Can You Use Different Brand Of Security Cameras With Different Dvr Reciver

Last Updated on three Feb 2022

When shopping for a security system, you'll need to choose between a DVR or NVR recorder. Whether you're a novice or a DIY security pro, you may observe yourself wondering what the differences are between NVR and DVR systems. What are CCTV and POE? Most chiefly, what is the right choice for your specific security needs? Both types of systems perform the same function, simply the difference is in how they do information technology equally well as the type of cameras used.

Agreement the divergence between DVR and NVR is essential when evaluating security systems. In this article, our security experts break downwardly the differences and detail the pros and cons of each and so that you lot can make an informed decision.

NVR vs. DVR – The Basics

At the cadre, both NVR and DVRs are responsible for video recording. DVR stands for Digital Video Recorder, whereas NVR stands for Network Video Recorder. The departure between NVR and DVR is how they procedure video data. DVR systems process the video data at the recorder. Conversely, NVR systems encode and process the video information at the camera, then stream it to the NVR recorder which is used for storage and remote viewing.

As DVRs and NVRs handle the video data differently, they require unlike types of cameras. Most NVRs are used with IP, or internet protocol, cameras, while DVRs are used with analog cameras. It's important to note that a DVR based system is a wired security organisation, whereas NVR systems can be a wired or wireless organization.

DVR Security System – Pros & Cons

Advances in analog loftier definition inside the terminal five years have reduced the gap in resolution between the two systems. You'll probably notice that DVR based security systems are priced lower than NVR systems. The lower price point is an attractive advantage of DVR systems, simply what are the tradeoffs? To answer this, nosotros need to break down each of the components of a DVR arrangement.

Camera Type – Analog
The cameras used by a DVR arrangement must be analog security cameras, amend known every bit CCTV cameras. Most of the cost savings establish past using a DVR arrangement is due to the camera. While you can mix and lucifer cameras in your home security organization, there is less flexibility in the type of cameras you can employ with DVR systems.

In a DVR system, the analog cameras stream an analog betoken to the recorder, which then processes the images. The reward of this organisation is the reduced complexity required of the photographic camera when compared to an NVR system.

Cable – Coaxial BNC Cable
The camera connects to the DVR recorder via a coaxial BNC cable. Although the use of coaxial cable may not seem significant, it does have some limitations:

• As the coaxial cable doesn't provide power to the camera, there are really two cables included within 1 covering – a power and video cablevision. The cables separate each terminate to provide the dissever functions. As such, y'all'll demand to install your DVR recorder near a power outlet.
• The size and rigidity of coaxial cables tin make installation more challenging. The coaxial cable is wider in diameter than Ethernet cables used with NVR systems which tin can make it more hard to run cables in tight spaces. Coaxial cables also tend to be more rigid, compounding this problem.
• However, if your property has existing coaxial connections for a previous security system, you can use the aforementioned cable to connect your new system.
• Standard coax cables do non support audio. A variant that with an added RCA connectedness is needed simply even with these a DVR has a express number of audio input ports then only a small number of cameras can tape audio.
• The image quality on coaxial cable will begin to degrade after near 300ft/90m, which can limit the ability to which you will extend your security presence outward. Lower quality cable will effect in a indicate loss at shorter distances.

Recorder
DVR recorders rely on a hardware chipset known equally an AD encoder, which is responsible for processing the raw data streaming from the camera into legible video recordings. DVR systems besides have unlike requirements when it comes to the recorder. Specifically, in a DVR system, the user must connect every camera direct to the recorder. In comparison, an NVR system simply requires that each camera connects to the same network. Also, in a DVR system, the recorder doesn't provide power to the cameras. Each camera connectedness volition need a splitter that supplies power to enable cameras to office.

Organization Flexibility
DVR security systems are less flexible than their NVR counterparts in terms of camera type and mounting options. Whereas NVR based systems can integrate both wired and wireless security cameras, DVR systems tin can simply use wired security cameras. DVR systems also have less flexible mounting solutions, considering routing coaxial cable can be more hard in tight situations and a power outlet is required for each photographic camera.

Image & Audio Quality
Every bit we've discussed, in DVR systems the cameras transmit analog video via the coax cable directly to the recorder and images are processed at the recorder level. The analog point results in a lower quality prototype compared to NVR systems. Coaxial cables as well don't natively transmit an audio signal, and DVR recorders commonly take a limited number of audio input ports.

NVR Security System – Pros & Cons

NVR security camera systems incorporate the newest technology to provide an enhanced, feature-rich security organisation. Also known as POE security camera systems, NVR based systems are more than flexible and complex than DVR systems.

Camera Blazon – IP Camera
As NVR systems process the video data at the camera rather than on the recorder, the cameras in NVR systems are much more robust than their DVR counterparts. NVR systems use IP cameras which are standalone image capturing devices. IP cameras each have a chipset which is capable of processing the video data which is then transmitted to a recorder. Unlike analog cameras, IP cameras are typically all capable of recording and sending sound as well equally video. The more powerful hardware on IP cameras besides enables improved smart functionality and video analytics, such as facial recognition.

Cable – Ethernet
Like DVR systems, NVR systems connect the camera to the recorder. Notwithstanding, how they connect the camera to the recorder is entirely different. NVR systems use standard Ethernet cables, such every bit cat5e and cat6, to transmit data. Professional installers adopt ethernet cables due to the number of advantages compared to coaxial cables:

• Ethernet cable powers the photographic camera using Power over Ethernet (PoE), which ways your camera needs ane cable running to capture video, sound, and ability the photographic camera, thus eliminating the need for messy splitters similar a DVR system.
• Ethernet cable tends to be easier to route and stop because it is thinner and has a smaller connector assuasive for less drilling.
• Ethernet is cheaper than coaxial cable and much more readily available, making cable replacement or organization expansion more accessible and affordable. Many modernistic homes and businesses are being built wired for Ethernet, making installation even easier.
• An added advantage of Ethernet cable is that every camera on the system can transmit audio since Ethernet can send sound data natively.
• Cables do non need to run between every camera and the recorder. They need to be on the same wireless network. Installation is more than straightforward and cleaner every bit multiple cables aren't required.
• Despite a shorter max Ethernet cable length, 328ft or 100m, network switches can exist used to extend total distance without impacting image quality.

Recorder
Different a DVR system, the recorder in an NVR system doesn't procedure video data. That step is completed at the camera earlier it is transmitted. NVR recorders are only used for storing and viewing the footage.

System Flexibility
NVR systems are inherently more flexible considering security cameras don't necessarily accept to be physically connected directly to the recorder. Instead, IP cameras simply take to be on the same network. As such, you could feasibly accept cameras all over the world on the same network that connect to your NVR can and then be viewed equally a comprehensive organization.

Epitome & Audio Quality
As NVR recorders receive a pure digital bespeak from the cameras, video quality is better than compared to a DVR at the same resolution. In addition, equally Ethernet cables carry audio, all cameras with microphones could record audio to the NVR.

In Summary – DVR vs. NVR System

Both NVR and DVR systems record video information and are reliable. Although in the past the video quality of DVR systems lagged backside comparable NVR systems, today this gap is significantly lessened. The difference betwixt DVR and NVR security systems come down to the price, how the data is transmitted, and type of cameras involved. NVR systems tend to have ameliorate moving-picture show quality, likewise as easier installation, increased flexibility, and native back up for audio on every camera that has a microphone. Withal, NVR systems besides tend to be quite a bit more than expensive than comparable DVR systems, which is an important consideration for the budget witting consumer.

For people looking for a relatively straightforward security system, a DVR organization will most probable be sufficient, specially if your property is already wired for a coaxial cable from an existing security system. If you demand a top of the line, very flexible solution, an NVR based system may be the best pick. At the finish of the day, the deciding factor will exist based on the specific security needs of your property.
