Use cases

• Commercial retail, offices and SME sites requiring consolidated PoE power and recording for up to 16 cameras.
• Installers and security contractors: rack‑mountable 1.5U form factor makes it straightforward to integrate into server racks.
• System integrators: supports ONVIF and common analytics (motion, intrusion, line crossing, people counting, ANPR where camera supports it).

Safety & compliance
Installation should be carried out by a qualified installer in accordance with local regulations and electrical code. Verify applicable approvals (CE/UKCA) for your region before purchase — see official datasheet or contact the manufacturer for certification details.

Notes
Specifications such as PoE per‑port limits, exact decoding table and regulatory approvals are available in the official datasheet and user manual. If you require a verbatim extraction of those tables, supply the PDF and I will extract the lines.
