Choosing a Home Security System
Five decisions decide everything else, and they have a correct order. Taken in this sequence, most households reach an answer in ten minutes.

Decision one: monitored or not
This is the fork everything else hangs off. Monitored means an operator receives the alarm and dispatches police or fire whether you are reachable or not, and it means monitored smoke detection. Unmonitored means a siren and a notification to your phone. If the house is regularly empty overnight or you want life-safety coverage, monitored is the answer and the remaining decisions are about scale. If you mainly want a deterrent and a recording, unmonitored is a legitimate answer and not a lesser one.
Decision two: can you accept a 36-month term
Monitoring carries a 36-month term. Early exit is prorated and falls each month, but it exists. If you are renting, expecting to move within three years, or simply unwilling to commit, that fact alone should route you to an equipment-only package regardless of how the first decision went. Deciding this second, rather than discovering it at the end, saves everyone a conversation.
Decision three: professional or self install
Housing stock decides this more than preference does. Homes built before roughly 1970 have plaster-and-lath, thicker masonry and non-standard door frames — adhesive mounting fails and radio range shortens, in ways that are not obvious until the system will not arm. Newer drywall construction with standard frames is genuinely fine to self install. Outdoor cameras push the answer toward professional in either case, because aiming and weather sealing are annoying to redo on a ladder.
Decision four: how many sensors
Every exterior door, then ground-floor opening windows, then glass-break for large fixed panes, then one motion detector on the interior path connecting the entry points. Three to four devices for an apartment, four to six for a typical three-bedroom, eight to twelve for a four-bedroom with a patio slider and a side door. Add one monitored smoke detector if the system is monitored — it is the highest-value single device and the one most often omitted.
Decision five: cameras, and what you want them to do
Be specific about the job. Answering the door from anywhere is a doorbell camera. Seeing who is on the driveway at night is a 2K outdoor camera with a spotlight, because 1080p will not resolve a face at that distance. Producing evidence means 2K minimum and local storage so footage survives an outage. Video verification for faster police dispatch means cameras on a monitored panel specifically — the same camera on an unmonitored system does not do it.
The sequence in one line
Monitored or not, then can you accept the term, then who installs it, then how many openings, then what the cameras are for. Answering them out of order is what produces a system that is either over-specified for the household or missing the one device that mattered.
Where This Leads
The specification pages below carry the full figures behind everything above — speeds, upload, latency, device lists, sensor counts and contract mechanics.
Availability and terms depend on the address, so both are confirmed on the call. The arithmetic above gets you to the right tier or the right device count; the call confirms what actually provisions where you live.
Common Questions
Should I buy cameras or sensors first if I can only do one?
Sensors. A camera records an intrusion that already happened; a sensor detects it while it is happening and, on a monitored system, produces a response. Cameras are the higher-satisfaction purchase and the lower-value one in security terms.
Is a bigger package always better?
No. Sensors on openings nobody can reach add battery maintenance and false-alarm exposure without adding coverage. The right system covers every realistic entry path and stops there.
How long does the whole process take from first call?
Five to twelve business days to a professionally installed monitored system, most of which is the appointment lead time. Three to seven business days for an equipment-only package to ship. The sizing conversation itself is one call.
What is the single most common regret?
Leaving off monitored smoke detection to keep the device count down, and mounting motion detectors facing a window. The first is a coverage gap you find out about badly; the second is a nuisance you find out about within a week.
