Features of Affordable Home Security Systems

  • DIY Installation

    One of the most common features you’ll find among affordable home security systems is DIY installation. Being able to install your system yourself allows you to avoid an installation fee, which could range anywhere between $70 to upwards of $300 depending on the provider and equipment. You also won’t have to be concerned with setting aside time for a technician to install your system for you when you can do it yourself.

  • No Contract

    Another feature that can lower your security system cost is the ability to avoid any contracts. Traditionally, home security providers have required a contract for their service, but a lot of providers today are either transitioning away from this or adding DIY systems to their lineup. With some affordable home security systems, you’ll only be responsible for your monthly monitoring fee.

  • Inexpensive Monitoring

    One last feature you’ll find is inexpensive professional monitoring. This is more common with DIY providers, where the cost of monthly monitoring can start below $10/mo. You’ll want to be sure of the type of monitoring you’ll have before purchasing, whether that’s professional or self-monitoring. Self-monitoring is typically cheaper, as you’ll be responsible for getting activity notifications, but we’d recommend choosing professional monitoring whenever possible.


A cheap home security system can provide peace of mind just like some of the more expensive alarm systems on the market. You can always choose a basic starter kit and add additional equipment over time. If you decide you want more advanced technology, or a lifetime warranty, you may want to go with a pricier provider. But there are plenty of cheap home alarm systems that can protect your home with basic home security equipment.
