Compared with NVR, DVR seems to be an old-fashioned technology. But it still has its own advantages and keeps some dedicated users.
The advantages of DVR system:
1. to save money.
Price is always an important factor, especially in the camera system. Generally speaking, the price of DVR security system is lower than NVR, because the analog camera is easier to produce, with fewer functions and lower resolution.
2. more stable signals.
The biggest advantage of DVR security system is that it can work on its own. That is to say, no matter how your network is, the DVR system will not be interrupted, just like the PoE NVR camera system.HD Car DVR wholesales china
The shortcomings of the DVR system:
1. need a lot of wiring work.
First, each camera will have a separate cable to deal with. In order to recover all the wires from different locations, you are likely to encounter some embarrassing situations, such as drilling holes on the wall or monitoring the cable range beyond the camera.
2. low-quality video.
Although the new technology greatly improves the recording quality of the analog camera (up to the highest resolution of 1080p), it still can't catch up with the NVR camera.
3. equipment needs closer.
The camera can be placed at a distance of DVR no more than 1000 feet so that the signal can be rapidly attenuated by coaxial cable.car monitor wholesales china
4. higher maintenance costs.
As I mentioned, DVR systems transmit signals through coaxial cables, which are more susceptible to harsh environments such as rain or strong winds. If they are exposed outside, you will probably pay extra bills when correcting cable problems.
5. many potential problems need to be dealt with.
DVR system does not mean that it is out of date, but it is not futurism. It will reduce market share every year.
This will lead to many potential problems that you may never have thought of. For example, some new homeowners will find a coaxial cable without pre - supporting DVR systems, and when it is true, you may even find it difficult to get local DVR maintenance personnel in the future.HD Vehicle DVR with 4g gps
