Highly praised, the Fortress Security Store SO2-A security kit is an excellent option for DIY alarm fans looking for versatile solutions. The 110dB alarm offers more than enough volume to wake the neighbors and make potential intruders think twice. The alarm noise is complemented by the main control panel with auto-dialer (calls up to six numbers in a security breach) that supports five door/window contacts, two passive motion detectors, two key fobs for activating and deactivating the alarm, a panic alarm and four alarm stickers for placement around the house. Upon activation, the SO2-A can call any designated number in the event of a breach and play both a recorded message or custom sound. Homeowners can also call the system from their mobile phone and listen in around the house. Additional sensors for doors and windows, plus motion detectors, are all available for purchase to add extra protection throughout a home.

Supporting up to 99 sensors in total, the Digoo wireless home and business security alarm is a budget system that offers effective security for its inexpensive price tag. Compatible with Wi-Fi, GSM, GPRS, 2G, 3G and 4G networks, the Digoo offers a 2.4-inch digital display alongside its touchpanel design. The wireless remote easily allows for alarm activation/deactivation for all sensors, as well as offers real-time push notifications to your smartphone. The system adds one touchpanel, two remotes, two door/window sensors and one motion sensor (additional accessories can be purchased separately). The automatic timer allows homeowners to activate the alarm whether they’re home or not. With support for gas, carbon monoxide, and smoke detection, the Digoo is truly a well-rounded alarm solution.

Bibene’s Wi-Fi-ready home DIY home security system is a superb value for the budget-friendly alarm shopper. Equipped with a 120dB alarm, SOS emergency and pet immunity, the Bibene is ready out of the box. The DIY kit includes the main control panel, one motion sensor, five door and window sensors, plus two remote controls. The sensors and remotes are already connected to the control panel, which eliminates extra steps during setup.

The main panel is designed specifically for one-handed operation, so arming, disarming, adjusting alarm volume and changing ringtones can all be done easily and quickly. Without installation fees, monthly contracts or monthly monitoring fees, the Bibene offers more sensors upon purchase than other budget-friendly competition. The available Android and iOS apps easily support the addition of new sensors or monitoring equipment for added protection.

One of the most inexpensive options available, the Sabre wireless home security system offers bare-bones packaging without sacrificing protection. The 120dB alarm is loud enough to be heard up to 750 feet away to help deter intruders and alert homeowners there’s trouble. There are three adjustable settings (off/alarm/chime); the chime is an easy solution for alerting you to doors opening and closing, a good solution for parents.

Each Sabre package comes with detailed instructions and images to help with the DIY process, including suggestions for proper placement for the best protection and how to set up your four-digit pin. There’s no wiring necessary as the keypad, door and window alarms are all powered by AAA or LR44 batteries that can easily be swapped after notification of low battery life.

For smaller homes, apartments or offices, call upon the Doberman 8 alarm security system for peace of mind and added security. The simple peel and stick installation is ideal for novice DIY types. The equipment includes the four window alarms, two entryway defenders ideal for doorways and two ultra-thin window protectors perfect for sliding glass doors. The peel installation option is a standout solution for shoppers who want to adjust positioning frequently or take their alarm system with them if they ever move.

With no main control panel to utilize, these alarms are best left in the always-on position, so the 100dB alarm can activate in the event of an intrusion. Once an intrusion is detected, one of two alarm chimes will activate.

With a setup time that’s under 15 minutes, the Oxa Smart Wi-Fi alarm is an outstanding DIY option. Compatible with both Android and iOS, the Oxa even works with Amazon’s Alexa Skills for increased functionality. The included door and window contact sensor, motion sensor, remote controller and waterproof doorbell button can be complemented by separately purchased items that can be quickly added to the existing system through the smartphone application.

The 80dB alarm isn’t the loudest available, but your neighbors will hear it in the unfortunate event of a home or office intrusion. Without any complicated wiring to confuse the initial install process, novice DIYers will find the Oxa to be a fast and precise alarm system that offers omnidirectional security with the Smart Hub recording audio for later playback. If the alarm is sounded, the Wi-Fi-based system will notify homeowners with smartphone notifications that can also be sent to neighbors or family for extra awareness.

Don’t let the budget price fool you, the Coowoo smart home security system offers all the protection of more expensive options without monthly monitoring fees. Compatible with Amazon’s Alexa Skills, the Coowoo can be voice-activated and deactivated through an Echo device or through the Alexa app on both Android and iOS. The installation process is quick and easy right out of the box; it's a tool-free setup that’s plug-and-play relying on the smartphone to connect all the included pieces together for one cohesive alarm system.

All totaled, the Coowoo supports more than 50 separate sensors with one smart Wi-Fi hub, which includes the motion sensor, two-door/window contact sensors, remote control and a waterproof doorbell button. The 80dB alarm won't rupture your eardrums, but it will ward off any potential threats. The system also comes with a remote control that can activate and deactivate the alarm from anywhere in the world.

Featuring a 120dB alarm that’s detectable from up to 750 feet away, Sabre’s expandable alarm security system is a great choice for larger homes. Notably, the Sabre’s biggest selling point is the ability to add an unlimited number of sensors to its main panel, which allows for larger spaces to be properly detected at a fraction of the cost of a professional alarm system. With four operation modes (alarm, alert, home and standby), sensors can be placed up to 500 feet from the main control panel on either side without any interference.

The LCD smart panel is complemented by two door and window sensors, one remote control and a motion sensor. Adding extras is inexpensive, so buyers can add protection all over their property and still keep costs low. Other pluses: There are no monthly monitoring costs and a backup battery means you can stay protected in the event of a power outage.
