Performance Series IP Camera Software Configuration Guide
The camera provides real-time H.265, H.264 and MJPEG compression standards (Triple
Codec) for real-time viewing.
•
If the H.265 or H.264 mode is selected, the video is streamed via RTSP protocol.
•
If the JPEG mode is selected, the camera sends consecutive JPEG images to the client,
producing a moving effect similar to a filmstrip. Every single JPEG image transmitted
guarantees the same image quality, which in turn comes at the expense of variable
bandwidth usage. Because the media contents are a combination of JPEG images, no
audio data is transmitted to the client.
There are several parameters through which you can adjust the video performance:
Frame size
Set different video resolutions for different viewing devices. For example, you can configure a
smaller frame size and lower bit rate for remote viewing on mobile phones and a larger video
size and a higher bit rate for live viewing on web browsers, or recording the stream to an NVR.
A larger frame size takes up more bandwidth.
Maximum frame rate
This limits the maximum refresh frame rate per second. Set the frame rate higher for
smoother video quality and for recognizing moving objects in the field of view.
If the power line frequency is set to PAL, the frame rates are selectable at 1fps, 2fps, 3fps,
5fps, 8fps, 10fps, 12fps, 15fps, and up to 25fps. If the power line frequency is set to NTSC, the
frame rates are selectable at 1fps, 2fps, 3fps, 5fps, 8fps, 10fps, 12fps, 15fps, and up to 30fps.
You can also select Customize and manually enter a value.
The frame rate will decrease if you select a higher resolution.
For 5M models, if you enable the WDR function, the maximum frame
Note
rate is 20fps.
Intra frame period
Determine how often for firmware to plant an I frame. The shorter the duration, the more likely
you will get better video quality, but at the cost of higher network bandwidth consumption.
Select the intra frame period from the following durations: 1/4 second, 1/2 second, 1 second,
2 seconds, 3 seconds, and 4 seconds.

Dynamic Intra frame period
High quality motion codecs, such as H.265, utilize the redundancies between video frames to
deliver video streams at a balance of quality and bit rate. The encoding parameters are
summarized and illustrated below. The I-frames are completely self-referential and they are
largest in size. The P-frames are predicted frames. The encoder refers to the previous I- or P-
frames for redundant image information.
