Camera Technology Come in Two Flavors.
CCTV Cameras
CCTV, or Closed-Circuit Television cameras broadcast its analog signal in a closed circuit environment to designated surveillance monitors.
CCTV cameras were the first cameras used for surveillance purposes and were first used in some cities since the early 1960's.
The DVR (Digital Video Recorder) is only way that CCTV cameras can be recorded today, albeit in the early days tape cassette analog video recorders were the technology that was commonly used for recording.

CCTV cameras by themselves cannot be access remotely by outside means unless it's connected to a DVR (Digital Video Recorder) in which some DVR models have optional connectivity via Ethernet LAN, and/or the Internet.
CCTV cameras uses round BNC connectors which were originally developed for the U.S. military during WW2. But today it's used mainly in some video equipment, recording studios, as well as the CCTV cameras.

CCTV cameras are cheaper than IP cameras because it is an older technology but in some cases or applications CCTV cameras are a better fit than IP cameras.
IP Cameras
IP cameras, uses the IP or Internet Protocol to transmit its signal via the Ethernet cables. The IP camera technology first came out in the late 1990's. And, during its first decade or so it was used mainly as a means to do video calls between two remote parties using a computer and a video calling software.
But over time as the hardware and software technology got better it naturally entered the surveillance camera arena where the CCTV technology was the only dominant player for many decades.
One advantage that the IP cameras have over CCTV cameras is just like a computer IP cameras can save recorded files in any format or medium that any computer can read, write, and save. The recorded files can be save on its built-in local SD drive; on the user's PC, or to a dedicated storage server in the network, or even to a cloud-based storage site that's half-way around the world.
Unlike the CCTV cameras, IP cameras uses Ethernet cables rather than BNC cables to transmit it's data over the LAN (Local Area Network) or even through the internet if the network is connected to it. And, because Ethernet cables have 8-wires inside them it can transmit other commands to the camera, such as changing the direction of its field of view if the cameras are attached to motors, or make some changes to its detection sensors if the camera is equipped with different sensors.
IP cameras can also be powered directly through its Ethernet cable without the need of having a nearby power socket. These types of IP cameras are called POE IP cameras, POE is short for "Power Over Ethernet".
The downside of IP cameras is that it can easily be hack if it's not properly setup behind firewalls and routers, and the password it uses are still on factory default or users give it weak passwords.
