The SED-2120 is a high resolution, Ethernet (LAN and WAN) ready digital video transmission device. It is specially designed to meet the increasing need for high quality, high reliability, real-time video streaming used in the field of surveillance and security. The SED-2120 is based on Arm9 SoC, MPEG-4 ASP compliant compression technology to compress the video stream and transmit them via LAN and WAN. It supports automatic/manual frame rate control for concurrent video stream accessing in different bandwidth. The SED-2120 also provides RS-232 or RS-422 or RS-485 and digital I/O data transmission over Ethernet for product integrators or solution providers. With this system, users can build digital remote surveillance systems easily.

ACTi's IP devices provide two RJ-45 connectors. One is WAN and one is LAN. Both of them are 10/100. The difference between a WAN and a LAN is that WAN is to be connected to the internet, while LAN is to be connected to a local network. Since the internet's bandwidth is very critical, ACTi provides hardware QoS (Quality of Service) on the WAN port to ensure the bandwidth when uploading video streams through the internet. Also, the WAN port is equipped with PPPoE (Point-to-Point Protocol over Ethernet) which enables the IP camera to be connected to an ADSL or cable modem without the need to go through a router first. If the IP cameras are to be deployed at a large area, it will be very costly to provide routers to each IP camera. Using IP cameras with PPPoE built-in, installers will be able to save a lot of cost over routers.
