CCTV vs. IP vs. PoE Cameras: What Is the Difference?
CCTV describes a video-surveillance system, IP describes how a camera communicates, and PoE describes how compatible equipment receives power. They are different categories, so a system can be both CCTV and IP, and an IP camera can also use PoE.
CCTV is the system, not one cable type
CCTV means closed-circuit television. The phrase is used broadly for a surveillance setup made of cameras, recording or storage, viewing software, and network or cabling equipment. Some systems use analog cameras and a DVR; others use IP network cameras and an NVR or cloud-managed video service.
IP describes network communication
An IP camera sends video and device data over an internet protocol network, usually an Ethernet LAN. Network cameras can support remote administration, analytics, and integrations, but those capabilities vary by camera, recorder, software license, and configuration. ONVIF conformance can help interoperability; check the exact profile supported by both camera and recorder.
PoE describes power delivery
Power over Ethernet carries power and data over a compatible Ethernet cable. A PoE camera is generally an IP camera, but PoE alone does not guarantee compatibility with every switch or recorder. Check the camera’s IEEE PoE type, the switch budget, cable run, and peak power needs, especially for heaters, IR illuminators, or PTZ motors.
How to choose
For a new installation, compare total system cost, cable routes, existing coax, network capacity, recording needs, cybersecurity support, and future expansion. A qualified installer can verify the exact camera, switch, and recorder combination before purchase.
Common questions
Is CCTV the same as an IP camera?
No. CCTV is a broad name for a video-surveillance system; an IP camera is one type of camera that communicates over an IP network.
Is PoE a type of camera?
No. PoE is a way to supply power over Ethernet cabling. A compatible IP camera may use PoE, a separate power supply, or another supported method.
Can I use PoE cameras with an existing DVR?
Only if the recorder supports those network cameras and required features. Many analog DVRs do not accept IP cameras, so confirm the exact model and channel limits first.
Manufacturer documentation and further reading
Capabilities change by model, region, firmware, and software plan. Check the latest manufacturer documentation before purchasing.
