Best Home Security Systems in 2026

Home security systems work by allowing you to monitor your home with equipment such as cameras, window and door sensors, smart locks and motion detectors. If you buy all of your equipment from one company, it’ll typically be connected to a base station and controllable via a wall-mounted control panel and a mobile app.

Monitoring through a mobile app

Many security 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.

Types of home security systems

Some of the types of home security systems available include wired and wireless systems, professional and DIY systems, and monitored and unmonitored systems.

• Wired and wireless systems: Wired systems are connected through physical wiring, which makes them more reliable than wireless systems, but they require professional installation. Wireless systems are easier to install and move, making them ideal for renters or those who prefer a do-it-yourself approach.
• DIY and professionally installed systems: DIY systems are portable and usually less expensive, and they typically come with short-term contracts or no contracts. Professionally installed systems are typically more secure and reliable, but they come with higher costs and less flexibility.
• Monitored and unmonitored systems: Monitored systems connect to a response center that can contact emergency services when an alarm is triggered. Unmonitored systems sound a local siren, relying on homeowners or neighbors to take action.

DIY vs. professionally installed security systems

You can generally choose from DIY or professionally installed home security systems, though not every company may offer both. The best choice for you depends on your budget, home size and how much setup you're comfortable with.

Home security system costs can include upfront equipment and setup charges plus monthly fees if you want monitoring services. A basic security system usually costs between $300 and $600 to set up, though costs may exceed $1,000 for a top-of-the-line system with many devices. Some of the cheapest home security systems start at under $100 ($0 if you finance your equipment costs), with monthly fees of around $10. Monitoring costs typically range between $10 and $65 per month.

Note that monthly fees can 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

Some additional cost factors to consider include installation, activation, local alarm permit and termination fees.

• Installation costs: Professional installation costs start at around $100, and installation costs for extensive residential camera systems are generally higher, usually 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 installation price.
• 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 may need to pay the balance of your equipment costs, even if the equipment was advertised as free.

To choose a home security system, think about your home and what it will take to protect it from intruders. For example, someone who lives in an apartment building will have different equipment needs than someone who lives in a large house.

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 Wi-Fi boosters to strengthen your signal.

Choosing a system

To help you choose a system, consider:

1. If you want a professionally monitored system or an unmonitored system
2. What current customers say about a company online
3. If you want professional or DIY installation
4. If you want a wired or wireless connection
5. If you’re willing to sign a long-term contract

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 or a self-monitored system, there’s no monitoring center watching for an alert from your security system. Your alarm will still make a noise when triggered, but it’ll be up to you to contact first responders.

• Unmonitored alarm systems are best if you’re on a budget. These systems might work well if someone in your household can consistently monitor the system and respond to alerts in an emergency.
• 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. Read customer reviews

Reading customer reviews is the best way to find out what to expect from a company before you sign up for service. By reading home security service reviews, you can learn more about a company’s monitoring operators, installation technicians and customer service representatives.

While occasional issues with equipment or connectivity are normal, look out for patterns of complaints about unexpected charges, hard-to-cancel contracts, equipment issues and poor customer support.

3. Consider your installation options

Home security systems generally come with professional or DIY installation, though not every company offers both. 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.

Key features to look for

Some key features to look for in a home security system include 24/7 professional monitoring, mobile app access, two-way communication, automatic emergency dispatch, smart home integration and contract flexibility.

4. Compare your connection options

Some security cameras run on a cellular network connection, making them useful for remote locations without Wi-Fi access. Hard-wired cameras require cables for power and video transmission, but 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 might not cover all rooms.

5. Review your contract options

Choosing between a contract and a no-contract home security system is an important step because contracts often outline the length of service, costs and included services. A typical home security contract may run for one to three years and specify monthly monitoring fees, early termination penalties and any equipment discounts provided.

• Contract systems: These systems usually require a multiyear commitment and may include free or discounted equipment as part of the agreement. They often come with professional monitoring services and can be ideal for homeowners who plan to stay in one place for a while.
• No-contract systems: These systems provide flexibility and are typically month-to-month contracts. They are popular with renters or people who don’t want a long-term financial obligation. Equipment is often paid for upfront, but users have the freedom to switch providers or cancel at any time.

Match your security system to your home

Renters typically need wireless and no-drill equipment, while larger homes and vacation properties typically need more sensors, more cameras and professional monitoring services.
