Buying an Analog HDTVI/CVI system, is like buying a betamax, analog phone and non-inverter aircon today.
Analog HDTVI/CVI vs Digital IP
- Frame rate: The frame rate of analog cameras is much lower than that of IP, so they’re not ideal for areas that have a lot of motion or that need to be seen in high detail. Compared to IP, Analog recording appear jerky, lag and slow. Images are not as sharp. You also can’t digitally zoom in like you can with IP cameras.
- Image Quality: A 2mp IP is equivalent to 4mp or even 5mp analog TVI/CVI.
- Less coverage: It may take more analog cameras to cover the same amount of area as it would take one IP camera.
- Open platform: You can use an IP camera with anything, for the most part,They’re universal. This makes it easier to add new functions to your system.
- More cables: You need a power cable, plus an expensive analog DVR cable, whereas you only need one cable with IP cameras.
- No encryption for analog TVI/CVI: A lack of encryption means a hacker could potentially access your information or replace your signal with an outside one.
- Intelligence and analytics: IP cameras are basically small computers that compress and store video, plus they can be programmed to provide all sorts of analytics. They can detect motion or smoke, count people, track certain colors, sense when something disappears, and set off alarms. You can draw a trip line where if something crosses that line, it sends a signal. All the stuff you see on CSI? That’s not analog cameras. All that fancy stuff comes from IP cameras.
