Home Size

Larger homes may need more security equipment than smaller ones, especially if your home has many windows and doorways. The best home security system has indoor security cameras, outdoor security cameras and sensors in every access point and room to prevent suspicious activity.

Bundling can save on the cost of individual security system equipment, but it will cost more overall. For example, a single Blink security camera costs $100 at the time of writing. Five cameras are $400, or $80 each.

Monitoring

Monitoring costs range from $0 to $80 per month. If you decide to monitor your security system yourself, you might not pay anything at all for this feature, depending on the company, while other companies may require you to pay up to $75 a month for self-monitoring. Additionally, if you do decide to use self-monitoring equipment, then you may need to make a one-time purchase for a local storage device. USBs or other similar hard drives cost anywhere from $5 to $50.

Professional monitoring fees start at $2.99 and can go up to $79.99 per month, depending on the features your company provides. Since professional monitoring can quickly accumulate, some homeowners like to save money on their security systems by monitoring their homes themselves.

Wireless vs. Wired

Wireless security cameras cost between $45 and $200 each, and wired security cameras cost between $35 and $120 apiece on average, making them between $10 and $80 cheaper upfront. Wired home security systems almost always cost less than wireless ones, but some wired systems require a lengthier installation process to access the electrical wiring in your home, which can end up costing more.

Installation Cost

The cost to install a security system is between $0 and $225. Your security system company may offer a complimentary installation service, but more often than not, there will be a fee for a pro to come to your home and install the system for you.

Installing a home security system can come with extra costs, like activation fees, permits and hidden fees.

Activation Fees

Some, but not all, home security companies require an activation fee to get started with their services. Fees can range from $0 to $100. Higher fees are typically due to required inspections prior to activation.

Permits

Residential alarm permits cost between $25 and $50 per year on average. If your home security system connects to emergency services as part of the monitoring conditions, then you may be required to get an alarm permit for your system.

Hidden Fees and Fine Print

You may face additional hidden fees when purchasing a home security system. A security system company may require an activation fee to receive monitoring services or a cancellation fee if you cancel before the end of a contract. Similarly, you might sign up for a promotional monitoring service that increases after a certain amount of time. Always read the fine print when deciding on a home security system to avoid costly surprises.

Installing a security system yourself can save you up to $225. However, if you want to cover the most ground and boost your security levels, a professional can pinpoint the best places to install security features and reduce the risk of user error.

The same goes for monitoring services. While you can monitor your home yourself, having an on-call extra pair of eyes keeping watch over your home adds security and reduces your home’s chances of being a victim of successful crime.

Because home security systems are such a competitive market, many companies offer similar products at different price points. Shopping around and following these tips can help you save on the cost of your home security system:

• Invest in a one-time USB storage and monitor your home security system yourself to avoid monthly monitoring services.
• Avoid purchasing security system equipment that you don’t need.
• DIY the installation by choosing a wireless system that doesn’t require professional installation services.
• Shop around for different security equipment to compare prices.
• Look for security system companies that offer flexible terms and conditions.
• For hidden fees, like activation fees and term limits, to avoid going over budget.
• Shop for older generation equipment that still functions but doesn’t necessarily have all the specs of the newest generation.
• If you want the newest generation, look at refurbished security equipment.
