The next innovation in doorbell cameras is . . . devices that are armed to shoot.  There’s a Kickstarter on the way for “PaintCam Eve,” which “shoots” paintballs and cartridges of tear gas.  Here’s the  commercial they created on a Kickstarter campaign.       It’s a smart device with facial recognition . . . and the paintball-firing can be triggered by you as you’re watching on the app . . . or it can be automated.   And it doesn’t just shoot paintball pellets, it can also be loaded with cartridges that can unleash TEAR GAS.   PaintCam Eve is from a start-up out of Slovenia, and there’s no word how much it’ll cost, or what the upkeep fees would be to keep it loaded.  Would you buy one?
