Smart pet device safety: power cuts, portions, cameras and cold

Assume the power will fail, because it will

A feeder on mains power with no battery backup is a bowl that beeps. The test takes about 5 minutes: fill the hopper, set a feed for two minutes from now, pull the plug, and see whether the meal arrives. Some devices hold the schedule and dispense on batteries, some hold the schedule and dispense when power returns, and some lose the schedule entirely.

Write down which of the three your device does, because the right response is different in each case. A device that dispenses late is a minor problem; a device that forgets the schedule needs a second check after every outage, and that is a habit rather than a setting.

Four D cells at an example $3.50 each is $14 of insurance, and the cautious interval is yearly, because a backup cell that has sat flat for 18 months is not a backup. Note the date on the cells with a marker when you fit them, which is the only way anyone remembers.

Check the portion the feeder actually drops

Feeders meter by volume and food is sold by weight, so a feeder set to one portion does not necessarily drop the grams you intended. Kibble size and shape change the volume-to-weight relationship between one bag and the next, and a feeder calibrated on small pellets over-dispenses on large ones.

The check is to weigh what comes out, for 3 consecutive days, on a kitchen scale, and compare it with what the app says it delivered. A difference of a few grams is noise. A consistent difference of 20% is an extra portion every five days, which over a year is a visible change in a small animal.

Re-run the check whenever the food changes, which is the point most households skip. A hopper quoted at 6 L holds roughly 2.5 kg of a typical dry kibble, so a new bag is also a new calibration, and at 150 g a day it is about 16 days before you would notice by eye.

1. Weigh the empty bowl, then weigh it after each scheduled feed for 3 days
2. Compare the measured grams with the portion the app reports
3. Treat a consistent gap above 10% as a calibration problem rather than noise
4. Repeat the 3-day check after every change of food
5. Keep the hopper lid sealed, because damp kibble bridges and jams the auger

A camera in your home is a camera on someone's server

The Office of the Privacy Commissioner of Canada advises buyers of smart devices to establish what personal information is collected, whether it is shared with third parties, how long it is retained and whether it can be deleted. For a pet camera the honest answer is that it records the room, which means it records whoever is in the room.

Its security recommendations are concrete. Change the default password and user name on the device, because defaults are widely published. Put connected devices on a separate guest Wi-Fi network protected with WPA2 rather than on the network your computers use. Activate only the functions you want, avoid devices with always-on microphones, and switch off location, Bluetooth and Wi-Fi when they are not in use.

Two more steps apply when a device leaves the house. Reset it to factory defaults to erase your personal information, and remove it from the account as well, which is a separate action on most platforms. A camera sold second hand with its cloud account still attached is the worst outcome available in this category.

Cold shortens everything outdoors

Environment and Climate Change Canada publishes a wind chill value whenever the temperature is 0 °C or below and the wind is 5 km/h or higher, and attaches a freezing time to the colder bands. In the -28 to -39 band exposed skin can freeze in 10 to 30 minutes; in the -40 to -47 band it is 5 to 10 minutes; at -48 to -54 it is 2 to 5 minutes.

Those figures are about people, and they are the right frame for how long a walk should last and how long any device is expected to sit outdoors on a collar. Batteries deliver less at low temperature than at room temperature, so a tracker quoted at 6 days in mild weather should be planned around a shorter interval in January, and charged before the walk rather than after it.

The department also warns that in sustained winds over 50 km/h frostbite can occur faster than the published times indicate. On days like that the useful setting is a shorter reporting interval on the tracker and a shorter walk, in that order, because a tracker reporting hourly tells you very little about an animal that has been gone 20 minutes.

Check the recall database, before and after

The Government of Canada's recalls and safety alerts database held 19,875 active alerts and 14,449 archived alerts when this guide was checked, covering consumer products alongside food, health products and vehicles. Searching a model name there takes under a minute and is the one check that costs nothing at all.

Do it twice: once before buying, and once a year afterwards for anything that contains a battery, a heater or a motor. The database lets you subscribe to notifications, which turns the yearly check into no check at all, and it is the sensible arrangement for a household running three or four of these devices.

It also matters for anything bought second hand, where the original owner may never have seen the notice. A device that was recalled in 2024 is still on kitchen floors in 2026, and the database is the only place that record is kept in one piece.

Before you buy

• Run the plug-pull test on any feeder on the day it arrives, before relying on it
• Date the backup cells with a marker and replace them yearly
• Weigh the dispensed portion for 3 days and compare it with the app
• Repeat the weighing check after every change of food
• Change default passwords and put every connected device on a guest network with WPA2
• Factory reset and remove from the account before any device leaves the house
• Check the wind chill band before a long walk and shorten the tracker's reporting interval
• Search the recalls database before buying and subscribe to alerts afterwards

Questions readers ask

How do I know whether my feeder has real battery backup?

Pull the plug with a feed scheduled two minutes ahead and watch what happens. There are three outcomes: the meal dispenses on batteries, the meal arrives when power returns, or the schedule is lost entirely. Run the test on the day the device arrives, while it can still be returned, and repeat it once a year when you change the cells.

Why does my feeder's portion not match the app?

Because feeders meter by volume and food is sold by weight. Kibble size and shape change the grams in a given scoop, so a feeder calibrated on small pellets over-dispenses on large ones. Weigh the dispensed food for 3 days against what the app reports, and repeat that check every time the food changes.

Should a pet camera be on my main Wi-Fi network?

The Privacy Commissioner's minimum recommendation is a separate guest network for connected devices, protected with WPA2. The reason is containment: a camera with a weak login on the same network as your computers is a route to those computers. Setting up the guest network takes about 10 minutes on most routers and is done once.

How long can a tracker last in a Canadian winter?

Less than its quoted figure, because batteries deliver less at low temperature and the quoted days assume a reporting interval. Treat a 6-day claim as a mild-weather number, charge before the walk rather than after, and shorten the reporting interval on the days when it matters. The walk itself is bounded by the wind chill band rather than by the battery.

Is it safe to buy these devices second hand?

With two checks. Search the model in the Government of Canada recalls and safety alerts database, which held 19,875 active alerts when this guide was checked, and confirm the previous owner has factory reset the device and removed it from their account. A camera still attached to someone else's cloud account is the one case worth refusing outright.
