Work Experience: Minimum 3-5 years' experience producing technical/engineering drawings for physical installations - parking, security/access control, low-voltage systems, civil/site works, or a closely related technical design field - with demonstrated ability to work independently on client-facing design decisions rather than under close supervision. Produce basic on-site network diagrams for each design, showing how field devices (LPR cameras, security cameras, gates/barriers, payment kiosks, etc.) are connected on the local site LAN - typically 4-15 devices - using consistent IP addressing/naming conventions and confirming there are no address conflicts, before that LAN connects out to the server via LTE.
