How to pull images off LTS LTN8916 cameras via HTTP

[horseflesh]

I have the LTS LTN8916 NVR, and finally figured out how to pull still images off the connected cameras.

The manual shows this format:

However, that's for direct IP access, and my cameras are behind the NVR, and on a different subnet. They can supposedly be directly reached with the "virtual host" feature, but I could not make that work to fetch pictures.

After wandering around some other Hikvision NVR threads, I stumbled on an incantation that lets me pull images off the cameras, even though they are behind the NVR.

Low-resolution
http://NAME:PASSWORD@NVRip/ISAPI/Streaming/channels/201/picture

High-resolution
http://NAME:PASSWORD@NVRip/ISAPI/Streaming/channels/201/picture?videoResolutionWidth=1920&videoResolutionHeight=1080

• "201" is the channel number, and the "01" is disregarded, as far as I can tell. So, 201 - 299 would all retrieve the image from camera 2.
• Presumably you can adjust the resolution numbers to something higher, supported by the camera.

If anyone knows additional parameters that may be useful please share!

With Hikvision NVR PoE-connected cameras, direct access is possible via this method :

That is a handy technique, thanks. I may be able to get by querying the NVR.
