Cisco like a big tanker. At ISC West (International Security Conference - April 2-4, 2008) in Las Vegas, Cisco Systems, Inc. presented new IP video surveillance products.
The role of Cisco in IP-based technology is so important that it is worth to focus on the products and scenarios.
There was shown 4500 IP camera of 2 megapixel resolution (1920 x 1980), utilizing H.264 compression. For standard applications Cisco prepared 2500 IP camera, both as wired and wireless version (the latter supporting 802.11b/g/n standards). The "n" option makes it probably the first CCTV camera that supports the newest wireless standard (draft 2.0). The cameras can cooperate with Cisco Stream Manager 5.0, offered for about 300 US dollars per one channel.
The next, new field of activity of Cisco is IP-based physical access control. The company presented both hardware and software components utilizing IP network for integrated security operations.
Door readers, locks and biometric devices, and the Cisco Access Gateway - together with the software component - Cisco Physical Access Manager, make a complete and scalable platform that can cooperate with existing systems and other software applications (e.g. databases).
Cisco, like a big tanker, can only sail on the deep, along the main routes.
The solutions developed by this IP leader, based on H.264 compression and "n" standard, will be the lodestar for other, smaller companies.
The new direction of Cisco towards physical access control may be a strong impulse for quick development of this market segment.

Tower of Liberty. TV transmission towers are strategic buildings, very well protected. They allow to transmit TV and radio programs which can shape public opinion - a very important element of acquiring and maintaining political power.
The tower in the picture is especially important for the city and country which it is in. In January 1991, several months after the country declared independence, 14 citizens died there while trying to maintain the blockade against troops equipped with tanks. There were over 600 people injured.
Where is the tower? The answer at the end of this issue.

Distribution of satellite signals in small and medium apartment blocks - MSR-524 multiswitches. The R70624 multiswitches with 24 outputs provide perfect solutions for medium sized buildings. The multiswitches are equipped with graded output levels (in three groups). It allows to equalize signal levels in wall plates located in different distances from the multiswitches. High isolation between outputs minimizes interferences between the receiving devices. For installations with above 24 outlets there are needed additional multiswitches, e.g. R70604, R70608, R70612, R70616. Signals from Quatro LNB and terrestrial TV should be previously split/tapped through TERRA splitters or taps - SS-504 R70515 (for similar/symmetrical branches), or SS-510 R70516, SS-515 R70517, SS-210 R70518 (for unsymmetrical branches). The multiswitches allow to power antenna preamplifiers with 12VDC.

ULTIMAX - digital video recorders for demanding customers - full range of choices. DIPOL has launched on the European market a whole family of 3rd generation network DVRs of ULTIMAX series. There are three groups of them, depending on the computing power of processors and some other features. The most powerful subfamily is 700 series, then go 500 and 300 models. The 700 series contains 16-ch and 8-ch DVRs, the 500 and 300 series also include 4-ch models. The flagship DVR of 700 series - M77160 - is capable of recording 4CIF (D1) images at 25 fps, simultaneously from all 16 channels.
The main common features of ULTIMAX family distinguishing it in the market:
- 24 months warranty,
- the newest and most efficient H.264 video compression,
- recording and live viewing in 4CIF/2CIF/CIF/QCIF resolutions - see the table below,

Comparison of typical PTZ cameras and megapixel cameras. Most cameras used in CCTV systems in stadiums are PTZ devices. It is due to the fact that one such camera can cover a large area and thanks to optical zoom - to narrow the field of view to the most interesting at the moment fragment in order to identify important details.
Despite these advantages, there are also significant limitations. In the case of two operators there is a risk of conflicts during PTZ control. In zoom mode the field of view covers only a small area - the rest is out of control at this moment.
These limitations are overcome by using megapixel cameras (very high-resolution cameras). Use of such cameras e.g. in stadiums allows to record a complete coverage of any event - the interesting details the operator/s can enlarge not only at the moment of live viewing, but also from the recorded video. No incident or detail will be overlooked. Below - digitally zoomed images from standard and megapixel camera.

How to configure the TP-Link TL-WR542G router? Router connects two or more logical subnets, e.g. external network with Internet access (WAN) with local network (LAN), making a bridge for information exchange. Without proper configuration the connection will be impossible. In most cases, router acts as a specialized computer (replacing a standard computer) working in external network, with software and hardware tailored to the tasks of routing and forwarding. It allows to create internal (local) network.
In this case, configuration of the computer includes:
- taking down all settings of the NIC (working in external network),
- IP address
- Subnet mask
- Default gateway
- Preferred DNS server
- changing the way of address assignment to dynamic (DHCP), or setting fixed IP address from the router's range,
- connecting the computer with LAN port of the router.

Vilnius. The Vilnius TV Tower is a 326.5 meter-high (1071 ft) building, the highest one in Lithuania. The tower was completed in 1980. Its structure is composed of a concrete base, a 190 m long hollow reinforced concrete pipe, and a 136 m long steel spike. At 160m there is an observation deck and coffee shop - in a concrete saucer. In 1991, 14 unarmed civilians lost their lives opposing the Soviet troops that wanted to seize control of the tower.
One of the most interesting buildings in Vilnius is St Ann church, built in the style of flaming Gothic
