The DSC 3G8055AT is a defunct AT&T 3G Communicator for a DSC Impassa Security System, Apart from the DSC Impassa being a relatively outdated security system that you should consider replacing if you own one, the DSC 3G8055AT is a 3G communicator, and it can no longer be activated for monitoring service. Additionally, any 3G8055AT unit that is currently activated will stop working once AT&T shuts down their 3G network. That is why there is a big scramble for users to upgrade to the LTE communicators, as those modules will be supported for a very long time. But we can't really recommend the DSC 3G8055AT, as it is an outdated communicator for an older security system. We only give the product a 3-Star rating.

There are some positive aspects for the DSC 3G8055AT. As a cellular communicator ir provides reliable connectivity, which is very important for trustworthy alarm monitoring service. And when active, it can connect with the Alarm.com platform so that you can control your system remotely. This is assuming that access to Alarm.com is included in your monitoring plan. But there are also some major downsides for the DSC 3G8055AT. As we mentioned earlier, the communicator cannot be activated for monitoring service due to the AT&T 3G Sunset. And once the network is shut down, the communicator will stop working entirely. There is also the consideration that the communicator must be installed inside the panel. But really, you wouldn't bother doing this anymore, as the communicator can no longer be activated. Another downside is that this communicator is cellular only, and it does not offer internet connectivity. While the DSC 3G8055AT was once a good communicator option, that is no longer the case. We give it a 3-Star rating.

Good: Reliable Connectivity, Alarm.com.

Bad: Cannot Be Activated, Will Stop Working w/ Network Shutdown, Requires Installation, No IP Connectivity

Bottom Line: 3 Stars
