How Do CCTV Cameras Work?

CCTV stands for closed circuit television. Instead of being publicly broadcasted, signals from security cameras are sent to private monitors for surveillance. If you are considering installing CCTV systems for commercial buildings or home security, it helps to know how they work.

Continue reading to learn how CCTV cameras prevent theft while keeping you safe. For help finding the best security cameras, give the fire protection contractors at Fire Pros a call.

Camera Placement

You’ll need to strategically place surveillance cameras around your home or commercial building. For example, it’s standard to have security cameras trained on the entrances and exits. If you live in an upscale neighborhood, you may decide to install home security cameras for your front and back yards. A home surveillance system can reduce the likelihood of a break-in so you and your family have peace of mind.

Many of our customers decide to install visible and hidden cameras for maximum security. Visible cameras deter shoplifting by letting people know they’re being watched. Hidden cameras, on the other hand, are great for capturing footage of people who try to hide their faces from the cameras.

Hidden cameras can also catch employee theft and let you know which of your workers are honest. In the retail industry, loss from employee theft is referred to as inventory shrinkage. While you may not like to think about your own employees stealing from you, it’s also important to protect your livelihood with a security system.

Monitors

closed circuit TV has 4 parts: CCTV camera, lens, monitor, cables. Signals from your CCTV cameras are sent to monitors via wireless communication links or private coaxial cable runs, which makes them “closed circuit.” In other words, other people won’t be able to access your video surveillance footage.

Unlike the grainy black and white monitors of the past, modern security camera systems are in high-resolution color. The footage is recorded on video tape or DVR. Some CCTV systems even allow you to zoom in and track movement. For example, security personnel can use the CCTV system to track a suspicious person walking around your commercial building after hours. The type of lens your camera has will determine whether it can zoom in and out.

Who Uses CCTV Cameras?

CCTV cameras can be used for both residential and commercial properties. Many businesses (like banks and airports) need security cameras so they have a visual record of activities. CCTV systems can handle two or more cameras, which is great if you need to keep a large area secure.

While outdoor security cameras often deter burglars, they are still useful after a break-in. When you file a report with the police, you’ll be able to give them the security footage the day of the break-in so they can identify suspects. A home camera system can also capture suspicious behavior, like someone casing your house several days in advance. The sooner you report suspicious behavior to the police, the safer you and your family will be.

Fire Pros is a security system company that offers commercial and home security systems to customers in six states. We cover all of Michigan. To learn more about our security and alarm systems, call 800-968-2871.

Wet: Remove and replace the outdated water gauge. Pressure surges are typically trapped in the system by the check valve. Readings from these gauges can be used to establish a database on the available pressure in the water supply. The gauge on the supply side is also used during the main drain test to establish a database of residual pressure in the water supply. NFPA 13 (8.17.3) & NFPA 25 (13.2.7.2) Gauges shall be replaced every 5 years. Wet: Install (2) missing spare sprinkler heads in the spare head box. NFPA 25 (5.4.1.5) A supply of at least (6) spare sprinkler shall be maintained on the premises so that any sprinklers that have operated or been damaged in any way can be promptly replaced. Wet: Perform 5-year Hydro-Static test on the Fire Department Connection (FDC). Also perform the 5-year internal inspection of the FDC. NFPA 25 (13.7.4) The piping from the fire department connection to the fire department connection check valve shall be hydro-statically tested at 150psi (10 ba
