Security cameras have evolved drastically over the years. Today, you can access real-time surveillance footage on your smartphone to monitor your home or business even if you’re hundreds of miles away. But the value, safety and peace of mind from installing security cameras at your business remains the same — priceless.

Your St Louis Alarm Co security camera installation will be done quickly and reliably by our team of in-house security professionals. STL Alarm Co performs high-quality security camera installation for residential, HOAs, commercial facilities, and lots or yards.

Running the cabling and mounting the IP cameras is only part of the job. Our technicians will set up and configure your system and provide onsite training as to how to use and mange the system.

We will adjust each camera at the  NVR for the best recording quality possible. If the camera comes with an internal programming capability, we will make adjustments to the camera itself. We finish the security camera installation by plugging all cracks, seams and holes with caulk (fire-rated caulk where needed) to ensure weather protection.

Commercial Surveillance Cameras

Commercial surveillance cameras are typically designed for extensive and demanding security needs. These cameras come with advanced features and higher durability to withstand challenging environmental conditions.

  • Robust and Durable: Commercial cameras are built to withstand harsh conditions and are often vandal-resistant.
  • Higher Resolution: They typically offer higher resolution for clearer images, which can be essential in identifying faces or license plates.
  • Scalability: Commercial systems are designed to handle a larger number of cameras, making them suitable for businesses with significant surveillance needs.
  • Advanced Features: These systems may offer advanced features like thermal imaging, pan-tilt-zoom capabilities, or integration with other security systems.
  • Continuous Recording: Unlike cloud-based systems that only record when motion is detected, NVRs record 24/7, ensuring you never miss any activity.
  • Reliability: With NVRs, your footage is always available, regardless of internet connectivity. There’s no need to worry about losing footage due to internet outages or slow speeds.
  • Privacy: Since the footage is stored on your own equipment, it’s not exposed to potential vulnerabilities associated with cloud storage.

Residential Surveillance Cameras

Residential surveillance cameras are designed to be used in homes and other residential properties. They are typically less expensive than commercial cameras, but they still offer a number of features that can help to keep your home safe. These features include:

  • High-definition: Residential cameras typically have high-definition resolution, which allows you to see clear images of what is happening at your home.
  • Night vision: Residential cameras typically have night vision, which allows you to see images in low-light conditions.
  • Motion detection: Residential cameras typically have motion detection, which alerts you when there is movement in your home.
  • Cloud storage: Residential cameras typically offer cloud storage, which allows you to store your footage online (requires monthly fee)

Cloud-based systems rely on your internet connection to function properly, which can be a problem if your internet is slow or unreliable. They can also carry ongoing costs for cloud storage, and potential privacy concerns as the footage is stored on third-party servers.

Does St Louis Alarm Co install residential cameras systems such as Swann or Night Owl?

While residential camera systems that can be purchased at Sam’s Club or Costco such as Swann or Night Owl may appear to be slightly more affordable than commercial-grade cameras, at St. Louis Alarm Company, we firmly believe in providing our clients with the highest quality and reliability in their security solutions. Therefore, we exclusively install commercial-grade cameras for both commercial and residential applications.

The price differential between an 8-channel residential camera system and a commercial-grade system may only be around $100. However, the installation process for both systems is virtually the same in terms of complexity and time. Given this similarity, we strongly recommend professional installation for these systems to ensure optimal functionality and performance.

By choosing a commercial-grade camera system installed by our trained professionals, you are investing in superior image quality, enhanced features, and greater durability. At St. Louis Alarm Company, we are committed to providing top-tier security solutions that offer the best value, longevity, and peace of mind for our clients.

Coaxial Cables vs. Power over Ethernet (PoE)

When choosing a camera system, it’s important to consider the type of connection the cameras use. Two common options are coaxial cables and Power over Ethernet (PoE).

Coaxial Cables

Coaxial cables are a traditional method of connecting security cameras. They transmit video signal and power separately.


  1. Compatibility: Coaxial cables can be used with older systems, making them a good choice if you’re replacing cameras in an existing system.
  2. Distance: They can transmit signals over long distances without significant signal loss.


  1. Installation: Installing coaxial cables can be more complex because it usually requires running separate power cables.
  2. Flexibility: Coaxial systems may lack the flexibility of PoE systems, which can transmit video, power, and data over a single cable.

Power over Ethernet (PoE)

Power over Ethernet (PoE) is a newer technology that allows network devices like IP cameras to receive power and data over a single Ethernet cable.


  1. Simplicity: PoE simplifies installation by combining power and data in a single cable.
  2. Flexibility: PoE systems can easily be expanded or reconfigured as your needs change.


  1. Distance: PoE can generally transmit signals only up to 100 meters, which may be limiting for larger installations. However, this distance can be extended with additional networking equipment.
