CCTV Box Microphone ZENITH

One of the most common questions in CCTV systems is the ability to record sound with equipment such as NVR. In short, it is possible to record sound in all surveillance systems and all types of CCTV equipment. Microphones in surveillance systems have many uses in different locations and are usually installed indoors. Of course indoor cameras can also be used with weather-resistant microphones. Microphone CCTVs There are different types of microphones for recording audio in CCTV equipment, and In terms of case type and volume adjustment, the following are divided into two groups: Needle-type Classification Microphones: A small microphone and a hidden microphone category because its structure is such that it can be stored in compartments. Duct also applied. Microphone Box: As its name implies, a rectangular body and screw To adjust the volume on the embedded Ast.mykrvfn Glfy: This type of microphone has a body similar to a golf ball that is very lightweight and compact, and voltage to 12 volts 6 to 0.2. Classification in terms of sound adjustability The other microphones used in CCTVs are based on sound adjustability, which are divided into two volumetric and non-volumetric categories. The sound of these types of microphones is tuned by the winding that is built into them. When installing microphones in closed circuit equipment, it should be noted that it is best not to place the microphone near places with high noise pollution such as windows, as it will reduce the quality of the recorded sound, and with it hissing and other disturbing sounds. Donor should also be recorded. Microphones in a variety of CCTV Microphones and sound recordings in CCTVs are available in a variety of ways that can be performed in any of the CCTV systems, including analog, HD analog and IP network cameras. Receives: Installing the Microphone on the Analog CCTV These systems connect the microphone directly to the DVR recorder, which means that an analog signal is transmitted between the microphone and the DVR. The limit on the number of microphones that can be connected to a DVR depends on the number of audio inputs embedded on the DVR. Microphone mounting on a CCTV Voice recorder on a CCTV is performed directly by the NVR recorder. But the microphones are not connected to the NVR, either directly to the camera or inherent to the original design of the cameras. The limit on the number of NVR-compatible microphones depends on the number of audio inputs embedded on the NVR. IP cameras with microphones are mainly suitable for indoor use. Microphone mounts to HD analog cameras In HD analog cameras, the microphone connects directly to the HD-DVR device. But recently, cameras of this type have been introduced that come with a built-in microphone. CCTV microphones often allow audio and video use together. Usually the power of the microphones is answered by the camera adapter which you need to connect from the camera to the microphone. Microphones are part of the CCTV controller. It is best to keep the microphone away from sound and magnetic devices for sound and sound. All points are easy to install and easy to use
