Q:What is the difference between web camera and IP camera?
A : A web camera is connected to a PC, normally through USB, and uses the PC to make video available to other viewers. It will not work without a PC locally connected to the camera. An IP camera usually stands alone, and combines the functionality of a high-end web camera, the PC and network interface into one network-ready product.
Q: What is IP Camera?
A: IP is an abbreviation for Internet Protocol, the most common protocol for communication over computer networks and the internet. IP Camera is a camera that creates digitized video streams and transfers via a wired or wireless IP network, enabling monitoring and video recording as far away as the network reaches. In other words, using an IP camera can save a lot of money on installation since most facilities are already wired with LAN cables. Wiring coaxial cables is the major expense when implementing analog cameras. Also, it allows users to have a camera at one location while view live video at another location over the network / internet.
Q: What is 960H, D1 and CIF resolution?
A: The 960H resolution is 960x576 in PAL and 960x480 in NTSC. It is the maximum resolution for the analog CCTV system. The D1 resolution is 720x576 in PAL and 720 x 480 in NTSC. The CIF resolution is 352x288 in PAL and 320x240 in NTSC.
Q: Do I need to have internet access to use the cameras?
A: No. The camera works fine also in local network without the internet connection. If the remote users are in the same local network, it is unnecessary to connect the IP cameras to the internet.
Q: Why is it so important to have DDNS support in IP camera?
A: If an IP camera can support DDNS (Dynamic Domain Name Server), users can set the IP camera at a virtual domain name (such as cam1.kitchen.Taipei.xxx.xxx) at dynamic IP, and be able to view this IP camera anywhere that has access to the internet. It saves money when setting up the broadband with service provider, whether it is ADSL or cable modem, since fixed IP is not a must.
Some IP camera manufacturers claim to provide DDNS. However, they are software solution that needs to be installed at client site PC. Therefore, it requires users to see those IP cameras at the PCs that have installed the specific AP from manufacturers. This is not as user-friendly. The IP Camera have DDNS function built-in the IP camera so that users can view the IP camera from anywhere.
