Home Security system types, plan terms and choosing a provider
DIY systems collapsed the price of the hardware. The comparison that still matters is the subscription behind it.
How a home security system works
A home security system is a set of door and window sensors, motion detectors and cameras reporting to a base station, plus a plan that decides who responds when the alarm goes off. Choose the response first; the hardware follows from it.
Self-monitored systems send the alarm to your phone and leave the next step to you. Professionally monitored systems send it to a staffed center that can call you and dispatch police. The plan is paid every month for as long as you keep it, which makes it the larger part of the decision over the years the hardware lasts.
The self-installed systems have also ended the era of the three-year contract. Both of the major ones sell month to month, which means the plan you pick is a decision you can revisit rather than one you sign away, and that changes how you should shop.
No form on this site asks for your name, phone number or address on behalf of a security company. Each link opens the provider’s own site, where the system is sold.
Six home security plan terms to read before you buy
Every system is advertised on its hardware and paid for through its plan. These are the clauses that set what you actually spend, in the order worth reading them.
| Term | What it is | What to check before signing |
|---|---|---|
| Monitoring tier | Whether a monitoring center watches the alarm, or the app just notifies you. | Self-monitoring is much cheaper and means you are the one who has to notice at four in the morning. Decide honestly which of those you are buying. |
| Professional dispatch | Whether the plan includes a human calling the police on your behalf. | It is not on every tier, and on some systems it is an add-on rather than an upgrade. Check the price of the tier that includes it, not the entry tier. |
| Video verification | Whether an agent can open the camera during an alarm and see what is happening before dispatching. | A growing number of police departments prioritise verified alarms. One provider builds this into a plan tier; another sells it as a separate premium service. |
| Video history | How long recorded events are kept, and whether continuous recording costs extra. | Retention runs from days to months across providers, and per-camera continuous recording is usually a separate line on the bill. |
| Contract and backup | Whether the plan requires a term, and whether the base station keeps reporting without power or broadband. | The DIY systems are month to month. Cellular and battery backup should be included rather than an upgrade; if they are not, the alarm stops at the first outage. |
| Permits and false alarms | What your municipality requires of a monitored alarm, and what it charges when one is false. | Most American cities require an alarm permit and fine repeat false alarms. Look up the ordinance before the system goes live, not after the first invoice. |
Plan prices and tier names change often on both major systems, and neither publishes a stable page a comparison can cite. Check the current price on the provider’s own site before buying, and compare what a tier does rather than what it is called.

Choosing a home security system: questions answered
What does a home security system include?
A base station or hub, contact sensors for doors and windows, at least one motion detector, a keypad or app to arm it, and a siren. Cameras, video doorbells, smoke and leak sensors and smart locks are added on top, and most systems let you start small and extend.
Should I choose a DIY or a professionally installed system?
Wireless DIY systems go up in an afternoon with adhesive strips and leave with you when you move. A professional install makes sense for a large house, hardwired sensors already in the walls, or when you want one company accountable for the whole setup.
Does a security system work during a power or internet outage?
Only if the base station has battery backup and a cellular connection. Without them the alarm goes quiet at the first outage, which is when it is most likely to be needed. Confirm both are included before choosing a plan.
Are cameras or sensors more useful?
Sensors stop an entry; cameras record one. A camera on every corner and no contact sensors is a documentary of your break-in. Put the sensors on the doors and the accessible windows first, then add cameras where they answer a question you actually have.
How do I choose a home security provider?
Compare what each plan does when the alarm trips: who is alerted, whether an agent can see video before dispatching, how long footage is kept, and whether the plan runs month to month. The brand name on the hardware matters less than those answers.
What should I secure before buying a system?
Lighting, sightlines and a solid deadbolt do more per dollar than anything with a subscription. A security system is worth buying once the cheap physical work is done, not instead of it.
