When your device restarts, it will send a ping to the IP address 192.168.1.128 from Uboot mode. If the device successfully pings this IP, it will use it as the server address to upgrade the firmware package stored there. Keep in mind that this upgrade process will erase all device configurations, including the device IP address.

How to Download Firmware for Hikvision Devices

Keeping your Hikvision devices up to date with the latest firmware is essential for ensuring optimal performance, security, and access to new features. If you’re looking to download firmware for your Hikvision product, here’s a straightforward guide to help you navigate the process.

Step 1: Visit the Official Hikvision Website

The first step in downloading firmware is to head over to the official Hikvision firmware download page: Hikvision Firmware Download. Once you’re there, look for the “Support” or “Downloads” section. This part of the site is dedicated to providing resources, including firmware updates for various Hikvision products.

Step 2: Select Your Product

In the downloads section, you’ll need to find the specific model of your device—whether it’s a DVR, NVR, or IP camera. Simply type in your model number or navigate through the categories until you locate your device. This ensures that you find the firmware version that is compatible with your equipment.

Step 3: Contact Technical Support

If you run into any trouble finding the specific firmware you need, don’t hesitate to reach out to Hikvision’s technical support. They can guide you through the process and direct you to the correct firmware for your device. Having expert assistance can be invaluable when you are uncertain about which version to download.

Step 4: Check with Authorized Distributors

Sometimes, authorized distributors or resellers also have firmware available for download. If you can’t find what you need through the official website or technical support, it’s worth checking with these sources as they may provide additional options or versions of the firmware you’re looking for.

Important Reminder

Always ensure that you are downloading firmware specifically designed for your model. Using the wrong firmware can lead to compatibility issues that could affect your device’s functionality. Take the time to verify everything to avoid any potential problems down the line.

Upgrade Steps

1. Network Setup:
   • Ensure that both your camera and computer are connected to the same network segment. Disconnect any other devices to keep the network clean.
2. Assign IP Addresses:
   • Set your device’s IP address to something like 192.168.1.XXX (replace XXX with a unique number).
   • Assign your computer the IP address 192.168.1.128.
3. Access the Camera:
   • If everything is configured correctly, you should be able to access the camera through your web browser. If you cannot access it, Double-check your IP settings.
4. Place the Firmware Package:
   • Move the firmware file named digicap.dav into the same folder where the TFTP tool is stored. Then, launch the TFTP tool.
5. Start the Upgrade:
   • Power off your device and then turn it back on. It will automatically begin the firmware upgrade process.
6. Upgrade Confirmation:
   • Once you see a message indicating that the upgrade package has been completely sent to the device, you can close the TFTP tool. Wait for the device to finish writing the new firmware.
7. Monitor the Upgrade (Optional):
   • If you have a serial cable, you can monitor the device. When you see the message *****UPDATE COMPLETE*****, the upgrade has succeeded. Go ahead and power off the device again.
   • If you don’t have a serial cable, just wait about 10 minutes after closing the TFTP tool, and then power off the device. It will become inactive but will work normally after activation.

Important Notes

1. Backup Configuration: Since the TFTP upgrade wipes all configurations, make sure to save your device settings beforehand and re-import them after the upgrade is complete.
2. Manual Restart: After upgrading, you will need to restart the device manually as it won’t do this automatically.
3. Close the TFTP Tool: Remember to close the TFTP tool before you restart the device. If you don’t, the device may try to upgrade again upon reboot.

By following these steps, you should be able to successfully perform a TFTP firmware upgrade on your device!
