Before You Buy a PoE Switch for CCTV
Check PoE budget, port count, uplinks, spare capacity and cabinet layout before buying a PoE switch.
Practical rule: Do not buy from a product title alone. Match the product to the wiring method, power requirement, cable distance and site use case.
Pre-purchase checklist
- Confirm the exact wiring diagram that applies to your site.
- Check power requirement, voltage, PoE class or current draw.
- Check cable distance and whether voltage drop or network limits apply.
- Allow spare capacity for future expansion.
- Read the installation manual before finalising accessories.
