The demandfor surveillance systems is growing, and the adoption of IP as a transportmechanism for video is ever increasing. Sony recognized this trend early on,and has been focused on developing products and solutions aligned with it.
Now Sony ispleased to announce the introduction of the IMZ-NS100 Series IntelligentMonitoring Software, which can be installed on your own Microsoft ® Windows ®server to monitor and control 1, 4, 9, 16 or 32 network cameras (IMZ-NS101,IMZ-NS104, IMZ-NS109, IMZ-NS116, and IMZ-NS132, respectively).
TheIMZ-NS100 Series is easy to use and free from complicated operation - usersfind it simple to set up connected cameras and to set frame rates forrecording. They can also easily monitor, search, and play back events withintuitive manipulation. A scalable security system can be set up inclient/server configuration using more than one server installed with theIMZ-NS100 Series and/ or using the NSR-1000 Series Video Network SurveillanceServer from Sony (which is perfectly compatible with the IMZ-NS100 Series).
This systemcan be controlled by a common user management interface, which allows theadministrator to freely set up the access level of each user. With theIMZ-NS100 Series, you can start an HD-ready video network surveillance systemin the scale and configuration that's ideal for current conditions, and expandthis system in the future.
Defined andset by the user, these filters set parameters to trigger alarms or performpreset actions if a 'virtual environment' is violated against prescribedconditions.
Thesettings for recording are also easy. If you select "Automatic ScheduleRecord", for example, you only need to input the recording duration (i.e.,the number of days that data is left in the storage area). The IMZ-NS100 Serieschecks the HDD storage area and sets the best frame rate for recording. You donot need to check the storage area in your PC or calculate the frame rateyourself.
With theuser-friendly GUI, you can use various monitoring functions with intuitiveoperation, such as drag-and-drop. You can also run a quick search, and playbackrecorded images, while monitoring.
Allconnected cameras are shown in a tree configuration in the Camera Pane. Bydragging a camera icon and dropping it onto a Monitor Frame, you can easilyview live images from a camera.
EachMonitor Frame shows the status of the video (live or recorded), and the name ofthe camera, above each video image. Up to 8 x 8 Monitor Frames can be used. Bydouble clicking a specific Monitor Frame, the display is switched to SingleMonitor Frame mode as below.
HotSpot Monitoring/Dual Monitor Support
A specificwindow in a multi-camera view (i.e., a larger window within the multi-camerawindow) can be assigned as the Hot Spot area, or a second monitor may be usedfor this purpose. The Hot Spot area is used to display an image of interest toget a more detailed view. This image can be manually selected or triggered byan alarm.
PTZ networkcameras from Sony and other supported brands can be controlled by the CameraControl pane. In PTZ Direct Control mode, when a point in the image is clicked,the camera automatically pans and tilts to make that point the centre of theimage. You can also zoom into the image simply by dragging out the specifiedarea of the image with a mouse.
The soundfrom a microphone connected to the camera can be monitored at the IMZ-NS100Series.
QuickSearch and Playback While Monitoring
If youclick PLAYBACK in the Monitor Control pane, you can play back the imagesrecorded a certain number of seconds before (this is initially set in the GUISetting menu). You can also quickly search for the recorded image by date/timesearch in the Monitor Control pane.
When analarm recording is executed, the date, time, and the camera name are noted inthe Alarm List. Simply by double-clicking a line in the alarm list, you canplay back the recorded image.
PlaybackControl and Data Export
With thePlayback Control pane, you can control the playback functions such as slow andreverse/forward. You can also export the still or moving images of yourspecified date and time to external media, such as CD-R, DVD-R, and USB FlashMemory.
The LayoutEditor is a powerful feature that creates customized site layouts and allowsthe user to insert backgrounds (e.g., a floor plan or campus layout), cameraicons, and company logos.
You cansearch for specific images by setting search conditions such as the cameraname, date, time, and the type of recording
You cansearch for specific images in the recorded video using intelligent functions.There are two types of search. Post VMD (Video Motion Detection), and VMF(Video Motion Filter). With Post VMD, you can search for images in the recordedvideo with search conditions that are set after the recording, such as specificobject movements. With VMF, you can search for images in the recorded videousing DEPA (Distributed Enhanced Processing Architecture) system features. Witha VMF search, you should record metadata with DEPA-enabled cameras during thevideo recording. For example, you can count the number of people who passed aline that is set on the screen. (Please refer to "DEPA")
Inconventional video analytic systems, the camera only sends video images torecorders, and video image analysis is processed solely on the recorder side.In Sony's DEPA system, the DEPA-enabled camera sends to the DEPA-enabledrecorder not only video images but also related metadata such as the camera ID,date/time, and information about the shot object (size and position). Therecorder checks this metadata with a search filter called a VMF (Video MotionFilter), to send an alarm signal when the metadata matches a preset conditionof the VMF. Since the partial image processing is done on the camera side, thesystem can be configured in a much simpler manner, and can be expanded moreeasily.
SearchResults by Timeline or List
The searchresult is displayed either by timeline or list. In a timeline chart, searchresults are displayed in different colours depending on the type of recording.You can easily playback video just by clicking on a specific part of thetimeline, or on the list.
There aretwo types of alarm-triggered recording. Alarm and Event (i.e., Activity)Recording. While it is important to initiate recordings based on video motiondetection or alarm signal input, it is also helpful if the user can define whatis considered an alarm. For example, a camera may be looking at an area wherethere are people moving about during office hours, but the recording of suchmotion should not be considered a true alarm; it is rather a normal event oractivity. However, such motion out of office hours should be considered a truealarm, and an action or alert needs to be initiated. The former is performed byEvent Recording and the latter by Alarm Recording. The date/time of AlarmRecording is listed in an Alarm List in the main GUI (but this does not occurwith Event Recording). Having this capability accomplishes two things. it saveson storage (with motion/alarm recording only), and reduces seek times whensearching Alarms and Events.
ScheduleRecording with Alarm Marking
While usingSchedule Recording, the time when the alarm is detected can be marked in thetimeline. This function enables images to be searched quickly.
FlexibleUser Management Setting
All accessto the IMZ-NS100 Series is managed by user authorization, which is set by thesystem administrator. The administrator can simply provide each user with apermission level selected from the five ready-made levels of operationalpermission, or set the accessibility in a more customized way. The accessiblecameras for each user can be set for each camera, or for each IMZ-NS100 Series.When the system is configured with more than one IMZ-NS100 Series and/or withone or more NSR-1000 Series of network servers, all user information is sharedthroughout the whole system.
Connectedwith Sony's major network cameras *1, the IMZ-NS100 Series can accept both JPEGand MPEG4 from cameras at the same time. With a limited storage capacity, forexample, you can monitor live video via MPEG4 at frame rates as high as 30 fps,and record video via JPEG at frame rates as low as 1 fps.
*1SNC-RX570/RX550/RX530, SNC-RZ50, SNC-DF85/DF80/DF50, SNC-DM160/DM110,SNC-CS50/CS20, SNC-CM120, and later models.
LightFunnel Control for Higher Sensitivity
LightFunnel is a technology in Sony's megapixel network cameras to provide highersensitivity. By combining the information of four pixels and handling them as asingle pixel, this type of camera provides sensitivity four times higher thanconventional cameras. With the IMZ-NS100 Series, there is a menu to control theLight Funnel settings of applicable cameras; this simplifies control. (Pleasenote that when Light Funnel technology is applied to a 1280 x 960 image, itssize becomes 640 x 480.)
