>This radar system is ideal for protecting larger properties, with its range of up to half a mile and adjustable detection zone. It’s old school: With no Wi-Fi or app needed, you simply turn on the receiver and pair the detector. It then sounds an alarm whenever a person or animal moves into the area

This doesn't sound that useful without a camera unless you're using it in an indoor space where you know animals aren't going to trip it. Otherwise, what do you do when you get an alert at 3am and you don't know if it's a racoon or a burglar?
