Founded in 1993 by Maurice Thal and George Phillips, the company has been supplying security related security equipment to the southern African market for more than 20 Years. soft touch backlit keys allow for easy programming of the system. basic home automation can be achieved with the aid of digital actuators to switch lights, air conditioning, control blinds, curtains and roller shutters. Established since 1967 Farfisa Has been manufacturing intercom systems for more than 40 years. Product experts are available covering the whole of Raicom’s product range. any current on these lines will interfere with the quality of the intercom system. the prefered is AC as the lock will buzz when the voltage is applied. the buzzing sound notifies the visitor that the gate is being opened. 2A) CISA Electric locks are strong and robust, designed for outdoor applications. Since the same plug is used for video and DC auto iris lenses, will the camera determine which type of lens is connected? It tells you a ratio between the maximum and minimum iris opening. The focal length determines what you will see on the monitor. This is called Field of View and is expressed in degrees. The light dependant varying voltage will open and close the iris. Vari-focal lenses have the ability to change focal length similar to a zoom lens, However there ia a major differences between the Most vari-focals are compact in size and do not have the ability to track (maintain focus while changing focal length. A Video Auto Iris lens has a little amplifier built in which responds to the amount of ambient light and will open or close the iris automatically to maintain the same amount of light coming into the CCD imager. Zoom lenses have the ability to change focal lengths much like a vari-focal. However, they differ in many ways from a vari-focal. A zoom lens typically offers a wider range of focal lengths and is physically larger than vari-focal. They can be purchased in Manual, 3-motor type, and Auto-Iris versions. They also have the ability to track (maintain focus while changing focal lengths) and can be operated remotely. Some motorized zoom lenses also offer a Pre-Set ability for the zoom, focus, and iris functions. Using a so-called filter shifter, the IR Cut Filter can be swivelled in, which means that in day mode the IR Cut Filter is moved in front of the sensor in order to block out the interfering infrared light. In night mode the IR Cut Filter is moved away so that IR light may pass through. The iris is the mechanism which allows more or less light into the lens by the opening and closing of the iris leaves. The balun is connected between the coax cable and the twisted pair to match the impedance of the transmission lines. The 4-pin plug, in most cases, is a small rectangular connector that plugs into the back or side of the camera.
