Embedded HTTP server
Firmware 1.3.0 introduces the possibility to control the camera and to visualize acquired images using
a standard web server (tested on Firefox, Chrome, …)
When the camera is connected using a gigabit ethernet network, the server is able to display up to 25
frames per second in full sensor resolution (640x512).
The server allows to configure main acquisition parameters (acquisition frame rate, exposure duration,
cropping, conversion gain….). The camera state is also monitored (status, temperatures….). A console
is also available to send commands that are not directly available on the web page.
Image statistics (histogram, standard deviation) are also computed on the fly.
The HTTP server is controlled using exec httpserver start and exec httpserver stop
commands.
Once started, the http server is listening on port 8888.
For security reasons, the HTTP server requests a login/password to allow access to the camera. The
login is adminnc. The password is the current password set in the camera (can be read using the
password” command). The password can be changed by the user.
Note: The HTTP server must be restarted after each camera reboot.
