3-2. Camera stream / Video quality setup web page

In this Stream setup page, you can set up your camera’s Primary stream, Secondary stream and Mobile stream to adjust the video quality. When the camera detects valid images, the digital image processing chip in the camera will divided the image into 3 streams automatically: Primary stream, Secondary stream and Mobile streams. The primary stream is the best quality image, Secondary stream’s image quality and image size is not as good as the primary stream. and the Mobile stream is used for old smart phones and it seldom to use now.

See the Camera Stream web page

See the mean of each parameters:

Preset: You can choose low bandwidth, generic bandwidth, better bandwidth, great bandwidth and perfect bandwidth from the “Please choose bandwidth status drop down menu“. The camera will allot value to every parameters according to your choice.

Image size: The size of video image. E.g: Is that 1280*720P, which means its horizontal pixels are 1280 and the vertical pixels are 720it is a high definition, and its total pixels are 921,600.

Frame rate: Also known as frame frequency, is the frequency (rate) at which an imaging device displays consecutive images called frames. Frame rate is expressed in frames per second (FPS). A high FPS will make live view and recording video becoming smooth but will take more bandwidth.

H.264/MPEG4 bitrateIs a video coding format that is currently one of the most commonly used formats for the recording, compression, and distribution of video content. This is the important parameter to affect the video quality, a high H.264/MPEG4 bitrate will improve the video quality to better. But a high H.264/MPEG4 bitrate will make live view and recording video becoming smooth but will take more bandwidth.

*Please note that Image size, Frame rate and H.264/MPEG4 bitrate are the 3 factors to affect video quality and video fluency.

MJPEG quality: Is a video coding format and it seldom to use now. The default value is 50% that means the Compressing Ratio is 50%. The chosen range is from 20 to 100.

JPEG snapshot quality: Set the quality of snapshot. The default value is 90% means the picture quality is compressed to 90% when snapshot camera.

Audio: The sampling method for audio. Titathink camera is used AAC-LC as sampling method, and there are 4 sampling rate for your choice. Respectively is 16Kbps, 24Kbps, 32Kbps and 48Kbps. The higher sampling rate means the better sampling audio quality. But you should match up the microphone’s sampling rate when you are using an external microphone.

Authentication: Set the video stream as an authenticated video stream or an unauthenticated video stream. The authentication enabled is recommended.

Pre-record: Titathink Camera buffer a 5-10 seconds pre-record stream. This stream can be record to SD card or NAS, it also can be remote playback via RTSP protocol. This feature allows users to review what occurred in those vital moments before the camera was triggered. There are 4 options for your choice: “Diable”, “3 seconds”, “5 seconds” and “10 seconds”. The 5 seconds is chosen by default.

Pickup RTSP URL or HTTP URL or RTMP URL for Internet stream and Intranet stream

Click the blue links “Primary Stream” or “Secondary Stream” or “Mobile Stream“, you could pickup the Internet/Intranet stream URL of each stream. See the screenshot above.

You can pick up RTSP or HTTP or RTMP URL from this web page. These URL can be used to Third-Party software such as ALC, Synology devices.

Intranet stream URL is only used for local area network. It would be un-accessed when you are trying to access it remotely.

Internet stream URL is only available when the router supports UPnP function. If not, you may get a list as below:

Both your camera and accessed device are in a same local area network, you could not access the Internet URL. Please use Intranet URL.

FAQ for video quality

Question 1: How to make the video quality better.

Answer: You can adjust the Image size and Frame rate and H.264/MPEG4 bitrate to a higher value if your bandwidth is enough.

Question 2: Why my live view becomes slack after I adjust Image size and Frame rate and H.264/MPEG4 bitrate to best?

Answer: That means your bandwidth is not enough to carry such a video streaming. You can upgrade the bandwidth or reduce the video size by adjusting Image size to keep a smooth video. Or you can also lower the H.264/MPEG4 bitrate.

Question 3: How to improve the fluency of live view without making the bandwidth heavy?

Answer: Keep the Frame rate to highest value, and then you can upgrade the bandwidth or reduce the video size by adjusting Image size to keep a smooth video. Or you can also lower the H.264/MPEG4 bitrate.

Question 4: Why the Frame rate can not reach the value I assigned?

Answer: This case is caused by the H.264/MPEG4 bitrate. Try to lower H.264/MPEG4 bitrate, the frame rate can reach the value your assigned, but please note the Frame rate in actual use is frequently changed according to the picture complexity. E.g: You set the Frame rate to 30fps, but in most of the time, it’s hard to reach 30fps. Most cases it will change in the region of 15fps to 28fps.
