How to easily unbind Hikvision DVR/NVR using SADP Tool – If your Hikvision DVR or NVR is still connected to your old Hik-Connect account, you won’t be able to add it to your new account. This is a common issue, especially when purchasing used equipment or transferring ownership. There are several ways to unbind Hikvision DVR/NVR devices. The easiest way is to use the SADP Tool.
In this guide, you’ll learn how to do it step by step. It’s based on hands-on practice, so you can follow it.
What Is SADP Tool?
SADP (Search Active Device Protocol) is a utility developed by Hikvision that helps users detect devices on a local network. This utility also allows you to configure device settings such as IP addresses, reset passwords, and, in some cases, unbind devices.
This tool is especially useful when you can’t access the device through the app.
When Do You Need to Unbind a Hikvision DVR/NVR?
In our experience as security camera technicians, unbinding a device is often necessary if the DVR/NVR is still connected to a previous account and you want to add it to a new account. Or in some of the following scenarios:
- You want to transfer the device to a new user
- You forgot the old account credentials
- You purchased a used device
- You are troubleshooting account binding issues

Alternative Method (If SADP Cannot Unbind)
In many cases, the SADP Tool cannot directly unbind a DVR/NVR device from a Hik-Connect account. In our experience, some devices don’t support unbinding using the SADP Tool. If this happens, here are your options:
- Use Hik-Connect App
- Use Hik-Partner Pro
- Contact Hikvision Support
Conclusion
Unbinding a Hikvision DVR/NVR using the SADP Tool can help you manage and reconfigure your device more easily. However, it’s important to understand that SADP has limitations, especially when dealing with account-bound devices. If SADP doesn’t work, you can use the Hik-Connect app, Hik-Partner Pro, or contact support for further assistance. By following this guide, you can safely handle device unbinding and avoid common issues.
