The strategic placement of these sensors is key. Cover all ground-level windows, entry doors, and any other vulnerable access points. Don’t overlook garage doors or basement windows, which are often targets for discreet entry.
Combining door and window sensors with smart cameras creates a layered defense. If a sensor is triggered, your cameras can automatically begin recording and send you a notification, providing visual verification of the event. This synergy enhances your home’s overall security posture significantly.
smart lighting and automation for added security
Smart lighting and home automation are often overlooked but incredibly effective components of a DIY smart home security system. Beyond convenience, these features can deter potential intruders by making your home appear occupied, even when it’s not.
The psychological impact of an active home can be a powerful deterrent.
Smart bulbs and plugs allow you to control lights and other appliances remotely or schedule them to turn on and off at specific times.
This functionality mimics human presence, making your home less appealing to those looking for an easy target. Moreover, motion-activated smart lighting around the exterior can startle and expose intruders.
creating a ‘lived-in’ look and deterring intruders
Implementing smart lighting doesn’t require a huge investment. A few smart bulbs or smart plugs strategically placed can make a significant difference. Look for Wi-Fi-enabled options that don’t require a separate hub, further saving costs.
