OEM PTZ IP Cameras From China
1 resources tagged with "Ptz Cameras"
PTZ (pan-tilt-zoom) IP cameras are a strong China OEM category, with 4MP units offering 25× optical zoom, 100m IR night vision, and PoE+ (802.3at) power over a single cable. The detail buyers miss is ONVIF profile support: a camera that claims ONVIF but only implements Profile S (streaming) won't expose pan-tilt control or analytics that Profile T and G handle. True ONVIF S/T/G compliance is what lets the camera drop into an existing VMS without custom integration.
When you source PTZ cameras, verify the ONVIF profiles actually work against your VMS, not just the marketing claim — and confirm the PoE class, because 25× zoom plus IR plus motors can exceed 802.3af budgets and need 802.3at. We bench-test ONVIF control and PoE draw on samples before committing volume.

FAQ
Why does ONVIF profile matter on a PTZ camera?
Profile S handles video streaming, but PTZ control and presets need Profile T, and edge storage/analytics need Profile G. A camera advertising only 'ONVIF' may lack the profile your VMS relies on for pan-tilt control.
What PoE class does a PTZ IP camera need?
PTZ cameras with motors, IR illuminators, and long zoom typically need PoE+ (802.3at, ~25W), not standard PoE (802.3af, ~15W). Powering them on an af switch causes resets when the motors and IR run together.
