The video surveillance industry has changed over the last few years.  One major change is the increasing popularity of IP or digital surveillance systems.  Why is this happening? It’s happening because of the improved flexibility and the ease of installation provided by this new technology. More importantly, it’s more cost effective. The latest IP solutions even include intelligent video processing that can track objects.

Network attached video solutions enable you to remotely and cost-effectively monitor and secure people, property and industrial processes. You can use it to conduct remote classes, establish remote troubleshooting sessions, or broadcast sights and sounds on a Web site. Your network video system can be as simple or as sophisticated as you want it to be.
 
This is one of the major differences between the older CCTV surveillance systems and the new IP systems; the distance between camera and monitoring station and the ease of access to the video.  Analog systems are restricted by the coax cabling systems, IP cameras are as boundless as the Internet.

The network advantage: Since IP cameras are very flexible, they increase the number of applications that can be handled and provide new solutions. Simply connect an IP network camera directly to a computer network, and you'll have access to live video streams directly from your desktop using a standard Web browser. You can be on a local area network or in any location in the world via the Internet.

IP network cameras, in conjunction with IP software systems, can offer much more than CCTV solutions. IP Network video solutions also have advantages over PC-based Web cams. Some of the benefits are briefly outlined below.
Image quality: Image quality is one of the key aspects of IP network video products. IP cameras provide much greater resolution than the analog CCTV cameras.  For example, a camera has a 2 Mega pixel sensor and provides a resolution of 1600 x 1200 pixels.

There is also a choice of compression schemes used.  For example, We provides a range of video compression standards (Motion JPEG, MPEG-4 or MPEG-2) for users to choose from. In many network video products, both Motion JPEG and MPEG-4 are supported simultaneously. This enables you, for example, to view at full frame rate with MPEG-4 and record at the same time with Motion JPEG, allowing for optimization in image quality and bandwidth.

Wide ranging network video products: You can find fixed network cameras for both indoor and outdoor applications, as well as pan/tilt/zoom and network dome cameras that enable remote control of pan, tilt and zoom functions over IP networks. There are also video servers that allow analog CCTV systems to take advantage of the benefits of a digital, networked world. Video management software Video management Software and accessories such as network camera housings and devices that bridge between analog and digital are also available.


Audio: Besides being able to see remotely from any networked computer, anywhere and at any time, many IP cameras also provide two-way audio communication over networks. This allows you to not only hear what's going on remotely, but also speak through the network. With both visual and audio communication, you can question intruders or broadcast both sights and sounds from a location or event on Web sites.

Event functionality: IP network cameras with IP software enable users to set and manage alarm events. Once an alarm is set, either as scheduled, or via input/outputs, or video motion audio detection, you can automatically request that certain actions occur; for instance, start sending and recording images to specified destinations, send alerts to specific individuals via e-mail or SMS to a mobile telephone, activate lights, turn alarm on or off, open or lock doors, control temperature levels etc.

Triggering mechanisms: A wide range of triggering mechanisms (whether built into the product or available in a software package) can be incorporated into an IP network video system. 

Schedule: You may schedule a time for the network video product to perform certain actions; e.g. start sending and recording images every evening, on weekends or on holidays. 

Inputs/Outputs (I/O): Many IP network cameras and video servers have input/output ports that can be connected to doorbells, detectors (e.g. smoke, movement, sound, and temperature sensors), lights, switches and alarm relays. When input mechanisms are triggered, you can automatically alert someone.

Video motion detection: This feature essentially allows you to define areas of a screen where you want to detect any visual changes. When a change is detected, you may request a number of things to be done automatically.

Recording: Video can be stored in the hard drive of your computer or even in a hard drive located in the camera. Special IP Software makes it very easy to manage the cameras, store and view the video. See video management software for more information about software available.

 Power over Ethernet: With a network video solution, you have the option of using the same Ethernet cable for data communications and power. This feature makes it easier to install products since an electrician is not required and the network video product is able to operate even when there is a power failure.

Security: IP network video products provide many security features; among them, different levels of password protection and water marking of video. For example, using predefined passwords, certain people may only have the rights to view live images with no access to the product's configuration, while the administrator would have full access to configure the product's settings and security features. Another security feature is IP address filtering, which allows only predefined IP addresses to access the product. Some products also provide HTTPS for encrypted communication.
