Security with 360° Video Surveillance

Use of the eneo Almira Camera in the Jewish Museum, Frankfurt

The Jewish Museum in Frankfurt is one of the three major Jewish museums in Germany.  Prior to World War II the city of Frankfurt had the highest percentage of Jewish inhabitants with over 26,000 Jewish citizens. 

The open character of its internal architecture was intentional, and gives the sense of  accessibility to all interested visitors.  However, owing to its subject matter, the museum - housed in two classical mansions - is a high risk target for vandals, terrorists and the like .  This creates a balancing act that requires exceptional understanding from decision makers when it comes to security precautions.  The building is necessarily secured by 360° video surveillance.

Blind angles caused by concrete columns in the foyer

One particular security problem stems from  the solid reinforced concrete construction of the building.  Several concrete columns in the entrance area obstruct viewing and present practical barriers to the installation of a video surveillance system suitable for identification of visitors.

Thomas Sittig, Technical Director of the Museum and responsible for security, noted: "In addition to appropriate checks of baggage and persons we have been using video surveillance since the opening.  However, we encountered some difficulties in extending the existing system in the sensitive entrance area - on the one hand some areas of the foyer are difficult to view, and on the other hand the cable routing was made difficult because of the reinforced concrete and it is not possible to put it under plaster.″

Perfect solution replaces several cameras

In the planning phase, Peter Kleist, Project Manager of Heer GmbH from Frankfurt, proposed a solution with 360° video surveillance: "The floor plan would have made at least five or six conventional surveillance cameras necessary to cover all the angles.  But when we then considered the Almira System with its four virtual cameras, it immediately awakened great interest!″ 

The special lens of this ultra wide-angle camera delivers a 360° image field: with the "Almira C-1202" up to four virtual cameras can be displayed and controlled with full Pan/Tilt/Zoom functionality.  The system is installed at a three-metre height so it can be seen and has the whole foyer in view.  In addition, its high-resolution 3-megapixel CMOS sensor delivers brilliant quality pictures to the full satisfaction of viewers when they view the 42" plasma monitor in the control centre.

3 megapixels for clear and sharp pictures

The Security Officer can now choose between 2 x 180° panorama, 4 x 90° panorama or 360° views, and use a Videor KBD1 Keyboard to control the camera and all the fully electronic PTZ functions.  At the same time, people entering a predefined area can be tracked automatically by the "Motion Tracking" function.  "Features such as the integral motion detector, 4x zoom and intelligent alarm management are very helpful for us.  In particular the retrospective motion tracking, or the "Luggage Left" function that allows objects to be monitored in predefined areas.  The system immediately triggers an alarm when an exhibit is removed or, for example, an unattended bag is added," explained Sittig.

High-resolution 360° recording

The 360° camera images are recorded by the "Almira R-01" Network Recorder which is matched to the Almira Camera.  Peter Kleist explained: "The recorder is connected over a high-speed data link and we installed it behind one of the columns.  It provides the advantage of also allowing execution of the full functionality of the 360° camera with a digital recorder - including the PTZ functions for the recorded pictures."

"Recording can be carried out controlled by events or time or also continuous; the 400 GB hard disk permits a recording time length of up to several weeks.  Furthermore, duplex operation allows simultaneous recording and replay.  In addition, it has extensive search functions, programmable pre- and post-alarm recording and sector naming for monitoring of obscured locations, such as the museum entrance area for example. "

Heer GmbH installed normal surveillance cameras in the outer area of the Rothschild Palace, which was built from 1812 to 1824.  A total of eleven eneo CCTV cameras monitor the exterior facades, barriers and entrances.  In addition to the 42" plasma monitor, their pictures are also switched to a further seven eneo control monitors at the cash desk and personnel entrance, and they are recorded by an eneo 16-channel DLR1 Digital Recorder in the control centre.

Designed for discrete video surveillance

Sittig is fully satisfied with the innovative camera system: "The 360° camera with matching recorder is the optimum solution for us.  The system fulfils all the criteria we require: it is easy to install, its virtual cameras have everything in view throughout the whole area and they, just like the Almira Recorder, deliver clear and sharp pictures!″

In this project, the preventative use of the camera system that is seen immediately upon entering the building is rather unusual: the camera and recorder were designed for discrete video surveillance and can be housed nearly invisibly in the ceiling when required.   And, in some cases, are: the tiny cylinder camera that is installed barely noticeably above the entrance steps and which delivers first-class pictures, for example.
