We found that a lot more convenient than racing inside to beat the alarm’s 30 second window, particularly if you have an armful of groceries or a baby on your hip. The SimpliSafe system requires a professional monitoring subscription to receive alerts. That’s because it relies on a cellular connection
rather than internet, so someone needs to send you an SMS text. There’s no option to receive automatic in app alerts. This also means your DIY security system is essentially a local alarm — meaning if a burglar breaks in, your alarm will
activate, but the police won’t be alerted. You’ll have to pay for one of the professional monitoring plans to save yourself the task of keeping a constant eye on the video feed.
