Home Security Guide: Systems, Cameras and Scam Checks

Maybe it started with a noise outside at night, a break-in down the street, or a salesperson at your door who said your neighborhood was getting hit. Maybe you just want to know what to buy before you spend money or sign anything.

This guide follows that decision in order: what you need to protect, how to set up a camera safely, how to check a company and its contract, how to handle a pressure sale, and how to keep things working when the power fails.

No single security system is the best for every house, and this guide does not rank brands. Start with what you need protected, check the company and the contract, then secure whatever you install.

Best system for your house No single answer. Choose by what you need watched, alarmed or monitored.
Camera setup Encryption, a unique strong password, two-factor login for cloud accounts, and automatic updates.
Contract terms to read Monitoring cost, contract length, early termination penalties, cancellation steps and refunds.
Pressure sale red flags “Act now” deadlines, “free” equipment tied to a long contract, and claims your current company went out of business.
Who to call before installing Your local police and fire departments, about registration, fees and false-alarm fines.
Official guidance used here FTC guides on securing home cameras (February 2023) and avoiding home security scams; Ready.gov home safety page (last updated 02/26/2026).

Step 1: Decide what you need protected

You know you want more security, but not yet what that means for your home.

A system can do more than sound an alarm. The FTC says systems can notify authorities about a medical emergency, offer video surveillance, and monitor smoke, carbon monoxide, and water levels or pressures. Some link into heating, lighting or wiring, and you can control them from a phone or computer.

Write down the parts you want: an entry alarm, video, a medical alert, smoke or water monitoring, or lights you can control. Each part changes the price and the contract. For physical basics like doors, windows and entry points, start with the break-in guide.

This guide does not rank security measures or list them by effect. If your property has no grid power, the low-tech perimeter guide covers detection and lighting that work without electricity.

What this means for you: Make a list of the spots you most need covered first. That list is what you take to every company you consider.

Once you know what you want watched, the next question is whether the cameras can be trusted.

Step 2: Lock down a camera before you rely on it

You are thinking about a doorbell camera, a baby monitor or a security camera, and you want to know whether someone else could watch it.

The FTC says these cameras can be hacked, and it gives a clear setup order. Work through it before the camera goes live.

  1. Before you buy, look for built-in security features. The FTC says to look for a camera that encrypts account information, livestreams and archived videos.
  2. Secure your router. Use a strong password, confirm the firewall is on, install updates, and check that wireless is encrypted with WPA3 or WPA2.
  3. Consider a separate network for cameras, so a hacked computer does not give easy access to them.
  4. Replace the default username and password. Use a strong one you have never used anywhere else.
  5. Turn on two-factor login for any cloud account if it is offered.
  6. If you log in through a browser, the address must begin with https, and it should still show https after you log in.
  7. Limit remote viewing to devices and accounts you have locked down. If the camera lets you disable remote viewing, the FTC suggests considering that option.

If you plan to share your feed, look for a camera with permission levels. The FTC notes some cameras let you name an administrator, and others control who can watch and when.

What this means for you: If a camera cannot do encryption or two-factor login, that is a real gap to weigh before you pay.

A camera is only as safe as the account behind it. The next step is the company that monitors the system.

Step 3: Check the company and the contract before you sign

You are comparing companies, and you may be a first-time buyer wondering which name to trust. The FTC checklist applies to any company you look at, whatever its name, including ADT.

Get these answers in writing before you sign.

Question to ask Why it matters
What happens if the power goes out? Ask whether there is a back-up battery system.
Who installs and monitors it? Some companies subcontract this work to third parties.
How long is the contract? Check for penalties for early termination, and what happens if you move.
What does monitoring cost, and how often are you billed? Find out whether the company or the authorities are called first when an alarm goes off.
What does the warranty cover? Ask whether it comes from the manufacturer or the installer, and who pays for repairs.
What happens if you cancel? Ask how refunds are handled before you sign anything.

Ask friends, family and neighbors for references, and search the company name with words like “complaint” or “scam”. Check that contractor licenses are current; the FTC points to the National Association of State Contractors Licensing Agencies to find your state’s agency. Get written estimates, since reputable companies learn about your home’s layout before they sell.

The written contract should include every promise the salesperson made, be dated, and show the seller’s name and address. Confirm it also lists the installation price, the monitoring fee, the contract period, any discounts, a written warranty, the owner’s manual, and your cancellation forms. Then contact your police and fire departments about registration, any fee, and fines for false alarms.

What this means for you: If someone says you must act now, slow down. A good deal will still be there after you read the cancellation terms.

If someone is at your door right now, the next step is simpler than the contract.

Step 4: Deal with a salesperson at your door

A stranger is at your door with a deal that has to be signed today.

The FTC says door-to-door sales are legal, and many honest companies use them. Scammers and dishonest businesses use the same approach, so watch for these signs:

  • Pressure to act now, or “free” equipment that comes with a long, expensive monitoring contract.
  • Scare talk about a rash of burglaries nearby. Check with your local police before you believe it.
  • Claims that they are from your current security company, that they are there to “upgrade” your system, or that your company has gone out of business.
  • Refusal to leave. The FTC says it is easier to say no on the doorstep, and to call the police if a salesperson will not go.

Some states require salespeople to give their name, the business they represent and what they are selling before they ask questions. Other states require a “pocket card” license and a photo ID, so ask to see both. If anyone claims your company has changed hands, call your current monitoring company directly.

What this means for you: If the visit does not fit the FTC signs above, you do not owe anyone an answer at the door.

Once the door is closed, look at exactly what you would be buying.

Step 5: Look at a specific product with the same checks

You have seen an ad or sales video for a security product, and you want to know whether it is worth buying.

Product pages show what the seller says. Treat each feature and claim as the seller’s statement, and run it through the camera and contract checks above. Ask for the trial terms, the date of the first charge and the cancellation steps before you enter payment details.

The site has product guides for offers you may see. The Tactical USA home security offer guide covers features, trial terms and buyer checks. For a doorbell system, the Vital Smart Door Home label, price and buyer checks guide covers the label details to confirm, and the Vital Smart Door Home alternatives guide compares it with other options.

What this means for you: Compare the total cost over the full contract, not the first price on the page.

Next, make sure your protection still works when the grid goes down.

Step 6: Keep protection and records working when things go wrong

The power goes out, and suddenly the alarm and the cameras are a question mark.

Plan for it before it happens. The Ready.gov home safety page says millions of people seek medical care each year after injuries at home, and it lists falls, poisoning and burns as common causes. It also recommends a well-stocked first aid kit and first aid training.

For electronic locks, alarms, cameras and outdoor lights, find out how long the battery backup lasts and whether alerts still go out. Test that plan with the lights off, not in a storm.

When something is lost or damaged, insurers and agencies ask for proof. A written and photographed home inventory with serial numbers is the starting point, and it should be stored somewhere that would survive the same fire or flood. Keep your emergency kit documents current, since insurance, account and contact records change often.

What this means for you: Your alarm is only one part of your plan. Write down how you will stay in touch, and where your paper copies are.
