Advantages:

• Analog security cameras are less expensive compared Network IP Cameras
• maximum transmission distances are approximately 300 meters over coax cable or 1.5 kilometers over twisted-pair (Cat 6) cable using video balun.
• Audio-over-Coax is able to transmit audio and video over the same coaxial cable
• Easy to install everyone / Simplified setup process
• It demands less bandwidth than IP camera systems
• The technology support enable the use of 4K high-resolution analog cameras

Disadvantages:

• Analog security camera systems require more storage space than IP security camera systems (Video compression)
• Requires both a coaxial cable and power cable for each camera, unlike IP cameras that use a single PoE cable
• Typically, lower image quality and frame rates lead to potential blurriness or graininess in high-motion areas
• Analog camera cabling/Wiring expansion costs are higher compare IP cameras because of the wiring required for each camera from the DVR.
