dash cam by lenses

Dash cams record at resolutions from 1080p Full HD up to 4K/Ultra‑HD. Examples in the results include 2560×1440 (QHD) and true 4K (4096×2160), with many models using 1080p for rear or cabin channels while offering higher resolution (e.g., 1440p or 4K) for the front camera.

Reported aperture values include F2.7, F2.0, F1.75, F1.8 and F1.5. Across the models shown, lens apertures range roughly from F1.5 up to F2.7.

Some dash cams integrate ADAS features linked to their camera and processing setups. The results cite forward collision warnings, lane departure warnings, pedestrian and rear collision alerts, stop‑&‑go assistance, and lane‑change assistance among the features offered.

You’ll find dual‑channel (front + rear) setups and 3‑channel systems that add an interior/cabin camera. The 3‑channel kits described cover front, cabin, and rear with wide‑angle lenses to broaden coverage.

Models offer several mounting and adjustment options, including articulated brackets or gimbals, swivel mounts, and mirror‑style strap mounts. Documented adjustment examples in the results include an 88° adjustable gimbal and swivel ranges up to 330°, but exact mounting hardware and angle ranges vary by model.

Many dash cams include Wi‑Fi and companion smartphone apps for live view, playback, and downloading files. Built‑in GPS/location logging is common, and some devices offer cloud backup or remote live‑view features (the latter often requires a subscription and an active connection).

Loop recording with segmented file lengths and automatic overwrite is widely supported. Impact/G‑sensor file locking and parking‑mode recording are also cited. Memory support varies across models — examples include support up to 256GB or 512GB, some devices include a microSD (32GB or 64GB), and others note that a card is not included.
