DVR NVR Troubleshooting All Manufacturers, DAHUA NVR TROUBLESHOOTING, Hello dear visitor, in this article we will present you the frequently encountered problems and solutions in DVR NVR and IP Camera security systems. We will explain it through the Dahua recorder, logically many systems are the same. Hikvision Dahua XMeye Uniview or other OEM systems generally work on the same logic.

P2P Troubleshoot

There are following possibilities:

• Check the network connections from NVR to your router.

• Check the device P2P function is enabled or not. (Main menu*>Setting*>Network*>P2P)

• Check cell phone P2P login information is correct. You will need to ensure the user name and password are correct. (This is the credentials for logging into the system.)

• Check P2P SN is right or not. You can use the cell phone to scan the QR code on the device P2P interface (Main menu*>Setting*>Network*>P2P), or you can use the version information of the WEB to confirm. (For some previous series products, the device SN is the main board SN, it may result in error.)

Step by Step Instructions

1. Check that, “P2P is enabled under, Main Menu->Setup->Network->P2P

2. Check that the P2P status is, “Online”

3. Enable DHCP under, Main Menu->Setup->Network

4. Reboot the NVR.

DDNS registration failed or can not access the device domain name.

DDNS (Dynamic DNS/DynDNS) is a method of automatically updating a name server in the Domain Name System (DNS), often in Not Real Time, with the active DDNS configuration of its configured hostnames, addresses or other information.

If DDNS is not working properly please try to:

1. Check the device to see if it is connected to the network:

2. Verify that the device has acquired and IP address via DHCP or that a static IP has been assigned.

3. Ensure that you can connect to the system on via the local network:

4. Try to access the system from another device on the network e.g. Try to open the web interface of the device from a web browser on your local network.

5. Check the corresponding protocol of the DDNS is enabled:

6. Log into the DVR/NVR/CVR and navigate to the “Network” menu then look for the DDNS option and check the box to enable the service. After the service is enabled you will need to fill in the required informwation i.e. DDNS Type, Host IP Port (1~65535) Domain Mode Domain Name and Email Address if applicable

7. Check the DDNS credentials at the DDNS site and menu of the system:

8. Please confirm that log in information matches on the Dynamic DNS platform that you are using and also in the DDNS section of the recorder.

9. Default Google DNS server is 8.8.8.8, 8.8.5.5.

10. Use different DNS provided by your ISP.

Motion detection function does not work

There are following possibilities:

1. Sensitivity is too low, or Threshold too high.

2. Most third-party cameras will not have the full capabilities, like motion detection, to work.

3. Check if firmware of Recorder and IP camera is current.

4. Ensure motion detect is enabled on each camera, applied and saved.

5.Period setup is not correct.

6. Motion detection region setup is not correct.

Here on the region settings you have a total of 4 regions you can set for each camera view. In each region you can set the sensitivity and threshold at different levels.

The regions are numbered reigion 1 – 4. Each numbered region has a corresponding color as follows:

Region 1 is red

Region 2 is yellow

Region 3 is blue

Region 4 is green

Here is an info-graphic explaining sensitivity and threshold:

7. Try defaulting camera settings.

8. If it is an IP Camera login in via web and try defaulting from there to see if defaulting fixes the issue.

9. Ensure enable and record is checked off applied and saved.

10. Ensure the schedule is set for motion recording.

Unable to Playback Recordings

• Check that HDD is detected by NVR.

• “Record Status” is set to, “Enabled” on all channels.

• Check, “Record Schedule” and ensure your desired recording is enabled; Motion, Schedule, or Alarm Recording.

Alarm signal can not be disarmed

• Alarm setup is not correct

• Alarm output has been open manually

• Input device error or connection is not correct

• First Factory default the system to try to clear it

1. To begin troubleshooting please reset all events by logging into your NVR/DVR/HCVR/Tribrid and going to Setup>System>Default and check only the event box and select default. This will clear all of your event data for all cameras connected on this NVR/DVR/HCVR/Tribrid and on the connected IP Cameras themselves. To be specific this feature will disable all Video Detect, IVS, Face Detect, Audio Detect options on the camera. If this fixes your alarm signal then your alarm setup on the camera was not setup correctly. Don’t forget that if you were using motion detect for recording you will need to re-enable these features.

2. If this didn’t fix the problem then you need to check the wiring on the back of your NVR/DVR/HCVR/Tribrid for your alarm input and output. Alarm inputs are set to NO (normally open) by default. In case you have a sensor that is open all the time, you might want to set the input to NC (normally closed). For an in-depth guide on how to wire and setup physical alarm inputs and outputs please visit:

How To Connect Electronic Buzzer Tutorial

3. If this didn’t fix the problem, perform a factory reset on your NVR/DVR/HCVR/Tribrid Recorder in Setup>System>Default, click factory reset, and then yes.

Alarm function is null

If you are experiencing a nonfunctional or non working alarm then you might want to consider that the alarm was setup incorrectly.

Resources for Alarm Systems

• Reset your event options: Unable to Disarm Alarm

• How the alarm functions are setup on an NVRHow to Connect Electronic Buzzer

Possible Problems:

Here are also some possible problems that may have occurred upon setup:

• Alarm is not setup correctly (event settings can be incorrect)

• Alarm cable connection is not correct (check your connections)

• The alarm input signal might not be correct, the alarm input supplies a low voltage (< 2.0 VDC). If you are supplying a voltage in excess of that to show a closed or open signal then you will need to wire a resistor into the circuit to get the proper voltage to the alarm input pin out.

• There are two loops connect to one alarm device, which will send a false signal or keep the circuit open (check your wiring).

• The protection zone that the intruder is entering has not been enabled (in the IVS rules setup, and IVS event) the arm function or the intruder has enough knowledge to disable the system. See Intrusion Detect for more details.

• The siren output device is incorrect on the back of the recorder and does have the warning function setup correctly. Make sure the siren wired into NO1 and C1 correspond with alarm out 1 when configuring your setup.

• If the detector (alarm input) is not working when there is an alarm outage, you might have wired your alarm input into your alarm output or input. (check your wiring)

• The detector (i.e. door sensor, PIR sensor) might not be in the proper position and can not detect the corresponding zone (reset the angle of the sensor)

• The recording system can not generate an alarm when there is something wrong with the alarm signal transmission system (the service is disabled, there is malicious attack and etc)

• The device is not working, resulting from non-schedule maintenance of the alarm system (has someone worked on the system recently?)

Please Be Advised

Sometimes it is best to call the engineer who setup your alarm system if you do not know what you are doing, as tampering with some systems can set off subsequent systems.

Step by Step Instructions

• If you are using a NVR:

1. Look at the order the cameras were added and keep track of the IP’s of the cameras you want to re-arrange.

2. Delete the cameras and add them in that specified order.

• If you are using a HCVR:

1. Keep track of what channels you want to switch. The recorder’s channels are assigned by the numbered BNC ports on the back of the unit. Labeling the channels might help when switching the ports around to the specific order you want.

2. Unplug the BNC connectors and move the correct camera to the correct channel.

• If you are using a Tribrid (HCVR) with HD-CVI/Analog and IP cameras:

• On the HCVR the BNC channels come first, then the IP channels (when allocated). To work around this the tour function must be used to rearrange the camera order.

1. The cameras are prioritized by the BNC ports for the first set of channels. If you want the IP channels to appear first you will need to setup a tour mode on only one tour setting. Open the menu on the NVR and select SYSTEM(under SETTING)->DISPLAY->TOUR

2. Check the Enable Tour box.

3. Make sure all of the Window Split Views (1,4,8,9,16) are left unchecked, otherwise this will initiate a tour of the checked views.

4. Now setup one tour under the grid view you want to look at, this demo is 16 views.

5. Select Add, and highlight the channels in the order you want to see them on the screen and click OK when finished.

6. Make sure the custom tour that was setup is checked and then enter 120s (or the maximum) on the Interval area.

7. Select apply
