ANALOG CAMERA SOLUTIONS

CCTV solution today uses two main technologies: CCTV technology (called Analog Camera) and CCTV technology (IP Camera for short). The main distinguishing features of these two CCTV systems are as follows:

Analog CCTV system:

In the traditional analog CCTV application, the cameras capture the analog video signal and transmit the analog signal over the coax cable to the digital video recorder (DVR). Each camera can be powered up by providing DC power directly at the camera or by using common signal and power adapters on CAT5e cables. The DVR converts the analog signal into digital, compresses the signal and then stores it on a hard drive for later viewing. Intelligent features are built into the DVR to handle things like recording scheduling, motion detection, digital zoom, etc. The monitor is connected directly to the DVR, or it is. can be set up to transmit signals over a local network or the Internet for viewing on a computer or smartphone. When the signal travels over the local network environment or the Internet, the video signals of all cameras are transmitted in the same data stream - video stream (with the same IP address). In addition, the DVR also compresses the camera signals (the popular compression standard is H.264) to minimize the bandwidth of the data stream when transmitting over the IP network, so it is very effective in saving. bandwidth.

IP CCTV system:

In the IP world, each IP camera will also capture the analogue video signal, but it instantly converts to a digital signal inside the camera. Some digital processing can take place immediately upon entering the camera, eg compression and motion detection, etc. This digital video image is then transmitted over the IP network using Ethernet communication ( CAT5). The camera power supply can be supplied directly from DC power or can be supplied via an ethernet cable using Power-Over-Ethernet (PoE) technology. As with all network devices, each IP Camera is required to set its own IP address and related identifiers.

Management software is required to be installed on the computer you want to monitor the IP cameras' images. A high-powered computer is set up with the appropriate management software to record all the surveillance images of the IP Camera system. Or it can be a network recording device that performs general storage and monitoring functions for the provider's IP camera system (referred to as NVR - Network Video Recorder). Usually surveillance software installed on PC or NVR will have to be the same manufacturer with IP camera due to the inconsistency in production standards of different suppliers.

The IP camera signals that are transmitted over the Internet are similar to the way a DVR signal works. However, each IP camera is a separate signal stream and has its own IP address or gateway. This can greatly affect the bandwidth used when viewed from a distance.

CCTV system combining Analog and IP:

A better solution that can be used to solve the above problem is a solution that combines the use of analog and IP technology. The solution combines the benefits and advantages of analog and digital surveillance technology. This method allows you to use a combination of analog cameras and IP cameras, digital video recorders (DVRs), and IP camera servers. This powerful solution is perfect for large and expanding businesses such as restaurant chains, medical buildings, schools, or large offices or industrial environments.
