What should you be aware of when using DIY security products?

*Although DIY products are inexpensive, problems can arise when it comes to maintaining the equipment and receiving the expected level of service.

Some people purchase security products at home improvement retailers and install them as a DIY project. However, if you are choosing, installing, and monitoring your own security equipment rather than relying on a private security or construction company, there are a few things you need to keep in mind. The difference between professional and amateur security system implementation is whether or not they emphasize the concept of “fail-safe.” “Fail-safe” refers to designing or installing a system so that it always operates safely (or immediately detects failures) in the event of a malfunction due to component damage or misoperation. For example, wireless sensors stop functioning when their batteries run out, so unless the system notifies you of a battery replacement, an alarm may not be activated in the event of an intrusion. It is also a big problem that the security system will be activated by mistake even if the door is not closed. Furthermore, if you build a security system by yourself, it may be difficult to respond if an alarm is activated when you are not home. The true value of a security system is revealed when an abnormal situation occurs. If you cannot ensure a “fail-safe,” you may need to ask for a professional.
