Benefits of IP
Capable of higher resolutions than traditional analog solutions
Transmit power, video and data over single Ethernet cable
IP camera can operate as a standalone network device, capable of functioning without a network video
recorder
Limitations of IP
Require a complex network infrastructure
Offer limited transmission distance
Commonly experience video latency
Require considerable network bandwidth
Can be extremely costly compared to traditional analog and comparable Analog HD systems
Benefits of Analog CCTV
Simple to install, operate and maintain
Affordable compared to traditional IP solutions
Universally compatible with other analog technologies
Limitations of Analog CCTV
Analog CCTV cameras offer limited resolution (up to 960H, or 960 x 480 pixels)
Insufficient resolution for applications requiring greater levels of detail, such as facial recognition or license
plate identification
The Benefits of HD Analog Technology
Megapixel Resolution
Simple Installation
Zero Latency
Low Cabling Requirements
Longer Transmission
Transition Friendly
Cost-Effective
