Simple monitoring / recording systems with cameras, monitors, and recorders.

Simple monitoring / recording systems with cameras, monitors, and recorders.
Large scale systems linked to other systems.
Large scale systems combining multiple remote site monitoring and remote data access.

Relatively inexpensive (Manufacturers have full lineups, systems are fully developed overall)

Relatively expensive (Manufacturers are competing to develop and launch new products, many with highly advanced function.)

System configuration and monitoring style firmly established. New functions and dramatic developments - not much expected in future.

Dramatic developments expected in future. (Higher resolution, new functions)
Diverse applications beyond monitoring

NTSC or PAL

Variable. Depends on camera specifications. (Trend is toward high resolution.)

30 frames standard

Variable

No

Yes (Transmission speed varies depending on network environment.)

Yes (More deterioration at greater distances)
