What Is a CCTV Camera? – FPC Forrest City

A CCTV camera is an electronic surveillance device that records all images it captures. These devices can be set up to automatically record at specific times during the day, or record when motion is detected. Unlike old-fashioned analog videotape recorders, CCTV cameras are capable of capturing images at high resolution and frames per second.

The technology allows a camera’s shutter speed to be slowed down to let more light through. This allows the camera to capture a more detailed image. While the technology may not be suitable for all video surveillance applications, it is a desirable feature in many applications.</p> <p>High-definition (HD) cameras are particularly useful in environments where there is a high risk of theft. For example, businesses that have a high risk of theft should consider investing in high-definition cameras. These cameras will enable the police to clearly identify anyone caught on tape in the event of a crime. A smart security consultancy will offer free quotations for CCTV installation and will also carry out site surveys to ensure that the installation of cameras meets the legal requirements.</p> <h2>Analog cameras support 720p and 1080p</h2> <p>There are two major formats for video streams that are available for CCTV cameras: 720p and 1080p. Both use coaxial cables and can support both IP and analog cameras. While 720p is the standard for HD-TVI cameras, it is not supported by all analog CCTV cameras. Both formats support the same coaxial cable length.</p> <p>1080p cameras use twice the amount of pixels than 720p cameras. Higher-resolution cameras also provide larger images and can help identify objects from a distance. While the <strong><a href="https://computerstorebd.com/">CCTV Camera</a></strong> higher resolution cameras are more expensive, their cost is driven down by increased competition. The higher resolution also requires more storage space and better zooming capabilities.</p> <h2>Wide-angle cameras support varifocal lenses</h2> <p>Varifocal lenses allow photographers to capture a wider variety of scenes. They can zoom in and out without distortion and cover areas of the scene that may be hard to see otherwise. Varifocal lenses are often rated between 2.8mm and 3mm, which means that they offer a wider angle of view than a standard lens.</p> <p>With a varifocal lens camera, you can adjust the focal length and zoom level, and choose a focal length that is most appropriate for the environment. In a typical 6mm wide-angle CCTV camera, you will not get much detail beyond twenty to thirty feet. Then, you’ll need a camera with a higher resolution to enlarge the image. Alternatively, a camera with a varifocal lens allows you to bracket a specific area of concern, even if the camera is located at a distance.</p> <h2>Siamese cable is used to transmit video signal to a security camera recorder</h2> <p>There are two main types of cables available for security camera recording. One type is called an Ethernet cable, and the other type is called a Siamese cable. Both types are made of two wires, and their purpose is to send power and video signal to security camera recorders. The thickness of each cable will affect the way it functions, with thinner cables being easier to use. Thicker cables, on the other hand, will provide uninterrupted signal and connectivity.</p> <p>Siamese cable is made up of two 18awg wires – one red wire (positive) and one black wire (negative) – which connect to the power terminals. It is important to maintain the proper polarity in the power connection, since improperly connecting one wire to the other can result in a short, damaging the security camera or starting an electrical fire.</p> <h2>Wireless IP cameras are more flexible than analog cameras</h2> <p>Wireless IP cameras have a number of advantages over their analog counterparts. For example, they do not require a separate power supply and can be placed almost anywhere. Another advantage is that you don’t have to worry about weather or other obstacles when placing them. In addition, they can easily be upgraded to IP by using a PoE switch.</p> <p>Wireless IP cameras are more flexible than analog CCTV camera systems because they do not require a DVR. In contrast, analog CCTV cameras require each camera to be wired directly to the DVR. Instead, IP cameras can be connected to a switch, which connects to a network video recorder. This reduces the amount of cabling required when installing the system and allows for more cameras to be connected seamlessly.</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> </p> <p>
