The Differences Between Digital Video Recorders And Network Video Recorders
June 21st, 2019
When you decide to shop for a security system, you will have to decide if you wish to go with a Digital Video Recorder (DVR) or a Network Video Recorder (NVR). The major difference between the two recorders is how they process video data. It is important to understand that they also use different cameras, DVR is a wired system and NVR can be wired or wireless. In order to determine which of the two security recording systems is right for you, you’ll need to assess the pros and cons of each.
The Pros And Cons Of a DVR System
We have compiled a list of some of the pros and cons of the DVR system to help you with your decision making. There are two types of DVR units so we will address them both. The first one is a standalone DVR which looks like your home DVD player or an old VCR. It includes all power supplies and IC chips, DVR’s and CPU all in the unit. A PC-based look like a computer tower contains a LAN board, motherboard, and video card. It also has a DVD writer that allows you to burn your security video images.
Pros Of Stand Alone DVR
- Standalone DVR units have technology that has been proven for many years.
- Due to older technology and using an analog camera they are not as expensive
- They have an embedded software system that does not require daily updating
Pros of a PC-based DVR
- More flexibility: because they are PC based you can add and remove components like your own PC
- More user-friendly than standalone DVRs and have more features owners can interact with.
- Uses both analog and digital cameras.
- They have more power and greater memory so they can store more information.
Standalone DVR Cons
- They are not upgradeable. Everything is connected to one motherboard. If a component fails, you will probably have to replace the whole unit
- Limited storage capacity
- Does not integrate with other technology well
- Can only use analog cameras
Cons of A PC Based DVR
- More susceptible to security breaches, viruses, and hacking
- More expensive and require regular updating
- Bulkier and larger than stand-alone DVRs
- Susceptible to conflicts between the hardware and software due to the interchangeable parts.
Now having looked at the pros and cons of a DVR let's take a look at NVRs
The Pros And Cons Of An NVR System
An NVR uses a digital recording format burnt to a disc drive, USB drive, or a cloud-based system. NVRs are very advanced and can be a great option for both business and the home user. The pros and cons include:
Pros Of An NVR system
- Similar to DVR system pros
- Uses Wi-Fi connection
- Does not require professional installation
- NVR uses ethernet cables allowing them to communicate with each other.
The Cons Of An NVR system
- The signal is dependent on your internet connection. Weak internet connection will result in less clarity
- Cost is higher than DVR, but maintenance is lower
- Any signal loss will affect recording and surveillance results
- Not all IP systems are compatible with NVR systems
All of these options are an excellent choice. Which one you choose depends entirely on your unique security needs. A qualified security professional can help. They can assess your property, security needs, and existing security infrastructure to recommend which is right for you.
