the emerging DIY home security market is one of the most interesting parts of the evolving smart home bringing home security options to people who felt priced out before one of your newest options is corner the off corner really is is a system that will keep track of motion at your doors and windows they aren't motion sensors they're actually accelerometers packed into these triangular tabs you'll stick them up on the corner of your doors and windows when things open they'll catch that movement and sound the alarm the siren comes from this kind of odd shaped base station you'll plug this into the back of your router and plug it into power it'll communicate with all the tags and when it senses motion when the system is armed will ring out the siren you'll use the corner app to arm and disarm your system and also keep tabs on things I wish they had some sort of accessory on your keychain or a keypad on the wall something else you could use to arm and disarm if you come and go for now you're forced to use your phone one problem though these don't keep track of when the door is open or closed like a regular contact sensor they only track when the door itself is moving that means that you can't open the app to see what's open to what's closed and also because it's an accelerometer if you open that door very slowly you can sneak by even when it's armed corner costs $98 for a three tag setup and you can add additional tags as needed it does have a yearly fee you get the first year for free but from then on it'll be 40 bucks a year that's only a couple dollars a month but still not as good a value maybe as a totally fee free options like eye smart alarm that kit might cost more up front but down the line you'll save money by not paying those fees for more check out the rest of our DIY security coverage at cnn.com here at the CNF smart home I'm right Chris
