Outdoor 5G Wireless video transmission device (CPE)

Name: Outdoor 5G Wireless video transmission device (CPE)
Brand: Dahua
SKU: PFM881

Stock Code: PFM881

Builds a client link up to 3 km with its built-in antenna.

An 802.11 a/n link carries wireless traffic at 300 Mbps, and the 15 dBi built-in antenna forms a 40° horizontal and 15° vertical beam. The unit moves up to 40 Mbps over 3 km and mounts on masts 40 – 60 mm in diameter.

-30 – +70 °COperating Temperature

Key features

3km

Wireless coverage

The built-in antenna extends the client link up to 3 km.

40Mbps

Throughput at long range

The link carries up to 40 Mbps over a 3 km hop.

15kV

RF port ESD protection

The radio frequency port withstands ESD pulses at the 15 kV level.

15dBi

Built-in directional antenna

A 40° horizontal and 15° vertical beam aims the client at the base station.

Low consumption

The unit draws at most 8 W and takes power from a PoE adapter over one cable.

IN THE FIELD

Auto rangingThe device shows the straight-line distance between client and base station in real time.

Client priorityIt assigns a separate priority to each client in point-to-multipoint mode.

Status indicatorsWi-Fi, LAN, power and signal strength lights make alignment easier during installation.
