Homeowners would like to increase their comfort level while conserving energy. An excellent method to do this is through zoning. Most two-story homes have an 8 to 10 degree temperature difference between upstairs and downstairs (because heat rises). Additionally, larger ranch homes generally have a big temperature difference between one end of the house and the other (due to the distance of the duct runs).
This article describes how MP3 music from a computer in the home office was distributed throughout the house on existing cat3 phone wires for a customer not willing to spend a lot of money with professional installers. It took less than half a Sunday afternoon to finish the whole project. Even though this project utilized cat3 wires, the solution is applicable to cat5, cat5e and cat6 wiring as well.
One of the most recent and promising wireless personal area network (WPAN) technologies is the IEEE 802.15.4/Zigbee standard. The harmonious combination of the IEEE 802.15.4 standard and the Zigbee wireless technology holds the promise to satisfy the market?s need for a cost-effective, standard-based and flexible wireless network technology for control and monitoring applications with low to moderate data rates.
The IEEE1394 serial bus is a low cost and high performance bus that interconnects consumer electronics audio video devices and PCs. The 1394 bus enables simple interconnections between devices with a single cable wire. The devices can be plugged in and out of the 1394 network while they are in powered on stage, i.e., hot pluggable. The devices get automatically detected and configured without any necessity for manual configuration. The devices can talk to each other, i.e., peer-to-peer communication, without any intervention or support of Personal Computers. The 1394a standard bus supports 100,200,400 mbps speeds and 4.5 meter cabling. Whereas the latest 1394b standard supports speeds 100,200,400,800 up to 3.2Gbs and Plastic optical cabling (POF) up to 100 meters.
Consumers are demanding ? and advances in semiconductor technology have enabled -- bigger and better color screens, more intuitive user interfaces, faster performance, more wireless interconnectivity, and smaller and more portable form factors. This means that for the same battery size and battery lifespan, all types of electronic products must take advantage of low power semiconductor devices in order to incorporate more features while consuming less power.
Taking the protective reflective screen off a rear projection television increases black levels, reduces glare, and makes for a much-improved picture, especially during daylight hours.
The innovative R & D team at Wisdom Audio has finally succeeded in capturing the signature sound of the highly acclaimed Adrenaline Series in an in-wall speaker.
Most people do not realize that a TV is merely a 2-dimensional picture. It?s a well designed 5.1 ? 7.1 channel audio system that actually provides the needed ?3-D? effect.
These ideas will allow the installer to provide for the installation of an unlimited numbers of doorjamb controlled lighting arrangements.
For installers who have not setup and configured PTZ cameras, it is always a good idea to set the camera up at your shop first using short wire runs. Ensuring you can setup and configure the camera properly will greatly reduce your installation time.
Most residential modulators have output ranges on the CATV band from Channels 65-135. Since the output of the modulator and the digital cable signals are on the same frequency, they cannot be combined onto the same coaxial cable without interfering with each other.
HAI and Lightolier is a product combination that is reliable, fast, flexible and 2-way, a tough combination to beat for an integrated whole house scene-based lighting solution.
With the emergence of high definition television formats, and the plasma and LCD progressive displays that take advantage of them, the need for high quality de-interlacing is self-evident.
