transmitting data size and thus the network load, and a
higher frame rate is achieved.
Select On to crop the image, or Off.
Note
Object detection (page 77) operates for an image in the
image size that is not cropped even if Cropping is set to
On.
To crop an image
1
Set the Image size to 640 × 480 (VGA).
Cropping becomes active.
2
Set Cropping to On and click the Area setting
button.
The area setting window appears.
3
Click on the still image to specify the trimming
portion.
A red frame that appears when you clicked
indicates the trimming portion.
The trimming portion is determined as shown below:
To change the trimming portion, click on another
point on the image.
4
Click OK at the bottom of the window.
The cropped image is displayed on the main viewer.
5
To close the image, click in the upper-right
corner.
Frame rate
Set the frame rate of the image.
Selectable values of the frame rates are as follows.
SNC-RX570N/RX550N/RX530N: 1, 2, 3, 4, 5, 6, 8, 10,
15, 20, 25, 30 (fps)
SNC-RX570P/RX550P/RX530P: 1, 2, 3, 4, 5, 6, 8, 12,
16, 20, 25 (fps)
“fps” is a unit indicating the number of frames
transmitted per second.
Image quality (for JPEG only)
Set the quality of JPEG image.
Selectable values are from Level 1 to Level 10.
When Level 10 is selected, the best image quality is
achieved.
Bandwidth control (for JPEG only)
Limits the network bandwidth for the JPEG image data
output from the camera. Selectable bandwidths are as
follows:
0.5, 0.6, 0.7, 0.8, 0.9, 1.0, 2.0, 3.0, 4.0 (Mbps), and
Unlimited
Note
Audio may be interrupted depending on the selected
bandwidth. In that case, select a wider bandwidth.
Bit rate (for MPEG4 and H.264 only)
Set the bit rate of MPEG4 or H. 264 image transmission
for a line.
Selectable values are as follows:
H.264: 32, 64, 128, 256, 384, 512, 768, 1024, 1536
(kbps)
MPEG4: 64, 128, 256, 384, 512, 768, 1024, 1536, 2048
(kbps)
Adaptive rate control (for MPEG4 and H.264
only)
This function adjusts the frame rate and the bit rate
automatically so that the camera plays back a smooth
image to suit the connected computer environment. If
On is selected, the MPEG4 or H.264 image rate is
automatically adjusted.
Notes
• The actual frame rate and bit rate may be different
according to the image size, the shooting scene, or the
network condition.
•When Adaptive rate control is set to On, the
maximum transmission rate will be the values set in
Frame rate and Bit rate.
•When H.264 is selected and the image size is set to
640 × 480 (VGA) or 384 × 288, the frame rate used by
the camera to transmit the image will be as follows:
SNC-RX570N/RX550N/RX530N: 10 fps or less
SNC-RX570P/RX550P/RX530P: 8 fps or less
•When MPEG4 is selected, the image size is set to 640
× 480 (VGA) or 384 × 288, and the frame rate is set
to 30 fps, the frame rate may be decreased when the
bit rate is more than 512 kbps or while the object
detection function is operating.
• When the camera operation mode is set to Dual codec
and the image size is set to 640 × 480 (VGA) or 384 ×
288 in MPEG4 setting, the maximum frame rate at
which the camera can transmit data will be 20 fps.
