Modern system of monitoring dorms

Basic system architecture of the IP CCTV system

Maisel SudParis is an non-profit organization whose main mission is to provide accommodation for students of two prestigious French universities: "Telecom SudParis" and "Telecom Ecole de Management" (former INT). The campus located in Evry consists of six buildings with single rooms, studios, apartments, common living areas such as kitchens, dining rooms, laundry rooms, meeting rooms.

In order to counteract vandalism committed on the open access equipment, the administrator decided to install video surveillance system. The system will be launched in February 2010.

It will consist of 106 vandal-proof ACTi cameras integrated by managing and recording software (NVR) - domes with standard resolution (CAM-7321) and megapixel cameras ACM-7411. IP technology allows for simple construction of the large system and provides effective management tools. High resolution of the cameras increases the effectiveness of the fight against pathological behavior. Vandal proof housings of the cameras are ideal for such applications - the cameras can operate without fear of being damaged.
After startup of the system the investor expects a significant reduction of vandalism and petty crime.

Trends in IP video transmission

The main problems in transmission of video data is size of the files and sensitivity of video streams to time delays. Currently and in the foreseeable future, H.264 algorithms ensure the best results - the lowest bandwidth and disc space requirements, the shortest download time. The parameters are about 30% better than in the case of MPEG-4 ASP compression. The newest codec is used by the most technologically advanced companies using mainly Texas Instruments platform (DaVinci).

Market research shows that in 2011 H.264 will catch up with MPEG-4 and then become the undisputed leader.
The tendencies were the subject of ACTi lecture at IFSEC in Birmingham.

DIPOL and Elsa Cheng at Securex fair

Elsa Cheng from ACTi is responsible for market development in Eastern Europe. For the first time she visits Poland, Slovakia, Czech Republic, and Hungary. On April 22 she was the guest of Securex trade fair in Poznan and she also visited our headquarters in Cracow.

New megapixel camera from ACTi

The new product of one of the leading manufacturers of IP cameras - ACTi - marked as ACM-4200 (K1510) belongs to megapixel group. Its 1.3 Mpix (1280 x 1024) resolution means three times more pixels in comparison with standard CCTV cameras. The employed CMOS sensor allows operation from 0.5 lx level without day/ night function. Implementation of MPEG-4 codec allows to transmit and record images of 1.3 Mpix resolution without high bandwidth and disc space requirements. Below we compare this camera with a product of another leading manufacturer.

Wireless IP surveillance system in shipyard

The board of MB'92, one of the well known companies providing services for the most luxurious yachts, mainly those making voyages from the Mediterranean to the Caribbean and vice versa, decided to protect their shipyard facilities by installing video monitoring system.

Because of specific environment, no cabling could be used. The only solution has been application of wireless solutions based on packet transmission. There have been employed ACTi devices - PTZ cameras K1215 and fixed cameras K1118. Both models are Day&Night devices, capable of round-the-clock monitoring. Effective MPEG-4 compression limits disc space requirements for the server to 2.8 GB per day. code:RbN3TUWCf

Monitoring of several locations with remote surveillance center

The main problem that has to be solved in this case is transmission and recording of video data. The solutions used in modern installations divide the video surveillance system into smaller units with individual servers. Management functions can be executed by client station connecting with the servers. Additionally, setting access rights, Internet browser will allow to follow the video online, e.g. when motion detection has been triggered. The solution can be can be implemented with ACTi devices, as in the picture.
