In recent years, SimpliSafe has become synonymous with DIY home security. It's also known for offering one of the most affordable monitored security systems you can get.
For a limited time, it's even more affordable: You can save 15% on any SimpliSafe system and get a free camera. The latter is worth $99 all by itself.
What's nice about SimpliSafe is that you can choose from a variety of bundles -- each consisting of various types and numbers of sensors -- or build your own based on what you need. From there you can easily expand the system.
At a bare minimum, you'll need the SimpliSafe Base Station and Wireless Keypad, which together cost $185. Alternately, you can start with the Foundation Package ($195.47 after discount), which includes those two items, an entry sensor and a motion sensor.
Next, choose a monitoring package, which is based on a cellular connection -- meaning no landline or Wi-Fi required. These run 50 cents per day for Standard monitoring or 83 cents for the much more robust Interactive option.
