Currently system Camera CCTV was gradually shifted to using IP technology, because using this technology, the manager will be more focused, more convenient and cost for installation is much reduced ,accompanied by the image quality, the controls will better:
- Flexible Scalability, unlike analog camera system,when you need to expand the recorder, hard drive, go much line.When using ip camera system you can expand the system quickly, the number of cameras can be up to hundreds or thousands of cameras in a system of centralized management and more convenient ... .
- Speed faster signaling system similar
- Camera is much more intelligent functions are integrated by many intelligent software, image obtained thanks sharper video processing technology of computer, overcoming the limitations of the color system PAL / NTSC
- Saves installation costs: ip camera only by 1 or 2 wires for transmitting audio signals, images, PTZ control, if users type power supply system through internet you only need one wire UTP savings over analog camera system and a lot of common parts of the building infrastructure systems often have LAN / WAN up to 50%
- Use the ip camera system will be easily combined with other security systems such as internet access control systems, alarm systems, fire alarm.
- High reliability due to your data can be recorded in anywhere with internet access to search for convenient and fast
For a quick comparison you see the comparison table below:
Model 2 system
A. Analog Camera System
B. IP Camera System
Conclusion:
- Generally analog camera system used for monitoring the scale small and difficult to expand, management does not focus
- IP Camera Systems are often used for monitoring large-scale, centralized management, carried out the investment costs of large IP system many times more expensive than a combination of IP and analog signal transmission distance and the shorter cable network coaxial cable ....
