Doorbell Wire Check product guide
Arlo Video Doorbell 2K (2nd Gen), Wireless or Wired
A 2.4GHz home where live view and basic alerts are enough without a plan
Arlo's second-generation 2K doorbell runs on a sealed rechargeable battery or on existing doorbell wiring, which also trickle-charges it and connects it to your traditional chime. Live streaming, motion alerts and two-way audio work without a subscription; 60-day history, AI detections and emergency response need a paid plan after the included trial. The manual quotes two different transformer voltages, so check yours first.

Which model, and what the box holds
Amazon's overview gives the model name as Video Doorbell (2nd Gen). The quick start guide is more specific and covers two model numbers, AVD3001 and AVD4001, dated March 2025. Arlo's own troubleshooting advice is to find your doorbell's model number on the box it came in, and it matters because the app asks you to pick the right model during setup and, in Arlo's words, only tries to discover the device you select.
The quick start guide's box list is the doorbell with its mounting plate, a USB charging cable, a wire extension kit, an optional angled bracket, a release pin and a screw kit. There is no indoor chime and no power adapter for the charging cable; the manual says the USB-C cable connects to a USB charging port or an AC adapter, and that it is for indoor use only.
The battery is integrated and cannot be removed. Charging means using the release pin to open the back cover, plugging in the USB-C cable and bringing the whole doorbell indoors. The LED goes solid blue at 100 per cent, and Arlo recommends a full charge before setup.
The chime question, and a power kit the box list does not mention
Arlo lists four ways to hear a ring: an Arlo Chime 2, your home's traditional chime, a smart-home voice assistant, or a video call to your phone. Wiring is what connects it to the traditional chime. The manual is direct: "Hardwiring your doorbell lets you connect it to your home's existing chime and allows the doorbell to trickle charge when it's not in use."
For the chime to ring, the setting in the Arlo Secure app has to be set to Mechanical or Digital to match what you actually have, and Silent mode has to be off. The manual's troubleshooting section then describes an Arlo Power Kit attached to your doorbell chime, with a switch that puts it into Bypass mode. Bypass mode means the doorbell is not electrically connected to the chime, so the chime will not ring; Arlo recommends turning it on if your chime rings or buzzes at unexpected times or if the doorbell LED is amber during setup.
That Power Kit does not appear in the quick start guide's box list for this product. We are not going to guess whether one is supplied, sold separately or carried over from another model's manual. If your plan depends on keeping your existing chime working, ask Arlo whether a Power Kit comes with this ASIN before you order.
Two different transformer numbers in the same manual
The hardwiring chapter states the requirement as an approved external power source with an output rating of 8-24Vac, minimum 0.65A, 50/60Hz, at an ambient temperature of 45°C minimum. That 0.65A floor is a more demanding way of stating the requirement than the VA figures most doorbell makers print, and it is worth measuring against before you buy.
The troubleshooting chapter of the same manual says something different, twice. The Bypass mode section opens "even though the voltage level of your doorbell transformer is 16-24 VAC", and the LED troubleshooting section says to make sure "the voltage of your doorbell transformer is between 16-24V AC". Eight volts and sixteen volts are not the same starting point for an old house.
Both figures are Arlo's, printed in one document. We publish both rather than pick one. If your existing transformer sits between 8 and 16 volts, that gap is the thing to resolve with Arlo support before ordering, and the manual itself twice tells you to consult an electrician if the doorbell will not work after wiring.
Placement, the motion window, and the network it wants
Arlo asks for the doorbell about 4 feet (1.2 m) above the ground, with a clear view of the approach, and gives a 6 mm (15/64 inch) drill bit for the two screw holes, recommending the supplied wall anchors on drywall. The angled mounting plate, included, tilts the view left or right. One detail shapes where it can go: the manual says the lower half of the field of view is the motion-sensitive part, and that the doorbell starts recording when it detects motion in that area.
The network requirements are firm. The doorbell joins a 2.4 GHz network only, the phone's Bluetooth must be on during pairing, and Arlo recommends placing the doorbell within 10 to 15 feet (3 to 4.5 metres) of the router during setup before moving it. Afterwards it should be within 300 feet (90 metres) of the router line of sight, reduced by every wall and obstruction, and at least 6.5 feet (2 metres) from any other Arlo camera. Arlo lists thick walls, brick, concrete, stone, ceramic, glass and mirrors, metal and large volumes of water as things that cut the signal, and says ports 443 and 80 must stay open on the router.
There is a mesh caveat many buyers will not expect. The manual says some Wi-Fi extenders or mesh satellites might cause more power consumption on the doorbell, and suggests connecting to the router itself rather than a satellite. It also warns that activity zones filter notifications but do not save battery, because the doorbell still monitors the whole frame.
Heat, power loss and the behaviours that surprise people
The manual contains a temperature rule worth knowing before you mount this in full sun. If the wired doorbell heats to 149-185°F (65-85°C), the Arlo Secure app disables your chime while the doorbell continues to operate. Above 185°F (85°C), the doorbell stops functioning until it cools down. A doorbell that stops ringing the indoor chime on a hot afternoon is working as designed, not faulty.
A wired unit that loses voltage sends a "Power interruption at [TIME]" notification, which means the doorbell has no voltage or its wires are disconnected while your Wi-Fi is still up. After power returns, Arlo says to allow about ten minutes for the doorbell to come back online, and to restart it from the app if it is still down after twenty.
Two more behaviours. If a visitor rings and you decline the call or do not answer within 20 seconds, the doorbell prompts them to leave a message, which is saved as a doorbell recording in your feed. And if you set the doorbell up wire-free and later decide to hardwire it, the manual says you must first remove the device from your Arlo account and then re-add it following the wired instructions. That is a full re-onboarding, not a settings change.
What the subscription controls, and the coverage it carries
Arlo draws the line clearly on the listing: "Live streaming and basic alerts work without a subscription", and "A paid plan is required after trial" for the rest. The listing includes a one-month trial of the Arlo Secure Early Warning System, and the disclaimer says that after the trial a paid plan is required to keep 60-day video cloud storage, AI-powered features, smart detections and 24/7 emergency response. The manual footnotes Quick Reply as a subscription feature too.
Amazon's detail fields give a sense of what the plan layer includes: 60-day video history, 24/7 professional monitoring and emergency response, audio detection for bark, scream, glass break and gunshot, AI-generated event captions, and a "Theft Replacement Coverage" field that reads "Included with plan". That last one is unusual enough to be worth confirming directly with Arlo, including what it requires of you if a doorbell is stolen.
Other fields worth checking against your own needs: IP65 weather resistance, a night-vision range of 25 feet in black and white, a built-in siren, single-band Wi-Fi, and an Apple Home requirement of an Arlo SmartHub. The description also states plainly that the device is for use in the USA only. We found no warranty term in the two documents we read; Amazon's page says the manufacturer's warranty can be requested from customer service, so get it in writing before you buy.
