Aug 11, 2021 | Security Cameras

Are you considering the addition of a CCTV security system to your business security? Do you need surveillance for a parking area, business, or another type of building?

With a basic understanding of CCTV systems, you’ll be able to make the right decision for your business. Here is an introductory guide to CCTV systems to help you know exactly what this type of security system can do for your business.

What is CCTV?

For most, CCTV is known as the standard type of surveillance security system. It stands for Closed-Circuit Television and transmits footage with a single channel making it a closed circuit. This means any footage from a CCTV system is displayed on a limited number of monitors and won’t be publicly broadcasted.

How CCTV Security Systems Work

By capturing video footage, CCTV systems send the footage to a DVR or NVR to record the footage. These systems include cameras, a power supply, monitors, a DVR or NVR for recording, and a few other elements. The cameras will capture the footage, send it to the monitor and the DVR. Footage can also be recorded and stored with cloud storage or locally.

More advanced CCTV systems can use cameras that only turn on with motion detection. Some cameras can capture video in the darkest times of day, and others can even use facial recognition technology.

Businesses will commonly place CCTV cameras at the entrances of the business and the perimeter. Cameras can also be used to monitor parking lots and a business’s interior, especially with retail establishments.

IP vs. Analog CCTV Cameras

There are several types of cameras you can use with your CCTV security system. IP and analog cameras are the two most basic categories for the cameras. It’s essential to understand the differences between the two.

IP Cameras

An IP camera is known as a network camera, and while technically it’s not a CCTV camera, they are often referred to as CCTV. IP-based security camera systems use local area networks and digital IP networks instead of being hard-wired. They can be set up to work on a company’s network, but bandwidth speeds can be a concern. Ethernet cables, such as Cat5E cables, can be used with these cameras or wireless.

Analog CCTV Cameras

The more traditional type of camera associated with CCTV systems is an analog camera. This type of camera runs with a coaxial cable connecting it to a monitor or recording system. The installation process is more difficult due to the need for more cables compared to IP systems.

Which is Better, IP or Analog?

Analog cameras offer more reliability, but IP cameras are easier to install. IP systems can be expanded easily without nearly as much trouble as an analog system. With an IP CCTV system, it’s also possible to get better resolution than an analog system. However, analog systems don’t require an internet connection, making them more secure from internet hackers.
