Only 16GB of storage onboard ; Night footage gets motion blur

Mostly painless install ; Local video storage ; User-friendly app ; Wifi bridge/doorbell chime included ; No subscription necessary

A lock calibration override option would be useful ; Motion detection sometimes delayed by a couple of seconds ; SD card for storage not included ; Currently only offered in black

No 24/7 recording ; Speaking through camera was buggy ; Less-than-stellar response to security flaw discovery

Excellent camera with lots of features ; Attractive (if enormous) hardware ; Huge rechargeable battery

Sometimes misses events, both motion-based and physical ; Fingerprint reader is difficult to work with ; Doorbell button isn’t obvious to visitors

This massive smart lock probably won’t make you a convert of the doorbell-camera-lock combo idea, but it has plenty of positive qualities that could make it worthwhile for some users.
