Of course, the image can be accessed online, depending on needs and system. If you have one, a server can choose a stand-alone DVR (Stand Alone Digital Video Recorder).
How to realize transmission from the server room?
Method 1: UTP Cable Method 2: coaxial cable Method 3: Wireless Method 4: Fiber Optic
The assessment should to be taken based on the available resources.
Areas of deployment
It can be installed inside and outside. CCTV cameras that are used outdoors should be more resilient than cameras that are indoors. Some cameras are may see in the dark through the use of infrared.

The CCTV cameras are digital and this is the reason they offer a very high quality of the image and all the information is digitally stored on the hard disk.
