Wireless home security systems work using iInternet or cellular signals to send alerts when sensors are triggered. Most DIY security equipment is purchased upfront instead of leasing. They’re ideal for renters because they typically don’t require professional wiring or drilling. DIY wireless equipment is easy to install using one screw, removable adhesive or plugging into a standard wall outlet to eliminate the cost of professional installation. When it’s time to move, you’ll be able to pack up the security equipment and reinstall at your new home. All of your wireless equipment connects to a control panel or hub and can easily be controlled using your smartphone or web portal. The best part is if there’s a power outage, most wireless equipment includes a backup battery to work. Monthly plans are often less expensive than wired home security systems, but there are drawbacks to consider. Choose a DIY home security system if you want to save a little more, have more freedom with equipment placement and easier transport when moving. With a DIY security system, you won’t have to pay an installation fee, which allows you to save a little more. These systems also don’t tend to cost as much as the professionally monitored systems.
