Parameter Description
encode For specifying compression format. For example, specify as encode=jpeg to get JPEG.
framerate For specifying the frame rate. For example, specify as framerate=5 to get at 5 fps. Specify as framerate=-
5 to get at 1/5 fps, or in other words, 1 frame in 5 seconds. Selection range is as follows.
30, 25, 15, 10, 7.5, 6, 5, 3, 2, 1, 0, -2, -3, -5, -10, -15, -20, -30, -60
When the parameter is specified as framerate=0, VN-V25/26 sends 1 frame of JPEG data, and disconnect the TCP
connection.
1.3. Response
When API is successfully received
VN-V25/26 will return 200 OK. Content-length indicates file size of first JPEG in bytes. The x-vnv25_response line
indicates actual parameter.

VN-V25/26 has access restriction feature that enables to deny access from a specific IP address. If JPEG is requested
from the IP address of access restriction, VN-V25/26 disconnects the TCP connection after API is sent.
