The GW4 Wireless Gateway is our advanced GW3 gateway with an external antenna providing additional range and signal stability. It features 32GB of on-board memory for data storage and it provides interconnectivity for an unlimited number of Halo/S™ devices at once.

One gateway is required for each site, and oversees each wireless network. It also relays communications between all wireless sensors and a connected PC or local network. On-board storage is used to store decades of logged data from the connected sensors in its wireless network. The gateway can be optionally configured to work with our HaloCloud service, allowing remote monitoring, control, and alarms for the entire system.
