The NVT NV-213A converts the video signal coming from a single CCTV device so that it can be transmitted over UTP (unshielded twisted pair) telephone wires. Along with color and B/W video, this unit will also transmit coaxitron (up the coax) PTZ control signals over the same UTP wire, eliminating the need to run a separate control cable. Transceivers negate the need to have both a listening and transmitting radio. There are savings in both space and money. Portable walkie talkies in particular are frequently used by staff at events and in, for example, casinos. The transmitting and receiving sections share certain components like circuitry, antennas, power source and controls.

    About Transceiver:

    • Hand-held radio transceivers operate on narrow band frequencies.Radio waves are the part of the electromagnetic spectrum with the longest wavelengths. A transceiver is a type of radio equipment that can both transmit and receive this long wavelength radiation to communicate with other people or share to data. Transceivers are more common than you might think. Amateur radio hobbyists and CB enthusiasts talk to one another using transceivers. A walkie-talkie is a radio transceiver and so is your cell phone. Even the wireless router connected to many computers is a type of radio transceiver

    Frequency Coverage

    • The Federal Communications Commission regulates the frequencies that different types of communications equipment may transmit and receive. Transceivers of different types are built so that they transmit and receive signals at the range of frequencies allocated for that type of equipment. Frequency ranges are allocated for mobile phone, 2-way radio, citizens band and amateur radio transceivers. According to the National Association for Amateur Radio, amateur radio transceivers operate at set wavelengths from 23 centimeters up to 160 meters. Frequency availability is determined by the class of license the operator holds

    Transmitter Power

    • The transmitter inside each type of transceiver is designed to operate at a set power level. The output power is measured in watts. A walkie-talkie type hand held transceiver will have a power out put of around 5 watts. This means that the transmitter inside sends a signal at 5 watts of power through the antenna. Base transceiver units and CB radio transceivers operate at higher power levels. The instruction manual for a VHF/HF transceiver provided to students by the University of Indiana describes the transmitter power of the base unit to be between 5 and 100 watts when transmitting an FM signal and between 5 and 40 watts for AM signal transmission

    Software Defined Radio Transceivers

    • ICs and software process the signal in SDR radio transceivers.Software Defined Radio transceivers bring amateur radio into the digital domain by combining radio with computers. A SDR transceiver converts the analog radio signal to a digital signal and uses software to process and filter the signal for transmission. SDR transceiver software is configurable to allow the transceiver to operate in the narrow band unlicensed frequencies or in the licensed amateur radio bands. According to the EURASIP Journal on Wireless Communications and Networking, the transceiver sends the input signal through the processor where it is filtered and optimized by the software. The signal is then passed through a converter circuit that changes it from an analog signal to a digital signal. It is then broadcast through the antenna. The type of signal that is broadcast is determined by wireless transmission standards issued by the FCC

Product FAQs
  • Are all transceivers compatible ?
  • Yes. All transceivers made since 1992 work on 457MHz. Previously the USA and Canada were different but now have standardized with Europe (Since 1992).

  • Can i use a digital transceiver with an analogue one ?
  • Yes. all transceivers are compatible. See difference between analogue and digital transceivers.

  • What is the difference between analogue and digital transceivers ?
  • The difference is in the way the transceiver interprets the signal it receives. When you are buried it makes no difference which transceiver you have. All transceivers transmit the same, at different rates but on the same frequency. Digital transceivers process the signal they receive and tell the user in which direction to head, analogue transceivers display the raw signal received and leave it up to the user to decide which way to head. For most people the digital ones are much quicker to use in search mode, but have a smaller range than analogue units.
