Dear Customers :

With the popularity of network video surveillance, more and more networking products are used in public networks, such as Network Video Recorders, Network Cameras, and Routers. But the public network environment is more vulnerable than internal network. You devices might be attacked by various viruses, like malicious network scanning if the devices are used in public networks without any modification of their default passwords.

We get to know some of our customers do not change the default passwords, which might cause heavy damages and losses.

Therefore, we hereby strongly recommend you to change the default passwords of the networking devices before using in public network.

We appreciate for your continuous supports to HIKVISION.

Dear Valued Partner,

Hikvision has  determined that there is a scripted application specifically targeting  Hikvision NVRs and DVRs that meet the following conditions: they have  not been updated to the latest firmware; they are retained as the  default port, default user name, and default password.

Hikvision has introduced secure Activation Mechanism into all of product lines since March of 2015, it is required to create  password when first login. However, it was possible, before that date,  to install NVRs and DVRs with default settings. Therefore, we provided  updated firmware which includes this mandatory setting for customers to  upgrade existing devices.
 
Hikvision strongly recommends that our  customer base review the security levels of equipment installed prior  to March 2015 to ensure the use of complex passwords and upgraded  firmware to best protect their customers.

Below are firmware and password guidelines and specific steps to take to secure a system:


Password and Firmware Overview


•     Leaving factory-default, poorly chosen, or weak passwords in your  camera or video recorder may result in unauthorized access or  exploitation of your company resources.

•    Change every password in every device occasionally. Old passwords can carry additional risk.

•    Ensure all systems have the latest firmware.

•     All users, including contractors and vendors with access to your  company systems, should take appropriate steps to select and secure  their passwords and update your firmware on your system.


Password and Firmware Steps

 
1.    Make sure to have your device behind a firewall.

o    Make sure that your firewall is updated with the latest firmware and that the default password is changed on your router.
o     If you want to have your device work with a Hikvision or third-party  online services, make sure to set up port-forwarding on your firewall.

2.    Check if your system has the latest firmware. Here is a link to  check if your product needs to be upgraded to the latest firmware.


3.    After updating firmware, please restore factory default, and ensure that you have restarted your device.

4.    Once the device is restarted, it will ask you to give a more secure password.
o    Go through the process to secure your devices.

5.    Now that you have updated your device please make sure to change your password regularly.
