What the differences mean

What the battery is for

The Blink Outdoor 4 is battery only, rated for 24 months, with no wired power and no solar. The Eufy Cam S4 has a battery, solar charging and wired power, and 24/7 history only when it is wired. Its battery life is not documented. The Blink is the camera you forget for a year or two. The Eufy is the one that can top itself up in the sun or be wired for continuous recording.

HD against 4K that moves

The Blink Outdoor 4 is HD, not 2K or 4K, with a 143 degree diagonal view, no pan and no color night vision. The Eufy Cam S4 is 4K and 2K, with a 130 degree wide view, a 46 degree telephoto, 355 degrees of pan, 70 degrees of tilt, color night vision and a light. A general look at a porch is the Blink. Identifying and following someone is the Eufy.

Where clips live

The Eufy Cam S4 has 32 GB built in, a microSD slot and RTSP. Cloud is a subscription. The Blink Outdoor 4 has no internal storage and no microSD slot. Its event history and 24/7 history are a subscription, and live view past about 5 minutes is too. It has no RTSP.

Alerts and apps

People, animals and vehicles are included on the Eufy Cam S4, and it has privacy zones and custom motion zones. On the Blink Outdoor 4, person and vehicle alerts are a subscription, it does not detect animals, and there is no privacy zone and no custom motion zone. The Blink works with Alexa and Home Assistant, not Google Home. The Eufy works with Alexa, Google Home and Home Assistant. Neither supports Apple Home.

What owners say

Owners of both want an outdoor camera they can hang themselves, then the stories diverge. Blink Outdoor 4 owners single out a setup that takes minutes and a battery that really does last a long time in ordinary use, plus a wide view, and they complain that person detection and saved video need a plan, that the bundled sync module has no local storage, and that 1080p will not read a face or a plate at distance. Eufy Cam S4 owners praise the second lens following movement in 4K and solar that keeps the pack topped up, and they complain about 2.4 GHz trouble on a busy network, a slow app, and uneven vehicle detection.

Price history compared

Every price change of both, in the same store, so the gap between the two lines is what one costs more than the other.
