One of the selling points of the Life Shield security system was the idea that all the equipment can be operated on a wireless system so we wouldn’t have to wire everything up. Sounds great, right? It would be, if it worked. Every one of my outdoor cameras quit operating in wireless mode, and the “fix” Life Shield gave me was to hard wire them to the system. That’s exactly what we’d been trying to avoid by making the conscious decision to go with a wireless system.
