DIPOL Weekly Review - TV and SAT TV, CCTV, WLAN

No. 22/2011 (May 30, 2011)

Big Brother is watching you in the crowd.

A panoramic camera with a resolution of more than 125 times greater than that used in conventional CCTV systems and a system capable of identifying people in the crowd received the prizes for the best products at the International Fire and Security Exhibition and Conference (IFSEC) 2011 in Birmingham.
The Panomera multi-sensor system offered by Dallmeier company has been designed for comprehensive video monitoring of large facilities such as stadiums. The recorded material can consist of up to 51 megapixels, the recording speed can reach 30 fps!. The movement of selected individuals can be automatically tracked, thanks to intelligent analysis of the video. All the time the system ensures permanent recording of the entire panoramic scene, allowing further analysis of other details.
The second winner was the software presented by iOmniscient, regarded as the only solution existing in the market capable of identifying faces in a crowd. The system can recognize people wearing headgear and glasses, located at different angles relative to the axes of the camera lenses.
iOmniscient is an Australian based company known for years for its innovative ideas in the field of security systems. Its detection and identification products are used in the most demanding environments with a high degree of risk, such as airports, railway stations, shopping malls.

The awards at the renowned trade fair show the rank of the products and their importance for the industry. This year's awards set a new trend in the video security market.
Manufacturers, in response to market demand, prepared advanced solutions for automated surveillance of large gatherings of people. Video surveillance, so far associated with the protection of places/objects, is entering the field of counter-terrorism security and identification of people.
Currently, the development of CCTV is based on intelligent analysis of the video. The award-winning solutions enable not only to recognize an individual, but also to find the person in the crowd in a very large facility (e.g. a stadium).
Intelligent systems can detect threats and analyze the video many times faster than the operator(s), and also have a certain level of artificial intelligence allowing for certain automated preventive measures.

The possibility of identifying people in a crowded street, gathered at a concert or football match etc. will enhance security, but also may become a tool for surveillance on an unprecedented scale.

Antennas in an absolute monarchy.

This is one of the richest countries in South-East Asia. The basis of its revenue is export of crude oil and natural gas - it accounts for about 90% of the gross domestic product; in 2008 the GDP per capita was $50100 - for comparison the GDP of the U.S. was $49900 at that time.
However, as seen in the photographs, there is a problem with redistributing the income.
In the following pictures the elevation angles of the satellite dishes amount to 90 degrees. So, it means that the dishes are located close to the equator, but where? The answer at the end of this issue.

SMATV system with 60 outlets in an apartment building, based on TERRA MSV equipment.

One of the building developers in Katowice, Poland, wanted to provide the future residents with the possibility of receiving television from multiple sources: CATV, terrestrial TV (DVB-T), and satellite TV. For this purpose, there have been created two parallel distribution systems, CATV and SMATV.
The design office responsible for the project chose advanced solution based on TERRA MSV multiswitches. The whole installation was to ensure the distribution of DVB-T and satellite signals to 60 outlets. All active components of the SMATV system were grouped in a one, central location.
The IPLAN installation company did not have any problems with implementing the system thanks to previous designing of the network with the use of the TERRA SatNet software which calculates the optimum settings of the amplifier and multiswitches.

The system is composed of the following elements:
  • amplifier for 9-input multiswitches: Terra SA-901 R70901 - it amplifies TV SAT and terrestrial TV signals and ensures power supplying for the system
  • SAT/TV splitter Terra SS-504 R70515 to create two subnetworks
  • two multiswitches Terra MSV-932 R70882 to distribute satellite signals from two satellites (Hotbird+Astra) and terrestrial TV signals to 64 outlets ( R694100 )
In addition, the system provides the location for the MT41 TERRA R871741 modulator. The modulator allows for conversion of a baseband video signal (e.g. from analog CCTV camera) into RF signal that is distributed in the system and can be received by each of the residents.
Noteworthy is the fact that the installer has employed Signal R48602 TV-Sat surge protectors at the inputs of the equipment and E80340 compression F connectors from PCT company, ensuring trouble-free operation of the system for many years.

Event-triggered high quality recording.

It happens that the footage recorded after motion detection, including the pre-alarm period, is not suitable for the identification of people, due to insufficient image quality.
The solution to this problem is to temporarily enhance the recording resolution. Such a function has been implemented in Hikvision-Ultimax DVRs of 7300 series ( M74040, M74080, M74160 ) and 8100 series ( M76080, M76160, M78080, M78160 ).
This unique solution is both simple and effective. For each channel, the user is able to define two parameters of the video: for continuous recording and recording after an event. These parameters can be set independently. After defining the responses to events (motion detection, video tampering etc.), the DVR will automatically switch to the recording mode with higher parameters. In the remaining time (in the continuous mode) the DVR saves disk space by using lower parameters. This way the surveillance footage from an incident (also just before it) contains maximum detail, whereas the recordings between events may have a much lower performance (resolution, bitrate), saving the storage space.
Hikvision DVRs are known not only for high performance and technical parameters, but also for high reliability. The described solution uses one of many advanced features embedded in the latest lines of the products from a world's leading manufacturer.

Central power distribution in large CCTV systems.

The main advantages of central power distribution in CCTV systems are easier installation of the equipment and better system integrity and security.
A large number of devices in the system requires a power supply with adequate current capacity. A power supply with high output current (10 A) is the DRA-120 M1835. The advantage of this supplier is the ability to work in parallel with second or even third identical unit - then the current consumption can be as high as 30 A. Such a capacity is sufficient to power, for example, 16 CCTV cameras mounted in housings with heaters, a DVR and several IR illuminators. The adjustable output voltage (from -10% to +15%) allows for compensation of voltage drops.

CCTV in a disco.

To improve safety in a disco, the owner decided to install a high definition IP CCTV system. Aside from high resolution, he wanted reliable equipment capable of operation with IR illumination. Another requirement was compliance with PoE standard to minimize the number of cables. Of course, the solution also had to be cost-effective, due to a very limited budget.
The camera which has fulfilled these expectations is Pixord PD614E K1550, with resolution of 2 megapixels. Due to a mechanical IR filter, it can cooperate with ceiling-mounted IR illuminator Redbeam M1642 that evenly illuminates the whole room (radiation angle of 180/360o).

The camera does not need to cooperate with a server, because it can record the video data on a SDHC card (up to 32 GB) inserted to the built-in slot. With such a memory, the PD614E K1550 camera can record video footage from up to three days, which can be viewed locally or remotely via IE of Firefox.

GSM repeater in a wind power plant.

A wind power plant operator in Hruszowice, Poland, had a problem with low and unstable GSM signal which had to be used to transmit the data needed to monitor the performance of the system.
The data from sensors deployed in the wind towers should be transmitted to an automated control room and then to the turbine factory located in Germany.
The problem has been overcome by installing GSM repeater. The DIPVISION installation company used:
  • GSM repeater Signal GSM-505 A6775,
  • directional outdoor antenna ATK 10/850-960 MHz, A7018,
  • indoor antenna TRANS-DATA DW3-A A741001,
  • RF surge protector TRANS-DATA A6815,
  • Tri-Lan 400 E1173 and Tri-Lan 240 E1171 cables.
Signal repeaters meet all European requirements for such kind of equipment. They have already been successfully installed in Austria, Czech Republic, Finland, Great Britain, Holland, Norway, Poland.
