Spouse purchased the Atlas system the so called "top of the line" system for Christmas. Details on it were scarce on the website. No issue with the 5-1 sensor itself it seems fine. Peripherals are another matter. The High Definition touch screen display is nearly useless. It has no battery backup so if you unplug it or have power outage you have to reconnect the sensor. It does not connect with anything (it does have a USB plug but does not connect to PC) Bluetooth or wireless. You have to purchase another unit the Access module to connect to anything else. So the monitor is a single use electronic box that has no connectivity to anything except the sensor. Who builds something like that today?
