Caution
Displaying Live Video from a Specified
Angle as Still Images
By specifying the camera angle as a parameter in the HTML code beforehand, you can view the
image at a specified camera angle. The example below displays a still image shot with the
camera panned right by 40° and tilted down 10°.

Parameter
Description
p (pan)
Specifies the camera pan angle (VC-C4: -100 to 100; VC-C4R: -170 to 170; VC-C3: -90 to
90; VC-C1: -50 to 50).
z (zoom ratio)
Specifies the camera tilt angle (VC-C4: -30 to 90; VC-C4R: -90 to 10; VC-C3: -30 to 25; VC-
C1: -20 to 20).
Specifies the camera zoom ratio (VC-C4: 10 to 126; VC-C4R: 10 to 126; VC-C3: 10 to 101;
VC-C1: 10 to 74).
Specifies the backlight compensation (on: backlight compensation used; off: backlight
compensation not used).
b (backlight compensation)
Specifies the video image size (640, 320, 160 or 80).
seq
Allows any number to be specified to avoid displaying old images (numeric value).
v (image size)
t (tilt)
cache_id
Displays images cached in the server (camera number).
● If old images are displayed, you can prevent this recurring
by specifying a sequence number in the seq parameter.
● If the camera angle is specified, the image is not displayed
until the camera operation has been performed.
Consequently, on pages that are frequently accessed, user
wait time will often increase. When this is likely to occur,
specify the cache_id parameter. Images cached in the HTTP
conversion server can be retrieved without operating the
camera. (The cache is valid for one minute.)
* The underscored portion is a sample IP address. Enter the actual camera server IP address.
Also, if the camera server's HTTP conversion server port number is 80, only the camera server
host name is required. If not, you must include the camera server host port number (eg.
192.168.100.10:8080).
