- Which is better for seeing faces at night?
- The Eufy SoloCam E30. Its 2K sensor keeps more detail than the Blink's 1080p, and it adds AI that separates people from other motion. The Blink's 700-lumen light does help color night video near the camera.
- Do either need a subscription?
- No. The Eufy records to a microSD card with no monthly fee. The Blink stores clips locally through the included Sync Module Core, though Blink's cloud plans are sold separately.
- Is the Eufy worth more than double the price?
- Yes if you need sharp detail or smart alerts. At $94.99 to $99.99 versus $40.00 at eBay as of November 7, 2026, the Eufy buys 2K video, person and vehicle detection, and free local storage.
- Which is better over a driveway or back door?
- The Blink Outdoor 4 Floodlight, because the 700-lumen light deters intruders and lights the area. The Eufy has no light, only an alarm, so pair it with separate lighting.
- How long do the batteries last?
- Blink rates the Outdoor 4 Floodlight at up to two years on two AA Energizer lithium batteries, though the floodlight shortens that. Eufy does not publish a figure for the SoloCam E30, but its solar panel option keeps it charged.
- Do both work with Alexa?
- Yes. Both list Amazon Alexa support. The Blink adds voice arming and disarming, and live view on Echo screens.
