Torn between a few dashcams and unsure what to choose.

Mini 0806 from Gearbest (around RM370)

Pros

1. Small, therefore hopefully does not attract much attention.
2. Good video quality (based on the video samples)

Cons

1. Warranty may be an issue since there's no local distributor here.
2. No parking feature
3. Memory card purchased separately

Transcend Drivepro 200 (around RM470)

Pros

1. Has wifi capabilities.
2. Good video quality (based on the video samples)
3. 160 degrees angle
4. Capacitor based
5. Nice design
6. Comes with 16GB memory card

Cons

1. It's huge!!!
2. No parking feature
3. No GPS feature

Transcend Drivepro 220 (around RM500)

Pros

1. Has wifi capabilities.
2. Good video quality (based on the video samples)
3. Has parking feature
4. Lane departure warning system
5. Forward collision warning systemc
6. Comes with 16GB memory card

Cons

1. It's huge!!!
2. Glossy black in color, which screams, "Steal me! Steal me!"

Being said that, which one should I choose?

That sounds interesting!

1. Will it void the car's warranty?
2. Will it drain the car battery?
3. Once it starts recording when it detects movement, it will record for 5 minutes and then shut off again and starts recording if there's movement again?
4. When it says hardwire, does it mean soldering or just... "plug and play?"

Thank you.
