Case Study: Calcasieu Parish Sheriff's Office achieves faster responses and streamlined dispatch with Tyler Technologies' Enterprise Public Safety

CalcasiParish Sheriff’s Office - Customer Case Study

Calcasieu Parish Sheriff’s Office in Lake Charles, Louisiana (serving ~203,000 residents with about 774 staff and 14 dispatchers) was hampered by an outdated CAD system that lacked embedded NCIC access, mapping, and modern dispatch tools, leaving the agency with only one terminal for background checks and limited response capabilities.

In 2007 the parish implemented Tyler Technologies’ Enterprise Public Safety suite, adding Enterprise CAD with built-in NCIC, mapping, two-way communications, and mobile self-dispatch. The upgrade streamlined call-taking, improved dispatcher–officer communication, gave faster access to mission‑critical data, sped officer response times, and proved resilient during major events such as Hurricane Laura.
