This section lists the settings found in the Analog monitor Properties tab, in the Video task.
The Properties tab lets you configure the video stream usage (or function) and specific network settings for the analog monitor.
- Stream usage
- Select the video stream to use for cameras displayed in the analog monitor. This option is only available for decoders capable of generating multiple video streams. The stream usage options are the following:
- Default stream used for viewing live video in Security Desk.
- Stream recorded by the Archiver for future investigation.
- Stream used for viewing video when the bandwidth is limited.
- Low resolution
- Stream used instead of the Live stream when the tile used to view the stream in Security Desk is small.
- High resolution
- Stream used instead of the Live stream when the tile used to view the stream in Security Desk is large.
- Analog format
- Select NTSC (National Television System Committee) or PAL (Phase Alternating Line) analog format for the video signal. PAL format generally streams video at a lower frame rate, but at a higher resolution.
- Display camera name
- Turn this option on if you want the camera name to be shown when it is displayed in the analog monitor in a Security Desk tile.
- UDP port
- Port number used when the connection type is unicast UDP. If the encoder supports multiple video streams, this parameter is different for each stream.
- Connection type
- Defines how communication is established between the Archiver and the unit for sending or receiving video streams. Each device on the same unit could support different connection types.
- Best available
- Lets the Archiver select the best available connection type for the stream. The best
available types rank in this order, according to availability: Multicast,
UDP, and TCP. When the stream is requested for recording only,
multicast is removed from the list, so the best available types start with UDP.
- Communication between a single sender and multiple receivers on a network. This is the preferred connection type. In this mode, multiple users in multiple locations can receive the same video transmission simultaneously from a same source, using the bandwidth only once. Most video units are capable of multicast transmissions.
- Forces the stream to be sent in UDP to the Archiver. The stream must be formatted using the RTP protocol.
- Forces the stream to be sent in TCP to the Archiver. Here, TCP is taken in the broad sense. For some types of cameras, the Archiver establishes a TCP connection to the unit and receives the stream in a proprietary protocol. For others, the stream is sent over HTTP. Typically, the stream is not formatted according to the RTP protocol by the unit. The Archiver has to convert the stream to the RTP protocol to be archived or retransmitted to the system.
In the Hardware section, you can associate other hardware devices (PTZ motor, Speaker, Microphone, and so on) to this analog monitor. When the decoder is added to the system, all hardware devices belonging to the same unit are configured by default. You can manually associate the analog monitor to other devices, according to how they are physically connected.
