Introduction

The Control Center Software is a part of a complex system using server-client architecture, which provides general supervision tasks of the devices developed and produced by STP.

 

By this software the image of cameras, connected to SComplex, Walk-DVR and the Logipix signals can be displayed, and outputs can be controlled.

 

It is appropriate for archiving the video stream, playing the recordings stored on the device and modifying the recording settings of the cameras.

 

Functions of the Control Center

Video Display

Playing Live Image

For displaying we can arrange camera images into monitor profiles. Camera images from different devices can be arranged to the same monitor profile as well. There are several ways to set camera images to the monitor profiles. Images are retrieved only at the size required for the display.

 

A zoom object can be placed on the monitor profiles showing continuously the image of the selected camera, usually in higher resolution. Via zoom object a LogiZoom function is available that helps retrieving the image of a selected area of the Logipix camera in higher resolution while the unselected area stays retrieved from Logipix NVR in original resolution. This method allows a much smaller bandwidth for displaying the camera pictures of the system than continuously retrieving full size images.

 

PTZ cameras can be controlled on this same interface by clicking on a certain point of the image. The software will take that to the center (the camera turns to it), and for zooming the scroll of the mouse can be used. By selecting the PTZ camera, the pre-selected prepositions appear, and by clicking on them the camera turns to the specific position.

 

Capture-camera locations may be positioned on the monitor profiles. Capture function provides that in case a given event the image of a specified camera is displayed on the recording at the emergence of the event. Thus the recording at the emergence of the event and the live image of the same camera is put next to each other, which makes the evaluation and managing the situation easier. The image of the Capture-camera, according to the settings, disappears from the monitor profile after acknowledging the event, or it is simultaneously put to a download store.

 

Control Center software may run on several locations which may have different bandwidth towards the devices. There is possibility of using only a part of the entire bandwidth for the Control Center software. You may set a bandwidth limit for every supervisory location which is adapted by the client software for every monitor profile.

 

Not only the display of the camera images is available on video monitors, but also several interventions. For example an intervention is activating the playing of the pre-recorded sound in the device, some others are activating the reflector connected to the device, or opening the SComplex entering point which belongs to the camera image. This can be handled fast and simple by the controlling icons that appear on the camera image.

 

If several Control Centers are running in the system, the VideoProxy service is suitable to use. In this case the client programs are running on several workstations turn to this module for requesting video image retrieving requests, and the VideoProxy will retrieve the images. In case the same image is required from several workstations, the image is retrieved only once from the device. This solution discharges the device and the network. Moreover, VideoProxy is provided with a short term cache which serves archiving requests from the recent past.

Playing the Archives

In case of watching on-line archives, we can display video images from several devices on one screen, thus situations can be investigated more effectively. Searching among cameras is easy with the built-in filter, which allows to search by camera name and by recording device as well. Searching recordings for on-line playback is time-based (starting and ending time). The selected period can be played forwards or backwards, with normal or higher speed and it can be stepped or paused. Logi-Zoom function for Logipix cameras is available on this interface. When selecting a camera, the activity diagram of the activity detection in the selected period is displayed, which may accelerate identifying the requested situation.

 

If saving one frame is sufficient, it can be easily saved from the paused archive (with captions like camera name, time, etc., or without them). If the download of the full retrieved period is required, then it may be forwarded to the Download Manager.

 

Beside time-based downloads, downloading log events of selected cameras for a given period is also available. Thus activities on specific entry points can be rapidly and easily controlled on a video recording.

Downloading

Recordings are stored by the Download Manager in the Download Storage on the server, retrievable by any Control Center software. Downloaded recordings may be filtered, ordered and required recordings can be played back or saved to a specific supervisory computer. At playback, the logged events which belong to the recording are listed beside it.

 

Download may also be started from the Download Manager, but besides setting the download storage space, copying specified recordings to the CF card of a Walk-DVR-CF is also available. Recordings saved to the CF card can also be downloaded, displayed and archived here.

 

Besides manual downloading, started by the user, the system can also perform event-conducted or timed download of the recordings. Downloads are accomplished by a strong Download Manager server module, capable to manage connection interruptions and small bandwidth download channels as well.

Camera Configuration

The camera configuration interface of the Building Supervision provides the setting of recording parameters and activity sensing areas for analogous cameras. It allows to set specific parameters of Logipix cameras and the detailed parameterization of PTZ cameras.

 

Setting the recording parameters includes the adjusting of recording speed and resolution, as well as the compression rate of the images. Parameters can be set separetaly for active (motion) and inactive (motionless) states.

 

Three different areas and a background can be set for activity sensing. The sensitivity of the three areas and the background can be set. Sensitivity settings will determine whether selections will be motion-sensible or those will appear as masks in front of a motion-sensible background. Activity detection may cause alarm, may change recording parameters and may appear in the Zoom window as well.

 

According to the state of the activity detection we can distinguish active and inactive states that can be set for different recording speeds, resolutions and compression rates. Thus storage capacity may be exploited effectively.

 

Settings of the high resolution Logipix cameras take effect on both the recording parameters and the images provided by the camera (light and color adjustment parameters, shutter and amplifying, mirroring, etc.). With this type of camera the masks of activity sensible areas and two further masks may be defined: exposition and sustention masks. Exposition mask defines an area that the light compensating algorithm disregards. Sustention mask is an area where both the live and recorded image parts are blank, thus areas under prohibition of observation according to legal regulation may be blocked out.

 

The settings of PTZ cameras exceeds simple recording settings. This means that besides RS-485 communication parameters of the camera (control line, control address, camera type), even prepositions can be set. From the set prepositions we can arrange tours. We can adjust what time should a camera spend on a given preposition and what speed should it spend switching from one position to another (area between the two positions should be swept or switch over should be the fastest as possible). The tours may be timed for weekly periods, but for less calculability we can set random shifting.

 

Display of the Event

The elements of the system may be traced visually by map displaying module of the Control Center software, and its outputs can be controlled. Besides altering the icons, the events appear in a text list as well.

Map

Building Supervision software can display the state of the devices of the system appearing as icons, in front of an optional background and on a map. A map is an image file (bmp or jpg), and its details can be displayed on synchronized blow-ups on sub maps. If the maps are synchronized, state elements are sufficient to be displayed on just one map. The synchronizer will help to display them on the other maps in the appropriate position. State items can be displayed on different switchable layers, in different size for every enlargement, thus enhancing the transparency of the maps.

 

The icons of certain elements show the state of the given item. By clicking on them their detailed data are displayed, by double-clicking on them the default action belonging to the item is executed (e.g.: in case of a door, the door opens). By clicking with the right mouse button, all the possible actions belonging to that specific item appear in a pop-up menu.

 

Cameras and monitor profiles can be placed on the map, thus using the Building Supervision in two monitor mode, the Video Display module may be managed by the icons on the map.

Event Grid
Events emerged in the system can be traced in the event grid. Displayed events can be filtered, colored and prioritized in the purpose of better transparency. Events may be automatically interrupted (e.g. normal entry) or can be interrupted by intervention (acknowledgement). Acknowledgement is logged together with the name of the operator, to be retrieved later.
Guard Log

Detailed comments may be attached to certain interventions by using the guard log. Using this module allows manual registering of events not emerging from the system. The prepared templates fasten and simplify the usage for operators. The built-in open word search will help auditors efficiently for searching up events.
