How much are home security systems?

The cost of home security systems depends on the equipment, plan, installation and more. Most of these costs include home security equipment such as security cameras, video doorbells and sensors. Your monthly home security cost can also include 24/7 professional monitoring services, security camera footage cloud storage and the ability to control your home security system using your security provider’s mobile app. You’ll be able to easily manage your smart lights, thermostat and other home security gadgets. Today, the best home security systems can range from $15.99/mo., or up to $54.99/mo. for a plan with additional features and equipment.

Adding up common home security costs

There are a few fees to expect when adding up your home security cost. You’ll want to factor in installation, activation, equipment and any added services such as professional monitoring. Each cost will vary based on your security provider.

Professional installation

Some home security systems require a technician to professionally install your home’s security equipment. After you schedule the installation appointment, you won’t have to worry about spending time wiring or drilling to install your home security system. However, professional installation can cost over $200 but may be discounted depending on the security provider or equipment purchased.

System activation

You’ll also want to factor in any activation fees to turn your equipment on. Activation fees are often included with installation and can range from a one-time fee up to $100. Before buying a home security system, ask about any activation fees, when it should be paid (on your next bill or before installation) and if the activation fee covers all equipment.

Security equipment

Add up the cost of all the security equipment you’ll need to help protect your home. This often includes any security cameras, sensors and control panels. Depending on your home security system choice, you’ll pay a monthly fee to rent the equipment for a time frame – at least a year. But with DIY home security systems, you’ll most likely purchase all equipment upfront. Most equipment for basic packages ranges from $15 to $30/mo.

Professional monitoring

If you’d like your security provider to watch over your home 24/7, there’s an additional monthly fee. If a sensor is triggered, the monitoring center will contact you to alert you of any suspicious activity. Professional monitoring can start at $14.99/mo. for DIY home security systems and $28.99/mo. for professionally installed systems. Keep in mind, professional monitoring often requires a contract, but some month-to-month plans are becoming more popular.

Monitored vs. unmonitored home security systems

Monitored home security systems come with professional monitoring services to watch over your home 24/7 to alert you and emergency responders if a sensor is triggered to help protect your valuables from burglaries, fire and smoke detection. The lowest basic ADT plan includes professional monitoring costs $28.99/mo. It all depends on your home’s security needs.

But bear in mind that if danger is detected, professional monitoring services will contact you first if a sensor is triggered. After the security provider has reached out to you and any emergency contacts they’ll contact the police on your behalf. So, the lag time between the triggered sensor and emergency responders getting to your home could be lengthy.

On the other hand, unmonitored home security systems will automatically notify you directly when a sensor is triggered. Once you’re notified, you’ll have to determine whether or not it’s a false alarm or if you should call emergency services. DIY home security systems are less expensive because most features and equipment are purchased upfront – such as SimpliSafe’s professional monitoring package is as low as $14.99/mo.

Wired vs. wireless home security systems

Wired Security

Wired home security systems tend to cost more due to installation and monitoring. They rely on radio frequency to receive signals of triggered sensors. Most wired home security systems include a control panel or hub and motion sensors to help protect your home. Some providers also offer security cameras and other security equipment. Wired home security systems often require professional installation to connect to your home’s electric and phone system making them more reliable in areas with low cellular signals. But there are a few factors to consider with wired home security systems.

Wireless Security

Wireless home security systems work using iInternet or cellular signals to send alerts when sensors are triggered. Most DIY security equipment is purchased upfront instead of leasing.  They’re ideal for renters because they typically don’t require professional wiring or drilling. DIY wireless equipment is easy to install using one screw, removable adhesive or plugging into a standard wall outlet to eliminate the cost of professional installation. When it’s time to move, you’ll be able to pack up the security equipment and reinstall at your new home. All of your wireless equipment connects to a control panel or hub and can easily be controlled using your smartphone or web portal. The best part is if there’s a power outage, most wireless equipment includes a backup battery to work. Monthly plans are often less expensive than wired home security systems, but there are drawbacks to consider.

Adding additional home security equipment

Once you’ve set up your home security system, you may need to add extra security cameras or sensors to monitor blind spots that may be out of range. Some home security companies sell additional equipment at a discounted rate if you’ve purchased their home security system. If not, adding additional equipment can be fairly inexpensive. Adding an extra indoor security camera can cost upwards of $100 or an extra door sensor can cost around $30. Before buying more equipment, make sure you know how many home security devices each control panel or hub can accommodate at once. Also, if you’re installing add-on equipment, ask about any additional fees such as extra cloud storage for security camera footage. If you’re not buying the security gadget upfront, ask about the leasing price and any additional terms.  

Extra home security system costs to consider

With so many new features, you’ll want to determine which features are ‘nice to have’ or a necessity for your home security system. Here are the top features to factor into your home security cost.

Smart home automation

Some home security companies offer plans to connect home automation equipment such as smart locks and smart lights. You’ll be able to create routines to automatically turn lights on or turn your home’s smart thermostat temperature down when you leave for work. Home security companies normally offer smart home automation capabilities at an additional cost.

24/7 live camera footage

Home security companies offer continuous video recording (CVR) to record and store all of your security camera’s footage so you never miss a moment. Normally, security cameras only record motion-triggered activity – which is only a few minutes. Most home security companies offer CVR plans in increments of 7, 10, 14 and 30 days.

Cloud video storage

If you’d like to keep your security camera video coverage stored safely away from hackers, you’ll want to consider cloud storage options available. Most security providers encrypt all data and footage using encryption. Some home security companies charge $5 to $30 a month depending on how much video storage space you’ll need.

Remote control

If you’d like to control your home security system using your smartphone, you’ll typically pay extra to disarm your security system on the go and receive motion-detected mobile notifications when sensors are triggered in your home. For remote control, you’ll most likely need an upgraded plan, but downloading the mobile app is free.

Understanding home security contracts

Hidden home security costs and fees are often found in the fine print of your contract. Read the contract and ask the security provider to explain anything you don’t understand. Think about early cancellation fees, reinstallation fees from moving or overlooked equipment leasing terms. Make sure you understand monthly fees included in the contract and any upfront home security costs to be paid upon activation. Here are a few quick tips to keep in mind when reviewing your home security system contract.

Factors to consider before buying a home security system


Overtime, your home security system may need repairing or replacing for a few reasons. It could be an installation issue, false alarms or faulty sensors. You’ll want to ask about how repairs work and if there’s any associated cost just in case.   

Customer support

Depending on your home security system plan, technical support can be limited. If you’re leasing the security equipment, your security provider may replace equipment. Others are able to troubleshoot over the phone or may require a technician. Some customer support is available 24/7, while others have limited hours and support contact information.


Ask about warranties in case your security system doesn’t meet your needs. Most home security system warranties range from 30 days up to a year. Look for warranties with a money-back guarantee to ensure you’re refunded as much money as possible without any hidden terms.
