What Is DVR PCB?
A DVR PCB is the bare board on which the layout data for a digital video recorder (DVR) circuitry is printed.
The board is used to mount the components of the DVR once they have been secured.
The DVR PCB supports mechanically and connects electrically the components that make the DVR.
Conductive pathways etched from copper or other metals laminated onto a conductive substrate are used to make the electrical connections.
Which Is The Best Between DVR PCB Device Vs. XVR PCB Device?
Some DVR PCBs only support single formats such as TVI or AHD. There are, however, hybrid DVR PCBs that can support more than one format and accept various cameras using different formats at once.
XVR PCBs are more advanced as compared to the DVR PCBs. Actually, the XVR PCBs are advanced versions of the DVRs
XVR PCBs will accept all the HD over COAX formats and support IP cameras at the same time. That makes XVR PCBs more flexible and are therefore better than their DVR counterparts.
What Is The Difference Between DVR PCB And NVR PCB?
Let’s make this simple for you to understand:
DVR PCBs provide what can generally be referred to as D1 resolution. D1 resolution is the quality of video that has traditionally been used in close-circuit television systems (CCTVs).
D1 is the equivalent of 720 x 480 pixels resolution which is regarded a standard resolution that can be recorded and plaid back. NVR PCBs, on the other hand, can record footages in 1080 pixels which is high definition.
NVR PCB video quality is remarkably improved as compared to the DVR PCB. The video images are cleaner and clearer.
NVR PCBs accept IP cameras, a feature that gives them an edge over the traditional DVR PCBs. The IP cameras capture high quality videos and encode them before sending to the NVR over the internet for storage.
NVR PCB system of cameras and internet is easier to enhance than the DVR systems.
NVR PCBs also support wireless cameras so hardwiring can be omitted unlike in DVR systems.
The NVR PCB setup has the IP cameras encode videos before sending to the NVR for storage. In the DVR system, the videos are encoded at the DVR level, not at the cameras.
The DVR PCBs are also limited by the number of cameras and the length of the wire from the cameras to the DVR.
NVR PCB set up, being wireless, can have cameras set up anywhere and use programs to communicate with the cameras over the internet.
DVR PCBs are limited by the number of cameras and they must be physically connected to the cameras using cables.
The DVR PCBs come with a specific number of camera possibilities. They may be 4-channel, 8-channel, or 16-channel capability DVR PCBs.
8-CH Ahd DVR PCB Assembly
Once you have all the BNC points occupied in DVR PCBs, the only way to add new cameras is buying a new DVR.
So expanding such a system is very difficult.
Since the cameras are to be hardwired in a DVR PCB set up, the cameras must not be more than 500 feet away.
Long distances of the camera from the DVR leads to poor video quality and you may have to buy a video amplifier.
DVR PCBs don’t support power over same cable connecting the cameras like in NVR set-up that supports Power over Ethernet (PoE).
They need a separate power supply equipment to be installed leading to more costs.
One of the notable disadvantages of NVR PCBs is that not all IP cameras can be accepted by your NVR.
So you need to find out if a camera is compatible with your DVR kit before committing to buy it.
The other downside with NVR PCBs is that some NVRs might not have PoE ports built into them.
What Are The Features Of Common DVR PCB?
Some of the most common features of DVR PCBs are:
- Adapts MPEG-4 video compression
- Has a one channel resolution of up to D1(704*576)
- The video format is MPEG-4/ASF.
- MP3 audio format

- In-built RS232 series port for connecting external remote, keyboard, and for software setup.
Which Are The Types Of DVR PCB Assembly Systems Available?
DVRs come in various sizes from small pocket-sized ones to large computer sized ones. The three main types of DVR systems are:
Embedded DVR PCB System
These are independent devices that record and store compressed videos from analog CCTV cameras in a local HDD.
The operating system and the software are stored in the PCB chip and it has with it a HDD for storing images.
The OS used in the embedded DVR PCB set-up is exclusive and not open to external networks. That makes them less susceptible to hacking, viruses, and other malicious attacks and are therefore very secure.
Hybrid DVR System
These are the DVR PCBs that accept videos from both analog CCTV cameras and IP network cameras.
They are a good way to migrate from analog surveillance system to IP-based surveillance system.
The hybrid system also allows mixed use of video cameras.
One can choose to use IP cameras in high-risk areas while the CCTV cameras can be used in less vulnerable areas.
PC Based DVR System
In this system, a PC-based DVR PCB is integrated in a personal computer.
The resultant system consists of a motherboard, a network card, a DVR capture card, a video board, and a memory device.
The advantage of this kind of set up is that you can expand the system by adding more hard disks drives to it.
What Are The Benefits Of Hybrid DVR PCB Systems?
Hybrid DVR PCBs have the advantage of being able to accept both analog CCTV cameras and network IP cameras.
That makes them versatile and suitable for those wishing to migrate from old analog system but don’t want to discard the old cameras.
A hybrid DVR PCB system can help you in your transition journey as you prepare for full IP-based system in the future.
Which Are The Main Components Of DVR PCB Assembly?
The main components of a DVR PCB assembly are:
- DC/DC converter
- AC/DC converter
- Input power protection (eFuse)
- Analog video output interface
- Digital media processor
- Audio interface
- Input user interface
- Output user interface
DVR PCB Components
How Does A DVR PCB System Work?
The DVR PCB system is made up of CCTV camera that are hardwired to the DVR PCB device.
Besides, the videos captured by the cameras are recorded by the DVR PCB device.
The DVR PCB device is essentially just a computer whose function is to record security videos in a hard disk.
Most of the security cameras in use capture analog images. The DVR then converts the analog images to digital versions and then stores them on hard drives after compression.
The DVR device can manage several cameras. You can view all the footages at once or one by one depending on how you prefer it.
What Are The Applications Of DVR PCB?
DVR PCBs are essentially just used to build DVRs for CCTV surveillance system.
The DVRs are used to store CCTV footages for later playback when necessary.
In media industry DVRs, and therefore DVR PCBs for that matter, can be used to record and save TV programs for later playback.
Which Are The Common Ports Found On DVR PCB Assembly?
Functions, availability, and appearance of ports vary in various DVR PCBs.
The following ports are the most common ones found in DVR PCBs:
Power/DC 12V Port
It is the port to which the male end of an adapter is connected to connect the DVR to a power source.
The other end of the adapter is connected to a wall outlet or to an uninterruptible power supply (UPS).
BNC Video Input
The ports are used to connect BNC cables to transfer video signals from BNC cameras to the DVR.
RCA or DIN cables can also be used to connect the cameras to the DVR using appropriate adapters.
Octopus BNC Video Input
Octopus BNC video input is used in some DVR PCB systems to connect several cameras to one port so as to save space on the DVR.
DVR PCBs that support octopus BNC video input come with octopus cable to connect the cameras to different DVR channels.
Octopus BNC video input ports and octopus cables are mostly available in 8 and 16-channel configurations.
DIN Video Input
These ports are used to connect CCTV cameras having DIN connectors to the DVR.
DIN cables are specific to manufactures such that you cannot use the cables from one manufacturer with cameras from another manufacturer.
DIN cables allow transmission of power, 2-way audio, and video between the camera and DVR.
You should act with caution when connecting DIN cameras to the DVR because aligning the pins incorrectly might damage them.
VGA Video Output
VGA video output ports are used to connect DVRs to computers or TV monitors using a VGA cable to view videos.
VGA cables transmit signals in analog form so the signals must be converted from digital forms used in DVRs and LCD monitors.
HDMI Video Output
They are used to connect DVR to high definition television sets or compatible monitors for CCTV footage viewing using HDMI cables.
They carry signals in digital form unlike VGA cables and conversion is therefore not required to analog form by LCD monitors or DVRs.
DVI Video Output
Here, a DVI cable is used to transfer videos from the DVR to a computer monitor for viewing.
The DVI also carries signals in digital form and does not therefore require conversion to analog form like in VGA.
A DVI-to-VGA connector can be used to connect a DVR with a DVI video output port to a monitor with only VGA inputs.
You cannot, however, connect a DVR with a VGA video output to the DVI input port of a monitor.
BNC Video Output
This port is used to connect the DVR to a CCTV monitor for footage viewing using a BNC cable.
BNC Spot Output Port
The port is used to connect a DVR to a spot out monitor with the aid of a BNC cable.
Do You Require An Application Software For DVR PCB Device?
Yes, you need a Video Management Software (VMS) to coordinate video recording system. A video management helps you to identify, isolate, and pull out the most critical moments of your video recordings.
There are several options for VMS available but the one you go for will depend on the DVR you have picked.
You should make sure the VMS you buy is compatible with your DVR PCB device and has got user friendly interphases.
You can have a separated solution where cameras are separated from the VMS or an integrated one where the two are blended.
A separate system allows you to retain old cameras in case you choose to upgrade though it presents challenges of compatibility and scalability.
Having an integrated hardware and software system saves you the hassles to do with compatibility issues because it comes ready to use.
The integrated solutions also come with frequent updates and new features which ultimately prove to be beneficial.
Another upside of integrated system is that it can also be integrated with other software management systems such as visitor management system.
Some of the Video Management Software solutions are:
- Cisco Meraki
- Blue Iris Software
- EyeLine Video Managemnt Software
- ContaCam Video Management Software
What Are The Video Compression Formats Of DVR PCB Assembly?
Video compression refers to the process of using a codec to scan through your video files while eliminating the unnecessary content.
Video compression makes your files smaller so that you can store more videos.
Most of the DVR PCB assemblies use H.264 codec to compress videos.
H.264 is known for recording videos of high quality while also economizing on space.
The other video compression format is Motion JPEG/M-JPEG standing for Joint Photographic Express Group.
Also available in the market is MPEG-4 (Moving Pictures Experts Group).
M-JPEG and MPEG-4 both came ahead of H.264. The three compression models (M-JPEG, MPEG-4, and H.264) can all record and display up to 30 FPS though they differ in certain areas.
Is DVR PCB Compatible With All Types Of Cameras?
No, there are cameras that may not be compatible with your DVR PCB system.
You should therefore be sure that a camera will be accepted by your DVR PCB before deciding to buy it.
Does DVR PCB System Supply Power To The Attached Cameras?
Unlike the NVR PCB system, DVR systems do not have the PoE feature.
They cannot transmit electric power required by cameras over the same cables for transmitting videos.
DVR PCB system must have an alternative power source for supplying the cameras.
What Is The Ideal Audio And Video Bit Rate Of DVR PCB?
Bit rates in DVR PCBs basically mean the quantity of data being used or sent in the DVR systems for a specific stream.
They are essentially a representation of video quality and are normally presented in numbers in kilobits per second (kbps.)
More data implies more quality though there must be limits.
There are, for example, bit rates such as 1028, 4096, and many more depicting quality.
Bit rates are adjustable and a user is expected to pick the value that suits their needs best.
That means there is no recommended ideal value for bit rates but only what will serve you best.
Users can pick the best bit rate value for them guided by the information available in the user’s guide configuration page.
The bit rate configuration section is mostly labelled Video/Audio something.
How Do You Connect Analog Cameras To DVR PCB Device?
Analog cameras are hard wired to the DVR PCB. A BNC coaxial cable is used to directly connect the analog cameras to the DVR PCB system.
More coaxial cables are required to connect more cameras to the DVR.
The cameras capture videos and then transmit to the DVR for encoding.
What Is The Recording Resolution Of DVR PCB Devices?
DVR PCB devices normally offer what is referred as D1 resolution.
D1 refers to the quality of video that has long been used in the closed-circuit television systems.
D1 is an equivalent of 720 x 480 pixels. It is regarded to be the standard resolution that can be recorded and plaid back on a screen.
Can DVR PCB Systems Connect To The Internet Like IP Cameras?
The DVR PCB systems cannot connect directly to the internet like the IP cameras.
Being part of the closed circuit system, connections are done locally and not through other external networks.
It is important to note, though, that hybrid DVR PCBs can accept videos from both analog and IP cameras. PC based DVR PCBs also have network cards in-built in them.
How Many Channels Can DVR PCB Assembly Support?
DVR PCBs mostly come in 4-channnel, 8-channel, or 16-channnel capabilities.
The number of channels refers to the number of cameras the DVR PCB can support.
A 4-channel DVR PCB will support 4 cameras, an 8-channel will support 8 cameras, and a 16-channel one will support 16 cameras.
4-CH DVR PCB
Why Is EMI Resistance An Important Consideration In DVR PCB?
Electromagnetic interference (EMI), refers to the disturbances coming from an external source that interferes with an electrical circuitry through electromagnetic induction.
EMI can degrade the performance of a DVR PCB system or even stop it from working.
To alleviate the undesired effects of EMI, it is important that measures to make DVR PCB EMI resistant are considered in design.
EMC shielding is one way to solve EMI problems.
EMC is the acronym for Electromagnetic Compatibility.
It means that a circuit has been designed to withstand the effects of electromagnetic fields by shielding.
EMC shielding in DVR PCB refers to measures taken to prevent external electromagnetic signals from interfering with its internal signals.
EMC shielding can also be viewed as preventing the DVR’s signals from leaking out to interfere other electronics.
What Is The Purpose Of ESD Protection In DVR PCB?
Just like with other electronics, accumulation of charges can damage components of your DVR PCB.
Electronics are sensitive to changes in voltage so it is imperative that you plan for ESD protection in your DVR PBC designs.
Electrostatic discharge (ESD) occurs when two objects bearing different charges come so close that they break down the medium between them into ions.
For consumer products such as DVR PCBs, ESD is normally experienced when the electric field between two points exceeds 40kV/cm.
Environmental elements such as humidity and air pressure will affect the electric field strength.
For instance, high humidity in a place may cause the air to be more conductive leading to higher chances of ESD.
Whichever way it is caused, ESD cause damages to your DVR PCB.
When voltage due to ESD is large enough, a conductive path for current will be created leading to enormous pulses of current.
Current pulses due to ESD in a PCB can lead to heat dissipation in the components and conductors of the PCB.
The components of the PCB can get damaged at extreme field strengths and excessive developed currents.
ESD protection circuits are implemented in DVR PCB circuits to prevent developed current from flowing to other parts of the PCB causing damage.
The protection system diverts the current to the ground through a low-reactance connection.
Can You Integrate Motion Sensors In DVR PCB Systems?
DVR security systems are customizable and can be modified to suit the needs of a user.
One of the items that can be integrated into the DVR PCB system is a motion sensor to bolster a user’s security requirements.
The DVR PCB system can be configured to perform various functions that one would want to achieve with the PIR motion sensor.
Most cameras, of course, already have motion sensors built in them.
One may, however, want to integrate the PIR sensors into their system because they are more sensitive to changes in environment.
The PIR sensors may also be preferred because they have a wider range of detection.
If you want to have sensors in your system, just install and configure them in your DVR PCB system.
When adding motion sensors into your DVR system you should consider how far they will be from the DVR.
Another factor to consider is how far they will be from the power source.
What Is The DVR PCB Cost In China?
DVR PCB cost in China varies from manufacturer to manufacturer. Generally, the price for building a DVR PCB is around $5.
Factors that determine the prices of the PCBs are size, the number of layers, board thickness, and the quantity ordered for.
Which Are The Important Specifications Of DVR PCB To Consider?
Some of the most important specifications to consider in your DVR PCB design are:
- Internationally recognized base materials should be used
- Solder masks should be defined in accordance to IPC-SM-840 class T
- Tolerance for copper clad laminate should be of acceptable standard
- Hole plating should be 1.25 micron nominal as per IPC class 3
- Cleanliness requirements such as those recommended by IPC should be observed.
- Required tolerance for holes, profile, and other mechanical features should be met
