Administrator – a user that configures Wisenet WAVE.

Archive – video and audio data recorded from cameras.

Aspect Ratio (AR) – image dimensions shown as height:width. Most commonly used are: 4:3 and 16:9.

Bitrate – number of bytes per second. Used to measure video stream.

Client – the software used to connect to servers and view video streams.

Codec – video or audio compression.

Dual Streaming – enables a camera to provide two separate streams simultaneously, yielding bandwidth and processor savings on Client (see RADASS).

Export – allows to export a video footage from archive. Exported video can be viewed on any device.

FPS – Frames per Second. Used to measure video stream.

GPU – Graphic Processing Unit. The processor installed on the video card.

HTTP – Hyper Text Transfer Protocol. Some cameras use this protocol to stream video.

Item – video or image in layout.

Layout – saved video items and their position, size and orientation.Used to present surveillance information to Wisenet WAVE user.

Live – ability to view cameras live in real-time mode.

Motion Detection – indicates whether or not any motion occurred within a camera's viewing zone.

Motion Mask – the area in viewing zone that does not trigger motion detection.

Multi-Video Export – an ability to backup several videos in a proprietary format or executable bundle.

NVR – Network Video Recorder. An NVR is a software program that records video that is encoded and processed in-camera and streamed over a network to a storage device.

ONVIF – a unified protocol used for communication with cameras. See http://www.onvif.org/.

OS – Operating System.

Owner – an initial user with full access to Wisenet WAVE (his login is admin). This user cannot be deleted.

Preview Search – breaks down a period of time into smaller video segments. Example: a month broken into ten 3-day periods displaying them as separate video segments. Eases search of large archives.

Private (cameras) Network – the network used to transmit data from cameras to server. It is not accessible from outside.

Public (Intranet) Network – the network used to connect to server from outside. May be used for either connecting server to server, or configuring server components. It may or may not be connected to the Internet.

Public IP – IP Address that can be accessed from the Internet.

PTZ – Pan, Tilt, Zoom (a camera must support PTZ for this feature to be valid).

Resources – cameras, servers, local video files, users and layouts.

RADASS – Resolution and Algorithmic Data Adaptive Scaling System. Enables dynamic switching of resolution to yield bandwidth savings and optimize processor load. Requires dual-streaming to be supported by the cameras used.

RTSP – Real Time Streaming Protocol. Some cameras use this protocol to stream video.

RTSP Port – the port used by server to process requests for media streams from Wisenet WAVE Client.

Server – the computer that Wisenet WAVE server is installed on.

Server Port – used by server to process requests for recorded fragments and video data from Wisenet WAVE Client.

Smart Motion Search – an ability to search by motion within the selected range. Wisenet WAVE will provide fragments with motion occurred in the specified region.

Sync – ability to play back several cameras simultaneously.

Thumbnails – small snapshots of recorded footage used in searching.

URL – Uniform Resource Locator is a specific character string that constitutes a reference to an Internet/Intranet resource. Used to establish connection to server.

Viewer – a user with a limited access to Wisenet WAVE (not permitted to change configuration).

Watermark – used to check validity of exported files. If a file was modified or altered in any way, watermark will fail.
