Do you need Instant Notification when Motion is Detected, or when Customers enter your Office or Store?

The DA50L-A, or the Rodann TX/RX-1000A is a long range, wireless, entrance alert product that uses a PIR based transmitter and plug-in receiver.  This is our best selling, flagship product at 1800doorbell.com. This is one of the best entrance alerts we offer. The entry alarm has been used to alert store owners when a customer enters a store, alert homeowners when kids open the basement door, or notify offices and warehouses when a stock room door has been opened. The DA50L-A Wireless Door Chime Set is a high-quality passive infrared (PIR) door chime that detects infrared waves whenever something crosses its path. Because it does not use light beam projectors or reflectors, the DA50L-A is resistant to false alarms triggered by light. Works with both open or closed doors. The DA50L-A Wireless Door Chime is battery operated – no wiring required. It is perfect for both personal use in the home as well as commercial use in warehouses or other commercial settings.
