Another product’s video displays with a DDNS connection

Applies to: HRX-435(FN)

Issue Summary

An NVR needing repairs was replaced with a replacement (used) at a site. Using a mobile DDNS connection caused a problem where the site video was shown to the previous user.

Wisenet DDNS works with the MAC address and key value. If the user of a device with a specific MAC address changes, the previous user can still view the video.

Other users can access the DDNS when: 

1. The existing user has not deleted the corresponding device ID from Wisenet mobile.
   
   
2. A security company manages a single DDNS with identical IDs and passwords in common. 
   
   
3. The device list has not been deleted from the Wisenet DDNS.
   
   The automatic registration integrated with P2P is not applied in this case.

Resolution

To avoid this issue:

1. Do not use substitutes (used products). Reselling our products to others is not covered by the warranty.
   
   
2. Provide on-site customer support with new products.
   
   
3. When the IP address of the device has changed, connect to Wisenet DDNS and update the new IP address information.
   
   
4. When disposing of the product, follow the procedures below to ensure that no customer information remains.
