This device is compatible with all transmitters and receivers in the Dakota 3000 Series, and also has a range of up to 600 feet*. This device uses a passive infrared detector to monitor an area up to 100 degrees wide (which can be brought down to 20 degrees, or any degree in between if necessary). This along with the sensitivity control panel (switch from monitoring between 12, 25 or 40 feet away) allow you to control the precise area you want monitored. This device is powered by a single 9V battery that lasts between 6 and 12 months depending on how much it is used. You'll also never be unsure of whether or not this device is nearing low battery power as there is a low battery alert built into the device to notify you when it is time to replace the battery.
