That is why I'm going to unplug the unit when I'm home. Don't want to open myself for someone hacking in. I even cover the cameras on computer and xbox with black tape.
Also to save on electricity. I noticed when I unplug the xbox when not in use, I save $20 a month on electricity.
Game consoles, smart TVs & disc players, DVRs -- any appliance that's connected to a network, WiFi or cable TV port is probably eating electricity. They are called "Vampire Loads", because they are sucking the money out of your pockets.
Smart power strips and smart UPS devices have a Master plug outlet that disables the switched outlets. If you have your TV plugged into the master outlet, when it's off, the switched devices' outlets are disabled. It's one solution to avoiding the Vampire loads, but the simplest is to use a power strip with a switch you can turn off when no one is using those devices. I have about 4 Smart Strips in use. Hawaii Energy runs deals now and then where you can get a Smart Strip and LED bulbs for a super cheap price.

You use a smart App on your phone or tablet to control and view the energy usage. There's also a model that reads IR pulses from remotes. If there's been no remote pulse in a set time period, it powers everything off.

Home invasion, guest breaks something, dog bites a guest, car crashes into the living room ... You'll be saying, "Man, if only my cameras were on, I'd have that on video!"
Something to consider.
