CCTV Camera Types & Their Uses

What many people don’t know is that there are a variety of different types of CCTV camera which suit different situations or premises, and that selecting the proper camera for the right application really is vital. Different Types of CCTV. Here, we run through these types of camera and what makes them unique and more suitable for some venues over others. The shape of the camera makes it difficult for onlookers to tell which way the camera is facing, which is a strong piece of design, deterring criminals by creating an air of uncertainty. C-mount cameras, where standard CCTV lenses can only cover distances of 35-40ft, can cover distances beyond 40ft thanks to the possibility to use special lenses with these cameras. 

PTZ – Pan/tilt/zoom – cameras allow the camera to be moved left or right, up and down and even allow the lens to be zoomed closer or farther. It’s extremely important to ensure that you have chosen the right CCTV camera, because depending on where they’re positioned and their primary use, you will need to find one that best accommodates your needs. Whether you’re looking to install a CCTV camera outside a property to catch criminal activity, or have placed one inside to monitor the home or a company’s goods, there’s something for everyone. Choosing the right lens will allow your camera to focus and will bring enough light to the sensor on the camera, helping you to read registration plates and recognise faces etc. The highest resolution you can get is 700TVL but many mainstream cameras range between 300-550TVL.

The Skyscraper Center

The CCTV headquarters is an unusual take on the skyscraper typology. Instead of competing in the race for ultimate height and style through a traditional two-dimensional tower soaring skyward, CCTV’s loop poses a truly three-dimensional experience, culminating in a 75-meter cantilever. CCTV’s form facilitates the combination of the entire process of TV-making in a loop of interconnected activities. Two towers rise from a common production studio platform, the Plinth. Each tower has a different character: Tower 1 serves as editing area and offices, and the lower Tower 2 is dedicated to news broadcasting. 

The main lobby, in Tower 1, is an atrium stretching three floors underground, and three floors up. The CCTV headquarters also facilitates an unprecedented degree of public access to the production of China’s media: a Public Loop takes visitors on a dedicated path through the building, revealing everyday studio work as well as the history of CCTV, and culminating at the edge of the cantilever, with spectacular views towards the CBD, the Forbidden City, and the rest of Beijing. A Media Park forms a landscape of public entertainment, outdoor filming areas and production studios as an extension of the central green axis of the CBD. The innovative structure of the CCTV Headquarters is the result of long-term collaboration between European and Chinese architects and engineers to achieve new possibilities for the high-rise. A versatile, efficient structure that bridges in bending and torsion between the Towers to create the continuous form of the Overhang section, the diagrid provides enough strength and stiffness in the Towers to carry loads to the ground. 

The structural system stiffens the podium and tower bases to favorably distribute loads to the foundation. This allows large studio spaces to be laid out within the towers. It has enabled the Overhang section to be constructed without the need for temporary propping, since the braced skin provided stability as the steelwork was cantilevered out from the towers.
