Pick a PoE doorbell if your door has Ethernet, and a battery doorbell that can use your doorbell wires if it only has those. With neither, a battery doorbell on its own works. So the wired vs battery video doorbell choice starts with what’s at your door. Two of the three doorbells here can run on a battery or on wires, which is also the short answer to the Ring doorbell wired vs battery question.
| Product | Power | Chime | Saved video without a plan | Recording modes |
|---|---|---|---|---|
| REOLINK 2K PoE Wired Video Doorbell | PoE, or 12 to 24V AC wiring plus Ethernet | Included plug-in chime | Yes, microSD up to 256GB or a Reolink NVR | Motion, 24/7 or scheduled |
| Ring Battery Doorbell 2K | Built-in battery, trickle-charged by wires or solar | Existing chime, if it’s on Ring’s list | No, a Ring plan is needed | Motion events, saved with a plan |
| aosu 5MP Wireless and Wired Video Doorbell | Battery or wired | Built into its aosuBase Mini | Yes, 8GB on its aosuBase Mini | 60-day loop recording |
Reolink sells its model as the Video Doorbell PoE. Ring’s was the Battery Doorbell (2nd Gen) until August 2026, when Ring renamed it the Battery Doorbell 2K. On its own store, aosu calls its doorbell the Video Doorbell R1 Ultra.
Wired vs battery video doorbell: start at your door
Find your door, then check what else you’ll need.
- Ethernet at the door, or a way to run it: get the Reolink. PoE (Power over Ethernet) means one Cat5e or Cat6 cable carries power and data back to a PoE switch, a PoE injector or a Reolink PoE NVR. None comes in the box. Neither does a microSD card. If you add an NVR, check its model and hardware version on Reolink’s support list. Skip the Reolink if no cable can reach your door.
- Doorbell wires only: get the Ring. It runs on its battery without them, but wired to a transformer giving 8 to 24 VAC, it trickle-charges. Wired through your old chime, it rings that too, if the chime is on Ring’s compatibility list. Check the list first, because Ring warns that an incompatible transformer or chime kit “could damage your devices.” Skip the Ring if you won’t pay for a plan to keep its video.
- Nothing at all: the Ring or the aosu, on battery. The Ring needs a USB-C cable for charging, and none is in the box. To hear it indoors without wiring, Ring points you to a Ring Chime, a Chime Pro or an Echo speaker. The aosu rings through its aosuBase Mini instead, an indoor hub that also stores its video and extends its Wi-Fi. Skip the aosu if you don’t want a second box to set up inside.
What the wires do on each doorbell
Wires do a different job on each. The Reolink has no battery and no Wi-Fi. It runs on PoE to the IEEE 802.3af standard, on 12 to 24V AC doorbell wiring or on a 24V DC adapter. Wiring or an adapter still leaves it needing Ethernet, because Reolink says it “can only get a network connection through a network cable.”
The Ring is a battery doorbell first. Its built-in battery charges over USB-C, and wiring “will provide a trickle charge to the battery,” Ring says, as does a Ring solar charger. So on the Ring doorbell, wired vs battery isn’t either-or.
The aosu runs on its battery or on wired power. Wired, it never needs recharging. But aosu doesn’t say whether that power comes from doorbell wiring or which transformer it needs, so read its manual before you count on your old wires.
Will your old chime still ring?
With the Ring, yes, once it’s wired through that chime and the chime is on Ring’s list. With the Reolink, no, and aosu doesn’t say for its doorbell. The Reolink “will not work with the existing mechanical chime,” Reolink says. So a plug-in chime comes in the box. Reolink’s doorbell and chime can’t work with other brands’ doorbells or chimes either.
Wiring the Reolink to doorbell wires takes one of two routes. You can bypass the old chime with a jumper cable from the box, which silences that chime for good. Or you can wire the doorbell straight to the transformer. Whichever doorbell you wire, cut the power first. Ring’s guide says to “Shut off power at the breaker.” If you can’t tell which breaker it is, Ring says to switch off the master breaker or call an electrician. Reolink’s guide says to power off the doorbell system too.
Picture and saved video on a wired or battery video doorbell
Line up the three makers’ specs, and resolution doesn’t follow the power type. Both the wired-only Reolink and the battery-or-wired aosu shoot 5MP, while the Ring’s 2K video is a square 1920 x 1920 frame. That’s about 3.7 million pixels against 4.9 million on the Reolink’s 2560 x 1920, so the other two give you more to zoom into on a face or label. All three see wide: 180° diagonal on the Reolink, 173° diagonal on the Ring and 166° on the aosu.
Saved video splits them more sharply. The Reolink records on motion, around the clock or on a schedule, and it keeps the 6 seconds before motion is detected. Clips go to a microSD card of up to 256GB or to a Reolink NVR, with no subscription. The aosu stores clips on its 8GB aosuBase Mini with 60 days of loop recording, and no subscription is required. Its cloud plans are optional.
The Ring needs a plan. Without one, Ring says live view still works and you can answer alerts as they come in, but reviewing recorded video takes a subscription. With a plan, Ring keeps motion videos for up to 180 days, and its Smart Alerts for people and vehicles need one too.
Alerts work differently on each. The Reolink detects people and lets you draw motion zones. The aosu pairs radar and PIR sensing with AI human recognition, and you can set zones on it too.
What each costs to buy and to run
On cost, the plan matters more than the wired vs battery video doorbell split. At their makers’ own US stores, the aosu costs more than the Ring. The extra money buys a 5MP camera, a chime in its base and saved video with no plan. If live view is all you want, the Ring’s lower price wins, but once you want recordings, its plan becomes a running cost the aosu doesn’t have. For the Reolink, budget for the PoE gear and card from the door list above.
When the Wi-Fi or the internet drops
Offline, the Reolink keeps recording and the Ring doesn’t. Without internet, Reolink says its doorbell still detects motion and people and records to its microSD card. If its chime is connected, it still chimes when pressed, but alerts and live view stop until the connection comes back.
When the Ring falls offline, Ring says live view, alerts and event recording all stop. It needs your home Wi-Fi, and Ring recommends an upload speed of at least 10 Mbps. It won’t work on a phone hotspot. Because its video quality can also vary with your internet bandwidth and the doorbell’s temperature, test your upload speed at the door before you choose the Ring. The aosu’s maker doesn’t say what its doorbell does offline.
Charging and renting: life with a battery doorbell
Charging is the chore on the battery side of a wired vs battery video doorbell choice. Only two of these three have a battery to look after. Ring gives no battery life for the Battery Doorbell 2K. Its general battery page says Ring batteries are “made to last for months between charges,” and that a full charge may need up to 10 hours. To charge, release the doorbell from its bracket with the included removal tool, then plug in a USB-C cable. If it’s wired to a chime, Ring’s steps start with shutting off power at the breaker and disconnecting the wires. Wired in, it takes the trickle charge instead, which is the everyday Ring doorbell wired vs battery difference.
The aosu’s battery figures differ: up to 180 days on aosu’s own store page, and an average of 90 days on its Amazon listing. Neither says how often the doorbell is triggered.
For renters, the hardwired vs battery doorbell question mostly settles itself. On battery, the Ring and the aosu need no wiring at all, though both still screw to the wall. Ring estimates about 10 minutes to install the Battery Doorbell 2K. The mounting hardware is in the box, and Ring’s guide lists a Phillips-head screwdriver, with a drill and masonry bit as optional. The Reolink is the hard one to rent with, because the cable has to reach the door. It does come with a 15° wedge for angling the camera.
Doorbell questions
Ring doorbell wired vs battery: does wiring add features?
Wiring the Ring Battery Doorbell 2K adds charging and can ring your old chime, but it doesn’t add 24/7 Recording. Ring’s 24/7 Recording list leaves out every battery doorbell, wired or not. Ring also limits Advanced Pre-Roll to “all wired Video Doorbells and Security Cameras” without saying a wired battery model counts.
Does a battery video doorbell work in freezing weather?
A Ring battery doorbell keeps working in the cold, down to -4°F, but its battery drains faster. Ring says battery life “will not be as long” around freezing and that it stops charging below freezing, so charge it indoors by USB. The wired Reolink is rated only down to 14°F.
