How Does DVR PCB Work?

Analog cameras need to be installed in a DVR device for recording and archiving footage. DVR PCBs are designed to cope up with different security applications. Also, a DVR PCB is super flexible as it can be of any size required.

CCTV cameras are a part of the DVR PCB system. The manufacturer hardwires the cameras to the DVR PCB device. The camera records videos and the PCB device records them.

This PCB device is basically a computer device. The computer works to record and saves the security videos on a computer hard disk.

The security cameras in the DVR device capture analog pictures. The DVR system then transforms the analog pictures into their digital format. Then the digital images are compressed and saved on a hard drive.

A DVR device can have several cameras in its system. If you prefer to view the footage one by one, the device can do that. Or if you prefer to watch all the footage at once, the DVR system provides that opportunity as well.

Does DVR PCB Need Application Software?

DVR PCB system needs application software in its application. The kind of software a DVR PCB needs is VMS or Video Management Software. This software helps to coordinate the recording system of videos.

A video management software is able to isolate, identify, and pick the crucial moments of the video footage. You need to use the Video Management Software that goes with your DVR device. The VMS should also have a user-friendly interface.

There are both individual and integrated solutions for the application software. If the cameras are distinct from the VMS, you are allowed to have an individual solution. If both of them are attached and blended, you can use an integrated one.

Application Software Of DVR PCB

A separate system is able to retain old cameras if you want to upgrade them. But the disadvantage is that it throws obstacles of scalability and compatibility.

But an integrated system both in software and hardware has way fewer hassles to work with compatibility issues. The reason is that an integrated system comes as ready to use. There also come new features and frequent updates for an integrated system.

All these new features and updates are super beneficial for the DVR device. Another advantage of the integrated system is that it can be integrated with various other software management systems. To name a software management system, we can say visitor management system.

Video Compression Formats Of DVR PCB

Mostly H.264 codec is used in DVR device assemblies to compress the videos. H.264 is used most of the time because it is good for recording high-quality videos. It also helps in economizing on space.

Another commonly used video compression format is M-JPEG or Motion JPEG. It refers to the Joint Photographic Express Group. MPEG-4 means Moving Pictures Experts Group is another used video compressing format.

MPEG-4 and M-JPEG both came ahead of H.264. All these video compression formats are able to display and record up to 30 FPS. but all of them differ from each other in certain areas.

What Is The Perfect Video And Audio Bit Rate Of DVR PCB?

DVR PCB bit rate means the quantity of data that is being utilized in the DVR system for streaming specific content. They present basically the standard of the video. The unit for bit rate in DVR devices is kbps, that is kilobits per second.

If more data is used, that means better quality of the video. But there is a limitation of how much data can be transmitted. The most common bit rates are 1028, 4096, and some more illustrating quality.

You can adjust the bit rates of your DVR devices. By adjusting the bit rate, you can choose the appropriate rate for playing your video on your device. There is no recommended perfect bit rate value for your video or device.

You are supposed to choose your perfect bit rate value according to your preference. The bit rate of a DVR device is usually marked as the bit rate of audio and video.

Before deciding to buy a DVR device, you must make sure that it will accept your required camera. That will increase the device’s efficiency and will be cost-effective as well.

Here is a video of the camera controlling DVR devices.

Is There Any Way To Attach An Analog Camera To A DVR PCB Device?

Yes, analog cameras can be attached to DVR PCB devices. Generally, an analog camera is hard-wired to a DVR device. The manufacturer uses a BNC coaxial cable to attach the analog camera directly to the DVR system.

Camera In DVR PCB

If you prefer to joint more cameras to the DVR system, then you will need more coaxial cables. The cameras’ function is to capture the videos and then send them to the DVR. Further, the DVR encodes the videos.

How Does DVR PCB Provide Power To The Connected Camera?

DVR PCB is not able to supply power to the connected cameras. They do not contain the PoE feature like the NVR PCB systems. And so the DVR system is not able to transfer the electric power that the cameras need.

There are cables to share videos to the DVR device from the camera. But the cables are not capable of transmitting electric power to the connected cameras. The system should have another source of power to supply power to the cameras.

Watch the following video to get an idea about the power supply of DVR PCBs.

Is DVR PCB Able To Connect To The Internet?

The answer is no. DVR PCB is not able to connect to the internet directly. The internet could be like IP cameras.

Internet Connection In DVR PCB

DVR PCB system is a part of the closed-circuit system. That is the reason for DVR devices to use local connections to connect to the internet. They are not able to connect to the internet directly that is not through external networks.

Why Do You Consider EMI Resistance In DVR PCB?

EMI or Electromagnetic Interference means the disturbances that an external source causes and gets in the way of the electrical circuitry through electromagnetic induction. EMI is able to decrease the DVR system performance. It may even make the system stop functioning.

The manufacturer should make the DVR design EMI resistant. You should consider this fact while making the design layout to make the DVR PCB system efficient. These measures must be considered and taken care of to get a perfect DVR device.

EMI Resistance In DVR PCB

To get rid of EMI problems in your DVR device, EMC shielding can be one way. EMC is the abbreviation of Electromagnetic Compatibility. It refers to a circuit that is designed specifically to avoid electromagnetic fields’ effects by providing shields.

EMC shielding indicates measures that the manufacturer takes to resist external electromagnetic signals from getting in the way of its internal signals in the DVR device. You can also view the EMC shielding as resisting the signals of the DVR from getting out to interfere with other electronic devices. And so it is so important to consider EMI resistance in DVR PCB.

What Is The Importance Of Implanting ESD Protection System In DVR PCB?

The importance of ESD protection in DVR PCB is beyond description. And it is so important for some obvious reasons. ESD causes different kinds of damages to a DVR device so you must take protection for it.

Charges building up can damage your DVR PCB’s components just like with other components. We all know that electronics are sensitive to voltage changes. So for that reason, you take ESD protection in your DVR designs.

ESD or Electrostatic discharge happens when two objects of individual different charges get close to each other. Then the different charges break down the medium separating them into ions.

ESD Protection In DVR PCB

Consumer products like DVR PCBs, the ESD usually happens when the separating electric field between two charge points exceeds 40kV per cm. Different environmental conditions like air pressure, humidity, etc may affect the strength of the electric field.

For example, we can say if a place has very high humidity, it may be the reason for the air to be more conductive leading to more opportunities for ESD. In short, ESD causes damage to your DVR PCB. It doesn’t matter whichever way the ESD is caused.

ESD may raise the voltage of the DVR device to a very large extension. When the voltage caused by ESD is very high, the system creates a conductive path leading to large current pulses going through.

ESD can cause a large number of current pulses in a PCB device. This excess amount of current pulse can lead the system to heat expenditure in the PCB components. It can also cause a lot of heat dissipation in the conductors of the PCB.

As a result, the PCB components can get damaged for excessive developed current pulses through the system. The components also get damaged at extreme field strengths. To prevent these damages, we implant ESD protection in the DVR system.

The manufacturer implants ESD protection circuits in DVR device circuits to resist the developed current pulses from flowing to other parts of the PCB that cause several damages to it. What this protection system does is converting the developed current to the ground. The protection system does divert the current through a low-reactance connection.

Is DVR PCB Device Better Than XVR PCB Device?

To be honest, the XVR PCB device is better than the DVR PCB device. Actually, XVR PCBs are advanced versions of DVR PCBs. So the XVR one is the better one for obvious reasons.

Some DVR PCB devices are only capable of supporting single formats like AHD or TVI. There are hybrid DVRs that are able to support more than only one format. They can accept several cameras each with a different format at a time.

In this case, the XVR PCB is more functional compared to the DVR ones. The manufacturers increase the functionalities of DVR PCBs and then the form it takes, is known as XVR PCB. XVR PCB has more uses and advantages in several fields of applications.

XVR PCB is able to receive all sorts of HD over the COAX formats. At the same time, the PCB can attach IP cameras as well. These facts make the XVR PCB more versatile and flexible.

By this comparison, we can come to the point that XVR PCBs are better than DVR PCBs.

How Do You Choose The Right Manufacturer Of DVR PCB?
