Hi there,

I am very new to this forum and need your help.

I wanted to implement an external solution using the ISAPI protocol to take a current image from the HIK vision and save it to a specified location.
Of course, I also need to know under which name and in which path the image was saved in order to store this information in the external application.
Is this possible at all?

Does anyone can show me a place, wehre I can download the documentation?

Thank you really very much and have a nice day.

Figuring out Hikvision API / ISAPI

I have been using the Hikvision API on a pair of DS-2CD2345FWD-I cameras. Based on some code I found online I was able to determine how to connect, authenticate & inject a text overlay onto the camera interface. This has worked great for about 1 year, never an issue. Here is a snapshot...

This the extent of my knowledge regarding the Hikvision API:

Snapshot using HTTP URL:

http://<IP address of IPC>:<HTTP port>/Streaming/channels/1/picture​
​
To include authentication:
http://<username>:<password>@<IP address of IPC>:<HTTP port>/Streaming/channels/1/picture​

NOTES:
If the HTTP port is still the default 80 then it can be omitted from the above URL.
Also, not sure how to have it save to your specified location.

Great! Thank you.
What response do you get from the API? Is in the response the location of the saved picture and the name of the file?

If entered from a browser I believe the response is a displayed JPEG file.

I ran across something before while looking into this that may be more like what you're looking for, let me try to locate it.

Sorry, unable to locate any further info re: Hikvision snapshot API
 
There isnt one. For storing image is not really related to hikvision API(only mentioned when getting data from storage aka downloading), therefor implement saving solution as u can. One way can be using C# like i did here:

If you will use async method then File.WriteAllBytesAsync

You specify location and name yourself. Could be Cameraname_timestamp.jpg


declare camera names depending on IP address or fetch deviceInfo
timestamp can be used in a way DateTime.Now() in POST request to fetch image method.

Thank you! I would like to test it out but need a camera, which supports isapi. Do anybody know, where I can find a cam?
I have searched hole amazon and other shops but no one can give me the info, which cam supports ISAPI.

Tell me what exactly what do you need, like do you want to save image on event or simply call snapshot and have it saved to some directory or what?
 
My client buys goods from his customers. When he creates an invoice, he wants to be able to take a picture of the goods so that he can attach this picture to the created invoice. He has installed a very good and expensive HIK Vision IP cam and wants to use this camera for the pictures.
So my application should fulfill the following requirements:
  1. My application should have a button for taking pictures
  2. When click on the button a picture should be taken with the IP cam and attached to the invoice
  3. I don't want to save the whole image to keep the size of the database small. Instead, I want to save only the reference to the image in the app so that I can open the image from the IP Cam location.

    For this reason, I should know where this image was saved. Because I would take the location and the name (or ID) of the image and save it in the invoice

    Sorry for the confusion and thanks a lot for your help.

What about this short code I wrote
1693896635032.png

On browse you select desired folder, and when i press SNAPSHOT it will save the image from camera using YYYY-MM-DD_HH-MM-SS,jpg

Also a grid view of your saved images, aswell imagebox containing lastly snapshotted image

Gridbox contains ID,imagename and path you can copy



Edited: Noticed i didnt sort datatable descending, but it can be done really fast

I mean this can be upgraded to add lets say mysql database, where each data from grid will be stored in db. Then you can have the history of data. This way its only until u close the application.

Also it can be modified to support taking snapshots from multiple cameras and having imagename contain camera name. But it all depends on requirements.
