A password has been set on a camera and neither the customer nor integrator knows it.

For best results see the below:

 Once a nonce file has been generateddo not do anything with the camera (i.e. power cycle it) until you are ready to apply the key files. If the camera was powered down before the reset code was applied then a new Noncefile will have to be generated and reapplied.
 Nonce files are valid for approximately 24 hours. If it does not work reach out to technical support.
 Directly connect to the camera with a PoE injector for the best results.
 Disable any firewall or security software on the workstation.
 Disable sub-interfaces on the Ethernet adapter
 JCI Specific: Disable the Cisco AnyConnect Security Mobility Client and the virtual Ethernet (Default Switch) adapters.
 We have encountered issues resetting passwords over Ubiquiti Wireless networks. If a password reset fails, connect directly to the same physical switch as the camera.
 For Verint Systems, remove the camera from the VMS then attempt a password reset. Password resets performed while connected to a Verint system have failed.
 If the camera saysInaccessibleyour workstation is not in the same network range as the camera. Change the workstation to match the camera. Relaunch AV IP Utility and it should say “Pwd Protected.”

How to reset passwords on AV Costar Cameras

AV IP Utility / Costar Utility cannot discover a camera


Cameras are not being discovered by AV IP Utility or Costar Utility.


Verify physical connections and power requirements for the specific camera.

a.Refer to the datasheet of the product regarding PoE / Auxiliary power requirements.
b.Ethernet runs should be no longer than 100 meters using either EIA/TIA 568A or 568B standards.
c.Use a PoE injector to bypass any potential network issues.
d.Verify the NIC on the camera and switch are lit.
a.Test or replace the cable as needed.
b.Bypass the Ethernet pigtail on the camera.
c.Move the camera to a different port on the switch.
d.If these are managed switches, verify PoE is enabled and that there are no security policies in place that would prohibit the camera from coming online.
e.For Contera cameras, try to press and hold the physical reset button for 10 -15 seconds.


1.Install AV IP Utility or Costar Utility on the PC:
2.Set your Ethernet adapter to DHCP.
 Both tools find cameras regardless of what network scheme the cameras are on.
3.For AV IP Utilityverify the Ethernet adapter is enabled.
 Discovery > Select Network Interfaces > Select the local Ethernet interface > Click Refresh Camera list > Click OK.

4.If neither tool is able to discover the camera they will look like the below.



5.In these instances, we need to install Wireshark ( as there may be something blocking camera discovery.
6.Install Wireshark accepting all the defaults.

7.Launch Wireshark then double click on the Ethernet interface.

10.You should see an ARP entry similar to the one below. The camera IP in the below example is and the last 6 digits of the MAC address on the second line are 1B-25-8A.

11.If you open a webpage to you should be able to configure the camera.
12.If the camera is found using this method, you will need to reach out to local IT to identify if there is something on the PC or network that is blocking the camera discovery.

Password Reset Failure


The key file fails to erase password, even with admin rights and after the ARP Table confirms routing.

Note: This is only for Gen 1 Arecont Vision cameras. This will not work on Contera series cameras.


You can deploy firmware as an alternate way to reset a camera’s password, but you must use an older version of deployment software “without authentication“.

NoteBefore updating firmware, stop all streams and views from the camera.

1.Download and extract the attached firmware loader utility to your desktop (attached below).
2.Right-click FirmwareLoader.exe and select Run As Administrator.
3.Select Find Cameras — This creates a firewall exception for the tool as well.
1.If the camera is found: Increase the camera’s timeout to 1000.
2.If the camera is not foundEnter the camera’s IP Address and Increase the timeout to 1000.
4.Select Upgrade Firmware.
5.Find and select the firmware you want to update to (in most cases, this is the same version as currently installed on the camera).
6.Select Open. The update may take some time to complete.

Use a constant ping to monitor for a reply from the camera to confirm the process has completed. The camera should no longer require a password. If you can go to the camera’s IP address in a web browser without being prompted for user and password, the process was successful.
