heartbeat data is transmitted), and the video data is transmitted when a client requests to watch a video or an alarm signal is triggered.

5. Dedicated DSP solution, embedded structure design, small volume, high integration, high reliability, high anti-drop and anti-shock performance.

6. Low power consumption, dual card 4G video server average power is less than 5W.

7.Bidirectional audio transmission, support for both line-in and passive (mic) audio capture inputs. The sound effect is good, the average delay is less than 3s and the video is synchronized (the difference between the video and the video is less than 50ms), and the downlink sound delay is less than 50ms.

8. Built-in hardware dog, abnormal automatic recovery, automatic connection after network interruption, to ensure stable and reliable system operation

9. The device supports the routing Internet function and can provide users with routing gateways, DMZ, VPN and other functions.

10. Support WIFI connection, with dual working mode selection: access wireless AP gateway mode and peer-to-peer network mode (AdHoc) can realize wireless connection configuration parameters, transmit video and download video recording. (This function is optional)

11. Support GPS, GPS data standards support access to a variety of platforms. Support GPS video overlay. (This function is optional)
