DVR Vs NVR Security Systems – Pros And Cons
A good security system does more than record evidence of a crime. Since criminals typically go for low hanging fruits when it comes to choosing targets, a good security system can act as an effective deterrent. As a result, it can protect you, or your place, from falling victim to a crime in the first place.
When you go shopping for a security system, you will generally have to choose between a DVR system and an NVR system. The difference between the two systems mainly lies in the way they do their recording and processing. While NVR systems use cameras that can both capture and process data, DVR systems rely on recorders to do the processing since the cameras that they use do not have the capacity to process raw footage on their own. As a result of this difference in approach, these systems tend to have their own pros and cons. Here is what you should know.
Quality of Output
The IP cameras that NVR systems usually have advanced technology that allows them to record both audio and video. The quality of images that these cameras record is of a higher quality and this allows these systems to be able to effectively identify details such as license plates and faces.
When compared to NVR systems, DVR systems offer lower quality images. Given the type of cameras that they employ, they are usually incapable of recording audio. This reduces the utility of the data that it records. With such a system, identifying details like license plates and faces can prove to be challenging especially if the recording is done under poor recording conditions.
Ease of Installation and Operation
Generally, DVR systems are simpler than NVR systems. This is because they use analog cameras that do not have complex technology. As a result, when it comes to setting up, they offer a simpler process when compared to NVR systems.
NVR systems on the other hand rely on IP cameras. These cameras typically feature advanced technologies. Given their advanced features, their software tends to feature an interface that is more advanced, and as such less user friendly. Therefore, when compared to DVR systems, they tend to be a little bit more challenging to set up and operate.
NVR systems generally offer better coverage than DVR systems. Areas that typically take multiple analog cameras to cover, can be covered by one IP camera. This is because the cameras that NVR systems employ come with multiple lenses. As a result, if you want a more minimalist set up that does not need multiple cameras in order to cover an area, going for an NVR system is advisable.
NVR systems allow for more flexibility in terms of ways in which they can be connected. With these systems, you can choose to make either wireless or wired connections. With DVR systems, you won’t have this freedom as these systems only allow for wired connections.
One area that DVR systems beat out NVR systems is affordability. If you are looking for a basic security system, going for a DVR system might make more sense especially if you have limited funds. And since NVR systems are more expensive, spending the extra money is only worth it if you care about the versatility, improved image quality, and overall flexibility in terms of connectivity, that the systems provide.
