A229 Pro: price the camera and its power system
For front-and-rear recording, the A229 Pro is a concrete starting point. Parking recording adds a second purchase decision: how the camera gets power while the car is off. The HK4 is a matching accessory, but the complete bill also includes suitable memory, fuse accessories and installation if you are not doing the work.
Shortlist: 3 options, selected for meaningfully different fits, budgets or system approaches. Compare the exact variant and total installed cost.

VIOFO A229 Pro 2CH
A front-and-rear camera system with parking recording available through the optional HK4 hardwire kit.
Before ordering: Budget for the correct hardwire kit and a supported endurance memory card. Parking duration depends on the power source and cutoff settings.
The matching power accessory for an A229 Pro installation using vehicle battery, accessory and ground connections.
Before ordering: Have the fuse locations and routing verified for your vehicle. A low-voltage cutoff is a safeguard, not a guarantee of next-morning starting.
If you only need driving footage, start with the supplied normal-power arrangement. Choose hardwiring when parked coverage justifies the installation and battery trade-off. Short trips and a tired starter battery are reasons to reduce parking coverage or use a properly specified independent power solution.

Fit and purchase checklist
Verify the vehicle’s 12-volt accessory architecture and approved hardwire points.
Choose a parking-mode cutoff that protects the starting battery for the vehicle and climate.
Check whether the camera records on motion, impact, time lapse or continuously.
Estimate card storage from published bitrate and overwrite behavior.
Avoid interfering with airbags, driver sightlines, defrosters and safety sensors.
Check whether parking coverage is supported in the manufacturer’s exact installation kit.
The costly mistake
The crispest footage in the world is not useful if its camera flattened the battery overnight.
