Content: An enhancement for Viofo firmware is proposed to introduce switchable parking mode profiles, providing tailored operational configurations. For example, in environments where enhanced surveillance is required, a profile could be configured for maximum recording quality, uninterrupted power supply from an external power source, and the disabling of power-saving features. Conversely, alternative profiles could be activated for standard scenarios, initiating a transition to low-power modes after a specified duration. The implementation of this functionality via direct camera inputs or accessory Bluetooth buttons would facilitate a more streamlined user experience, mitigating the need for application-based configuration and network switching.

I’m upgrading my photo workstation mainly for Lightroom Classic AI Denoise, Photoshop and AI plugins (Retouch4me etc.).

Current setup:

• Ryzen 9 5950X
• 32 GB RAM
• Kingston KC3000 NVMe
• GTX 1660 Super
• Seasonic Focus Plus 550W Gold

Right now AI Denoise takes ~55 seconds per RAW, so the GPU is clearly the bottleneck.

My original target was RTX 5060 Ti 16GB, but the used market is frustrating – good deals are rare, and many used cards are priced surprisingly close to an RTX 5070 12GB.

I briefly considered a regular RTX 5060 8GB because it’s cheap and easy to find, but after reading about Lightroom 14.5+/15 and GPU-accelerated previews, the 8 GB VRAM started bothering me, so I ended up looking at the 5060 Ti 16GB again.

From what I’ve gathered, many Lightroom users get around 6-10s AI Denoise on anything from a 3060 Ti to a 5080, so the DNG creation/storage step becomes a bottleneck and the fastest GPUs don’t scale much.

So my dilemma is:

• RTX 5060 8GB – cheapest, easy to buy, probably already a huge improvement over my GTX 1660 Super.
• RTX 5060 Ti 16GB – lower power draw, keep my 550W PSU, more VRAM for future Lightroom/Photoshop workloads.
• RTX 5070 12GB – similar price on the used/outlet market, but less VRAM and likely pushes my 550W PSU much harder.

For people actually editing large RAW catalogs every day: would you choose 16 GB VRAM on the 5060 Ti, or the extra compute power of the 5070 for Adobe workloads?

Hey everyone, I wanted to share a quick troubleshooting fix for the VIOFO A329S that almost made me drive back to my installer to complain. I couldn't find this documented anywhere in the official manual or online forums, so hopefully, this saves someone else a headache.

My Setup:

• Camera: VIOFO A329S 2CH
• Power: VIOFO BP100 LiFePO4 Battery Pack (hardwired)

The Problem:

After picking up my car, I sat down to configure my parking modes in the VIOFO mobile app. Whenever I tried to select Low Power Impact Detection (or Hybrid Parking), the app blocked me with this annoying pop-up:

My wiring was 100% correct (power cable plugged into the top of the GPS mount, rear camera into the side). Other parking modes (like Low Bitrate) activated with zero issues. I immediately panicked, thinking the installer bypassed the ACC wire or made a mistake in the fuse box.

The Troubleshooting & Undocumented Logic:

Before calling the shop or making an unnecessary trip back to the installer, I decided to do some smart troubleshooting. I used Gemini to help me research the error and dig through deep forum logs. Together, we cracked VIOFO’s undocumented firmware logic:

1. When your engine is off, the ACC line has 0V.
2. Because there is no active ACC signal at that exact moment, the camera's processor cannot verify if it's connected to a proper 3-wire hardwire system (HK4/HK6/BP100) or just a basic 2-wire USB power supply.
3. To protect itself from boot-loops or draining the battery in case someone actually used a cheap 2-wire cable, the firmware blocks saving to Low Power and Hybrid modes when the engine is off.

The 10-Second Fix:

1. Start your engine (this sends 12V to the ACC line and tells the camera a 3-wire system is present).
2. Connect your phone to the camera's Wi-Fi.
3. Open the VIOFO app, go to Parking Mode, and select Low Power Impact Detection (or Hybrid).
4. Tap OK — it will save instantly with zero error messages!
5. Turn off the engine — the camera will transition into your newly selected ultra-save mode perfectly.

Dear u/VIOFO-Dashcam, please update your PDF manuals! It says absolutely nothing about needing the engine running specifically to toggle these parking modes in the app.

Hope this saves you from pulling your hair out! Safe driving!

Hi everyone,

I'm getting a new car soon (Skoda Octavia IV) and I'm currently torn between two flagship setups: the newest VIOFO A329 (or A329S) and the newly revised DDPAI Z90 Master. I do mostly short city trips (grocery runs, commuting), which makes parking mode efficiency a huge priority for me.

I'm leaning towards VIOFO for the video quality, but I have a few major concerns about their ecosystem:

1. Power Drain in Parking Mode: VIOFO's buffered parking mode is notoriously power-hungry. Since I do short trips, a dedicated dashcam battery pack might not even have time to fully recharge between drives. Does the new A329's "Low Power Impact" mode or optimized Time-Lapse actually solve this battery drain issue in real-world usage?
2. SD Card Pickiness: VIOFO seems extremely sensitive to SD cards, practically forcing the use of high-endurance models (like Samsung PRO Endurance) to avoid constant error beeps.
3. Bulkiness: The physical footprint of the main unit is quite large and hard to hide behind the rearview mirror.

On the other hand, the official distributor for DDPAI recently told me about a new revision of the DDPAI Z90 Master. They claim it now features 128GB of built-in eMMC storage and, most surprisingly, Dual 4K Sony STARVIS 2 (IMX678) sensors for BOTH front and rear cameras, plus a CPL filter out of the box.

My questions for both DDPAI and VIOFO users:

• Is the DDPAI claim true? Has anyone actually verified if the rear camera on the newest Z90 Master is a genuine 4K IMX678? Most DDPAI dual setups usually have a basic 1080p rear camera.
• Parking Mode Comparison: How does the DDPAI Z90 Master handle parking mode compared to VIOFO? Since I lack the driving time to charge a dedicated power bank, which camera's parking mode is safer for a standard car battery (or a small capacity power bank) without missing crucial hit-and-run evidence?

Any insights from owners of either system would be greatly appreciated!
