Analog and IP arethe main 2 kinds of CCTV systems. In a previous post, we contained the basicelements of an analog system and how it is set up. In this post, we will go over all the essentials of an IP CCTVsystem.
HOW IT WORKS: ANALOG VS. IP
The major differencebetween analog and IP CCTV systems is the way video data is transferred and administered.In the form of video signals, analog cameras record the image which is then transferred via coaxial cables to the DVR. The DVR then procedures the signals and covers them into digital video with a linked monitor that can be viewed.
All the datatransmission is done through the linked network with an IP system, instead ofcoaxial cables. Furthermore, for DVR the IP cameras do all the processing of video signals so there is no need. To NVR IP cameras are linked, but this device is only for collecting and viewing the footage, not for processing. Consumers can access and view their camera footage remotely through the internet since the CCTV system is linked to a network.
BASIC IP CCTV SYSTEM SETUPS
- With PoE
There are manymethods to set up an IP system. Utilizing Power over Ethernet (PoE the firstcouple of systems that we will go over include), since these are more popular. Non-PoE cameras will typically need 2 cables: to the video recorder, one will be linked to transfer data while the other cable will be linked to a power supply. PoE will only need one Ethernet cable that can communicate both data and power. The camera will get its power from the PoE device it is linked to instead of being linked to a distinct power supply.
- Without PoE
The simple setupwill be the same as the first PoE setup that we protected if you decide toinstall a non-PoE system. The only discrepancy is that each camera will also require to be plugged into an external power supply.
Conclusion: Basic IP system setups can be done in two ways oneis with PoE without PoE. All these types is having different use. Users cangain access to and view their camera footage remotely through the internet since the CCTVCamera system is linked to a network.
