可根据实际需要定制MINI手提箱带显示功能 Portable receiving box dual antenna interface, audio and video interface can be customized according to actual needs MINI suitcase with display function


LA-6900ZF is a brand new digital relay device. Compared with traditional analog relay devices, it adopts COFDM modulation and transmission technology, and the forwarding power reaches 5W. Under the condition of no occlusion, the forwarding distance can be up to 10 kilometers. The radio frequency adopts low-frequency (500 ~ 600MHZ) COFDM digital transmission technology to ensure that the device has good anti-interference ability during transmission, and has good performance in distance and video effects. and. The device adopts die-casting appearance, good heat dissipation, small size and easy to carry. The front-end wireless transmission can choose 1.2G or 2.4G traditional wireless analog transmission equipment. The LA-6900ZF receiver is exquisite and compact, uses 12V power supply, and has low power consumption. It can be powered by traditional lithium battery packs. It is very suitable for use in criminal investigation, investigation and evidence collection, public security, fire protection, court, and security work.


After practical application by a large number of customers, under the same environment, LA-6900ZF has a longer transmission distance than high-power analog forwarding equipment, and the video image is more stable. In various environments with strong interference, the transmission image is also very stable and clear. At the same time, it is small in size and low in power consumption. Under the same power, it can work longer and work stably for a long time.


Remarks:

The receiver configured by LA-6900ZF is a standard 1U chassis rack receiver or a MINI suitcase receiver. If the customer needs to watch the video directly on the MINI suitcase, special customization is required. Please specify in detail before ordering.
