4K T800 バンドル：フロントカメラ＋リアカメラ＋メモリーカード＋ハードワイヤーキット＋CPLフィルター＋バッテリーパック

Wasn't expecting the battery pack to matter this much, but parking mode actually runs overnight now without draining my car. The rear cam footage was clear enough to catch a plate when someone tapped my bumper in a lot. Having the 512GB card and hardwire kit in the same box saved me a second order.

The CPL filter made a bigger difference than I expected — dashboard glare is basically gone on sunny drives. Installing the hardwire kit took me about an hour but now it records parking incidents without draining the battery.

Went with the bundle instead of piecing it together myself and the 512GB card alone made it worth it, no more worrying about old clips getting overwritten. The hardwire kit was the part I dreaded installing, but it's been clean and the parking mode actually catches stuff overnight.
