Analog CCTV Security Camera Buying Guide


Our comprehensive buying guide features everything you need to know about analog security cameras, so you can make an informed buying decision.

What is Analog CCTV Technology?

Let’s start with a little history. Analog Closed Circuit Television (CCTV) technology was the first video security camera technology. Analog CCTV has long been a trusted and reliable security solution for a variety of surveillance applications, and many homes and businesses have a legacy analog security system in place. Analog cameras provide an easy-to-install, cost-effective, reliable video surveillance solution.

How Does Analog CCTV Technology Work?

Analog cameras process and transmit analog video signals within a specified ‘closed circuit’ area to a monitor for local central viewing from one location. Analog cameras can be connected to a digital video recorder that enables the analog signal to be converted to a digital video signal. A DVR takes in analog camera signals from point-to-point coaxial cables, converts the analog signals over to a digital signal, and records it to a hard drive. The encoding and processing of the video signals happens in the DVR versus the camera.

Analog Camera Considerations

Before you purchase an analog CCTV security camera, it’s important to determine your needs:

  • What’s your security application?
  • Will you be monitoring indoor or outdoor environments?
  • Do you want a wired or wireless camera?
  • What level of detail do you need to see?
  • How many cameras will you need?
  • What camera form factor is best for your application?


Do You Need an Indoor or Outdoor Camera?

If you plan on monitoring outdoor locations, you’ll need a camera with a weatherproof enclosure, one that has an appropriate IP weather rating and is able to withstand extreme temperatures and element such as rain. If you need to target high crime areas that are prone to vandalism, you’ll want a vandal-proof camera. Take a look at the security camera specifications to make sure you get the appropriate camera for your application.
