Installing an Access Control System is one of the most effective steps businesses and institutions can take to improve security. Whether it is securing entry points, restricting sensitive zones, or managing visitor access, a reliable access control system plays a vital role. However, even the best technology can fall short if it is not installed properly.

At XTEN-AV, we help system designers and integrators plan access control solutions that are efficient, scalable, and aligned with the specific needs of each project. In this blog, we will highlight the most common access control installation mistakes and how to avoid them. By understanding these pitfalls, you can ensure that your system delivers maximum security and long-term performance.

1. Skipping a Site Survey

Before installing an access control system, conducting a detailed site survey is essential. Failing to evaluate the property layout, entry points, cabling paths, and environmental conditions can lead to costly adjustments later.

What to avoid:

• Installing readers where wiring is difficult or impossible

• Overlooking weather protection for outdoor components

• Placing hardware where visibility or reach is poor

Best practice: Always begin with a site walkthrough. Use design platforms like XTEN-AV to create accurate diagrams and plan wiring routes, hardware placement, and user flow.

2. Poor Hardware Placement

Placing card readers, biometric scanners, or keypads too high, too low, or in awkward positions makes access difficult for users. Inconsistent placement across entry points can also confuse employees and visitors.

What to avoid:

• Installing readers out of comfortable reach

• Placing biometric devices in poorly lit areas

• Blocking readers with furniture or structural features

Best practice: Follow manufacturer guidelines for height and placement. Ensure easy visibility, accessibility, and unobstructed operation at all access points.

3. Not Planning for Future Scalability

Many access control installations are designed only for current needs. This short-term thinking creates challenges when the organization grows, adds new departments, or expands to multiple locations.

What to avoid:

• Limiting the system to a small number of doors or users

• Choosing hardware that cannot be upgraded

• Installing software with user caps or restricted features

Best practice: Use a scalable solution that supports future growth. XTEN-AV helps plan systems that can adapt over time without requiring a complete overhaul.

4. Inadequate Power Supply Planning

Access control devices require consistent power to function. Failing to plan for backup power, surge protection, or appropriate voltage can lead to device failures and system outages.

What to avoid:

• Overloading a single power source

• Ignoring the need for power over Ethernet (PoE) or backup batteries

• Not planning power distribution for remote doors

Best practice: Always include power assessments in your planning stage. Consider using PoE-enabled devices and include battery backups for critical points.

5. Weak Network and IT Integration

Access control systems often rely on network connections for communication, logging, and remote access. Improper network integration can lead to slow performance, security vulnerabilities, and data loss.

What to avoid:

• Using unsecured network connections

• Neglecting firewall and VLAN configurations

• Delaying IT department involvement

Best practice: Collaborate with the IT team early in the process. Ensure the network infrastructure supports the access control system, especially for cloud or mobile-access solutions.

6. Lack of Proper Credential Management

Once the system is installed, managing access credentials becomes a daily task. If not handled correctly, expired badges, unauthorized users, or lost credentials can compromise security.

What to avoid:

• Not revoking access for former employees

• Allowing shared credentials among users

• Failing to log or audit access activity

Best practice: Set up role-based access levels and automate credential expiration. Use access logs to monitor usage and detect unusual activity.

7. Forgetting to Secure the Control Panel

In many installations, the system’s control panel or server is left unsecured or easily accessible. This creates a single point of failure where intruders could disable the entire access control setup.

What to avoid:

• Leaving panels in unlocked closets or open areas

• Using default login credentials for control software

• Failing to log administrative access to the system

Best practice: Secure all control equipment in locked cabinets or rooms. Set strong administrative passwords and restrict access to authorized personnel only.

8. Inadequate Testing After Installation

Installing hardware and software is not enough. Without proper testing, issues like door misalignment, software errors, or incorrect access levels can go unnoticed.

What to avoid:

• Rushing deployment without system testing

• Ignoring feedback from early users

• Not simulating emergency scenarios

Best practice: Test each access point under normal and emergency conditions. Validate user roles and permissions. Perform stress tests to ensure the system handles real-world activity.

9. Not Training End Users and Administrators

A powerful system is only useful if users know how to operate it. Many installations fail because staff or tenants are not trained on how to use access cards, biometrics, or mobile apps.

What to avoid:

• Leaving users confused about system operation

• Giving too many users administrative rights

• Skipping documentation or help guides

Best practice: Provide clear training and onboarding materials. Train security staff, administrators, and users on how to properly interact with the system.

10. Failing to Integrate with Other Security Systems

Access control often works best when integrated with video surveillance, alarms, and intercoms. Failure to do so can reduce the effectiveness of your security setup.

What to avoid:

• Treating access control as a standalone system

• Not linking door events to video footage

• Overlooking emergency features like lockdowns

Best practice: Use XTEN-AV to design fully integrated systems. Combine access control with other security technologies to maximize protection and streamline management.

Final Thoughts

Installing an Access Control System is not just about placing card readers or setting up doors. It requires careful planning, proper integration, and attention to detail. Avoiding these common installation mistakes can save time, reduce costs, and prevent future headaches.
