Best Home Security Systems of 2025

What is a home security system?

Basic home security equipment generally includes window and door sensors, door locks, and a central panel and base station that arms and disarms the alarm system. Optional devices frequently include video doorbells, indoor and outdoor cameras, glass-break sensors and home automation features, which are available at an additional cost. Home alarm companies typically include a set of yard signs and window stickers for free — research shows these are effective in deterring potential intruders.

Many burglar alarm companies’ monitoring packages also come with a mobile app that integrates smart-home automation features. You can use the app to self-monitor for emergencies and control household items like smart lights and smart locks.

Benefits of a home security system

Investing in a home security system offers many advantages, enhancing both safety and convenience for homeowners. Here's a look at the key benefits:

• Deterrence of crime
• Protection against burglary
• Increased sense of security
• Remote monitoring
• Home automation integration
• Emergency alerts
• Potential insurance discounts  

Home security system costs

Home security costs often include upfront equipment and setup charges plus monthly fees if you want monitoring services. A basic security system usually costs $300 to $600 to set up. Some of the cheapest home security systems can get you started for under $100 (or $0 if you finance your equipment costs), with monthly fees of around $10. Expect to pay a few hundred dollars for a basic system and $1,000 or more for top-of-the-line systems with a multitude of devices.

Financing or rental options can help make home security systems affordable.

Monitoring rates range between $10 and $65 per month. Monthly fees can also vary based on the type of system you have — for example, monitoring for a system with smart video capabilities costs more than monitoring for one without a camera. Some companies offer free or discounted equipment as long as you commit to paying monitoring fees for the long term.

Additional cost factors

• Installation costs: A wireless system should be simple to install — you can often do it yourself for free. Professional installation costs start at around $100, and installation costs for extensive residential camera systems are generally higher — up to around $500.
• Activation fees: Some companies charge a one-time activation fee of up to around $100 to get the system working. Others include the activation fee in the price of installation.
• Local alarm permit fees: Some cities or municipalities charge a yearly permit fee, usually $30 to $100, for local police to respond to emergency calls triggered by monitored home security systems.
• Termination fees: If you break your home security contract, you might be on the hook for the balance of your equipment costs, even if the equipment was advertised as free.

How to choose a home security system

Think about your home and what it will take to protect it from intruders as you shop. Someone in a 12th-floor studio apartment will likely have very different equipment needs than someone in a large home out in the country. If you have a large house, make sure your Wi-Fi is strong enough to reach devices in every room. If it’s not, consider getting a wired system (or installing some boosters to strengthen your Wi-Fi signal).

1. Decide if you want professional monitoring

Professionally monitored home security systems connect to response centers that dispatch emergency responders when an alarm is triggered. With an unmonitored system (sometimes called a “self-monitored” system), there's no monitoring center watching for an alert from your security system. Your alarm still makes a noise when triggered, but it’s up to you to contact first responders.

• Unmonitored alarm systems are best if you’re on a budget: These might work well if someone in your household can consistently monitor the system and respond to alerts in an emergency. However, they’re not as useful if you panic in high-stress situations or don’t consistently check your phone.
• Monitored alarm systems are best for 24/7 peace of mind: Depending on your subscription terms, operators can contact the police, fire department or medical services to ensure the appropriate response. You’ll likely need to pay a monthly fee for this service, though, and your contract may require a multiyear commitment.

2. Consider your connection options

Many top home security cameras are wireless and run on a cellular network connection, making them ideal for remote locations without Wi-Fi access. Hard-wired cameras are another option — though they require cables for power and video transmission, they provide reliable high-definition video that’s less susceptible to interference.

• Nationwide cellular networks: Cellular security systems may require professional installation, but they need little upkeep. With a battery backup, the system can even work during power outages. However, the cellular signal might not be strong enough to be effective, depending on where you live.
• Home Wi-Fi networks: These systems are easier to install and easier to take with you if you move. However, they might not work during power failures. In larger homes, the signal also might not cover all rooms.

3. Consider your installation options

Home security systems have two common installation options: professional or do-it-yourself (DIY). If you purchase a wireless home security system, you usually have the option to set it up yourself. Most hard-wired systems require professional installation.

• DIY installation: A DIY home security system is a great choice for renters because it’s portable. Plus, you can often get one with a short-term contract or no obligation. The best DIY home alarms are also generally less expensive than those that require a professional technician to install, but many homeowners feel safer with a wired system.
• Professional installation: Some consider hard-wired security systems more reliable since their peripheral devices don’t require batteries to operate. However, they can still be disabled during a power outage or by a thief with scissors.

4. Read reviews

Reading alarm system reviews is the best way to find out what to expect from a company before you sign up for service. Home security customers are usually vocal about unfair fees and durability issues in reviews.

Occasional issues with equipment or connectivity are normal, but look out for patterns of complaints about broken cameras, bad customer service and billing issues. By reading home security service reviews, you can also learn more about a company’s monitoring operators, installation technicians and customer service representatives.

5. Ask questions

It’s important to understand all the terms before signing anything. Even some of the top-rated home security companies get negative customer feedback regarding their cancellation policies, so look for companies that offer a free trial period or money-back guarantee.

Are home security systems worth it?

Home security systems can get expensive, but our research has found that they're often great additions to a home for multiple reasons — and experts agree.

"I think security systems are worth it, but the sad truth is most people don't realize that until after something bad has happened," Rebecca Edwards, lead safety expert of SafeWise.com, said. "It's a little bit like preventive health care — we all know we should do it, but if we feel fine it can be easy to put off."

The average loss per burglary is $2,661, according to the FBI.

First, and maybe most obvious, security systems are a great way to deter potential burglars. "When you look at the cost of not having a home security system, it's definitely worth it," said Edwards. "The average loss from a burglary in the US is around $2,600, and that's just the monetary cost. That doesn't even touch the emotional cost and losing your sense of safety in your home, which should be your sanctuary."

Even if a security system doesn't deter a burglar, the alarm can alert neighbors to trouble, and the monitoring center can call for the authorities. This is particularly useful if you're not at home or you can't get to your phone to call for help. Plus, security systems can provide more than burglar detection. The constant smart camera monitoring and home automation services can offer comfort and a little peace of mind.
