Home security setups fail most often not because the hardware is bad, but because it's the wrong hardware for the property. The right starting question isn't "which camera is best" — it's "what am I actually trying to see or stop".
For most homes, that means covering entry points first: the front door, back door, and any ground-floor windows that open onto a street or alley. A camera covering an empty side garden is far less useful than one covering your actual front gate.
Door and window sensors are the cheapest way to know something opened when it shouldn't have, and they work even during a power cut on plug points, since most run on their own battery.
A smart lock is a convenience feature more than a security one — its real value is knowing exactly who came and went and when, and being able to revoke a guest's access instantly instead of re-keying a physical lock.
Motion sensors tie the rest together: paired with an automation, they can turn on lights, trigger a camera to start recording, or send you an alert — turning separate devices into one coordinated system instead of a pile of gadgets.
