Hi, if you are reading this, you probably got stuck with some issue on the TDI sensor in which after done the necessary troubleshooting and don't seem to find any resolution for it. Well, one think we can do as a last resort is to upgrade the firmware to its latest version. How to execute this ? very simple, just follow the step-by-step guideline below:

1. access this gdrive link and find the TDI sensor model that you wish to upgrade: https://drive.google.com/drive/folders/1dT_QiGkklO2jQxzu8_uz80diJjtTpMRe?usp=drive_link


2. once u have open the folder of your desired TDI sensor model, the zip file are the latest firmware that you can download. however, there are 2 type of zip file
- with logo
- no logo
>> either way, u can download either one of it, its just a matter of updating the sensor webpage UI with the TDI logo.

3. once downloaded, access the sensor webpage via RCS or locally by accessing the sensor IP address.
4. once you are in, go to advance option, under upgrade, choose the select button and find the firmware zip file.

5. the last thing to do is to press the upgrade button, then wait for a few minute for the system to upgrade and reboot.
