In a smaller space, the last thing you want to be bogged down with is an extensive security system. Nest Secure will blend right into your space. Hi Caytlin, I’m sorry to hear that you’ve been burglarized!If you’re looking to self monitor, SimpliSafe is not a good choice as you won’t be able to livestream footage, receive notifications, or control your system remotely. Since your Internet connection isn’t great you should definitely look for a system with cellular or landline backup. I’d look into abode. Their Connect Plan is only $10 a month or $96 a year and it will give you cellular backup and unlimited self monitoring. Here’s a link to my review of their starter kit w61s9Our primary concern is that we have 3 levels; The front entrance is on the ground floor in our bedroom is on the third floor. When we’re in the bedroom between the white noise machine in the central air system we would never be able to hear anything happening on the first/ground floor. We’re looking for an economical, DIY security system with a loud alarm/siren to alert us when were sleeping And to alert us if there is an intruder when we’re not home. We’d love your input/ recommendations!Would also love your thoughts/advice on self monitoring vs using a security company to monitor. Many thanks!KelliHi Kelli, You’re very welcome and thanks for reading!There are a bunch of different companies that have sirens I recommend SimpliSafe.
