It involves digitizing the signal from the image sensor and improving the brightness and contrast. It also helps to minimize color shift due to light sources. Moreover, it also improves compression ratio to make the image clearer.</p> <h2>Function of a CCTV camera</h2> <p>A CCTV camera is a device that records everything it sees. It can be programmed to only record during certain times, or to record whenever movement is detected. It can also be connected to the internet so that you can view recorded videos remotely. A CCTV camera can be equipped with a digital video recorder (DVR), a modern version of an analog videotape recorder. This <strong><a href="https://computerstorebd.com/">CCTV Camera</a></strong> device records video in digital format at any resolution and frame rate.</p> <h2>Types of CCTV cameras</h2> <p>There are several types of CCTV cameras available, each with their own distinct benefits and uses. These include infrared cameras that can record in complete darkness, night vision cameras that record in colour during daytime, and IP cameras that are linked via a network. IP cameras can be accessed anywhere in the world and can offer 24-hour surveillance.</p> <h2>Wide-angle and varifocal cameras</h2> <p>Varifocal and wide-angle CCTV cameras are a great choice for a wide-range surveillance system. These cameras offer flexibility, enabling you to view large areas from the full angle, or zoom in to capture small details. The focal length of a camera is directly related to its range and angle of view, so a longer lens is better if you need to view faraway details.</p> <h2>PTZ cameras</h2> <p>When choosing a PTZ camera, you should consider two factors: the video output options and the amount of optical zoom. The most common video outputs are SDI, HDMI, IP streaming, and NDI. These connections allow you to send video directly to your computer without using any networking equipment. Moreover, they can handle long distances and save installation time.</p> <h2>NVR systems</h2> <p>An NVR system is a great way to keep track of footage from your CCTV cameras. The best NVR systems have more than just recording capabilities. They also allow for audio recording and enhanced tracking features such as face recognition and license plate recognition. An NVR system is also much more expensive than a DVR system.</p> <p>Computer Store BD | CCTV Camera, Fire Extinguisher, Access Control<br /> Ta-129, Moddho, মহাখালী গুলশান সড়ক, Dhaka 1212<br /> 01973-314333</p> <p>
