What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
Arlo Pro 5S 2K
Two whitelisted testers (Tom's Guide and PCWorld/TechHive) hands-on-reviewed this exact model (VMC4060P). Both praise excellent 2K video in daytime and color night vision and accurate person/vehicle/animal detection with robust automation; both flag that an Arlo Secure subscription is required to unlock core features including cloud 2K recording, and that local storage needs a separate $100 Arlo Pro Smart Hub. They diverge on whether the high ongoing cost is worth it. (2 sourced reviews, 2 lab-tested.)
Praised: Excellent 2K video quality in both daytime and color night vision; Accurate intelligent detection of people, vehicles, and animals with robust automation; Long battery life.
Flagged: Arlo Secure subscription required to unlock most core features, including cloud 2K recording; Local video storage requires a separate $100 Arlo Pro Smart Hub; High upfront price (~$250) makes it a pricey investment.
Blink Outdoor 4
Three whitelisted testers (Tom's Guide, TechRadar, and PCWorld/TechHive) went hands-on with the Blink Outdoor 4 and agree it's a top budget outdoor cam: cheap, tiny, easy to set up, with class-leading battery life powered by two AA lithium cells. All three flag mediocre 1080p image quality and key features locked behind a paid Blink subscription. TechRadar and PCWorld both note the manufacturer's two-year battery claim cannot be verified within a review period. (3 sourced reviews, 3 lab-tested.)
Praised: Class-leading battery life (Blink rates two years on two AA lithium cells); Cheap, compact, and very easy to set up; Local video storage via included Sync Module 2 / on-camera image processing for privacy.
Flagged: Only 1080p; footage can look grainy/blurry and trails pricier Nest/Arlo/Ring cameras; Key features (person detection, cloud recording, sharing) require a paid Blink subscription; No pet, package, or vehicle detection.
