DIPOL Weekly Review - TV and SAT TV, CCTV, WLAN
No. 22/2014 (June 2, 2014)
ANGA COM 2014 - a small impasse, or a significant crisis? On May 20-22, 2014, Cologne in Germany held the latest edition of the largest telecommunications fair in Europe, ANGA COM. According to official information, the 22 thousand square meters housed the stalls of 450 exhibitors from 34 countries. Within three days the exhibition was visited by about 17000 people from 70 countries, which is an increase of 1.5% compared to last year.
Until now ANGA has been an exception among similar trade fairs, each year gathering increased numbers of exhibitors and, even more important, of the crowds of visitors. The May or June events seemed to disclaim the popular opinion that in the Internet era such trade fairs are becoming obsolete. This latest figures were not as good as before, but it was still an increase. But what about the content?
The vast majority of the 17000 visitors could get the impression that the fair, which has so far been showing market trends in the television industry, for the first time in its history offered no really new ideas or products.
Many exhibitors presented already firmly established and popular technologies such as HbbTV, OTT, or Second Screen, but these solutions were present at previous editions of the fair. An exception is 4K TV, which seems to be blooming now, having the chance to become a universally accepted new standard. Once again, everyone could notice the triumph of IPTV and its derivatives. The conversion of any existing standard of digital broadcasting, i.e. DVB-S/S2 , DVB-C/C2 and DVB-T/T2 to IP protocol allows for adding a range of interactive services. But due to the costs of implementation, this solution becomes popular only in some Western European countries. The more traditional method of distributing multiple TV channels was represented by the first devices compliant with the latest DOCSIS standard (3.1). DOCSIS 3.1, published in October 2013, has been designed for cable networks and offers significantly higher data rates with the use of ultra-fast 4096QAM modulation - download up to 10 Gbps, upload up to Gbps.
Is the impasse that reached the ANGA fair only a momentary shortness of breath? We have to wait for the answer till June 9, 2015, looking forward to the next edition of the fair.
The latest fair was dominated by UHDTV technology. There were both 4K televisions and a range of broadcasting equipment necessary for shooting and processing content in this resolution. Beside the growing popularity of SAT> IP conversion, one could notice the first CATV> IP implementations (Schweiger stand) confirming the trend of converting various signals to IP stream.
One of the greatest attractions of the fair was the TV using "Dual View" technology, showcased by Vestel. The television displays two different images at the same time. Wearing the appropriate pair of glasses, the user can watch one of the channels. Unfortunately, the manufacturer did not explain the way of sound distribution. If the issue is resolved, the dilemmas of the "match or the series" kind will not exist any more.
Now is the time for fiber optics. An installation company working in the field of SAT/TV and CCTV systems received a proposal for the installation of telecommunication systems in a newly constructed commercial complex. A substantial part of the telecommunications infrastructure of this modern facility was to be based on fiber optics. The installers had to be equipped with new tools.
Set of tools for connecting optical fibers - ZN-001
The components of the L5953 tool set
The ZN-001 L5953 kit is an ideal set of tools and devices for installers beginning work with fiber optic systems. The components are needed to prepare optical fibers for splicing, both by fusion and mechanical means. Thanks to high quality and precision, the purchase of the tools will pay off for many years to come.
The main components of the set are: fiber stripper SP-001 for flat cables - L5906, 3-hole fiber optic stripper for typical 900/250/125 µm single-mode and multimode fibers, high precision fiber cleaver ODW-001 L5802, ferrule end-face cleaner NC-001 L5916, visual fault locator (10 mW, for 2.5 mm ferrules, 635-650 nm).
Full HD images on multiple televisions in a shopping mall. DVB-T encoder and modulator Signal-751 R86751 can distribute high definition digital video signal to multiple televisions via RF coaxial cables. It is an ideal solution in shopping malls, electronics stores etc. The distribution network is identical with a shared antenna system (typical coaxial cables and RF splitters), much cheaper than in the case of an HDMI solution. There is no problem with connecting next televisions to the network, the system is very reliable due to only one active component (the modulator) and simple cabling and connectors.

Another advantage of the Signal-751 modulator is the ability to provide parallel UDP/IP stream (IP multicast technology) that can be distributed e.g. by WiFi network.
Signal distribution system in an electronics store. Thanks to the application of the Signal-751 R86751 DVB-T modulator, promotional HD video is easily provided to fifty or so televisions. The system has been deployed by NCK Grupa.
The source HD signal is provided via HDMI input. The HDMI interface supports HDCP, is compatible with every BluRay or DVD player, as well as with CATV STBs and satellite receivers.
Video surveillance of a ground parking lot. The key to effective monitoring of parking lots is the proper selection of cameras and lighting. For effective monitoring of poorly lit parking lots one requires cameras with increased sensitivity, supported by IR illuminators. An example of high quality camera ideal for this purpose is Sunell IRC59/21AKDN M11289. A big advantage of the camera is a mechanical IR cut filter (ICR), the application of which ensures accurate color reproduction in visible light. It eliminates possible problems with identification of colors of the cars on video recordings. Additionally, the Sunell IRC59/21AKDN M11289 model is equipped with a powerful IR illuminator with range up to 50 meters.

Optimal set of cameras for monitoring a parking lot
The parts of parking lots with sufficient lighting can be monitored by u-cam 650 M11194 cameras equipped with Jensen M2136 lenses. This model of CCTV camera is characterized by high resolution and sensitivity, as well as excellent image processing performed by Effio processor. The use of HLC function (High Light Compensation) ensures that the images from the camera will not be overexposed by the headlights of passing cars.
Additionally, the whole parking lot can be monitored by high speed dome camera PH-33 M1196 equipped with 33x super-zoom lens.
Next model of ULTIPOWER PoE switches. DIPOL introduces another switch from the PoE family - ULTIPOWER 0288af N29983. This desktop device ensures smooth connectivity in 10/100/1000 Mbps Ethernet networks. Aside from its eight RJ45 10/100 Mbps PoE ports, it has one RJ45 1000 Mbps port for connecting to access network and two SFP 1000 Mbps ports allowing for integration with optical networks. The latter feature is rather exceptional in the case of switches with only 8 PoE ports and can be very useful in extensive CCTV networks. All the PoE ports automatically detect PD devices compliant with IEEE 802.3af standard and provide them with power supply. It allows the user to expand the network coverage in areas where there is no access to AC power lines/outlets and to employ access points, IP cameras, IP phones, etc.

New options in the firmware of Sunell cameras. The latest update (1.8.1001) of the firmware of Sunell IP cameras includes the options of direct playback of surveillance data stored on SD card (in the browser window) and of selecting the resolution of the secondary stream. So far, the sub-stream was defined as 640x480 pixels. Now, the choice is among:
  • 640x480 pix
  • 640x360 pix
  • 352x288 pix (CIF)
  • 320x240 pix (QVGA)
  • 144x176 pix (QCIF)
The greater range of options allows the user to better tailor the image parameters to the capacity of the network.
The monitoring window in CCTV Mobile app in Fluent mode
(320x240 pix - the priority is the smoothness of movement)
The new resolutions support the previously inaccessible Balanced and Fluent modes in CCTV Mobile application for Ultimax K2104, K2108, K2116 IP NVRs. The firmware update can be performed with the use of FTP Update app. The new software is dedicated for all Sunell IP cameras supporting Flash technology.
