When it comes to securing your home or business, choosing the right security system is crucial. Two main options are available: DIY security systems, such as Ring, Nest, SimpliSafe, and Cove, and professionally installed security systems. Each option has its own set of advantages and disadvantages. In this blog post, we will explore the pros and cons of both DIY and professionally installed security systems to help you make an informed decision.

DIY Security Systems

DIY security systems like Ring, Nest, SimpliSafe, and Cove have become increasingly popular due to their ease of use and affordability. Here are some of the key pros and cons of these systems:


  1. Affordability:
    • Lower Initial Cost: DIY systems generally have a lower upfront cost compared to professionally installed systems. They are often sold as complete packages that include everything you need to get started.
    • No Installation Fees: Since you install the system yourself, you save on professional installation fees.
  2. Ease of Installation:
    • User-Friendly: DIY systems are designed to be easy to install, with most components being plug-and-play. You can set up your system in a matter of minutes without any technical expertise.
    • Flexibility: You can install and configure the system at your own pace and make adjustments as needed.
  3. Remote Access:
    • Mobile Control: Most DIY systems come with mobile apps that allow you to monitor and control your security system remotely. You can receive alerts, view live video feeds, and adjust settings from your smartphone.
  4. No Long-Term Contracts:
    • Flexible Plans: Many DIY systems offer month-to-month monitoring plans without the need for long-term contracts. This flexibility can be appealing if you prefer not to commit to a long-term agreement.


  1. Limited Support:
    • Self-Reliance: With DIY systems, you are responsible for installation, maintenance, and troubleshooting. This can be challenging if you encounter technical issues or need assistance.
    • Customer Service: While some DIY providers offer customer support, it may not be as comprehensive or responsive as the support provided by professional security companies.
  2. Potential for Errors:
    • Installation Mistakes: Without professional guidance, there is a risk of incorrect installation, which can compromise the effectiveness of your security system.
    • Maintenance Issues: Regular maintenance and updates are your responsibility, which can be time-consuming and require technical know-how.
  3. Basic Features:
    • Limited Capabilities: DIY systems may lack some of the advanced features and integrations available in professionally installed systems. This can limit the overall functionality and customization of your security setup.

Professionally Installed Security Systems

Professionally installed security systems offer a higher level of service and support. Here are the pros and cons of choosing a professional system:


  1. Professional Installation:
    • Expert Setup: Professional installers ensure that your security system is set up correctly and optimally. They have the knowledge and experience to address any challenges that arise during installation.
    • Customized Solutions: Professionals can design a security system tailored to your specific needs, ensuring comprehensive coverage and integration with other security measures.
  2. Onsite Support and Maintenance:
    • Professional Assistance: If you encounter any issues with your system, professional security companies offer onsite support to diagnose and resolve problems quickly.
    • Regular Maintenance: Professional systems often include regular maintenance and updates, ensuring your system remains in optimal condition.
  3. Advanced Features:
    • Enhanced Capabilities: Professionally installed systems typically offer more advanced features, such as integration with other security devices, advanced video analytics, and custom alerts.
    • Higher Security Standards: These systems often meet higher security standards and certifications, providing greater peace of mind.
  4. Warranties and Guarantees:
    • Warranty Coverage: Professional systems usually come with warranties that cover equipment and installation. This ensures that you are protected against defects and issues.
    • Service Guarantees: Many professional security companies offer service guarantees, providing additional assurance of the system’s reliability and performance.


  1. Higher Cost:
    • Initial Investment: Professionally installed systems generally have a higher upfront cost due to the professional installation and higher-quality equipment.
    • Ongoing Fees: There may be ongoing fees for monitoring services, maintenance, and support.
  2. Less Flexibility:
    • Contractual Obligations: Professional systems often require long-term contracts for monitoring services, which can be a disadvantage if you prefer more flexibility. (St Louis Alarm Co DOES NOT require contracts all plans are month to month with NO contracts)
    • Dependency on Professionals: Making changes or upgrades to the system typically requires professional assistance, which can be less convenient than a DIY approach.
  3. Installation Time:
    • Scheduling: Professional installation requires scheduling an appointment with the service provider, which may result in a longer wait time compared to a DIY setup.


Choosing between a DIY security system and a professionally installed system depends on your specific needs, budget, and preferences. DIY systems like Ring, Nest, SimpliSafe, and Cove offer affordability, ease of installation, and flexibility, making them ideal for those who prefer a hands-on approach and lower initial costs. However, they come with limited support and potential installation challenges.

On the other hand, professionally installed systems provide expert setup, comprehensive support, advanced features, and warranties, ensuring a higher level of security and peace of mind. They are suitable for those who prioritize reliability and are willing to invest in a more robust security solution.
