Which has better coverage, the C246D or the TCW34?

The C246D pans a full 360° and its wide lens is slightly wider at 125.5° diagonal. The TCW34 pans 340°. Both cover a typical yard or driveway; the C246D edges ahead on paper.

Do either of these need a subscription?

No. Both do AI detection for people, pets, vehicles and baby cries on the device and record to microSD up to 512 GB. Cloud storage is optional on both.

Which is better for Apple Home users?

The TCW34 lists Siri, HomeKit and Home Assistant support. The C246D lists only Google Assistant and Amazon Alexa, so pick the TCW34 if HomeKit matters.

Is the 15 fps limit on the C246D a problem?

It is fine for watching a yard or doorway, but fast movement will look choppier than a 30 fps camera. The TCW34 does not publish its frame rate, so confirm before buying if smoothness matters.

Which is better at night?

The TCW34 advertises color night vision; the C246D uses 850 nm IR LEDs rated to about 40 ft. Color night vision usually needs some ambient light, so a dark yard favors the C246D's IR.

Is either worth the extra over a single-lens camera?

Yes if you want one camera watching a wide area while a second lens zooms in on a gate or door. If you only need one view, a single-lens 2K camera costs less.

These are close siblings: both pair a fixed wide lens with a 6mm 2K pan/tilt telephoto lens, both add free on-device AI for people, pets, vehicles and baby cries, and both are IP65 with microSD up to 512 GB. The C246D is the newer Tapo-branded unit with a 99 dB siren, 10.8x digital zoom and a 125.5° diagonal wide view; the TCW34 is the same hardware idea with a 340° pan range and Siri/HomeKit listed among its integrations. Prices move on both, so check the current low on each before you commit.
