It is important to note that there are two main closed-circuit television (CCTV) systems out there. The one you choose will be the deciding factor in the type of equipment you get.
The two systems are the Analog and IP CCTV security camera systems. The main difference is in how they transmit their signals and process them.
There are five main types of equipment required and each comes with different considerations to account for. These include:
A good place to start is the cameras. These are an integral part of your system since what they are able to record dictates what you will be able to see. There are many types of surveillance cameras in the market.
Other considerations include video quality which will inform on the size of storage required.Storage
A high-resolution image will require more storage. Home security camera systems require less storage than CCTV security cameras for businesses. The recommended storage is 60GB – 240GB per camera installed though this can vary widely depending on your needs and system specifications.
Factors affecting storage requirements include resolution, field of view, frame rate, and motion detection features. The higher the value of any of these is the more storage you require.Video recorders and Cabling
This refers to the aforementioned Digital video recorders and Network video recorders whose main role is to store the data from the cameras. Furthermore, both analog and IP CCTV security cameras require different cables as stated above.Monitors
This is largely dependent on the customer and can range from something as simple as a smartphone to a series of wall-to-wall monitors. The monitor you choose should however be compatible with the CCTV camera that you use. It would be unintuitive to record with a high-quality resolution camera only to watch the feed from a lower resolution monitor.
For home security camera solutions, the analog option carries the benefits of being cheaper and easier to install. This is despite all the cabling required.
Commercial CCTV security camera systems will find IP CCTV systems more suitable because of easier scalability, remote access, wider coverage, and superior video analytical capabilities at higher resolutions.
