Get More From the Security System You Already Have
An existing system may still have useful cameras, wiring, sensors, readers, locks or network infrastructure. Centex Security evaluates the current equipment, the property and the results you need before recommending an upgrade, expansion or supported takeover.
The goal is a practical plan—not an automatic full replacement. When existing components are compatible, serviceable and appropriate for the project, they may be incorporated into the proposed solution.

Compatibility disclaimer: Existing equipment, wiring, software accounts and cloud services must be inspected before reuse or takeover can be confirmed. Some systems are proprietary, locked, obsolete or incompatible with current services.

Signs It May Be Time to Upgrade
- Video quality no longer supports identification needs
- Remote access is unreliable or unavailable
- The system cannot accommodate new cameras, users or doors
- Equipment is difficult to service or replacement parts are limited
- Multiple systems require separate apps or management processes
- Your current provider no longer meets operational needs
- A property renovation or expansion has changed coverage priorities
