1.网络摄像机:
IP 摄像机是一种用于监控的数字视频摄像机,它通过网络以太网链路传输数据,也称为 Internet 协议摄像机。 IP 摄像机安全系统提供了比传统闭路电视摄像机安全系统更好的安全性和许多附加功能。 IP 摄像机提供高质量的视频信号,并允许通过网络以太网链接传输信号或数据。

2. 闭路电视摄像机:
闭路电视摄像机是一种用于监视的数字摄像机,它传输信号以在监视器上观察,也称为闭路电视。闭路电视摄像机网络构成了一个完整的安全系统,信号被监控和记录,这些视频信号不会公开分发给外部接收器。

网络摄像机和闭路电视摄像机的区别:

S.No. IP CAMERA CCTV CAMERA
01. IP Camera also known as Internet Protocol camera. CCTV Camera also known as Close Circuit Television.

05. IP cameras offer higher resolution video and better picture quality than CCTV cameras. CCTV cameras offer lower resolution video and less picture quality than IP cameras.
06. In this system multiple number of IP cameras can be added. In this system limited number of CCTV cameras can be added.
07. Creating an IP camera security system needs less cost than creating and maintaining CCTV camera security system. Creating a CCTV camera security system needs more cost than creating and maintaining IP camera security system.
08. IP cameras use Wi-Fi, LAN or cellular network for connectivity. While it uses a television to broadcasts signals.
