An IP Network Video Camera is a Video Camera with a built in web server that can be controlled, monitored and viewed from virtually any location via High-Speed Internet Access.
A Network Camera has its own IP Address and built-in computing functions to handle network communication. Everything required for viewing images over the Network is built into the unit. An IP Network Video Camera can be described as a Camera and a computer combined. It is connected directly to the Network as any other network device and it has built-in software for a Web server, FTP Server, FTP client and e-mail client. It also includes alarm input and relay output as well. More advanced Network Cameras can also be equipped with many other value-added functions such as motion detection and an Analog Video Output.
The Network Camera's camera component captures the image, which can be described as light of different wavelengths, and transforms it into electrical signals. These signals are then are converted from Analog to Digital Format and transferred into the computer function where the image is compressed and sent out over the network.
The lens of the Network Camera focuses the image onto the image sensor (CCD). Before reaching the image sensor, the images pass through the optical filter, which removes any infrared light so that the "correct" colors will be displayed. The image sensor converts the image, which is composed of light information, into electrical signals. These electrical, digital signals are now in a format that can be compressed and transferred over networks. The Camera functions to manage the exposure (light level ofimage), white balance (adjusts the color levels), image sharpness, andother aspects of image quality.

A single camera setup
- The camera turns video & audio into data
- The camera connects to your Network or direct your Router and transmits this data onto the network
- This data can then be viewed as high quality images, and audio on any authorised PC, Mac or Mobile Phone; on the local network, or over the internet
- The Recording Software supplied can be used to record and view up 64 cameras on any compatible Windows PC or Laptop.
- Each camera turns video & audio into data
- The camera connects to your Network via a Network Switch and transmit their data onto the network
- This data can then be viewed as high quality images, and audio on any authorised PC, Mac or Mobile Phone; on the local network, or over the internet
- The Recording Software supplied can be used to record and view up 64 cameras on any compatible Windows PC or Laptop
- In the example below each site has 2 IP cameras
- At site 1 the cameras are connected to the local network and recorded on a Laptop running the Xvision Recording Software
- The cameras are also connected to the Internet via the router
- At site 2 the cameras are connected to the Internet, no local recording or viewing is taking place
- At Head Office the cameras are being recorded and viewed live on a Laptop running the Xvision Recording Software
- The cameras can also be viewed from an iPhone (over 3G) by the Managing Director when he is out of the office.

IP CCTV systems run over existing IP networks, wired or wireless, this makes wiring IP CCTV systems simple, causing less disruption, reducing the time required to install them and minimizing unsightly cables. For anyone familiar with networking, setting up an IP based system is simple with intuitive operation and evaluation. Simple 1 camera systems only require an IP Camera connected to a network/internet connection, and they can then be viewed by a PC using Internet Explorer. If POE (Power over Ethernet) IP cameras and networks are used then the IP CCTV cameras do not even need separate power, they can be powered via the network cable.
Better System Integration
IP CCTV systems communicate using IP, allowing them to integrate and co-exist on the same network/cabling as other IP based systems, such as Access Control and IP Phone Systems etc... Integration also means that these different systems can work together, for example an IP camera picking up movement will be able to transmit images of that movement to an IP Video Phone automatically. IP systems also allow the direct use of IP-based services as standard such as e-mail or image sending via FTP.

Amazing!Really, it's effective! Multi-site video surveillance has now become one of the most important needs of almost every business. It is very effective in home security as well. For ideal working internet connection is mandatory for this.
These Lock Systems Replacement Parts the traditional keys with better and more secure automation features like remote locking and unlocking. In these locks, a latch or bolt is made to cross the opening between the side of the door and the doorframe, thereby preventing access. Digital Door Locks, also known as keyless doors, the locks replace the keys with a digital screen, where you can put numeric digits as a code. On pressing the specific password, the locks get active and unlock. Unik cctv legacy continues to ensure a high degree of security to consumers with the implementation of latest technology and constant innovation.
