Pros & Cons
Arlo Pro Security Camera 2K HDR, 6th Gen (VMC4070P)
Pros
- +8-month battery claim is the longest rechargeable figure here outside eufy's solar cameras
- +No SmartHub required, which is exactly what separates it from the Ultra 3 sitting above it
- +Swappable battery plus USB-C means no ladder trip and no proprietary charging puck
- +160-degree view and 2K HDR make it the sharpest sub-$150 battery camera in this set
Cons
- −Arlo's free tier is the harshest in the category: live view and a notification, and that is all — no recording whatsoever
- −Local storage needs a SmartHub you buy separately plus a microSD you also buy separately
- −Arlo Secure Plus for one camera is $9.99/mo, and unlimited cameras is $19.99/mo — the most expensive per-household plan here
- −No RTSP, no ONVIF: an Arlo is worthless the day Arlo turns the servers off
- −Arlo does not publish frame rate, bitrate, IP rating or the usage assumption behind the 8-month battery number
Arlo Ultra Security Camera 4K HDR, 3rd Gen — 2-Cam Kit with SmartHub (VMS5250-100NAS)
Pros
- +180-degree field of view genuinely removes the blind spots a 140-degree camera leaves at a corner
- +SmartHub is in the box on this kit, so local microSD recording is a card away rather than a $100 accessory away
- +Auto-Zoom and Tracking in 4K is the one feature here that no cheaper camera imitates convincingly
- +USB-C battery and swappable cells mean the camera stays on the wall for its whole life
Cons
- −4K recording and streaming require Arlo's higher Secure Plus tier — on the base plan you get a 4K camera producing 2K files
- −Trusted Reviews found the 4K stream runs at the same bitrate as the 2K Pro 6, so 4K here mostly buys compression artefacts
- −The SmartHub is mandatory. Buy a single Ultra 3 or an add-on camera and it is inert until you also buy a VMB5000
- −The microSD card is never included, on any Ultra 3 SKU
- −$349.99 for two cameras before you have paid a cent of subscription, and no plan means no recording
