The biggest reason as to why you need DVR is its reliability. If the internet goes down, you need to worry about your NVR working. This NVR setup isn’t ideal if you are concerned about stolen merchandise. You need your security system to work to protect your business.

You also don’t have to worry as much about finding compatible cameras to work with the DVR system. With NVR systems, not all IP cameras work with every model system. This setup isn’t an issue that you have to deal with when you have a DVR system.

How Does DVR Recorder Work?

The DVR works by saving security footage to its hard drive. When the camera captures the analog footage, the DVR converts it to digital.

Then, it compresses the footage to save it.

Several cameras can be hooked up to 1 DVR. Most systems come with 4, 8, 16, or 32 inputs for cameras. With DVR, you have the option to view all of the images at once or individually.

You save all footage to the DVR drive. You don’t need to purchase additional switches, multiplexors, or quads.

You can connect your DVR system to either analog cameras, AHD, or HD-TVI cameras. The DVR system can encode up to 720p resolution. The HDMI and VGA output can potentially reach up to 1080p resolution. There are many great features of the DVR, including:

Instant playback during the multi-channel live view mode for the assigned camera
Customization of tags
Playback using tags
Manual video quality diagnostics
Depending on the model of the DVR system, you can get the features that you need for your business. It’s true that DVR doesn’t have the same flexibility as the NVR systems. On the other hand, this DVR can be a better option if you run a smaller business.
