			Rex Plus ED-50 has four settings: an alert sound of an angry and protective watchdog; soothing sounds to signal a guest's arrival; continual tranquil sounds of the rainforest; and alert sounds of both the angry watchdog and a warning siren. It plugs into any standard electrical outlet and features variable-distance sensitivity up to 30 feet. The closer the intruder gets, the more frequent the barking. As the intruder backs off, the barking decreases, stopping completely when movement is out of range.
