What Is It?

Cothron Security Professionals in Austin, Texas says:  CCTV (closed-circuit television) is a TV system in which signals are not publicly distributed but are monitored, primarily for surveillance and security purposes. CCTV differs from cloud surveillance in the way the signal is transmitted and it is not posted to the cloud nor as accessible.

• CCTV relies on strategic placement of cameras, and observation of the camera's input on monitors somewhere. Because the cameras communicate with monitors and/or video recorders across private coaxial cable runs or wireless communication links, they gain the designation "closed-circuit" to indicate that access to their content is limited by design only to those able to see it.​
• Older CCTV systems used small, low-resolution black and white monitors with no interactive capabilities. Modern CCTV displays can be color, high-resolution displays and can include the ability to zoom in on an image or track something (or someone) among their features. Talk CCTV allows an overseer to speak to people within range of the camera's associated speakers.

CCTV is commonly used for a variety of purposes in Austin and surrounding cities, including:

• Maintaining perimeter security in medium- to high-secure areas and installations including schools, airports, courts, apartment buildings, hospitals, banks and other businesses.
• Observing behavior of incarcerated inmates and potentially dangerous patients in medical facilities.
• Traffic monitoring.
• Overseeing locations that would be hazardous to a human, for example, highly radioactive or toxic industrial environments.
• Building and grounds security.
• Obtaining a visual record of activities in situations where it is necessary to maintain proper security or access controls (for example, in a diamond cutting or sorting operation; in banks, casinos, or airports).

​​CCTV is finding increasing use in law-enforcement, for everything from traffic observation (and automated ticketing) to observation of high-crime areas or neighborhoods.

Here Are The 8 Different Types Of CCTV Cameras:

1. Dome CCTV Camera

Dome CCTV Cameras are most commonly used for indoor security and surveillance applications. Dome cameras get their name from the dome-shaped housing in which they sit. These housings are designed to make the CCTV cameras unobtrusive… not covert or hidden. Typical applications are retail, where the camera is designed to be unobtrusive, but visible.
The "dome" shape makes it difficult to tell the direction that these cameras are facing, and thus are ideal for deterring criminals. The “bad guys” will know the facility is being watched and customers will feel at ease knowing the facility is being protected. Units that allow the camera to pan/tilt/zoom and spin quickly within the housing are often referred to as “speed domes.”
Speed Dome CCTV cameras give the surveillance operator the ability to move the camera. There are cameras that have automated pan/tilt/zoom functionality where the camera is moving on a timed basis. These are used to cover a wide area with only one camera, or to avoid poor light conditions at certain times of day.

2. Bullet CCTV Camera

Bullet CCTV Cameras have a long, cylindrical, and tapered shape, similar to that of a "rifle bullet", often used in applications that require long distance viewing. The camera is not typically designed to have pan/tilt/zoom control but instead to capture images from a fixed location, pointing at a particular area. 

A bullet CCTV camera is a wall-mount or ceiling-mounted unit that is typically designed for indoor use, but can also be used for some outdoor applications.  Many bullet cameras can also be waterproof by being installed inside protective casings, which protect against dust, dirt, rain, hail and other harmful elements.  

3. C-Mount CCTV Camera

C-mount CCTV cameras have detachable lenses to fit different applications. Standard CCTV camera lenses can only cover distances of between 35 and 40ft, therefore, with C-mount CCTV cameras, it is possible to use special lenses, which can cover distances greater than 40ft. 

4. Day/Night CCTV Camera

The day/night CCTV cameras have the distinct advantage of operating in both normal and poorly-lit environments. These cameras do not have Infrared illuminators because they can capture clear video images in varying light conditions and in the dark. 

The camera is ideal for outdoor surveillance applications, where Infrared CCTV cameras cannot function optimally. These CCTV cameras are primarily used in outdoor applications and they can have a wide dynamic range to function in glare, direct sunlight, reflections and strong back light 24/7.

5. Infrared/Night Vision CCTV Camera

These night-vision CCTV cameras have the ability to see images in pitch black conditions using Infrared LEDs and are ideal in outside conditions where lighting is poor to zero.

6. Network/IP CCTV Camera

These cameras, both hardwired and wireless, transmit images over the Internet, often compressing the bandwidth so as not to overwhelm the web. IP cameras are easier to install than analog cameras because they do not require a separate cable run or power boost to send images over a longer distance. 

7. Wireless CCTV Camera

Not all wireless cameras are IP-based. Some wireless cameras can use alternative modes of wireless transmission. But no matter what the transmission method, the primary benefit to these units is still the same: extreme flexibility in installation. 

8. High-Definition HD CCTV Camera

​Ultra high-definition cameras are often relegated to niche markets, such as casinos and banks. These give the operators the ability to zoom in with extreme clarity (to look at a poker player who might have something up their sleeve).
