(1) Door sensor-transmitter without any battery
Model DA4TAC is an “extra” motion sensor, for doors or entrys that are open or closed, with the added feature of being able to use power supply for those locations with high traffic, to eliminate battery replacement. The motion sensor / transmitter includes an AC transformer with 6′ of cord that simply plugs into a 110v AC electrical outlet. If your location has an electrical outlet near the entrance or area of protection, then the DA4TAC is the ideal unit for never having to change a battery and always having the alerting notification you desire.
The Model DA4TAC has all the exclusive designs of the best motion sensor alerting system available, the Model DA4D and also, no more battery changes.
