Works for both DIY installers and professional integrators; for commercial installations use a qualified installer to ensure correct mounting, cabling and network configuration.

Compliance & safety
Check local regulatory approvals and certifications for your market before purchase. Ensure installations comply with local electrical and data regulations. Power and network connections should be handled by a competent person; if using PoE verify switch/injector 802.3af compatibility.
