While many entrepreneurs get stuck on cybersecurity — as they should be — don’t let your concern for your digital security overshadow the need for physical, real-life security, either. If you work from home or keep important, secret information in the office, you want to protect it. With a Smart Home DIY Wireless Alarm Security System 4 Piece Kit, you can do that on a budget without sacrificing quality.

While many security systems come with comprehensive plans that will leave you paying a lot more than you should over time, this simple four-piece set lets you set up a smart security system to monitor your home or office from anywhere. The kit includes a Siren Hub gateway, two pairs of window/door sensors, and a motion detector that you can place anywhere you want to monitor when you’re not there. The app allows you to perform 24/7 monitoring and receive alert notifications of any activity via smartphones, smart devices and home automation systems.

The system is easy to set up with Wi-Fi connectivity that supports a wide range of smart devices. You don’t need professional installation or tools to get everything in place and working right away. Once they’re up and running, you’ll know when something happens at your home or office while you’re away and can quickly alert the authorities. Plus, the noisy siren can go off, scaring off would-be thieves or intruders before they’ve even accomplished their nefarious goals. There is no substitute for that kind of peace of mind.

Protect the things you care about most. At the moment, a Smart Home DIY Wireless Alarm Security System 4 Piece Set is on sale for 22 percent off $89 for just $69.99.
