No Video Output

H-series Recorders are set to auto detect the output its connected to. So either HDMI or VGA. It also tries to auto detect the resolution of display your Monitor supports.

Sometimes this doesn’t always work and your monitor is stuck showing No Signal.

Step 1. Log Into NVR’s Web Interface

You will need the NVR and a PC connected to the same local network to access this.

Once logged in, go into the Configuration Tab at the top, then System -> System Settings -> Menu Output.

In our example, this NVR is connected to a 1080p monitor using the HDMI output.

As you can see, the NVR is output a really low resolution since it cannot auto detect.


In our case, we will change the Menu Output to HDMI/VGA and the Resolution to 1920/1080/60HZ.

Then Click Save.

The NVR will then Reboot.


After the NVR has rebooted, it should start displaying properly on your monitor once the corrected adjustments have been made!

Resetting an H-series NVR / DVR Password


Its very rare, but some recorders have an actual reset button physically on their motherboard. If you press and hold this for 30 seconds, this will default the recorder entirely. And you will start from scratch.

If there is no reset button, follow the next instructions:

Step 1. Download and Run the SADP Tool

You can Download the SADP Tool Here

Step 2. Determine the Firmware Version and Build Date

Example: 190703 = July 3rd, 2019

If the build date is 2016 or older, please email the full serial number of the recorder and email it to our support team.
If the build date is 2017 and newer, please go to the “2017 and Newer” Section below.

2016 and Older Instructions

Serial Number Location:

The Support Team will then send over a generated Key for you to use. (the code is good for that day only)

Click on “forgot password” in the bottom right corner  mceclip2.png


Paste in the generated code, input your new password then click Confirm  mceclip5.png


After Confirming, you should get a Success message and you’ll be all set!


 2017 and Newer Firmware

Select the device, by checking the checkbox to its left, and press the Forgot Password option on the bottom-right corner of the user interface.


A pop-up window containing instructions will appear.


Press the EXPORT button to export the password reset key.


After pressing the EXPORT button, a new SELECT FOLDER window will appear. For ease of use, select DESKTOP as the export directory and click on the Select Folder button on the bottom.


After locating the reset file on the desktop, email it to

Please allow an hour to receive a reply during normal business hours (Mon-Fri 9AM-5PM CST). If the email was sent outside of normal business hours, the reply will be sent on the next business day.

The reply from the technical support team will contain a reset file or key, generally called ENCRYPT (the file may have an altered name, if files for multiple devices are being sent). Upon receiving the reset file download it to the DESKTOP (for ease of access).

Please note, the reset file is good for 4 calendar days, and during those days the device for which the reset file has been generated cannot be rebooted or powered down.

To finalize the reset procedure, the Reset file or Key will need to be “imported” into the device, along with a new password (remember, there is no default password to reset to).


To “import” the reset file, click on the button with a FOLDER ICON.


A new OPEN window will appear. Select DESKTOP as an import directory and select the reset file and click on the OPEN button.


Type the new password into the NEW PASSWORD field, then confirms the password by re-typing the password into the CONFIRM PASSWORD field. Press CONFIRM.

After Confirming, you’ll get a Success Message and you’ll be all set!

Adding & adjusting H-series NVR with iVMS-4200

List of needed materials:

  1. Computer
  2. Recorder
  3. iVMS-4200
  4. SADP

You can download iVMS-4200 and SADP from the links below.


iVMS-4200 –

Once you have downloaded the iVMS-4200 software you can go ahead and start installing it. Once you get to the screen below if you have our H-series LPR camera. You will want to check the Data Retrieval and Statistics. Otherwise just click install.


Once you get to this page you are creating a username and password for the iVMS-4200 software. I would suggest making it the same as the username and password to the NVR. If you do not want to log into the software every time that you start it just check the Auto-Login box then click login.


Once you have logged into the iVMS-4200 software there are two tabs that you will be using the most. That is the Device Management tab and the Main View tab. Once you click on one name it will take you to that tab. Then just click on the 4 boxes in the upper left hand corner to go back to the control panel and select the other tab.


Then we will want to go the the Maintenance and Management tab and click the add button. Which will bring up the add section shown below. We will input all of the information for our NVR or camera here. We will select our adding method which will be IP/Domain if you will always be on loaction with the cameras and connected to the same network that they are on. Or you can select Cloud P2P if you are trying to view them remotely. We have a more in-depth guide on the Cloud P2P method linked below.


If you have trouble finding any of your H-series devices on our network. You will want to run the SADP tool to be able to find them. This will give you all of the information to be able to add the H-series device into the iVMS-4200 software.


You can manage the settings for your NVR or camera once you have it added to the software. To do this you simply click on the cog symbol under the operations section. If you do not see the cog symbol either minimize one of the other fields. Like serial number or use the scroll bar at the bottom of the Maintenance and Management tab to scroll to the right.


Once you click on the cog symbol you will see the window shown below. This window will give you about the same level of control as being logged directly into your device.


How To Set Up DDNS Account On NO-IP

If you are trying to view your NVR somewhere other than your home network , such as your place of business or a friend’s house, you will need to forward the ports on your router or you will get ‘page not found’ errors and messages.  Please refer to the “Port Forwarding” section of our Quickstart guides for information on where to find what ports your device is using.

You will then need access to your router. The procedure will vary depending on the make and mode, please refer to the owner’s manual of your router for information on how to forward the correct ports. You need to complete that step before starting the process below or DDNS will not work.


  1.  Go to and click Sign Up on the right-hand corner. noip.png
  2. Next you will be taken to signup page, fill out all the required information. You will enter your email, desired username and password and click “Create My Free Account“.  Also below the password field you will see your username that will be used to create your DDNS domain (free). You can select a few domains from the drop down list i.e, etc. noip2.png
  3. Once you have all the required information filled out click “Create My Free Account“.  After clicking that you will receive an email where you will be asked to confirm your account. As shown below click “Confirm Account” button. noip3.png
  4. You should now have a verified account created and should be logged into the NO-IP website. On top of the web page you will see “My Account“.   Click on that to access your Account Dashboard. Here is where you can create a custom host name by typing it in the “Host Name” box under the QuickAdd section or use the default one created whenever you signed up for the account. For guide purposes, we’ll use the default which will be your username and the extension you chose. In our example, we chose noip5.png noip6_001.png
  5. As shown in the image below the domain was created by default. In most cases it will be your  Click Dynamic DNS on the left side panel to see your registered domain. noip7.png noip8.png

NOTE: You will receive an email once a month from NO-IP to click on a link to keep your account active.


How to Set up DDNS on the NVR

  1. By now you should have the DDNS domain setup. Log into your NVR using a web browser (Internet Explorer preferred) and click the Configuration tab (as shown below). noip9.png
  2. On the left side of the page click Network>Basic Settings. noip10.png
  3. As shown below we need to ensure that the DNS server addresses are correct. If they are different from what is shown below, change them to the following (do not forget to click SAVE). noip11.png
  4. Click on DDNS tab on the page.  Here you will input your DDNS account information as well as the Domain.  Click the “Enable DDNS” so you can edit the fields. noip12.png
  • Select NO-IP for DDNS type from the drop down list.
  • Server address for NO-IP will always be
  • The Domain section will always be the same as the Domain that was made in step 4.
  • Username and Password will be the same as your no-ip website login.
  • Do not forget to click SAVE. noip13.png

NOTE: If the status shows anything other than what is shown below, check your log in information and all the other fields to verify everything is correct.noip14.png


Open a web browser (IE or Firefox) and type in your DDNS web address, you should be able to see the log in screen of the web interface. If you are using any other port besides 80 on the NVR enter that port number with a colon at the end of web address.

Example:   noip15.png

If you are still not able to pull up your DDNS name, it might be due to your ISP (Internet Service Provider). Some ISPs don’t allow a ‘loop through’ meaning you can’t pull up your public IP address while connected to your home network no matter what you try. If this is the case try connecting from an outside connection such as a friend’s house, your place of business, or a mobile device with the WiFi turned off.

Adding a camera on a TVI DVR to an H-Series NVR using the web interface

This guide will show you how to easily add a camera channel from an H-Series TVI DVR to an available channel on an H-Series NVR.


  1. H-Series DVR with a camera connected
  2. H-Series NVR with an unoccupied channel
  3. Computer


Before you begin you will need to get the IP address of the NVR, DVR and the camera number you want to add to the NVR (Ex. Camera 1, 2, 3, 4, etc).  You can find the IP address of both recorders by installing and running the SADP Tool.  In the example below we’ll be adding channel 1 from the DVR to the NVR.


1Access the web interface of the NVR by typing it’s IP address into a browser.   After logging in click Configuration at the top, then go to System->Camera Management->IP Camera Tab.



2. Once on the camera management page you will see a list of channel numbers (D1, D2, D3, etc) and their corresponding IP addresses.  Select the unused channel you want to use by clicking on it.  Next click the Modify button at the top.  On the window that comes up change it from “Plug and Play” to “Manual”.



3Fill in each field on the window as listed below:

IP Camera Address: Your DVR IP address

Protocol: IPCAM or Hikvision

Management Port: 8000 (Unless the server port was changed on the DVR, if so use that instead)

Channel No.: The channel number you want to pull from the DVR.  For example, if you want to add camera 2 from the DVR then input the number 2.

User name: admin

Password: Password to log into your DVR

Confirm: Password to log into your DVR

Transfer Protocol: Auto

Adding Method: Manual

4. Lastly, click OK.  You should see the status change to “Offline(Connecting)“.   After a few seconds Refresh the page (F5 on the keyboard).  The status should now say “Online“.

To confirm it added successfully go back to Live View and click the camera icon on the left.  You should now have a live view of the camera added to the DVR on your NVR.


This guide explained adding the camera assuming both the DVR and NVR are on the same Local Area Network (LAN).  If the DVR and NVR are at different locations this method will still work but requires the DVR server port (usually 8000) to be port forwarded.  After that’s done replace the IP address with the Public IP address of the location with the DVR.  Pulling in a camera from a remote location can consume a lot of bandwidth so it’s highly recommended to not do this unless there’s an above average upload speed at the DVR location (10mbps+).
