Camera settings

ConnectPort X Family products support connecting a WatchPort

Camera to one of its USB host

ports. One Digi WatchPort V2 USB camera is supported.

Camera settings

These settings configure the camera operation and handling of images captured by the camera.

 Enable Camera: Enables and disables camera. When disabled, all camera activity stops

and all used memory is freed.

 Resolution: The resolution level for images.

 Frame Delay: The minimum time between frames in milliseconds. The actual delay

time between frames will be this number or greater. The camera automatically increases

this value as needed, such as in low light conditions. This delay time is the inverse of

frames per second. For instance, if you wish to set the camera to process at a maximum

of 5 frames per second, the frame delay is set to 200 (1/5 = 0.2 second = 200 ms).

 Quality: Image quality. Choose a quality from 0 to 100; with 0 being the lowest quality

and smallest image sizes and 100 being the best image quality but largest image size.

Qualities ranging from 30 to 80 are recommended. Quality above 80 results in much

larger images than lower qualities, which result in lower overall performance and

increased memory use.

 Send Images to TCP Server: Enables sending camera images to a TCP server. The

TCP server application must conform to the protocol sent by this device, which is: on

connect, the TCP client sends a protocol id of four bytes: 0x85ce4a71, followed by a

protocol version of 4 bytes: 0x00000010. After this, images are sent repeatedly in the

form of 4 bytes containing the length of the JPEG image to follow, and the JPEG image.

– TCP Server: Name of the server to receive image data.

– TCP Port: TCP port. The default port is 22222.

 Current Image: Displays a snapshot of the current camera image. Clicking on the

image displays a new window with the full-size image (as configured above). If No

Camera Available is displayed, the camera is disabled (see above), no camera is

attached to the device, or some other problem is causing the camera to work incorrectly.

This current snapshot can be accessed by any web browser directly by using the URL:

http://device-ip/FS/dev/camera/0

 Advanced Settings: All settings from Automatic Gain Control on are advanced camera

settings. Leaving these camera settings at their defaults. is recommended. Advanced

users can modify them as needed, but most users do not need to modify them.

Camera operation

Once the camera is connected and configured, the current snapshot image from the camera is

available directly from the device at the following URL:

http://device-ip/FS/dev/camera/0

Video from the camera is available by streaming the camera data to a TCP server application, a

configured by the Send Images to TCP Server configuration settings. For more information, see

the Installation Guide for your Watchport Camera.
