IP is an abbreviation for Internet Protocol, the most common protocol for communication over computer networks and the Internet. IP Cameras create 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 analogue cameras. Also, it allows users to have a camera or multiple cameras at one location while viewing live video at another location over the network / Internet.

Q2: What is the difference between a web camera and an IP camera?

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.

Q3: How much bandwidth does an IP Camera need?

It depends on both the resolution and frame rate. It also depends on the compression technology the IP camera is using. The table below shows the two most popular compression technologies, their required bandwidth and other useful information.

Also, please note that 25 frames per second is the required frame rate to provide continuous motion and DVD quality video.

Q4: Can I save video from the camera?

Yes. You can record the video at remote / local by using Xview Recording and Viewing Software. The ability to record the video at a remote site is a major advantage of IP cameras over traditional analogue camera.

Q5: Do I need to have Internet access to use the cameras?

No. The camera works fine also in local network without the internet connection. If the remote users are in the same local network, it's not necessary to connect the IP cameras to the internet.

Q6: Do these cameras support wireless LAN?

The XIP3000 does not support wireless LAN (WLAN), however the XIP3001 and XIP3101 both support wireless LAN.

Q7: Why is it so important to have DDNS support in an IP camera?

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.london.xxx.xxx) at dynamic IP, and be able to view this IP camera anywhere that has access to the internet.

Some IP camera manufacturers claim to provide DDNS. However, they are software solution that needs to be installed at client site's 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. XIP3000 cameras have DDNS function built into the IP camera so that users can view the IP camera from anywhere. Please note that you have to sign up for DDNS service with the service provider first.

Q8: Do Xvision's IP cameras provide motion detection function?

Yes. Xvision's IP camera provides built-in motion detection function in the IP camera, not in the AP installed at client site. If the motion detection is in the AP, there will be a delay between the time the event occurred, and the time the camera reacts.

Q9: What kind of software is provided by Xvision together with IP camera?

Xvision XIP3000 cameras are shipped complete with Xview Viewing and Recording software.

Q10: What are the applications for IP cameras?

IP cameras can be used in professional security systems and enable live video to be viewed remotely by authorized personnel. The IP cameras are easily integrated into larger, complex systems, but can also function as stand-alone solutions in entry-level surveillance applications. IP cameras can be used for surveillance of sensitive areas, such as buildings, casinos, banks and shops . Video of those areas can be monitored from relevant control rooms, at police stations and by security managers from a variety of locations. IP cameras are also effective substitutes for analog cameras in traditional law enforcement applications, such as keeping public places safe. IP cameras can be used for access control . People as well as vehicles can be recorded with time stamps that are easy to locate and review. The images can be stored in a remote location, making it impossible to steal the information.

IP cameras are easily connected to the existing IP network and enable real-time updates of high-quality video to be accessible from any computer on the network. Sensitive areas such as the server room, the reception area or any remote site can be closely monitored in a cost-effective and simple way, over the local network or via the internet. IP cameras enhance the monitoring of a retail location by ensuring that everything is in good order. An IP camera is a useful tool at the office . Areas like the reception area, and conference rooms can be monitored for activity. In addition, users can keep track of who has been in the server room and take appropriate action when problems occur. IP cameras are useful tools for the manufacturing industry. Monitor robots, other machines and production lines from the office or home and allow service engineers to access the cameras remotely. With Pan/Tilt/Zoom cameras it is possible to look at comprehensive as well as detailed views.
