detection.counting.picPage (Feature image paged query)
detection.counting.picPage: Feature image paged query
detection.counting.picPage · Channel scope · Permission Config
What it does
Page through feature images on this channel. Inputs start (0–255) and count (1–255); returns totalCnt (up to 10000) and picInfos. When totalCnt exceeds count, increase start with a fixed count to page; the product of start and count is still bounded—narrow the time range or use device-side filters if you cannot fetch all records at once. One invoke runs one action.
Request URL
POST https://openapi-[DataCenter].easy4ip.com/openapi/v2/device.service.invoke
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. A timeout does not mean the operation did not run.
