What is the difference between a Security Camera, Surveillance Camera, and CCTV Camera?
The term Surveillance Camera is commonly used to describe a camera that is being used to monitor employees, business operations, secure assets, monitor processes and deter theft. The term Security Camera refers to the same type of camera but the camera is being used for security purposes such as monitoring the perimeter of a home or building. In other words, the term used to describe the camera is usually an indication of the intended use.
The term CCTV Camera is a generic term used to describe the security and surveillance industry in general. CCTV stands for Closed Circuit Television. All security and surveillance camera technologies (analog, coax, IP, PoE and wireless) can be accurately called CCTV cameras because they do not openly broadcast their video feed without some level of security, the video feed is "closed circuit".
The different technologies on the market can be categorized as follows:
Coax - Analog, TVI, CVI & AHD
These types of cameras exclusively use RG59 or Rg6 coax cable to transmit video from the camera to the video recorder, and a two conductor copper wire to deliver power to the camera. Coax was the original transmission technology and while new digital coax cameras and coax DVRs are available to upgrade old coax systems. This technology is in twilight and we highly recommend considering a PoE or network based technology for new installations.

Cat5 & Cat6 Cable - IP, PoE and Network
These digital high performance cameras use standard network cabling to transmit video to and NVR and deliver power to the camera. IP based camera systems IP based camera systems offer the best resolutions, the fastest frame rates and the most flexible design options. We highly recommend this technology for all new home or business installations.
Wireless & Wifi
Wireless cameras use the same technology as wifi networks. They are secure as long as you protect your passwords. Many claim digital wifi cameras can be hacked, but from our experience, when you dig into the details, the user or owner never changed the factory default password in the camera allowing bad actors to access the video feed with the publicly known factory password. Wireless is for convenience, not performance. While wifi technologies are getting better and better, they still lag behind in performance and reliability compared to PoE network based system.
