Getting Started

The HTTP API allows you to control the camera using a browser like Microsoft Edge or Google Chrome. You can adjust multiple settings simultaneously. This feature is documented in the CM70/CM90 series manual and also available for download from the product website.

  • Ensure the camera is powered on and connected to the same network as your computer.
  • Default IP address format: 192.168.x.xxx. Find your camera's IP under Network > Ethernet > IP Address.
  • Use a browser that supports HTTP GET (e.g., Chrome, Edge).
  • Use straight quotation marks ("), not curly quotes.
  • All API requests should follow proper URL encoding format (e.g., " becomes %22).

How to Use HTTP API

All codes in the HTTP API code list are clickable. Do NOT left-click them directly.

Step-by-Step Instructions

  1. Right-click the desired code and select "Copy link".
  2. Paste the copied link into your browser. Encoded characters like %22 for quotes are normal.
  3. Replace the IP address with your camera’s actual IP (check via Network > Ethernet > IP Address).
  4. Modify the parameters in the link according to your needs.
  5. Press ENTER. If successful, a result will appear in your browser.

Copy HTTP API link from code listPaste link in browserEdit parameters in browserSuccessful HTTP API resultFailed HTTP API result

Troubleshooting

  • Check for syntax errors and ensure parameters are within valid ranges (e.g., SRT: 0-32).
  • Remove unnecessary spaces. Use "code" instead of " code ".
  • Confirm you are using the correct IP address of the camera.

Curl

Settings can also be changed using the Windows Command Prompt and curl.

Instructions

  1. Open Notepad from the Start menu.
  2. Paste an HTTP link from the HTTP API code list.
  3. Modify the command to use curl and add --data-raw.
  4. Wrap the full command in quotation marks and double the internal quotes.
  5. Edit parameters like EmAFmode and nChannel.
  6. Open CMD, paste the command, and press ENTER.

Curl command structure in NotepadCurl response in CMD

{"GetEnv"}

You can retrieve the camera's current settings using {"GetEnv"} commands in your browser or Command Prompt.

Postman

HTTP API commands can be executed via:

  • Browser GET requests
  • Command-line POST requests using curl
  • API-testing tools like Postman or Insomnia

Example: Pan Left via Browser

To send a Pan Left command to a camera at IP 172.26.40.26 with speed 50:

http://172.26.40.26/ajaxcom?szCmd={"SysCtrl":{"PtzCtrl":{"nChanel":0,"szPtzCmd":"left_start","byValue":50}}}

Correct Quotation Encoding

Use straight quotes (", ASCII 22 encoded as %22), not curly quotes:

http://172.26.40.26/ajaxcom?szCmd={"SysCtrl":{"PtzCtrl":{"nChanel":0,"szPtzCmd":"left_start","byValue":50}}}

Expected HTTP API Response

The camera responds with JSON like:

Example of HTTP API JSON response

Example: Pan Left via cURL

Use the following command structure in CMD:

curl "http://172.26.40.26/ajaxcom" --data-raw "szCmd={""SysCtrl"":{""PtzCtrl"":{""nChanel"":0,""szPtzCmd"":""left_start"",""byValue"":50}}}"
