Recesia, pokles, kríza? - CeBIT 2009. "Objav svet ICT príležitostí" (ICT - Information and Communication Technology) je hlavný slogan tohtoročnej výstavy CeBIT, ktorá sa bude konať v Nemeckom Hanoveri od 3. do 8. Marca. Hlavnými témami výstavy budú "Webciety" (Web Society - webové komunity) a zelené IT.

Medzi vedúce témy tohto obchodného veľtrhu bude patriť Webciety (Web Society) a Green IT.
Webciety sa zdá byť číslom jedna - kostra tohto projektu bude podporovať riešenie a spoločnosti, ktoré sa vzťahujú k Enterprise 2.0, Open Source, blogovaniu, stránkam typu wiki, on-line konferenciám a on-line bankovníctvu.

Enterprise 2.0 predstavuje zmenu v prístupe ku koncepcii Internetového obchodovania - zmyslom je zvýšiť postavenie stávajúcich zákazníkov a umožniť im podieľať sa na vytváraní a obiehaní informácií. Príkladom známeho nástroja Enterprise 2.0 sú blogy.

Druhá hlavná myšlienka veľtrhu CeBIT, Green IT, je európskou odozvou na vývoj trhu informačnej technológie a telekomunikácie v Ázii a Spojených štátoch (musíte si poradiť so všetkými okolnosťami, povedal šéf, zaväzujúci si svoje topánky pomocou dážďoviek).

V januári bolo spoločnosti Motorola Inc. vyjadrené uznanie formou jedného zo svetovo najdôležitejších priemyslových ocenení za dizajn - cena iF za produktový dizajn. Víťazom sa stal APX 7000 prenosný viacpásmový obojsmerný rádioprijímač spoločnosti Motorola. Cena iF za dizajn bola predstavená v roku 1953 a udeľuje sa jeden krát ročne nemeckým iF Medzinárodným fórom pre dizajn. Tohtoročná iF porota zhodnotila ako vždy približne 3000 výrobkov predložených z 39 krajín. Ocenené výrobky sú predstavene na veľtrhu CeBIT 2009 v pavilónu iF.

V predošlom roku sa na veľtrh CeBIT dostavilo cez 5900 vystavovateľov, ich výrobky a ponuky si pozrelo 400000 návštevníkov.

Recesia, depresia, kríza? - podľa propagačného oddelenia tohto veľtrhu je pomocou proti týmto zlomom účasť na udalostiach ako CeBIT 2009.

Takže... vyskúšajte pohostenie v Hannoveri.

Krajina masívnych anténnych stožiarov. V Španielsku majú vysoké konštrukcie stožiarov, v Holandsku - oceľové tubusové stožiare - často umiestňované priamo na podklad a dostatočne pevné, aby odolali silným vetrom fúkajúcim od mora.
Krajina, v ktorej sa nachádza nižšie zachytený stožiar, neleží v Európe. Kam sa máme vydať, aby sme spozorovali takéto stožiare? Pokiaľ Vás nič nenapadá, pozrite sa na koniec tohto vydania.

V akej krajine môžete vidieť takéto konštrukcie?

Inštalácia konektorov na kábel TRISET-11. Inštalátori pracujúci pravidelne v rámci MATV/káblových televíznych systémov sú si plne vedomí problémov spojených s prípravou F konektorov pre vysoko kvalitný koaxiálny RF kábel. Kvôli silnému opleteniu je zložité vložiť vnútorný drôt do niektorých typov týchto konektorov. Aplikácie nových F konektorov (E80360) americké spoločnosti PCT tieto problémy eliminujú a zaisťujú jednoduchú inštaláciu.

Príprava začína odstránením plášťa z káblu pomocou nástroja E80035. Potom sa nasadí na kábel a je stlačený pomocou univerzálneho kompresného náradia PCT-AIO-CT (E80075). Celá táto práca trvá menej než 20 sekúnd. Nakoľko klasický domový systém vyžaduje desiatky konektorov, môže táto moderná kompresná technológia ušetriť hodiny tvrdej (a zbytočnej) práce.


K dispozícii sú nasledujúce PCT konektory:


Insulation Stripper HT-322S (for RG 8, 11, 213, H1000)
Compression F Connector: PCT DRS-11QP (for TRISET-11)

Different versions of popular CPD560 DVR. Customers often choose equipment according to the name of a model/group of devices and do not pay enough attention to significant differences among versions in the group. Comparing prices from various suppliers they tend to choose the less expensive device, and therefore the least equipped or with outdated accessories.
An example of this situation is the CPD560 (AVC760) DVR M85039, offered by many companies in various versions. The differences include kind of video compression, type of hard drive supported, and optional SATA adapter:
  • CPD560 - MJPEG, ATA,
  • CPD560 - MJPEG, ATA + SATA adapter,
  • CPD560 - MPEG-4, ATA,
  • CPD560 - MPEG-4, ATA + SATA adapter,
  • CPD560 - MPEG-4, SATA.
The cheapest version uses MJPEG compression and is prepared for ATA hard drive. MJPEG compressed video requires two times more disc space than the same material recorded in MPEG-4 (at the same quality level). It is a significant limitation of the available storage potential. MPEG-4 compression also requires lower bandwidth of the network, or, using the same transmission speed, ensures better quality of the transmitted video.
Use of SATA HDDs is more economical than application of "vanishing" and more expensive ATA drives.
DIPOL offers the most advanced version of CPD560 DVR - MPEG-4/SATA M85039.

ULTISYSTEM - a unique and honored surveillance software - cooperation with alarm inputs and relay outputs. ULTISYSTEM software allows to utilize I/O modules of IP devices. Most IP CCTV devices have such modules with alarm inputs and relay outputs.
ULTISYSTEM enables the operator in the monitoring center to see the statuses of the inputs and control the outputs. It is very important function in the case of "intelligent" buildings. The management over the inputs/outputs is maintained through the status/control panel (see below) that is always active during monitoring a camera.

For example, ULTISYSTEM can manage:
  • alarm system
  • fire prevention system,
  • access control system,
  • power and control systems (lighting, gate drivers, door entry, etc.)
More on this subject in the next issue.

Transmission of CCTV data across IP network. The main advantage of IP CCTV systems is use of IP protocols enabling packet transmission. This kind of transmission allows to combine many signals (data streams) that can be transmitted via one cable or other transmission medium (on the condition of adequate bandwidth). It gives a great superiority over analog systems based on DVRs that require a separate cable for each channel. However, it is possible to integrate both systems. The coupling device is transcoder, decoding MPEG-4 stream from an IP device and converting it (in real time) to high-quality analog video. In ACTi systems this function is performed by ACTi ACD-3100 K2413. The device also enables bidirectional audio transmission in the network and hardware motion detection. It can decode PTZ commands (RS485), as well as supports alarm functions (I/O signals). The transcoder is compatible with all ACTi devices working at PAL/NTSC resolutions, for example fixed camera (K1117), high-speed ptz camera K1215, video server K2113.
Video servers and transcoders allow to build hybrid CCTV systems utilizing analog equipment and providing the functionality of IP networks.

DMZ function in TP-LINK TL-WR542G N2950 (example device). DMZ function (exposed host) allows full bi-directional communication between one client computer and the Internet, for specific purposes like Internet games (requiring connections with predefined ports), video conferences etc.
As a rule, routers block all non-standard ports, denying access to such online services. DMZ host redirects all ports allowing full communication. The computer with redirected ports has to have permanent IP address and is not allowed to use DHCP client function (it could change this IP address).
TP-LINK TL-WR542G 54Mbps is a wireless router that comprises router, firewall, and access point. The main applications include small and medium-size businesses, one-family houses and apartments. TP-LINK TL-WR542G provides a quick and convenient way of building wired and wireless network based on one external broadband service. The network, consisting of a number of computers, is additionally protected by firewall.

To configure DMZ host in TL-WR542G N2950, enter the Forwarding >> DMZ tab and:
  • mark Enable option,
  • fill in the DMZ Host IP Address field (IP of the computer in LAN),
  • clik Save to save the setiings.

Jordan. The earlier roots of Jordan as an independent state can be traced back to The Kingdom of Petra, which was founded by The Nabataeans, an ancient Arabic Semitic people. Petra enjoyed prosperity, wealth and independence hundreds of years until it was occupied by the emerging Roman empire. Beside the Nabataeans, Jordan witnessed many other smaller ancient kingdoms including the Kingdom of Edom, the Kingdom of Ammon and the Kingdom of Moab, all of which are mentioned in the Bible. During the Greco-Roman influence a number of semi-independent city-states also appeared in Jordan under the umbrella of the Decapolis. Later, Jordan became part of the Arabic Islamic Empire across its different Caliphates stages including Rashidun Empire, Umayyad Empire and Abbasid Empire. After the decline of the Abbasid, Jordan was ruled by several conflicting powers including the Mongols, the Crusades (a few dozen years sice 1099, as the part of The Kingdom of Jerusalem), the Ayyubid and the Mamluk until it became part of the Ottoman Empire (1517 -1918).

The significance of connectors in CCTV systems. Every connector, even the best one, causes degradation of the signal. The basic rule is minimizing the number of connections in the transmission channel. Usually manufacturers of connectors give two important parameters describing loss of signal. The first, Voltage Standing Wave Ratio (VSWR), informs about which part of the signal is reflected back to the source of the signal...
