For an empty house, the trap is not the camera — it is the connection. If everything runs on WiFi, then the day the internet drops you are not being watched and nobody tells you.
Half of Lebanon is looking after a house they are not standing in. The family flat while everyone is abroad, the village house closed from October, the shop after nine.
The questions are always the same three, and they are cheap to answer.
The three questions, and what each one costs
| What you want to know | The part | Price |
|---|---|---|
| Is anyone inside or at the door? | Indoor camera | from $24 |
| Has a door or window opened? | Door / window sensor | $7 |
| Is there water on the floor? | Leak sensor | $12 |
| Did the power come back? | Any metering plug | $8 |
| Will I be told if the internet is down? | GSM alarm, on a SIM | $55 |

The detail that decides whether any of it works
An empty house has nobody to reset the router. So the failure runs in one direction: power drops, router dies, and every WiFi device in that house stops reporting. The camera is not broken. It is simply alone.
There are two honest ways to deal with that, and you can do both.
Keep the router alive. A DC UPS for $18 — the whole story is in the router guide.
Do not depend on the internet at all. A GSM alarm carries its own SIM, so it calls and messages you over the mobile network. When the line is down, that is the one thing still talking.
For a house you visit twice a year, an alarm on a SIM card beats a better camera on WiFi.
The cheap version that covers most of it
If the house is checked on now and then and you mainly want to catch a problem early, this is the practical set. A camera to look, a sensor on the door, and a leak sensor on the floor of the bathroom or next to the tank.
The leak sensor is the one people skip and then wish they had not. Water running for a week in a closed flat does more damage than a break-in.
Careful
A leak sensor tells you. A smart water valve actually shuts the water off. For a house standing empty for months, the valve is the one worth the extra money.

Is the house alright? — the whole answer
Together: $43.00
Camera to look, door sensor to know, leak sensor to catch the expensive one early. Add the DC UPS if the house has nobody to restart the router.

Keeping the router alive through a cut — without this, most of the above goes quiet at the worst moment.
The water came at 2 a.m. — if the house has a tank and a pump, this is the other thing worth watching remotely.
