Vantrue N5 vs VIOFO A329S 3CH: N5 adds a second cabin angle, A329S offers a separate SSD driving archive

Check these before buying

• Keep the original N5 four-channel base kit and A329S 3CH front, fisheye cabin and standard inside-window rear kit. N5S, A329S 2CH, waterproof-rear and telephoto packages are different purchases. Check the seller’s actual package, condition, cables and return terms. No current price, stock or delivery advantage is claimed.
• N5 includes the rear module, GPS mount, vehicle charger and 20-foot rear cable. A microSD card, CPL filter, remote and parking hardwire kit are separate. A329S 3CH includes the cabin and rear cameras and a front CPL, but card, SSD, SSD cable and hardwire kit are separate. The family manual labels secondary cameras optional because it covers other packages too. That does not remove the cameras from this selected 3CH kit.
• Before fixing the mounts, power the cameras and check every road and cabin view with normal seat and headrest positions. N5’s rear-cabin lens must face into the vehicle, following the orientation diagram. A329S’s cabin camera uses its own cable to the main unit. Measure both complete cable routes rather than choosing a length from a vehicle-size label. Keep equipment and wiring clear of driver visibility, controls and airbags. Standard rear modules belong inside the rear window.
• Use the appropriate vehicle power supply through the GPS mount. N5’s supplied charger is the documented driving connection, not an assumed USB-C PD fast-charger substitute. On A329S, the main-body USB-C socket is also the SSD/data port and does not support hardwire parking power. Use the GPS mount’s power port for the hardwire installation. The short data cable supplied for transfer is not the vehicle charging or dedicated SSD cable.
• For the A329S archive, verify the exact portable SSD against current manufacturer compatibility guidance, buy the VIOFO Type-C SSD cable, format to exFAT before use and select External SSD in Video Storage. Formatting erases existing data. Secure the drive without obstructing the driver and keep it out of high heat. VIOFO recommends a 0 to 60 degrees Celsius SSD environment. Check recorded files after installation and retain copies elsewhere.
• Turn A329S Privacy Mode off when the goal is a driving archive. With it on, 3CH retains only the latest six normal files and uses one-minute loops. Manage SSD Storage can explicitly copy the last 24 hours, seven days or all available microSD files to the SSD. That command is separate from normal recording to one selected target. It cannot restore files already overwritten. No automatic simultaneous duplicate recording is promised.
• To review SSD footage, remove the drive and connect it to a computer with the data cable, then open its DCIM videos in VIOFO Player. With a usable microSD card already inserted, A329S switches new recording to that card after SSD removal. Without the card it asks for one. Check the active target after reconnecting the SSD rather than assuming an old archive choice remains selected.
• If A329S Hybrid or Low Power Impact parking matters, install a separate high-endurance microSD card and compatible VIOFO hardwire kit through the GPS mount. Both modes save only to microSD. Hybrid needs either Cut-off Time or Cut-off Voltage set, and voltage-based switching specifically needs HK6. Its transition into impact detection is not a promise of continuous video afterward. Time-lapse parking omits audio. VIOFO advises turning the camera off above 60 degrees Celsius inside the car.
• N5 parking needs stable continuous power and ordinary time-lapse off. Vantrue advises switching off at 60 degrees Celsius in the car. Powered motion detection can add ten seconds before movement to its thirty-second clip, but that is not collision-detection prebuffer. Event locking is disabled with loop recording off or ordinary time-lapse on. Export important event and parking clips promptly because their folders are not permanent archives.
• N5’s selected listing gives 512GB while its current manual and support give 1TB. Confirm exact card and firmware compatibility before buying a larger card. This comparison leaves the maximum unresolved. A329S lists up to 512GB microSD or a separate compatible SSD up to 4TB. File load, modes, protected clips and actual formatting affect usable retention, so no cross-model multiplier or promised number of days is given.
