Potential advantages of IP Camera
A growing branch in CCTV is internet protocol cameras (IP cameras). IP Cameras use the IP protocol, used by most LANs to transmit video across data networks in digital form. As it's IP, video can also, but not necessarily, be transmitted across the public Internet, which allow homeowners and businesses to view their camera(s) through any internet connection available through a computer or a 3G phone. For professional or public infrastructure applications, IP video would always be restricted to within a private network or VPN.
Internet protocol is a protocol used for communicating data across a packet-switched network using the internet protocol suite, also referred to as TCP/IP.
Potential advantages
The following are potential advantages of IP cameras over traditional cameras:
Two-way audio via a single network cable, allowing users to communicate with what they are seeing (e.g. gas station clerk assisting a customer on how to use the prepay pumps)
Higher image resolution: IP cameras have a resolution of at least 640x480 and can provide multi-megapixel resolution and HDTV image quality at 30 frames per second.
Flexibility: IP cameras can be moved around anywhere on an IP network (including wireless).
Distributed intelligence: with IP cameras, video analytics can be placed in the camera itself allowing scalability in analytics solutions.
Transmission of commands for PTZ (pan, tilt, zoom) cameras via a single network cable.
Encryption & authentication: IP cameras offer secure data transmission through encryption and authentication methods such as WEP, WPA, WPA2, TKIP, AES.
Remote accessibility: live video can be viewed from any computer, anywhere, and also from many mobile devices including iPhone, iPod touch, and Windows Live Messenger on selected cameras.
Cost-advantage for larger systems. Studies show that for systems with less than 16 cameras, analog technology is cheaper, between 16 and 32 they are equal, and beyond 32 cameras, IP-based systems are more cost-effective.
IP cameras are also able to function on a wireless network. Initial configuration has to be done through a router; after the IP camera is installed it can then be used on the wireless network These cameras are used in navigation purpose in defence forces.
PoE - Power over ethernet. Modern IP cameras have the ability to operate without an additional power supply. They can work with the PoE-protocol which gives power via the ethernet-cable
