We explain how below, along with listing the most affordable home security systems in our ratings so you can decide which one best suits your needs.

Ring Alarm: Ring's $199 base system, called the Ring Alarm Security Kit, includes a base station, a keypad, a motion detector, a contact sensor for doors or windows, and a device that extends the range of the communications between the devices. The company's $10 per month Protect Plus plan for professional monitoring is a bargain. However, a Ring security system is relatively basic and doesn't currently integrate with many third-party home automation devices that work with competing systems. Read More»

This approach may appeal to those who want a simple, no-frills system that's easy to set up and use. Cove's equipment prices are about average among our rated home security systems. Read More»

The cost of a home security system can be steep, with hundreds or thousands of dollars invested in equipment and even more in long-term monthly monitoring fees. As a result, there's a temptation to buy as inexpensive a system as possible upfront. But while there are relatively affordable home security systems on the market, it's a mistake to focus solely on price. For several reasons, a cheap home alarm system might not meet your needs.
One way to save money is to avoid installation fees by purchasing one of the DIY home security systems in our ratings. But some of these systems include rather basic equipment that doesn't integrate with smart home devices, which you might consider a priority. Plus, you won't get the benefit of an in-home security consultation, and no one will come to troubleshoot if there's a problem. Thus, while DIY systems are fine for many people, if you want the best available equipment and the highest level of customer service and support, a professionally installed system is the way to go.
Before buying a low-priced home security system, ask yourself these questions:
- What level of service do you want? Make sure the company you're considering provides the customer service experience you're looking for. Are knowledgeable technicians readily available to answer your questions? Do they provide sound advice, or try to sell you equipment you don't need? How easy is it to repair or replace equipment if it fails? If the company saves money by skimping on customer service, that could present problems both now and down the road.
- Are you trying to save money by purchasing a base package with only a few sensors? Don't leave vulnerable areas in your home unmonitored, as that could create an easy target for burglary.
- Is the system you're thinking about easily expandable? You might want more security equipment later on, so make sure it's available and your system can accommodate it.
- Do you want just home security devices, or smart home devices as well? Some lower priced home security systems don't integrate with smart door locks, smart thermostats, personal assistants like Amazon Alexa, and other internet-connected equipment you might decide to add later.
Pros and Cons of Cheap Home Security Systems
Pros
Can provide all the security you need, especially if you have a smaller home.
Can provide as much peace of mind as a more expensive system.
Can keep you from wasting money on equipment you don't need.
Cons
Might not offer enough protection for all entry points and other security vulnerabilities.
Might not offer the expansion options you need or want later.
Might come with poor-quality equipment that will malfunction, causing a security risk.
To choose a home security system, take the following steps:
- Decide how much protection you need. This depends largely on the crime rate in your area and the parts of your home you want to monitor or protect. Decide if you want protection just while you're away or also while you're home, particularly at night. To protect your home just while you're away, you probably only need a couple of door sensors and motion detectors, along with fire alarms. But if you're concerned about someone breaking in while you're home, you'll want a more comprehensive system that covers all likely entry points. Equipment may include a full suite of door sensors, glass-break sensors, and motion detectors. For an extra layer of protection, also consider adding outdoor cameras.
- Determine your budget. Adding more sensors and cameras to a basic home security package can quickly increase your final bill.
- Choose DIY or professional installation. This decision comes down to your time available, level of comfort with electronic equipment, and budget, as you can avoid installation costs with a DIY system.
- Schedule an in-home consultation. If you want to have your system professionally installed, set up a meeting with a representative from the security company so they can visit your home, consult with you face-to-face, and prepare a proposal.

For the cheap home security systems in our ratings, the 12-month total cost of ownership ranges from $235 for Ring to $493 for Cove. Monthly monitoring prices range from $3 for Ring to $15 and up for Blue By ADT. Equipment levels and monitoring features vary, so be sure to read the fine print.
Affordable home security is an achievable goal, but it requires research and priority-setting. Do you really need a sensor on every window, video cameras indoors and out, and the latest in home automation technology? Do you want professional monitoring, or are you willing to self-monitor your system? Can you install the system yourself? Answering these and other questions will help you identify areas where you can save money.

One way to get more affordable home security is to be sensible when selecting what equipment you purchase. Most home security companies offer a wide array of equipment with different features and price points, including several types of cameras and sensors, home automation equipment, etc. Just because you can add something to your system doesn't mean you have to. For example, you might be able to forgo niceties like large hard drives for video storage, cameras with two-way audio, internet-enabled door locks and other gadgets, and sensors on upper-floor windows unless they are somehow easily accessible. A professional security assessment can help to determine what's truly essential. You can also design a good system yourself after first doing some research and then carefully evaluating your security issues.
Certain pieces of equipment are essential or highly recommended for any security system, starting with a central hub to which all the sensors and cameras are connected. At a minimum, security experts also recommend sensors on every entry door and first-floor window, interior motion detectors for when you're away from home, and smoke and carbon monoxide detectors connected to the security system so that you and/or a professional monitoring center will be notified in an emergency. Some experts say outdoor security cameras aren't essential, though they are useful for monitoring entry points and places hidden from neighbors. Beyond these basic items, feel free to limit your purchases for a more affordable home security system. Most systems are expandable, so you can always add equipment later if you wish.
For more information, see How does a Home Security System Work?
Equipment You Should Have:
- Central hub
- Sensors for first-floor doors and windows
- Motion detectors
- Smoke/carbon monoxide detectors
Equipment That's Nice to Have
- A keypad (to control the system other than on your smartphone)
- Sensors for upper-floor windows
- Security cameras
- Home automation devices
- Flood and freeze sensors
Most home security systems come with the option of professional monitoring. For an extra fee of about $10 to $40 a month, the security company's trained staff will monitor your system around-the-clock and notify the authorities if there's a fire, burglary, or some other emergency.
Some more affordable home security systems allow for free self-monitoring on your smartphone. While self-monitoring lowers the cost of home security, it has significant drawbacks and is discouraged by most home security experts. The primary issue with self-monitoring is that it's impossible to continuously monitor your own security system (while you're sleeping, for example). Moreover, even if you check your security system on your smartphone occasionally when you're away from home, you might not notice there's a problem until it's too late. If there's a fire, the difference between saving and losing your home could be a matter of minutes. Moreover, because burglars usually grab whatever they can in a short time and flee, they might be long gone before you see the video footage of the break-in. With professional monitoring, you can rest assured that as soon as something happens, security company staff will receive an alert and notify the proper authorities. As a result, self-monitoring probably isn't the smartest choice in your quest to save money on a security system.

Pros and Cons of Professional Monitoring
Pros
Security assessment included.
Installer can provide advice and usage instructions on-site.
Can be better for more complex installations.
Cons
Requires installation fee.
Requires scheduling time with a technician.
Leased equipment often requires a contract.
A better way to lower the cost of home security is to buy a system that you can install yourself. With a professionally installed system, a technician visits your house and performs a security assessment to determine what equipment you need and where it should be placed. He or she then installs it for you for a fee of $100 or more, depending on the company and the size of the system.
This approach has significant advantages. Most importantly, you get a security system that's tailored to your home. You also will have someone to call if there's a problem with the equipment later. However, be aware that the technician might encourage you to purchase more equipment than you need. To help avoid this, ask whether a company's technicians are paid a flat rate or a commission based on the size of your system.
If you're looking for a lower-priced security system, consider one that you self-install. These systems use your home's Wi-Fi network to communicate with the central hub. This means the equipment doesn't need hard wiring and is relatively easy to set up without tools or damage to your walls. Easy-to-follow setup instructions are provided, often on a smartphone app. Depending on how much equipment you purchase and how familiar you are with Wi-Fi-enabled electronic devices, installation could take anywhere from half an hour to a couple of hours. Remember that although most DIY home security companies provide phone support, you will have to fix any technical issues that arise or send the equipment back if it's defective.
