Let’s say the XVR recorder is somewhere between the DVR and NVR. It combines the functions of both of these types of CCTV recorders.
A digital video recorder (DVR) is a device used to process and record analogue HD CCTV cameras called HD coaxial cameras, which include HD-TVI, HD-CVI, and AHD cameras. NVR (Network Video Recorder) is a device used for IP security cameras.
Meanwhile, the XVR is a device capable of handling and recording both HD over coax and IP security cameras. In other words, the XVR recorder is a hybrid of a DVR and an NVR.
NVR is still the best choice for most installations or projects that use all IP cameras, but XVRs can come in handy if you need to upgrade existing security cameras and add more analogue HD cameras or IP cameras.
The main difference between XVR and DVR is that most XVRs can support all common CCTV video formats such as classic analogue cameras, TVI, CVI, AHD, and IP cameras with different resolutions like 2MP or 4MP (depending on the model and characteristics of XVR). This makes the XRV compatible with the vast majority of CCTV cameras regardless of the manufacturer.
XVR vs. DVR: Which Video Surveillance Solution is Better?
XVR Vs. DVR – The DVR usually supports certain types of video formats such as CVBS and TVI or CVBS and CVI, while the newer XVR models support all well-known CCTV video formats such as CVBS, TVI, CVI, AHD, and a range of IP cameras.
However, some common DVR models support all video formats except IP cameras. Technically, such voice recorders are called hybrid and tribrid. However, the main difference between XVR and DVR is to support an IP camera as well, it is called penta-brid.
Regarding prices, DVR and XVR recorders have almost the same prices, which are relatively cheap and depend on the number of channels. We recommend using XVRs as they provide a lot of flexibility. If you want to add an IP camera, you simply buy, install, and add it to the XVR over the network.
Uncovering the Pros and Cons: XVR Vs DVR
Installation flexibility
XVR Vs. DVR – Suppose you are installing a CCTV system and your client uses old analog or HD cameras. In that case, deploying XVR will provide more options without having to replace existing devices.
Let’s say a construction site system consists of an 8-channel DVR and 8 HD 1080p cameras, and we assume that you need to add a dedicated high-definition IP camera. If you have a DVR, you cannot do this, or you need to replace the recorder, which increases the cost. If you are using an XVR recorder, you can easily add an IP camera over the network and it will be supported by the recorder.
In addition, your clients may be frightened if you offer them to change the registrar and cameras, it will be too expensive for them. Just specify the XVR recorder, you can use existing cameras and add any other special cameras like narrow IP cameras or even HD high definition over coax cameras.
System of the Future
XVR Vs. DVR – What’s more, if you are an installer, you can earn the customer’s trust by offering XVR as it supports all HD over coaxial cameras, including IP cameras. Let’s be honest in saying that IP cameras sound better for the layman than the coaxial camera offering.
Reduces the cost of installing video surveillance
XVR Vs. DVR – With an XVR recorder, you can offer more at an affordable price. This is because you can mix existing cameras, add additional HD cameras over coax, which are still cheap, and add any IP cameras you need.
A video surveillance system becomes relatively expensive if you use an NVR and all IP cameras, and this can scare your customers away. In general, the XVR video surveillance system is cheaper compared to an NVR and at almost the same price as a DVR system (plus flexibility). After connecting the monitor, the user will be able to watch the processed video file. The information can also be viewed via a remote communication channel.
The recorder is used for video surveillance at the following facilities:
- Private houses
- Offices
- The shops
- Parking
- Checkpoint
- Gas station
- Industrial enterprises, etc.
What is the DVR Recorder?
The main components of the DVR Recorder include a processor, analogue-to-digital converter, control board, and other components. The device is controlled using the operating system.
There are the following types of DVR cameras:
- Network video recorder designed to work with IP video cameras.
- Hybrid recorder (compatible with analogue and digital cameras).
- Video recorder based on a personal computer.
- Recorders are used only for working with analogue cameras.
- A recording device designed for installation on vehicles (cars, boats, etc.).
Modern DVRs can be connected to computer networks. Devices for video recording are characterized by the number of input channels, resolution, type of compression used, and other parameters. The DVR Recorder can be connected to IP cameras and various external peripherals.
DVRs Manufacturers
We all know what video surveillance is. It is a camera that is installed in various places to monitor activities taking place in a particular area. However, CCTV is part of a larger system that is visible to people outside.
Various parts are hidden from the public, to which the entire video surveillance system of a particular place is connected.
If we think about it, this is a logical answer, but still, most people do not realize it. One of them is the display screen, which shows a live stream of cameras, and this is something that most people are aware of again.
The elusive parts that most people don’t see are called CCTV DVRs. They do exactly what the name suggests. They allow you to record actions captured on cameras.
While both are essentially involved in the recording, the procedure is very different. Below are the differences between XVR and DVR:
Digital Video Recorder (DVR)
They are used with analogue cameras. This is the main area of cost savings in this system. DVR Recorder systems transmit the signal to the recorder, where the images are processed.
The cost of DVR systems is lower than that of NVR systems due to the outdated technology. Also, the type of cameras that can be used is smaller than NVR.
They use BNC coaxial cable, which is old technology again and does not provide power to the camera at the same time.
Therefore, 2 wires are required to start the system. In addition, the cables are thick and not flexible, which also creates other problems. At longer ranges, the coaxial cable signal begins to degrade, which affects the image quality.
Video monitoring has been working in the UK for many years. It is especially readily used in public places: offices, shops, supermarkets, or companies.
It allows you to check what is happening in the surveillance area. In addition, it can warn of fire or unauthorized access. It is enough just to interface with the fire system and access control systems.
The IP camera works based on the Internet Protocol (IP). It looks just like a regular webcam that connects to a computer via a USB port. The differences between them, however, are very large.
The IP camera provides a live broadcast to the network so that its recording can be viewed through a browser.
The corresponding page can be found at the special internet address assigned to the camera. Thus, it is possible to control the observation area both from a computer and using mobile devices: a smartphone, or a tablet.
IP cameras are primarily used to monitor places and protect against burglary, theft, fire, flooding, or other threats that need to be quickly responded to.
Cameras of this type are used in offices, banks, firms, schools, and urban areas like parking lots, railway crossings, or intersections.
They enable you to watch live what is happening in a given place and to react quickly (for example, calling for security guards or technical personnel). They also allow the subsequent use of the stored records as evidence.
Cameras are also increasingly being installed in private homes. You can control the surroundings of your home (for example, a car in a parking lot or a garage, a gate at the entrance to a courtyard, or outbuildings), as well as an interior.
You will be able to make sure that your child is back from school and is doing their homework instead of sitting in front of the computer.
How to choose an IP camera?
Check what characteristics of the IP camera determine its functionality. The Angle of view – this determines how much area the webcam can “cover with a look”.
Resolution – it is determined primarily by the purpose of the camera. If face identification or reading of a car license plate is required, then the camera must have a high resolution.
The light sensitivity of the lens or additional external lighting (for example, using IR LEDs) is very important when recording an image in a dimly lit place or at night.
Built-in motion sensor, intelligent motion detection – this way the image is recorded only when needed. In addition, you send an email notification when a motion is detected, in which you will receive a photo from surveillance cameras. Here are other significant specifications of an IP camera.
Choose IP Camera
Method of connecting to the network – in the case of Wi-Fi, it is good if it is in the higher standard 802.11n or 802.11ac. Connecting the camera to the network using an Ethernet cable also works well. It gives you the confidence to have a stable connection and support high image resolutions.
Recording capability – you can choose different storage media: memory cards or NAS network drives.
The ability to connect additional sensors and alarm devices – expands the camera’s functionality. Thanks to this, a signal will be triggered if necessary, which will scare away the uninvited guest.
Possibility of remote control of the lens, which is very convenient when you need to see the area of observation you are interested in at the moment.
The built-in microphone and speaker is a very useful option that allows two-way communication. You can see what is happening and you can react: calm the dog down, say “Good night” to your child when he is under the supervision of someone else, or warn your grandfather about the danger.
Resistance to harsh weather conditions is a very important issue if you are looking for cameras for outdoor use.
XVR Vs DVR: Making the Right Choice
XVR Vs. DVR – In this article, we talked about the XVR and explained what kind of device it is. In a nutshell, it is a hybrid DVR Recorder / NVR offering more installation flexibility and a lower cost.
Using XVR will save you from the restrictions on the parameters of the CCTV camera in the future. Whether you are an end-user or installing it for a customer, you can rest assured that your video surveillance system can be easily scaled up for future expansions.
The abbreviation DVR Recorder stands for Digital Video Recorder. This device is used to record, store, and playback colour and monochrome video streams. DVR cameras are used in stationary and mobile video surveillance systems which is the primary difference between XVR and DVR.
The signal is transmitted to the recorder via cables connected to cameras. The received data is converted into graphic information, which is compressed using a special algorithm. Further, the video stream is recorded on a digital medium.
