# Alimenter une caméra Verkada via coaxial

Apprenez à alimenter une caméra Verkada via coaxial (PoC)

Les caméras Verkada nécessitent une alimentation par Ethernet (PoE) pour fonctionner, ce qui requiert un câble Ethernet et un switch PoE ou un injecteur d’alimentation. Pour les organisations qui disposent de caméras anciennes fonctionnant sur câble coaxial, remplacer le câblage par de l’Ethernet peut prendre beaucoup de temps. La solution est l’alimentation par coaxial (PoC), qui fonctionne tout aussi bien que l’Ethernet standard.

* Commutateur Netgear PoE/PoE+
* HighWire Powerstar (PoE/PoE+)
* Câble coaxial RG59 (300 pieds)
* Verkada D30

## Points à prendre en compte pour le PoC

Chaque liaison coaxiale nécessite généralement un adaptateur à chaque extrémité. En effet, le signal devra être converti de PoE en PoC, puis de nouveau en PoE. Si le coaxial installé fonctionne déjà en PoC, un seul adaptateur est nécessaire à l’extrémité de la caméra pour convertir le signal en PoE.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://help.verkada.com/verkada-cameras/fr/installation/camera-deployment/power-a-verkada-camera-over-coax.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
