V402r11 H264 H265 Dvr Nvr Firmware Download Work Better
Updating the V4.02.R11 firmware for H.264/H.265 DVRs and NVRs is a precise process that depends on matching your device's specific 8-digit Version ID. This firmware is typically associated with Xiongmai (XMeye) devices built on Hisilicon SoCs like the Hi3520D, Hi3521A, or Hi3536. Step 1: Identify Your Version ID
Checklist:
- [ ] USB 2.0 Drive (16GB or less, formatted to FAT32). Do not use USB 3.0 or exFAT.
- [ ] Exact Filename Match: The firmware file must be renamed to what your bootloader expects. Common names:
update.bin,digicap.dav,firmware.img. - [ ] Power Stability: Connect the DVR/NVR to a UPS. A power loss during firmware flash = permanent brick.
- [ ] Disable H.265+: Before updating, go to the camera menu and set encoding to H.264 temporarily. This prevents codec conflicts post-update.
Copy Files: Copy the .bin or .dav firmware file directly to the root of the USB drive. If the download is a .zip, unzip it first. Initiate Upgrade: Insert the USB into the DVR/NVR. Go to Main Menu > System Setup > Utility > Upgrade. Select the file from the USB drive and start the process. v402r11 h264 h265 dvr nvr firmware download work
