Internet Explorer Troubleshoot-“Signature is Corrupt or Invalid”
Description
If you see this warning (see the image below) when trying to download a plugin for a recorder or IP camera, this is your antivirus trying to block a our unsigned (i.e. WHQL) plugin. Installing this plugin will allow the camera’s feed to stream in IE.
Prerequisites
• PC with Internet Explorer installed
• Connection to remote camera or recorder
Step by Step Instructions
1. Clear your WebRec Folder by navigating to the program files/webrec folder and also program files(x86)/webrec folder and double clicking the uninstall icon to uninstall the plugin.
2. Once uninstalled open Internet Explorer and enter the IP address of your device into the URL area of the browser and hit enter. Log into the camera, or once prompted to download the plugin select the pull down menu button next to “Save”, now select “Save As”.
3. Navigate to your desktop so you can save the program and find it easily.
4. Now right click the program and select “Run as administrator” to install. You might need to reload the IE browser webpage once the plug-in or program has installed to get the video stream to work.
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.
System can not detect hard disk.
There are following possibilities:
• HDD is broken.
• HDD ribbon is damaged.
• HDD cable connection is loose.
• Main board SATA port is broken.
• HDD is not compatible.
• Insufficient power.
Solutions
• Reboot Device.
• Disconnect the hard drive from the device, then boot it up with the HDD disconnected. If there are no errors when booting without a hard drive, then the hard drive is most likely the problem and needs to be replaced.
• Format HDD.
• If you cannot format HDD from device, format HDD from a PC.
• Check HDD compatibility.
• Check HDD cables and if connections are secure.
• If SATA port is broken try another SATA port.
• Reset to device to factory settings.
• Make sure you have the correct power cable for the Device.
• Replace HDD.
• Open Casing and check jumper settings

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.
• Recorded file has been overwritten.
• File is in DAV format. Use Conversion Tool.
There are following possibilities:
• If HDD ribbon is damaged then replace ribbon or HDD.
• If HDD is broken then replace HDD.
• If Upgraded program is not compatible then find another program to upgrade.
• If the recorded file has been overwritten then there’s not much you can do unless you have backup.
• If Record function has been disabled then enable it.

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.

• 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.
