NVR Software - SeeTec Surveillance
81
The transfer modes depend on the camera type and the differences are as follows:
Motion JPEG
:
HTTP Server Push: Communication between the SeeTec server and the
camera and the image transfer from the camera to the SeeTec server occurs
via port 80 (TCP) or HTTPS encrypted (port 443, TCP). The ports may be
changed.
MPEG-4/H.264:
RTP over Unicast (default)
: Communication between the SeeTec server
and the camera occurs via TCP port 554 (= RTSP port). The image transfer
from the camera to the SeeTec server occurs via a negotiated UDP port.
RTP over Multicast: Communication between the SeeTec server and the
camera occurs via TCP port 554 (= RTSP port). The image transfer occurs
via a multicast address that is communicated by the camera. RTP over
Multicast should only be used if third party systems and the SeeTec server
access the camera at the same time.
RTP over RTSP over HTTP: Communication and image transfer occurs via an
HTTP tunnel (port 80 TCP). This setting is recommended in case of a poor
network connection between the SeeTec server and the camera. The
drawbacks of this transfer method are possible latency times because faulty
data needs to be transferred repeatedly.
For Motion JPEG / MxPEG streaming the following applies (standard and
alarm recording):
1. Use
Frame rate
and
Resolution
to determine how many images per second
are displayed and the size of the images.
Use the
Compression (%)
field to change the actual image size (size in KB) and
resolution of image details in percent. The higher the compression percentage, the
smaller the image size. However, the resolution of image details will decrease in
individual frames. We recommend setting the compression to at least 50 % since a
lower image compression ratio could lead to server overload when writing the
images in the MultimediaDatabase.
