media.codec.resolution (Read resolution)
media.codec.resolution: Read resolution
media.codec.resolution · Channel scope · Permission Config
What it does
Reads the resolution list on this channel (struct array, up to 100 entries; fields below). Not the StreamResolution three-preset scalar enum; if the model binds StreamResolution/17000, use capability discovery (initial leaf may be resolutionRatio/113700).
Request URL
POST https://openapi-[DataCenter].easy4ip.com/openapi/v2/device.property.get
Minimum permission
The administrator does not need an extra permission on a device they bound. A shared device needs the basic configuration permission. A bound sub-user does not. A sub-account needs Config. Omitting channelId on a channel-scope capability returns DV2007. Mixing device and channel in one request returns DV2008.
Request parameters
| Name | Type | Required | Description |
|---|---|---|---|
token | String | yes | Administrator, sub-user, or sub-account accessToken |
deviceId | String | yes | Device serial number |
productId | String | no | Optional. If sent and it does not match the device model → DV2009 |
channelId | String | yes | Channel ID; "0" is common on IPCs |
