Operating the Camera Controlling alarm output 1 You can control Alarm output 1. To use this function, you need to make Alarm output 1 active in the Trigger menu of the Administrator menu (page 86). 1 Click Alarm output1 on the Trigger panel. The alarm output is switched by clicking. The alarm output mode can be selected from Toggle or Timer of Alarm output 1 (page 86) in the Trigger menu. Tip For the connection of peripheral devices to the alarm output of the I/O port, see the supplied Installation Manual. Controlling the Day/Night function You can set the Day/Night function to On (night mode) and Off (day mode). To use this function, you need to make Day/Night active in the Trigger menu of the Administrator menu (page 86). 1 Click Day/Night on the Trigger panel. Each click switches the Day/Night function alternately between On (night mode) and Off (day mode). Note If Day/Night mode in the Trigger-Day/Night menu (page 86) is set to Auto, you cannot control the Day/ Night function by clicking Day/Night. Playing an audio file stored in the camera You can play an audio file previously stored in the camera using the SNC audio upload tool. To use this function, you need to make Voice alert1, Voice alert2 and Voice alert3 active in the Trigger menu of the Administrator menu (page 87). 1 Click Voice alert1, Voice alert2 or Voice alert3 on the Trigger panel. Playback of the selected audio file starts and the playback sound is output from the speaker connected to the camera. Switching Transmission Mode You can change the transmission mode for video/audio data. This function can be used when Mode (video codec mode) is set to MPEG4 or H.264 and the ActiveX viewer is used. Notes • The function may not operate correctly if you use personal firewall software or antivirus software on your computer. In that case, disable the software or select the TCP mode. • If you are using Windows XP Service Pack 2 or later, Windows Vista, or Windows 7, disable "Windows Firewall". For details, see "Configuring Windows Firewall" in "When using Windows XP Service Pack 2 or later" on page 10, "Configuring Windows Firewall" in "When using Windows Vista" on page 13, or "Configuring Windows Firewall" in "When using Windows 7" on page 15. 1 Select TCP, Unicast or Multicast from the Connection drop-down list in the Others panel. TCP: This is normally selected. When TCP is selected, HTTP communication is adopted for video/audio communications. HTTP is the protocol used for reading the usual Web page. In an environment capable of reading Web pages, you can watch or listen to video/audio by selecting the TCP port. Unicast: When Unicast is selected, RTP (Realtime Transport Protocol) is adopted for video/audio communications. Since RTP is the protocol for running video/audio data, the video/audio playback is smoother than when TCP (HTTP) is selected. If a firewall is installed between the camera and the computer, or depending on the network environment, video/audio may not play back properly when Unicast is selected. In this case, select TCP. 30 Switching Transmission Mode
