Functionally a Link and Gateway device perform the same job - the only difference between the two is:
Link devices have a cellular modem and can use 4G, Wi-Fi or LAN to connect to the internet.
Gateway devices have NO cellular modem and can Wi-Fi or LAN to connect to the internet.
The device acts as bridge between your IP camera(s) and the cloud service. Most IP cameras will transmit a compressed video stream using an H.264 video codec that will use between 3-10 mbit/s - a high data rate that is costly to use in remote location.
Your device fixes this problem by transcoding the video to EdgeVis which uses considerably less bandwidth - by default 200 kbit/s for 4G connections and 400 kbit/s for LAN/Wi-Fi. This vastly reduces data costs and contention with other data services, and ensures near-instant live view of a remote camera regardless of how low-bandwidth the connection is.
The incoming video from cameras can also be analysed for motion detection and configured to detect people or vehicles, and notify users with a short video clip of what triggered scene.
You device will also record the incoming video at the original quality on its recording disk - and offers a cloud backup service (at the original quality) for user-specified specific incidents.
Link-1 and Gateway-1 devices are capable of recording, video analysing, and live streaming one IP camera.
Link-8 and Gateway-8 devices are cable of recording and video analysing eight IP cameras, and live streaming one video stream (which can either be one camera, or four cameras in a quad-view).
