The Ultimate Home Security Guide: Systems, Cameras & Smart Devices

One of the biggest issues is relying on just one camera and assuming it’s enough. A single front door view leaves blind spots around garages, side entrances, or back patios. Criminals typically look for exactly those gaps. Proper coverage means placing cameras strategically, not just “somewhere near the door.”

Another subtle but common mistake is poor placement. A camera mounted too high loses facial detail, and one pointed toward a bright window will wash everything out. A simple adjustment to eye level height and a downward angle can instantly improve clarity.

Many people also forget the basics: door and window sensors. Cameras are important, but sensors are the first to detect a break in. Without them, you’re reacting to trouble instead of preventing it.

Connectivity plays a role too. Weak WiFi is responsible for a lot of “camera offline” or “delayed alert” frustrations. If you have a larger home or thicker walls, a mesh WiFi system often makes the entire setup feel more reliable.

One mistake that surprises people is simply not arming the system. When it’s inconvenient, most folks skip it. Automations like schedules or geofencing solve this effortlessly: when you leave, the system arms itself.

Security also depends on digital habits. Leaving default passwords on a smart lock, hub, or camera is a risk that’s easy to avoid. A strong password and two-factor authentication go a long way.
