Over 100 companies returned to the fair after last year's absence, including AMD, Sony Ericsson, Motorola, Siemens. Over 300 other companies came for the first time - among them Google and Amazon. So the statistics seems to be rather optimistic, the decline in the number of exhibitors this year amounted to only 3%, while in the last year was as high as 25%.
Unfortunately, appearances can be deceptive.
Four large exhibition halls were closed, many stands did not have commercial character - the exhibitors took part in the event only because of subsidies. Plenty of space was occupied by exhibitions highlighting artistic achievements (International Forum Design). Crisis in European production had been evident in recent years, this year's fair confirmed another trend - for many producers Europe is no longer a priority market.
Due to bureaucratic barriers to the adoption of standards, many technologies still cannot be used on our continent. This applies, for example, to mobile TV, there are considerable delays in HD television, but also in fiber optic technology.
For this reason, Samsung - the leader in new technologies which presented a lot of new products at CES in Las Vegas - did not have its stand at CeBIT. Many other large companies were represented only by their German or European subsidiaries.
Does the crisis end?
-Some think yes,
are skeptical about it.
In the next issue
we will present a report
on technical innovations
at CeBIT 2010.
Quo vadis Europe?
Where are they building the new highest TV tower? The answer at the end of this issue.
The owner of one of Krakow's jazz clubs required an installation for distribution of two video signals (from analog camera monitoring the scene and from multimedia player) to a network with three television receivers. An additional condition was the ability to easily switch between the two sources of signal, without a need of using individual remote controls of the televisions.
Other typical application is the choice between terrestrial and cable TV. The switch allows to connect the two sources of signal without a risk of interference (it happens that DVB-T transmitters and cable TV networks use the same channels).
Ferguson Ariva HD player 110 A99391 can be the center of every modern home theater. The media player allows to play full HD movies, MKV H.264 files, HD recordings from cameras, high resolution digital images - to watch them on the screen of a connected HD TV set. In addition, it enables the user to play digital music files in the highest quality, also in Free Lossless Audio Codec format (.flac). With support for various data communication protocols, the device allows to play files downloaded from the Internet and home computer network, from USB and NAS hard drives, USB and flash drives (MS/MMC/SD/SDHC), digital video cameras, as well as from external DVD drives.
Main features of the ULTIMODE family:
- cooperation with dedicated type of optical fiber (single-mode or multimode),
- transmission type (duplex or simplex),
- transmission speed (10/100 Mb/s or 1 Gb/s),
- wavelength (I - 850 nm, II - 1310 nm, III - 1550 nm),
- maximum transmission distance (0.55; 2; 20; 40 km).
M - media converter
40 - maximum transmission distance (in kilometers)
3 - wavelength/transmission type (3 - 1310 nm, 5 - 1550 nm, 7 - WDM transmission)
M - transmission speed (M- 10/100 Mb/s, G - 10/100/1000 Mb/s)
V - video converter
20 - maximum transmission distance (in kilometers)
4 - number of video inputs
DAO - transmission of additional signals (D - data, A - audio, O - alarm)
- RJ-45 8-pin modular plug J2008 - for termination of twisted-pair cables in computer networks,
- NETSET UTP cat 5e E1408 - highest-quality twisted pair cable designed for professional data transmission systems inside buildings (structural wiring, LANs).,
- Crimping tool HT-210N J9210 (for RJ45 connectors),
- Cable tester (RJ45, RJ-11) N7055 - testing cable continuity, detecting shorts circuits and incorrect connections. The device can be used for UTP/FTP cables terminated with RJ-45 connectors or for telephone cables terminated with RJ-11 phone plugs.
In practice the number varies from 5 to15 (for 1.5 km link). This depends on the type of radio transmitting equipment, as well as on the type of cameras, that is, their resolution and compression used.
For example, the necessary bandwidth for IP camera with MJPEG compression may be as high as 6 Mb/s, but with MPEG-4 compression will be approximately 2 Mb/s. The bandwidth demand of a megapixel camera can reach up to 15 Mb/s, while a simple VGA camera with VHS image quality will need only 1 Mb/s. So it is impossible to unambiguously determine the bandwidth requirements - they depend on each particular case.
To avoid possible problems with the equipment, it is recommended to use thoroughly tested devices. There are well functioning monitoring systems based on such equipment, e.g. video surveillance system in Myslenice, Poland, with IP speed dome cameras ACTi K1215 perfectly cooperating with ULTIAIR access points, or the megapixel video surveillance system in Tvrdosin, Slovakia, based on ULTICAM cameras and ULTIAIR access points.
In conclusion - wireless solutions are certainly cheaper than wired ones, and the installation is much faster. However, it is important to realize the limitations and problems that can be encountered in the design, configuration and operation stages.
megapixel video surveillance system in Tvrdosin, Slovakia
ULTIAIR devices are characterized by short delays and high throughput. They operate in unlicensed 5GHz band - no special permissions are needed. ULTIAIR devices can operate as base or client stations, they employ reliable Mikrotik system.
This 16-channel DVR allows to record video with resolution of 4CIF at the speed of 2 fps. The number of frames and the resolution can be set separately for each camera. The highest resolution is only used to record images from the entrance to the premises, which enables identification of car license plates and faces of people. The images from other cameras record images of 2CIF resolution (704 x 288) at 12 fps.
At the gate and the gateway there are mounted V-CAM 412 M10744 cameras in vandal proof housings. The images from the cameras are recorded only in the case of motion detection in their fields of view.
Simple graphical menu of the DVR allows to quickly configure the recording schedule (continuous/event triggered).
In the future, alarm inputs and outputs of the DVR are to be connected to control systems of heating, air conditioning and other facilities, providing elements of a "smart home".
The owner is satisfied with the implemented system.
- ACTi ACM-1231 K1511 - fixed cameras mounted on fences, for recording illegal entering of the parking lot. Using megapixel cameras with wide angle lenses the designer can significantly reduce the number of the cameras;
- ACTi CAM-6630 K1216 - speed dome camera/s situated in the central part of the parking lot, allowing the operator to focus on any event taking place on the whole lot;
- NUUO software - for recording and image analysis. With the ability to count objects and alert about the disappearance of an object it is the best surveillance management software for IP CCTV systems;
- ULTIAIR 419KC N2300 + ULTIAIR 319KC N2310 - devices for wireless data transmission.
The designers took care of adequate protection of the tower from earthquakes and probably did it properly - during the recent earthquake which took place in February this year, with a magnitude of 7 on the Richter scale, the only failure was bursting of a water pipe.
