The TVI standard is a video transmission technology for small systems. But how does it differ from other options for equipment operation? In this article, we will explain what TVI video surveillance is and where it is applied.
Definitions and terminology
The TVI standard is an open analog video surveillance standard that transmits images in 720 or 1080p resolution.
The technology is perfect for small and medium-sized video monitoring systems, where information is transmitted over a distance of no more than 1 km. Otherwise, additional cables and noise protection are required.
As mentioned above, the TVI standard is suitable for small and medium-sized monitoring systems, where up to 100 cameras work simultaneously. Equipment for this technology can be easily upgraded, and the picture detail is increased.
There are also static and PTZ cameras for home or outdoor surveillance.
Even though analog video surveillance is a thing of the past, TVI cameras are still used. And all these thanks to the following advantages:
- TVI CCTV cameras work without signal delays;
- high throughput;
- high image quality;
- low price of cameras;
- the system is easy to install and easy to use;
- reliability and cyber security if particular software is used. More details are on the link.
Video analytics function
But analog standards have a drawback; they do not support video analytics well. Don’t expect them to have advanced AI capabilities. We think this is a significant disadvantage. After all, intellectual observation is the trend of today.
Artificial intelligence can turn an ordinary camera into a “smart” assistant for home and business. For example, a service from Faceter can:
- recognize faces and classify them according to lists;
- notify in case of detection of alarming situations;
- control access and entrances;
- help in marketing purposes for the business;
- control the quality of staff work.
But all these functions are available on IP cameras connected to the service. You cannot connect an analog device to Faceter. More details are here.
Another significant advantage of cloud monitoring is the cost of maintenance. At the same time, analog devices need monthly maintenance and manual system updates, digital technology updates automatically, and notifies in the event of an error or breakdown.
And the cost of maintaining the cloud can be zero. Read more about tariffs here.
TVI video surveillance is an analog signal transmission option. Despite its advantages, the functionality of such a system is severely limited intellectually.
It may seem that analytics is not necessary for everyone. However, thanks to the Faceter service, artificial intelligence functionality in surveillance is available to the masses at a budget price. And not using this opportunity to improve the security of your home or business is a rash decision.
