Video Technology

Analog or IP video camera functionality falls into two broad categories:

Fixed

Typically for entry doors, hallways, gates, etc.

Pan-Tilt-Zoom (PTZ)

Typically used in retail, casinos, etc. where the ability to change camera view is required and the cameras are actively monitored/controlled

Video Security & Surveillance Realities

Ever increasing reach of surveillance

~Leading to quality, bandwidth, and transmission distance issues

~Beyond the reach of traditional copper (coax or UTP) cabling

~New camera locations may require new cabling

Many IP camera installations co-exist with analog camera networks

~Cabling mismatch if upgrading cameras

~Extended reach of network beyond original design for new cameras

 

Copper-based cabling limitations

Limited transmission distances

~Coaxial cable < 228 meters (750 ft.)

~UTP cable < 100 meters (328 ft)

~Requires more equipment or signal conditioning / amplification to increase distance

Susceptible to electrical interference

~Noise, high voltages and ground faults

Quality and security risks

~Quality effected by distance and interference

~Copper-based cabling easy to tap into
