Do you know what DVR is? Do you know what it is for and how to choose? The DVR is widely used in homes, businesses and you probably also need one, but you still did not know that.
In today’s post you will find out what DVR is and how to choose a good one. Follow the text and find out everything you need to know about DVR!
WHAT IS DVR?
DVR is an acronym in English that can be translated as a digital video recorder. It is a device that receives images captured by a camera, integrates the images into the system, decodes the received signal and records all the information on a hard disk.
Besides recording the images from security cameras, the DVR makes managing such files possible. Being a device that operates without a computer, it has also become known as “stand alone”.
WHAT IS IT FOR
Now that you know what DVR is, you need to understand its utilities. It is widely used to record television shows that one wants to watch later, being offered by pay-TV companies.
However, its main use lies in security cameras that compose Closed Circuit TV (CCTV). The DVR is the device responsible for storing the videos and images captured by the camera.
THE EVOLUTION OF THE SYSTEM
There are a number of options for DVRs with different functions required in each situation, such as image quality, price, remote access and connectivity with old cameras and systems.
This variety makes the system evolved and inclusive. Some options, which require more modern cameras and allow remote access, are usually used in shops and condominiums. Others allow integrating old and new cameras to take advantage of an existing system, for example.
WHAT TO CONSIDER WHEN CHOOSING YOUR DVR
ORIGIN AND WARRANTY
Choose good brands as they provide warranty and technical support so that you receive service whenever you need it. The ideal is to opt for products with a minimum warranty of 1 year.
If the DVR has technical problems or if you forget your device password, you can get assistance from the after-sales service. Unbranded DVRs do not have technical support, so stay tuned!
In general, products whose prices are far below the market should receive more attention. A good way to ensure product quality is to check if your DVR comes with a functional application.
If you want to check images anywhere, beware that it is not enough just to have this function. Remote Access works in 2 ways: Cameras can be accessed via DDNS or via P2P cloud.
There are DVRs prioritizing good-quality appliances, which are of better quality and have the security of remote access.
TYPE OF TECHNOLOGY
For systems with HD resolution and Full HD, there are AHD and HD-TVI technology options – but it’s important to remember that they are not compatible with each other.
So when buying a DVR and camera, make sure the technologies are similar and the system will work with the chosen configuration.
USE WITH A NOBREAK
The nobreak is a device that feeds through a battery, and the devices will connect to it when power off. So if your power fails, your monitoring system will continue to function normally. With this, the nobreak increases the life of your device.
Prioritize products with high resolution, because they are more cost effective than devices with old technology, for example, the devices with analog technology. For a good image quality, you’d better invest a little more.
