INTRODUCTION
Purpose of This Manual
This Manual describes the instructions and programming codes of the HTTP API functionality of the CM70 camera,
which you could use to control the camera over IP.
Target Audience
This manual is developed for IT professionals who are responsible for operating the Product.
Document Structure
The Manual is subdivided into the following Chapters:
1. Introduction
2. Appendix C - HTTP API
4

APPENDIX C - HTTP API
With the HTTP API you can control the camera by using a web browser like Microsoft Edge or Google Chrome. It
is possible to change multiple settings at once using this feature. This document is available as an Appendix in the
CM70 series manual and as a separate document that can be downloaded on the product website.
How to use HTTP API
All codes in the HTTP API code list are clickable. Do NOT click left on these codes!
Follow instructions below:
1. Click right and click (left) to COPY the link.
2. Paste the link in your browser like this (Note that all the brackets are replaced by percentages. This is
normal, ignore it):
3. Note that the IP Address in this link is an example of an IP address. Change this IP Address to the one
you use for your camera. See Network > Ethernet > IP Address.
4. Change the settings in the link. In this case:
5. Press ENTER. If correct, you get in return:
If failed, you get in return.
6. In case of a failed return, check the following:
• Syntax errors in the code/ correct numbers in the key values. Some camera settings are having
a specific range. The SRT key for example has a range of 0 - 32. If you have typed 33 it would
exceed the range of this key.
• No long white spaces between the key values of the code. For example this " code " is error and
this "code" is right.
• If you have entered the correct IP address of the camera.
7. If you have done it correct, you can check the settings you have changed in the WebGUI of the
camera.

Curl
It is also possible to change the camera settings at once by using the Command Prompt from Windows.
Follow instructions below:
1. Click on Start in the left corner of your screen in Windows.
2. Type Notepad and open this application.
3. Copy and paste the following http link from the HTTP API code list (for example: http://192.168.5.126/
ajaxcom?szCmd={"GetEnv":{"VideoParam":{"nChannel":-1}}}
4. Type curl, change the default IP address in the IP Address of your camera, and surround it by
quotation marks.
5. Add --data-raw between the http link and the code.
6. Type szCmd and surround it by quotation marks.
7. Double the quotation marks between the brackets! See the example below.
8. Modify the parameters in the code. In the example above EmAFmode:3 and nChannel:0 See the
HTTP API code list.
9. Click on Start in Windows again, type CMD and press Enter.
10. Copy and paste the link/ code from notepad in Command Prompt and press Enter. If correct it
returns: {"nRetVal":0, "szError":""}
{"GetEnv"}
You can use the HTTP API to display the current settings of the camera in your browser or in the Command Prompt
application. You need the {"GetEnv"} codes from the HTTP API code list to do this. If correct you see the following in
your webbrowser, or in Command Prompt:
