 Product Description

Alien ALR-F3700 Hydra RFID Reader

The ALR-F3700 Hydra RFID Reader is a novel UHF Passive RFID Reader solution designed to lower RFID implementation and running costs while enabling the realization quality read zones. Hydra readers combine a full-power 30dBm UHF reader, 8dBic antenna, a patent pending “Hydra” power, and data router technology. Each ALR-F3700 Hydra RFID Reader has two PoE ports allowing them to be daisy chained together into a “string” of reading points by simply connecting the PoE cable from one Hydra reader to the PoE port of the next reader. This enables very simple low-cost connectivity and minimal cabling costs.

Why buy this reader?

Hydra supports more complex network typologies for solutions where additional PoE power is needed or where there is a desire to build in more robustness. Examples include where there is a need to have a long network chain with power injected at different points down the network to extend the chain further.
