The digital, network video surveillance system provides a host of benefits and advanced functionalities that cannot be provided by an analog video surveillance system.
The advantages include:
Superior image quality
Easy, future-proof integration
Scalability and flexibility
Easy, reliable installation
Analog video still has an important role to play in the security industry, for now. It is still the best choice for a security system that extensively uses pan/tilt features and is also more effective than IP cameras in low-light environments. Digital video is quickly catching up to the old standard though and it is only a matter of time until IP cameras become the superior, cost-effective solution here, too.
However, the lower costs coupled with the simple and reliable design make analog cameras the choice of most home or apartment owners.
