The IP Way:

How it works

Protecting existing CCTV investments

Significant investments in analog CCTV systems may have already been made. The technology shift to net- work video does not, however, mean that existing ana- log CCTV investments have to be discarded. With an Axis network video solution, you can integrate your existing analog system into an IP-based solution. The solution enables you to take advantage of numerous functionalities such as remote pan/tilt/zoom, Power over Ethernet, audio, video motion detection, while meeting user requirements for image quality, recording capabilities, reliability, and cost-effectiveness.

Leveraging IT investments and achieving a lower total cost of ownership

The majority of businesses now have high-speed, IP- based networks connected to the Internet. Adding an Axis network video system simply utilizes and extends the same infrastructure to include video functionality. Standard IT equipment such as switches, PC servers for video recording and storage, are used, so existing in- vestments in IT infrastructure and devices can be lev- eraged, ensuring high return on investment.

A more secure system

Network video offers more ways to secure access to video than can be provided by an analog CCTV system. Passwords can be used to limit access, and video can be encrypted before being sent over the network to make sure it cannot be viewed or tampered with. The system can also be set up to authenticate the connection using encrypted certificates that only accept a specific network video device, thus eliminating the possibility of anyone hacking into the system.
