If JPEG mode is selected, the Network Camera continuously sends JPEG images to the clients, producing dynamic effects similar to movies. Every single JPEG image transmitted guarantees the same image quality, which in turn comes at the expense of variable bandwidth usage. And because the media contents are a combination of JPEG images, no audio data is transmitted to the clients.

Frame size

Select the video size. Note that a larger frame size takes up more bandwidth. The frame sizes are selectable in the following resolutions: 176 x 144, 320 x 240 and 640 x 480.

Maximum frame rate

This limits the maximal refresh frame rate per second. Set the frame rate higher for a smoother video quality.

If the power line frequency is set to 50Hz, the frame rates are selectable at the following rates: 1fps, 2fps, 3fps, 5fps, 8fps, 10fps, 15fps, 20fps and 25fps. If the power line frequency is set to 60Hz, the frame rates are selectable at the following rates: 1fps, 2fps, 3fps, 5fps, 8fps, 10fps, 15fps, 20fps, 25fps and 30fps.

■ Video quality

The video qualities are selectable at the following settings: Medium, Standard, Good, Detailed and Excellent.

Audio settings

Mute: Select this option to disable audio transmission from the Network Camera to all clients. Note that if mute mode is turned on, no audio data will be transmitted to all clients even though the audio transmission is enabled in the Client Settings page. In that case, the following message is displayed.

Input gain: There are two options for external microphone input gain, 0db and 20db.

Audio type: Select audio codec AAC or GSM-AMR and the bit rate.

AAC targets at performing good sound quality at the cost of higher bandwidth consumption. The bit rates are selectable at the following rates: 16Kbps, 32Kbps, 48Kbps, 64Kbps, 96Kbps and128Kbps.

GSM-ARM is designed to optimize speech quality and requires less bandwidth. The bit rates are selectable at the following rates: 4.75Kbps, 5.15Kbps, 5.90Kbps, 6.7Kbps, 7.4Kbps, 7.95Kbps, 10.2Kbps and 12.2Kbps.

When completed with the settings on this page, click Save to take effect.
