CCTV Cameras or closed circuit television cameras are types of cameras which have been used for security purposes for a very long time now. The main difference between these cameras and conventional cameras is the fact that these cameras transmit the signal to certain viewers only, which means that the video or images from these cameras cannot be publicly seen. These cameras have been used for preventing and solving crimes for a very long time, and they are most commonly related to security cameras in stores, malls, gas stations and so on, but people are also starting to use them for home security. The fact is that there are many different types of CCTV cameras, and here some of them will be explained CCTV Camera Price in Bangladesh.
Types of CCTV Cameras According to Size and Shape
The most popular of these types of camera shape is the dome camera, which is often used not only because of its practical shape, but also because it is easy to disguise. Aside from this, dome cameras are usually smaller than other types of CCTV cameras, which is a great feature for discretion, as well. On the other hand, the box shaped CCTV cameras are probably the most commonly used type in public buildings and everywhere where there is no need for the camera to be hidden. Quite the contrary, it is a fact that people are less likely to commit crimes if they are aware that a camera is monitoring them.
Types of CCTV Cameras According to Functionality
There are two different types of these cameras, according to whether they are to be used during the day or during the night. During the day, regular CCTV cameras are used, which are able to monitor long distances and provide their users with high quality videos and images. On the other hand, if the CCTV camera has to be able to film during the night, it has to be an infra-red or night vision camera. Even though these cameras cannot monitor long distances, they are still used to monitor happenings near the camera. They use heat or night vision technology to create a clear image even in total darkness.
Types of CCTV Cameras According to Transmission of Signal
Logically, CCTV cameras can either be wireless or they can send the data through a fixed cable connection. Generally speaking, modern types of these cameras all use a wireless connection, and this connection can even reach as far as 500 feet. On the other hand, a fixed wired connection has a great flaw in the fact that it has to be physically connected to the receiver of the videos and images. Wireless cameras can run through their batteries very quickly when filming or transmitting, so they need to be recharged regularly.
When faced with a decision of which type of camera to choose, it is best that you do some research and find out which type is best for your circumstances. Also, it is always a good idea to shop around and visit as many stores and websites as you can until you find one that will provide you with a high quality product with the features you need at competitive prices.
