PFM880-M
Outdoor 2.4G/5G Wireless video transmission device
>Support proprietary protocol TDMA; when the wireless devices open TDMA, other manufacturers will not be able to link them which ensure the system safety;
>TDMA protocol overcomes the inherent hidden nodes problem of 802.11, and makes the wireless products have the better performance in long-distance and point to multi-point;
>2.4G: Working frequency support 2312～2732MHz;
>5G: Working frequency support 5745~5825MHz (extended range: 4920~6100MHz);
>Support auto ranging function, real time display straight line distance between client and base station;
>Support flow control, effectively control base station/client input/output flow control;
>Support VLAN partition, realize virtual local network function, control broadcast storm;
>Support Web page and AC remote operations management and make the installation and maintenance be more convenient;
>POE power supply, which supports international standard 802.3at and lets power supply be convenient and reliable;
>Built-in professional lightning protection technology, which supports 6 kV port lightning protection ability to ensure that the poor working environment adaptability of outdoor and greatly reducing rate of lightning damage to equipment.
