Which is better for watching a driveway and a side gate?

The C420S2, because two cameras are included and each can be mounted where the view is needed without wiring. The C246D covers two areas from one spot only if both are within its wide lens and pan/tilt range.

Does the C246D need a subscription?

No. Person, pet, vehicle and baby-cry detection run on the camera, and it records to a microSD card up to 512 GB. The C420S2 also works without a plan but leans on its hub for local storage.

Which has better picture quality?

Both are 2K. The C246D is 2304 × 1296 at 15 fps; the C420S2 is 2K QHD at 20 fps, so motion looks slightly smoother. The C246D adds a 6 mm telephoto lens for zoomed detail.

Which lasts longer outdoors?

The C246D is IP65-rated and rated for -4 °F to 122 °F, so it is built for permanent outdoor mounting. The C420S2 is outdoor-rated but runs on batteries you recharge, so plan on periodic trips to each camera.

Is the C246D worth the extra over the C420S2?

The C246D has sold for $54.98 to $64.99 since October 29, 2026, for one camera. The C420S2 is a two-camera kit, so check its current price: if you need two locations covered, the kit is usually the better value.
