The DSC SCW457AMVZ consists of a DSC Impassa Security System with an added Verizon CDMA Communicator and an image sensor module. There isn't actually an image sensor included with this system. You just get the module needed for supporting an image sensor. Unfortunately, there isn't a lot to like about this system. The Impassa is a relatively difficult system for DIYers to work with, and the CDMA Communicator can no longer be activated for monitoring service. For that reason, this product has been discontinued. We do not recommend the Impassa System in general, and give this product a 2 Star rating out of 5.

There are some positive aspects to the DSC SCW457AMVZ. The included panel can still technically be used for monitoring service, but you would need to replace the CDMA Communicator with an LTE Communicator instead. Many Impassa Systems are still frequently used, despite it being an older security system. This goes to show that it is built to last. We also appreciate the fact that the Impassa supports local end user programming. The same cannot be said for the newer DSC Wireless System, the DSC Iotega.

But the downsides to the DSC SCW457AMVZ are very apparent. The communicator can no longer be activated, per Alarm.com requirements. If you have an Impassa with a CDMA Communicator that has already been activated, then it will continue to work until Verizon shuts down their CDMA Network in the coming years. The image sensor module for the system is spotty at best, as image sensor technology really wasn't quite there yet when this system was released. The system is difficult to program for DIYers, and there are certainly easier systems available. All of this leads to us giving the DSC SCW457AMVZ a 2 Star rating.

Good: Panel Can Still Be Used, Long-Lasting, Local End User Programming

Bad: Communicator Cannot Be Activated, CDMA Network Being Shutdown, Poor Image Sensor Module, Difficult to Program

Bottom Line: 2 Stars
