The Most Common Security Mistakes in Commercial Buildings

Most commercial buildings rely on outdated or poorly configured security systems without realizing the risks. In this post, we break down the most common issues we see during site assessments. The first is camera placement: many systems have blind spots or cameras pointed at the wrong areas, making footage useless when it matters. The second issue is network configuration. Security devices often share bandwidth with guest Wi‑Fi or office traffic, creating performance problems and vulnerabilities. The third issue is access control. We frequently find doors that don’t log events, outdated card readers, or systems that aren’t integrated with the building’s network. Finally, many buildings lack proper monitoring or fail to maintain their systems, leaving them exposed. By addressing these issues, organizations can significantly improve their security posture without replacing their entire system. This post gives practical, real‑world advice based on what we see in the field every week.
