$1,000,000 for "the Internet of things"!

At the October conference Demo Fall 2012, the People's Choice Award winner and owner of $1,000,000 for promotion in IDG Media became Ube, an American startup company, for developing a new concept of a smart home.
The award-winning company presented a universal application capable of remote control of home appliances, including "ordinary" devices that are powered from AC line voltage. In the first phase of the project they plan to integrate 200 products from various manufacturers, by providing remote control via TCP/IP protocols. The users of smartphones will be able to control not only TVs, STBs and other modern electronic devices, but also thermostats, shutters, garage doors and lighting - all the components of the connected homes that will be really "smart".
In addition to software, Ube has also developed three IP devices. Their task is to control all the electrically powered devices or installations that do not have network interface and which should be included in home automation systems, such as lighting. Their biggest advantage is the simplicity of implementation due to direct connection to the existing wiring in the home or office. Other solutions offered so far for building automation have usually been expensive and not very intuitive.
Ube at Demo Fall showed that the rise in popularity of smartphones and the potential of Android and iOS provide new possibilities for applications in this area, making them much cheaper, versatile and most importantly - extremely easy and intuitive for users, by a significant reduction of human involvement in common processes which can be based on the "Internet of Things" - interconnected machines with specific functions. Just imagine, when you are approaching your home, your smartphone will turn on the coffee maker to brew a fresh cup of coffee, switch on the TV on the channel with your favorite series, adjust the temperature in the room depending on the atmospheric conditions...
From the left to the right:
  • Smart Plug can be plugged into any wall outlet to control a wide range of appliances from a smartphone and measure the consumed energy
  • Smart Dimmer based on a 32-bit ARM processor and Android OS changes light intensity and the energy consumption according to the needs of the user
  • Smart Outlet used to replace an existing outlet - identical functions as the Smart Plug - for higher loads
In the past, home automation devices were expensive, unintuitive and difficult to use. The advent of Apple and Google platforms on mobile devices allows for the dissemination of this kind of technology due to wide accessibility and ease of use.

Fiber cable management.

Splice enclosures or panels provide locations to store all splices/connections safely and efficiently. Any installer of fiber optic cabling has to have the necessary skills to connect/terminate/arrange the cabling in network nodes, interconnection and end points. One of the ways to terminate optical fibers is to connect them with pigtails, adapters and patch cords.

The picture above shows an example of the fiber cable management in L5506 box. Single-mode fibers have been connected with PG-53S L3553 pigtails via Ultimode Fast-MS1 L5550 mechanical splices. Each pigtail is connected to A-533S L4233 adapter mounted on the front panel of the Ultimode MT-548 L5148 box.
One L5506 splice tray (two such trays come with the L5148 box) can accommodate up to 16 L5550 splices, the total number of the splice trays can amount to four. The installer should pay special attention to the maintenance of the appropriate bending radius of each fiber and the order of the fibers and trays required for optimum accessibility.

DVB-T television and the Internet via one UTP cable.

Low-voltage systems in office buildings often do not include TV antenna cables, but are usually fitted with structural cabling based on UTP cables. When some users want to connect televisions to watch DVB-T broadcasts, the lack of an RF distribution system may be a major obstacle (in many locations TV signals cannot be properly received using indoor antennas).
A unique solution to this problem is to use SIGNAL TV-LAN baluns for TV over UTP, R94200. The pair of the passive baluns can transmit analog/digital RF signals from an antenna placed in a suitable place via the existing UTP cable. The transmission is performed in parallel to the "normal" use of the cable for data transmission (LAN, Internet). The idea of using the Signal TV-LAN baluns is presented in the figure below.
Baluns for TV over UTP: Signal TV-LAN (2 pcs)
Transmission of DVB-T and Ethernet signals over a single UTP cable with the use of R94200 baluns
Although the solution is based on point-to-point connection, it is possible to use multiple transmitter-receiver kits, even in combination with TV splitters and network switches. When the RF signal level after splitting is sufficient for further distribution, the signal can be sent over another UTP cable segment after a network switch, using additional pair of the baluns.

Solutions based on the baluns are much more economical in comparison with deployment of additional systems based on coaxial cables or IPTV technology (the latter also requires extra network resources). They do not convert the original RF signals, only change the transmission medium.

How to choose a UPS?

Uninterrupted power supplies (UPSs) provide emergency power to the supplied devices in the case of power line failures. The basic criteria for this type of equipment include the maximum active and apparent power, and battery run-times for specified loads.
The total active and apparent power consumed by all devices connected to a UPS cannot exceed the parameters declared by the its manufacturer. When the values of apparent power of some devices are not declared by their manufacturers, a safe assumption is that they are twice as large as the wattages. In the case of non-linear loads (e.g. computers), at least 20% power margin should be included.
The battery run-time depends on the batteries used (quantity, capacity and voltage). The table below shows run-times depending on the actual load. For example, a desktop computer with monitor (total load of 125 W) will be backed by the CyberPower OR1000 N9705 UPS for more than 35 minutes.

How to use alarm connectors in Sunell cameras?

Sunell IP cameras K1620, K1630, K1660, K1665, K1670, K1690, K1691, K1695 have alarm inputs/outputs that can be used for additional protection of the monitored facilities. All configuration procedures are contained in the menus of the cameras.
The pinout of alarm connectors in Sunell IP cameras
The alarm input is activated by applying DC voltage (+5...12 V, "high" state) at the pin marked IN, with respect to the ground (COM). There is also the option to activate the input by "low" state (when the +5...12 VDC voltage is disconnected from the IN pin).

The alarm input of a camera can cooperate with various sensors:
  • PIR sensor - intrusion detection is performed by detecting differences in infrared radiation (increased temperature) occurring between an intruder/object and the environment
  • glass break sensor - reacts to the sound of breaking glass
  • door/window sensor - the alarm signal is generated after opening door/window
  • smoke or gas sensor (hydrogen, carbon dioxide, methane, butane etc.) - reacts to reduced transparency of the air or an increased amount of the chemicals in the air
The use of the alarm output
Activation of the alarm input can trigger the alarm relay output of the camera (close/open the pair of the relay contacts). Such a switch can control any actuator (e.g. a siren) powered from an external 12 VDC source, with current consumption up to 300 mA.

How to install rack-mount devices on a wall?

Devices in enclosures compliant with rack standard can also be installed outside rack stands or cabinets. In the case of limited space available, there may be no room even for a low-size hanging cabinet.
Antenna UHF Preamplifier AA-101 ALCAD
Wall mount RACK frame SIGNAL 19" 4U R912009
Such problems can be solved by the use of R912008 (2U) or R912009 (4U) frames intended for mounting devices compliant with 19" RACK standard directly on walls. It is a good solution when a small number of installed devices does not enforce to use a cabinet, especially in places where it is not necessary to protect the devices from unauthorized access. The hinges on one of the sides of the frames ensure easy access to the mounted devices from the rear without disassembling.

How to reduce the costs of expanding a passive optical network (PON)? Increasingly more popular passive optical networks make it possible to connect up to 64 or even 128 users to one transmitting device. Their network architecture is based on unpowered optical splitters which introduce significant attenuation in the transmission paths (splitting ratio of 1:4 is equivalent to attenuation of about 7 dB). It means that extension of a passive network involves the exchange of active devices, either for transmitters with a higher output power or for receivers with increased sensitivity... more
