For years, HD resolution and single cable signal/power were IP camera advantages, with analog cameras limited to much lower resolution and requiring separate power and video cables. However, in new HD analog cameras, AHD, CVI, and TVI have made significant advances, with resolution similar to IP, single cable power up the coax, and more.
In this report, we examine AHD, CVI and TVI, including their latest generation advances, compared to IP cameras, including:
- HD analog variants: AHD, CVI, TVI
- Encoding / transmission differences between IP and HD analog
- Advantages and disadvantages of encoding in the camera
- Resolution differences between HD analog and IP
- Advanced features: I/O, audio, camera side motion, etc.
- Recorder compatibility
- Coax compatibility
- Power over Ethernet (PoE) vs. Power over Coax (PoC)
- Vendor support of HD analog
- Cost differences between analog and IP
