T-Link TL250 Internet alarm communicators create fully supervised security solutions between protected premises and central monitoring stations. The simple-to-install modules save end-users money by taking advantage of their existing networks to provide secure Internet communications over a private network (LAN/WAN) or the Internet, between the control panel and the Sur-Gard System ll/III central station receivers. This method provides flexibility and an always-on, two-way line of communication. The TL250 communication stream is small and requires only a limited amount of network bandwidth. This ensures that the integrity of the data being transferred never becomes compromised. To reduce security risks, the TL250 utilizes industry-leading, 128-bit AES encryption, polling and hardware substitution protection.
