What Are The Different Types of CCTV Cameras?

March 9, 2020|fsstechnologies

Your company’s security camera is part of a closed-circuit television system (CCTV). CCTV uses one or more cameras, through either wireless or wired transmission, to send the broadcast from the camera directly to a monitor, set of monitors, or a recording device—providing you peace of mind in the case of crime, fire, theft, or accidents in the workplace.

While most use CCTV systems for surveillance as part of their security system, other uses include safety monitoring or video streaming to larger audiences for a limited-space event, such as an additional viewing room outside of a crowded courtroom during a trial. Learn more about what the different CCTV camera options are for your business.

What are some common CCTV camera styles?

We’ve explained the two primary kinds of security cameras and their resolutions, but let’s go a little deeper. There are several different styles of cameras under the analog and IP camera umbrellas. Their names may not be super creative; however, they tend to indicate the location of the installation or even the appearance.

Here are some of the most common types of CCTV cameras your business can use:

  • Dome cameras are named for their rounded shape and are popular because they are visible yet blend well with their surroundings. Their design makes it difficult for people to know exactly where the lens is looking. Some multi-camera CCTV systems use decoy domes, keeping people guessing as to whether or not there’s an active camera in use at any given position or moment. It’s a good idea to change up which cameras are and are not in use if you employ this tactic in your security system.
  • Bullet cameras, also known as lipstick cameras, tend to be mounted outdoors and focused on a specific area. Bullet cameras mainly differ from dome cameras because they generally have a more extended range, making them ideal for viewing larger areas like parking lots. Most bullet cameras need a protective case and have a small lip to protect against glare and weather.
  • Fisheye or panoramic cameras usually come in 180- or 360-degree models to cover a wide angle. They can even provide legally admissible facial recognition footage up to 15 feet from the mounted position.
  • Pan-tilt-zoom (PTZ) cameras move left to right (pan), up and down (tilt), and have an optical zoom to get a close look at distant areas. Users can control positioning remotely via a keyboard, joystick, mouse, or even a phone app. Some PTZ security cameras feature presets and automatically scan between predetermined locations.
  • Turret cameras are a version of dome cameras. The turret is a ball-and-socket joint, similar to your hip, that swivels to allow for easy adjustment of the camera’s position after installation.

Night-vision security footage

Do CCTV cameras have night vision?

Some kinds of security cameras work at night, which is a cost-effective solution for around-the-clock surveillance in comparison to installing a separate infrared system for monitoring after dark. Cameras switch to night mode when light levels dip below a certain point. Expect a 10- to 15-percent drop in resolution compared to daylight, but rest assured, that level of performance is more than sufficient for most scenarios.

However, more is not always better when it comes to night vision. Be sure to select a camera with a range of no more than double the expected viewing distance. For example, if your desired viewing distance is 40 to 50 feet away, choose a camera with a 100-foot night vision range. The sweet spot is 50 to 80 percent of the camera’s max night distance. Going over this range can create hot spots that look bright white on your monitor.

How do you store CCTV recordings?

The two primary devices that support security video storage are a Digital Video Recorder (DVR) and a Network Video Recorder (NVR). The difference between the two is how they process the video captured by the camera. DVR systems handle the footage at the recorder, meaning everything is stored in one device.

In contrast, NVR systems encode and process the video at the camera and stream it to the NVR recorder for storage and remote viewing. Most DVRs are used with analog cameras and are part of a wire-based system, whereas NVRs work with IP cameras and can be part of a wired or wireless network.
