#1SimpliSafe

SimpliSafe

Pros

  • Livestream video on app
  • Support for Alexa and Google Assistant 
  • Great voice control response
  • Quick DIY setup

Cons

  • Cameras stop working below 20 degrees F°
  • Not compatible with Apple's HomeKit

One of the cheapest home security system choices, SimpliSafe an excellent option for many homeowners looking to secure a property, without buying extraneous features that allow a system to connect with dozens of home devices and electronics. In addition, as the DIY setup here is among the easiest available, you can also save some cash by doing the installation yourself. There is a wide variety of security equipment available for all of your needs including security cams, battery-powered motion detection sensors, panic buttons and much more. Should you feel uncomfortable tackling the installation yourself, there are also competitively priced professional installation options as well.

Because each of the SimpliSafe sensors comes with pre-applied sticky tabs on detachable backs, you can easily and quickly peel and stick the device where you want it to go and then proceed to the next sensor. The system is wireless, which means no cutting and reattaching wires and no need to try and hide the equipment. Whenever you need to move or relocate sensors, simply detach them from their backings, and then release the sticky tabs. This means no damage to the walls or windows, making it a solid choice for renters and property owners alike. After you've placed all of your sensors, cameras, or other accessories, the only remaining installation task is to plug the base station into a nearby electrical outlet.

You'll then select pairing mode on the base, press a button on each sensor, and assign it a name like front door, or bedroom window. SimpliSafe's user-friendly web portal works well, though most will prefer the ease-of-use of the dedicated SimpliSafe smartphone app. Because you have the choice of self-monitoring, the total cost of securing your property with SimpliSafe is quite competitive. Even better, should you opt for one of the professional monitoring plans, you'll be pleased to see the lineup of monthly plans that don't require you to sign up for a 1-year contract.

Choosing the Best Home Security System on a Budget

There are a few basic considerations you should keep in mind when shopping for a new home security system. The first is deciding what level of security you need. Many cities provide online crime stats, and those in higher theft areas, are well advised to investing in an excellent home security system. Deciding how much you are willing to spend is next, though these low-cost systems are all very competitively priced. Finally, you'll need to decide if you want to handle the installation yourself, or if you'd rather let a team of professionals mount and connect the pieces together for you.

Even professional installation is quite reasonably priced on these budget-friendly systems. These excellent and low-cost home security systems can even snag you a reduction on your home owner's or apartment renter's insurance annual premium. Many of these home security systems are designed to be fully functional with little or no technical knowledge. There are a number of wireless security devices here including cameras, environmental sensors, doorbell cams and more that are essentially plug and play, making it easier then ever to cheaply secure your home sweet home.
