The installation depends on what's already at the door. The existing doorbell wiring and its transformer decide whether a wired model will get enough power, the chime inside may need an adapter or a replacement, and the Wi-Fi signal has to reach the front step through an exterior wall. A good installer also sets the angle, motion zones and alerts so the doorbell records your walkway and packages rather than every car that drives past.
Because a doorbell faces the street, it's the camera most likely to capture people who never agreed to be filmed, and because it's connected, its account needs as much care as any other. In a condo or a rental, the door and the hallway may not be yours to change, so ask first.
Wired vs. battery video doorbells: power, features and installation
A wired video doorbell runs off the low-voltage doorbell circuit already found in many homes. It never needs recharging, it keeps the indoor chime ringing, and it's ready the instant someone presses the button because it doesn't have to wake from a power-saving mode. The catch is that it depends on wiring and a transformer able to supply enough power.
A battery doorbell mounts almost anywhere, which suits a side entrance, a house with no working doorbell wires, or a rental where you'd rather leave the wiring alone. It needs regular recharging, and to save power it may record shorter clips or take a moment to start. Some battery models can also connect to existing doorbell wires to stay topped up, a useful middle ground. Whichever you choose, a mount that needs a special tool to release makes the unit harder to walk off with.
Doorbell wiring, transformers and chimes: what your existing setup can support
In most houses with a traditional doorbell, thin low-voltage wires connect the button to a chime and to a small transformer that steps down household power, often mounted near the electrical panel, in the basement or beside the chime. A video doorbell draws more power than a plain button. When the transformer can't keep up, the signs are easy to spot: the doorbell restarts at random, the chime hums or stays silent, or the video drops out.
The installer compares the transformer's rating with what the doorbell requires and tests the old wires, which can be brittle or broken in an older home. Connecting at the button and the chime is low-voltage work, but replacing the transformer means working on the house's line-voltage wiring, a job for a licensed electrician: a Licensed Electrical Contractor in Ontario, or a master electrician who is a CMEQ member in Quebec. A mechanical chime usually keeps working, sometimes with a small adapter; some digital chimes aren't compatible and give way to a plug-in wireless chime, and a house with no chime can send alerts to phones and smart speakers.
Video doorbells in winter: cold batteries, frost and storm doors
- Cold weather shortens a doorbell battery's charge, and some models won't recharge until the battery warms up, so check the manufacturer's operating temperature range before choosing a battery model.
- A wired doorbell, or a battery model kept topped up by the doorbell wires, avoids a dead unit in the middle of a cold snap.
- If the model accepts a second battery, keep one charged indoors so the door is never unwatched while you recharge.
- A doorbell behind a storm door or a glass insert sees poorly through the glass and picks up glare at night, so mount it on the frame outside the storm door or use an angled bracket.
- Mount it under an overhang where you can to keep sleet and blowing snow off the lens, and wipe frost away gently after a storm.
- Short winter days mean more footage in night vision; a porch light on a timer or motion sensor gives clearer images of faces and colours.
Doorbell camera placement to deter package theft
Package theft is often over in moments, so the aim is a clear view of both the parcel and the person's face, plus a setup that discourages the attempt in the first place.
- Mount the doorbell where it shows faces, and choose a model or angle whose field of view reaches down to the doormat, where parcels land.
- Use a wedge or corner mount when the door sits beside a wall, so the camera looks along the walkway instead of at the siding.
- Draw motion zones around your steps and walkway so alerts come when someone approaches, not whenever a car goes by.
- Ask couriers, through your delivery instructions, to leave parcels out of sight of the street, or have them held at a pickup point while you're away.
- Consider a lockable parcel box near the door, and use two-way talk to direct a courier when you're out.
- If a parcel is stolen, save the clip before it's overwritten, then report the theft to the retailer and your local police.
Doorbell camera privacy: the sidewalk, the neighbours and shared clips
A doorbell sits right at the edge of your property: it faces the sidewalk, the street and often the house across the road. Narrow the motion zones and use privacy masking so it records your step and walkway rather than passers-by or a neighbour's front window. The Office of the Privacy Commissioner of Canada suggests activating only the device functions you actually need and turning off a connected camera and its microphone when they aren't in use.
Think before sharing clips. Posting a video of a stranger on social media or in a neighbourhood app can expose someone who did nothing wrong, and images of guests, couriers and children deserve the same care as your own family's. Keep recordings only as long as you need them, and if police ask for footage of an incident, share the relevant clip rather than access to your whole account.
Doorbell camera accounts and cybersecurity: sharing access safely
The doorbell's account shows who comes to your door and when you come and go, so protect it like a banking login. Get Cyber Safe's basics apply: replace default passwords with a unique one, turn on two-factor authentication and keep updates automatic.
- Invite each household member as a shared user instead of handing out the main password, and remove them when they move out.
- If you buy a house with a doorbell already installed, have it removed from the previous owner's account and reset before connecting it to yours.
- Review which linked apps, screens and smart speakers can view the camera, and unlink any you no longer use.
- Connect the doorbell to a guest network if it supports one, which the Canadian Centre for Cyber Security suggests for connected devices.
- If the doorbell is stolen or replaced, remove it from your account right away.
Doorbell cameras in condos and rentals: get the board's or landlord's approval
In a condo, the unit door, its frame and the hallway outside are often common property governed by the declaration and building rules, and a camera aimed at a shared corridor records neighbours every time they pass. Ask the board or the property manager before drilling or mounting anything, and find out whether the building's own door entry system already lets you see visitors.
Tenants should get the landlord's permission in writing before changing a doorbell or its wiring. Models that hang over the door or replace a peephole avoid drilling, but they still need approval and still film the hallway, so keep the view as tight as the device allows. Store the original doorbell so you can put it back when you move out.
Doorbell Cameras: frequently asked questions
Will a video doorbell work with my existing doorbell chime?
Usually, if the chime is mechanical, sometimes with a small adapter installed at the chime. Some digital chimes aren't compatible and are replaced with a plug-in wireless chime or phone alerts. The installer checks the chime and the transformer before you choose a model.
Can I install a doorbell camera without existing doorbell wiring?
Yes. A battery model needs no wiring, and some models can use a plug-in adapter instead. Running new wiring from a transformer involves the house's electrical system, so that part belongs to a licensed electrician.
Why does my battery doorbell die faster in winter?
Batteries hold less charge in the cold, and some models won't recharge until they warm up. A wired connection, a spare battery or a model rated for your winter temperatures keeps the doorbell working through a cold snap.
Can I put a doorbell camera on my condo or apartment door?
Only with approval. Ask the condo board or your landlord first, since the door and hallway may be common property or covered by building rules, and set the camera to record as little of the corridor and neighbours' doors as possible.
I bought a house with a video doorbell already installed. Should I keep it?
Often, yes, once it's reset. Ask the seller to remove it from their account, reset it to factory settings, then connect it to your own account with a new password and two-factor authentication.
