Both are good battery-powered wifi camera systems. A few points of comparison:
- Eufy stores videos locally, while Blink has free Amazon cloud storage (limited but sufficient). Some may worry about privacy with cloud storage.
- Eufy batteries are not replaceable, so the whole camera needs to be replaced when the battery stops taking a charge. Blink takes AA lithium batteries.
- Blink is much less expensive when on sale, especially if you need a number of cameras. Blink 5 camera kit was recently on sale for $379.
