B1W is best budget. It's good also and cheaper.

Er... It's hard to compare A129 Duo series and B1W as A129 Duo is a dual dashcam and B1W is a single dashcam.

If you're in KL, Sicurez is authorized Viofo distributor/seller/installer in Sunway.

A129 Duo IR is more for interior recording. If you drive Grab will be good to get the A129 Duo IR. The A129 Duo is front and rear.

So in the will need to know what is your dashcam requirements and budget.

Getting 2 B1W is workable but you'll need to think where to plug 2 dashcams for power (the cable for the rear is it long enough) & get 2 micro SD cards.
