Caller-TVTM from NetMedia is an easy-to-install device that connects your telephone line to your TV and displays caller-ID information on the TV screen when an incoming call is received. It uses an RCA video input and output to display information over a satellite, cable, VCR, DVD or other video signal connected to your TV. The ID information can be displayed as text on top of your existing video feed, as a picture-in-picture (PIP) display, or it will even work without a video source and display a simple blue screen with caller-ID information. The display will last for 10-15 seconds and ID information can be retained until the next call is received. Caller-TV is designed with your convenience in mind, once installed there are no buttons to push or remote controls to deal with. In an instant you will be able to see who is calling, allowing you to make a decision on what to do with an incoming call. Important Note: Caller-ID service or Caller Display service must be activated by your telephone company. Call your local telephone company to make sure you have this service activated to your home prior to installing Caller-TV.
The Net Media SCM1 CAModulator Indoor/Outdoor Weather-resistant B/W Camera with Built-in Modulator provides one of the most innovative solutions available in residential camera applications by appearing to be an ordinary floodlight. This unique system combines a digital-video RF modulator with a CCD-sensor camera, and provides a one-coax installation where the power and video output for the camera share one coax cable. Unlike many ball cameras, the SCM1 is fully adjustable with a 360-degree horizontal and 180-degree vertical positioning range for the housing, as well as 360-degree range for the camera itself inside the housing. Easy to install, this camera comes in a weather-resistant heavy-duty aluminum housing with a glass lens cap that protects it from the elements while still providing unobtrusive security and surveillance.
The Net Media SCM1 utilizes a black-and-white CCD (charge-coupled device) image sensor and a 3.6-millimeter fixed lens. This unit achieves a resolution of 350 horizontal TVL (TV lines), and can receive a picture down to a minimum illumination of 0.7 Lux. This camera features video and power wires that are fed through the housing arm and connect behind the base, keeping them out of sight and away from the elements. The output of the SCM1 is a television channel that can be distributed via a cable distribution system to all of the televisions in the home, meaning no monitor is required. For its output the Net Media SCM1 uses an F-connector, and operates via an RG59, or RG6 or better connection cable. This unit runs on 12-volts DC power supplied via its included cable, and uses a digital crystal PLL (phase-locked loop) modulation method.
Technical Features:
- Sensitivity: minimum illumination of 0.7 Lux
- Resolution: 350 TVL
- Modulation method: digital crystal PLL
- Lens type: 3.6 millimeter fixed
- Dimensions: 5.5 and 4.5 inches in diameter (camera and base)
About Surveillance Camera Technical Features
Lux rating is the measurement used to indicate how sensitive a camera is to light, and stands for the level of light reflected off a piece of paper by a candle from one meter away. Thus a sensitivity of three Lux would mean a camera could generate an acceptable picture of a piece-of-paper-sized object that was illuminated by the equivalent of three candles from one meter away. The lower the Lux level, the better the camera's ability to work in low-light conditions. The camera's resolution should be greater than or equal to the resolution supported by the system's recorder or monitor. The S/N, or signal to noise ratio, is an important measure of a camera's quality. A poor camera, low-light conditions or poor wiring causes "noise" which consumes processing power and disk space. A camera with a wide dynamic range is ideal, especially for recording areas in which both indoor and outdoor light are present. CCD (charge-coupled device) sensors provide high-quality images that are less susceptible to noise. CMOS (complimentary metal-oxide semiconductor) sensors offer less image quality, but are usually more cost-effective and energy efficient.
