A Network IP Camera is a stand-alone device which allows a user to view live, full motion video from anywhere on a computer network, even over the Internet, using a standard web-browser.
No. DVRs or Digital Video Recorders are only used with the older analog CCTV systems. Analog cameras connect to the DVR using a coax cable and BNC connector. IP cameras connect right to your network like another computer. They have a RJ45 connection on the back, not coax. The video is stored on your computer’s hard drive rather than a special DVR storage system.
No, some network cameras have an embedded OS (operating system) as well as an embedded Web server. To be called a Network IP camera, the only requirement is that the camera connects to the network, and not a computer - an embedded OS is what separates network cameras.
An IP Camera is a true networking device containing an embedded OS (Operating System), supports multiple users, and can be viewed using any web browser. It does not require additional hardware to operate and therefore has the flexibility to be located anywhere with a network connection. A web cam must be connected to a host computer, supports only one user at a time, and cannot be shared on a network. Only the host computer can access the web cam.
Network Attached or IP cameras connect to the network with their own IP address while the analog CCTV cameras connect to a CCTV monitor using coax cables. The IP camera has intelligence and can be connected to the network without the need of a PC. Major advantages include choice of very high-resolution cameras (2048 x 1536 compared to 700 x 480 resolution of CCTV cameras), the ease of adding additional cameras (just connect another one to your network), viewing the cameras from anywhere on your network or even over the Internet and much more.
No, you of course, can have a real, public, static IP address for each camera, however, using just one static IP address for your router and a virtual server or port forwarding scheme, you can use many cameras with just one static IP and just about any router. Please also note that the IP camera must have an adjustable web server port (you must be able to change the web server port) to use multiple cameras behind a router.
Yes, it acts as a standalone web-server, with some limited memory space reserved for your own web pages.
Advanced Network IP Cameras utilize CS-mount lenses, which can accommodate a variety of specialized lenses, such as wide-angle, fish-eye or telephoto lenses.
Yes, if the cameras use MPEG4 compression and support audio. For example you can use the IP3111 which has a built-in microphone and provides simultaneous transmission of both audio and video can be used. Just remember that you need a high speed connection between the two locations to handle the bandwidth of this high frame rate video.
A Video server, is the popular expression for a Web attached Video Server, connected to a digital network, i.e. LAN. The purpose of the Video Server is to, automatically or on request deliver live video to you browser or other applications over a digital network. This server function can also be integrated into a network attached (or IP) camera.
The purpose of a Video Server on the network is to provide a very easy way of distributing live pictures so they can be viewed by any computer on the network or Internet. There is no need for a separate Video surveillance system with coax wiring and dedicated monitors tucked away in a security office.
The same topology limitations that apply to any 10/100 Ethernet card apply, meaning the maximum segment length is 100 meters from switch/hub to the camera.
Network IP Cameras equipped with DivX compression technology can store almost a month of continuous video on a 20-gigabyte hard drive.
Power-over-Ethernet (PoE) or "Active Ethernet" eliminates the need to run power to devices on a wired LAN. Using Power-over-Ethernet, installers need to run only a single CAT5 Ethernet cable that carries both power and data to each device. This allows greater flexibility and significantly decreases installation costs in many cases.
