So, you’re looking to find the right security systems for your home or business. As you start to investigate cameras and proper video recording systems, two main types are going to pop up for you: NVR (Network Video Recorder) and DVR (Digital Video Recorder). Whilst both are responsible for video recording and ultimately can record footage onto a hard drive, they differ in how they are designed, set up, how they process data, and what they have to offer. Continue reading our beginner’s guide to learn more about these systems and which one might better suit your needs.
This blog details the basics of both NVR and DVR recording systems, explaining how they function and what the benefits are of each. If you’re looking for personalised security advice, reach out to Dorani today to speak with an expert.
What is a DVR Recorder?
The design of the DVR recording system is built to allow for video recordings in a digital format. There are a few major perks to choosing a DVR security system, including less money being required to set up a functioning, high-quality system, but let’s first dive into some of the key components required for DVR recordings.
Known better as CCTV cameras, analog cameras are the fundamental part of a DVR recording system – and this is where much of the cost is saved. DVR systems mightn’t allow for much flexibility in the type of cameras that can be used, but the reduced complexity of working an analog camera can make running your security system far more manageable. In a DVR system, the recorder processes the images streamed through an analog system from the cameras. Simple as that!
Coaxial cables connect the analog camera to the DVR recording system. The limitations of coaxial cables leave some people feeling as though they can’t be that essential to the system, however DVR data is required to be transferred over this specific type of cable. Common difficulties people find with coaxial cables are that they cannot support power supplying devices on the same line, and therefore another cable is necessary in order to carry electrical signals while the other carries data signals for any video transmission. Likewise, these cables can be tricky to install, and audio may not be supported by the standard coaxial cable.
Ad Encoders are vital to the DVR recording system. These are responsible for processing all raw data streaming from the camera into viewable, usable video footage. It is therefore important that every camera in this system is connected to both the recorder and a power source.
So, what makes people choose a DVR security system? Most commonly, it’s because of the price. A DVR recording system is the overall cheaper option in comparison to the NVR. If you aren’t looking to invest an exorbitant amount of money into your camera system, then the DVR may be the way to go – especially for small or domestic applications, which don’t encompass remote viewing or long-distance data transfer.
Some other key benefits that commonly make the DVR so appealing for prospective buyers include its minimal bandwidth usage. It’s a system that doesn’t demand a high amount of usage, driving down long-term prices and ensuring that your system will be able to last you a long while. On top of that, DVR systems are known for their signal stability, making them a reliable and cost-effective option.
What is an NVR Recorder?
As a network attached security system, an NVR recorder includes a software program that stores digital video recording to disk drives, SD memory cards, flash drives, and many other storage devices. Here are the essential components of an NVR recording system:
An NVR security system uses IP cameras. These are standalone image capturing devices, capable of processing video data before it is sent to the recorder for storage. IP cameras have the capacity to record and transmit audio as well as images, which makes them an appealing alternative to analog cameras. Advancement in technology has made IP cameras capable of video analytics such as facial recognition, and even picking up license plates.
Ethernet cables are accessible, cheap, and easy to work with. The thin structure of standard Ethernet cables makes setup a breeze, and you’ll find that an affordable cable is readily available in most stores. Standard cables such as the Cat5e and Cat6 work effectively to connect the camera to the recorder itself.
The NVR recorder is designed for storage and viewing of footage. It does not, however, work to actually process the video data into viewable footage.
There are several advantages to choosing an NVR system. While they may be more expensive, many people find that the perks outweigh the higher price point. Easier to install, the flexibility of these systems makes them simpler to work with. You can adapt more types of cameras and specifics of the system to suit your home, business, or property. Likewise, the NVR recording system offers better image quality, making your security system generally more effective.
