Security camera installation costs in St. Louis, MO range from $380 to $1,135, with an average price of $729. What you’ll pay depends on the number and type of cameras you choose, as well as the installation complexity. Overall project totals can range from $125 to $1,650, depending on system size and features.
Security Camera Installation Cost Factors
Several variables influence the total cost of security camera installation in St. Louis, MO. The number of cameras you install is the primary driver, but equipment selection, wiring requirements, and home layout also play significant roles. For example, mounting cameras on exterior siding or brick, running wiring through finished walls, or installing cameras across multiple levels can increase labor time and overall complexity.
Whether you choose a wired vs. a wireless security system also matters. Wireless cameras typically require less invasive installation, while wired systems may involve more extensive routing and configuration. Full-home security systems with integrated alarms and sensors require more setup than standalone cameras monitoring a single entry point. Placement decisions—such as covering driveways, garages, backyards, or multiple entryways—can further affect the scope of work and final project total.
Number of Cameras
The biggest factor affecting cost is the number of cameras you need. Since each camera costs between $125 and $275 to install, you will need to add that amount to your budget, in addition to the camera's cost.
| Number of Cameras | Cost |
|---|---|
| 1 | $175–$275 |
| 2 | $250–$550 |
| 4 | $500–$1,100 |
| 6 | $750–$1,650 |
If your home is particularly large or you just want to cover every possible angle around your home, you'll need more than the average four to five cameras in a security camera system.
Type of Cameras
The type of camera you choose has a major impact on cost. You can decide between a security camera or a whole-house system, as well as CCTVs versus surveillance cameras and wired versus wireless.
Whole-home systems include cameras, sensors, and alarms, which typically cost $208 to $1,090. Standalone cameras are more budget-friendly and ideal for monitoring specific areas.
CCTV systems, short for closed-circuit television, use wired connections for live monitoring and are less vulnerable to hacking, but they’re not as common in homes. They also offer lower resolution. A four-camera CCTV system costs $600 to $1,600. Modern surveillance cameras connect via Wi-Fi or Power over Ethernet (PoE), offer higher resolution (including 4K), cloud storage, and motion detection. A four-camera setup runs $500 to $1,500.
Wireless cameras are the most affordable, ranging from $25 to $250 per camera, and often include advanced features like night vision and app integration. Wired cameras cost $150 to $500 each, offer stable connections, and can connect to DVR systems for secure recording.
Security Camera Installation Pro Costs
Many security camera installation professionals in St. Louis provide project-based pricing rather than hourly rates. Because total costs vary widely—from $125 for a simple setup to $1,650 for larger systems—pricing is typically determined by the number of cameras, equipment type, and installation complexity, rather than a flat hourly charge.
Requesting a detailed quote helps clarify what’s included in labor, equipment setup, and system configuration.
Do Security Cameras Increase Home Value?
Security cameras can contribute to a St. Louis home’s overall return on investment by increasing perceived safety, modernizing the property, and appealing to buyers who prioritize smart home features. In competitive markets, installed security systems can help a home stand out, particularly when they include visible exterior cameras and mobile monitoring capabilities.
Beyond resale positioning, some homeowners may qualify for discounts on homeowners insurance policies when professionally installed systems are in place. Over time, the combination of deterrence and potential insurance savings can help offset installation costs.
A professionally installed system also protects the investment itself—ensuring proper wiring, placement, and integration so the equipment functions reliably for years to come.
