Requesting Images from Camera
The MP8D and MP8P camera supports two types of image requests: single JPEG
image requests (image or img.jpg) and motion JPEG stream requests (mjpeg).
The maximum number of supported simultaneous requests of single images or
mjpeg streams is eight.
NOTE: Even though the camera supports multi-user access, the maximum frame rate is achieved
only when there is a single request arriving to each channel at any given time.
1. Requesting single JPEG images
1.1 Requesting images using explicit parameter list within the HTTP
string:
http://camera_ip/image[<channel>]?res=(half¦full)&x0=(0..1600)&y0=(0..1200)&x
1=(32..1600)&y1=(32..1200)&quality=(1..21)&doublescan=(0¦1)&[id=(0..999999
99999999)]&[ssn=(0..65535)]
where:
res ‒ image resolution (full or half);
x0,y0,x1,y1 ‒ image cropping coordinates;
quality ‒ image quality, the inverse of image compression level;
doublescan ‒read mode (reserved for future use);
id ‒ an arbitrary number used to control the web browsers cache;
ssn ‒ a unique HTTP session number which cancels out any earlier sent
HTTP request with the same number which got hung;
NOTE: an image request without <channel> parameter specified will cause the camera to transmit
the next available image from any of the currently enabled channels. The channel number of the
transmitted image could then be identified from the HTTP header Etag (see RFC-2068 HTTP 1.1):
E Ta g: Channel<channel> .
