But not the number of exhibitors is decisive for the importance of CES, but their marketing potential. The conferences are attended by prominent persons - usually the presidents of world giants. This year the strongest impression was made by Bill Gates. The owner of Microsoft informed about agreement with NBC on cooperation in providing coverage of Beijing 2008 Olympic Games. He also presented his concepts of development of computer technology - the most interesting ones include use of 3D techniques, and "natural interfaces" between the computer and the man (voice, touch).
As usual, the highlight of the show was presentation of the largest television screen. Two years ago it was 103 inches, last year - 108 inches, and this year... plasma panel of Panasonic had 150-inch screen (381 cm)! The company did not say how much the mega-panel will cost - probably such television with 8.84 million pixel image resolution won't be cheaper than $100,000 (USD).
Similar sensation was induced by 11-inch High Definition OLED television Sony XEL-1. The first HDTV set with OLED (Organic Light-Emitting Diode) screen makes a next breakthrough in display technology - it ensures low power consumption, high contrast and peak brightness, excellent color reproduction - pure and vivid colors in both dark and bright images.
All this comes with a "hair's breadth" of the screen - the thickness of XEL-1 screen is about 3 mm! So far, there are problems with production of larger screens, and the innovation has its price - in the case of this model it is about $2500.
Like every year, the cnet.com website announced the list of products of the categories represented at CES, nominated to "Best of CES awards". The list shows the newest technological trends and also expresses consumers' views on the market.
Here are the category winners.

As an example: - According to the developer's requirements, each apartment has been equipped with one satellite cable. But after a year, many or the residents have bought twin PVR receivers and want to get next signal. The solution is simple - on the floors where we need more cables we change the multiswitches for more capacious ones - the rest of the installation does not require any change and the whole system functions normally.
The new series of 9-input Terra MSR-9XX multiswitches is dedicated both for home installations, as well as for multi-story buildings - as story devices. An important feature of these multiswitches is diversification of signal levels at different outputs, which enables the installer to compensate the losses in cables of different lengths that are unavoidable in such systems.
Additionally, the multiswitches have been equipped with correction of cable's characteristics, i.e. the signal level is increased adequately to the growth of cable's attenuation for higher frequencies.

There are two possibilities of selecting the appropriate mount/arm. In the case of a universal mount the manufacturer gives the range of screen size of the panels that the mount is suitable for. When assuming a specific screw pattern, the producer informs about it, specifying e.g. VESA MIS-D 100, 100 x 100 mm etc.
| VESA | Screen size | Max load | Screw pattern | |
| inch | cm | kg | mm | |
| MIS-B | 4 – 8 | 10 – 20 | 2.0 | 20 x 50 |
| MIS-C | 8 – 12 | 20 – 30 | 4.5 | 35 x 75 |
MIS-D 75 MIS-D 100 | 12 – 23 | 30 – 58 | 14 | 75 x 75 100 x 100 |
| MIS-E | 23 – 31 | 58 – 78 | 24 | 100 x 200 |
| MIS-F | over 31 | over 78 | 114 | 280 X 150 200 × 200 600 X 200 400 × 400 600 × 400 800 x 400 |
These days the increasingly popular method of camera adjustment involves OSD (On-Screen Display). It eliminates the need of implementing an array of microswitches and potentiometers that we can sometimes see in more advanced models.
An advanced OSD system has been implemented, for example, in the SN-586C/B M11208 camera with DSP sensor, made by Pixim. All picture parameters are adjustable with the use of buttons situated on the rear panel of the camera case.
The manufacturer has enabled the user to save camera settings in the memory, to preset the camera before on-the-spot calibration.
The user has full control over all parameters, from video norm, through AWB, ES, BLC, Gamma, ...., to specific settings connected with WDS (Wide Dynamic Sensor).
The camera has a lot of advanced options that are not accessible in other models:
- D/N Control - setting the threshold of Color to B/W switching and vice versa,
- privacy zones - possibility of concealing some parts of the image (with black area),
- motion detection - additional information on the screen after the image has changed,
- mirror - mirror image,
- title - camera name.
We have tested quality of transmission between wireless camera Pixord P400W K1132 put into the best-fitting housing - Marathon TS-816 M5407, and access point (AP) located about 20 meters from the camera. The first problem is arrangement of the camera antennas - they cannot be set vertically, but only horizontally or in an intermediate position - we have tested various arrangements. The tests have shown that the metal housing decreases by half signal level. So, is the game worth the candle?
Yes, when there is no possibility of laying cables, either by land or by air (e.g. on poles). This solution is easy to implement and cheap.
However, we have to remember about using access point with a high-gain antenna (depending on the distance), to compensate the loss of signal caused by the camera housing.
Remote client software enables simultaneous unlimited access to the archives and live images from up to 64 cameras.
Netstation allows to use PTZ cameras (e.g. K1214, K1215). It has been equipped with all popular protocols, as well as with possibility of adding next positions or editing new ones. The cameras can be controlled by keyboard, mouse, or USB joystick - K9153.
Netstation software packages for systems with 4 - 64 channels.

The details have been described in the article What is DDNS and how to use it?.
Application in the local network more than one IP device requires to employ a router. TP-Link ADSL (Annex A) router TD-8840 with integrated 4-port switch (N2905) fulfills all the requirements.
The diagram shown below illustrates the concept of home LAN which enables the residents to operate their computers and distribute via Internet both live and recorded video data (from the DVR).

The software is installed in the same way as firmware update. It is available here.
