Equipment failures kill tanks fast — and they happen when you're not home
A heater stuck on, a chiller failure, a leaking sump, a stuck protein skimmer — these can wipe out a tank in hours. By the time you get home, it's too late.
Dedicated aquarium webcams are overkill
IP cameras with cloud subscriptions cost $100+ upfront and $5–10/month forever. For a hobby tank, that math doesn't work.
Most cameras upload your home interior to a cloud you don't control
Pointing a cloud-connected camera at your tank means pointing it at your living room too. That feed lives on a vendor's server forever.
Why Call Pet works for aquarium camera app
01
End-to-end encrypted, video stays between your two phones
WebRTC peer-to-peer with X25519 + AES-GCM. The stream never touches a server.
02
Auto-reconnect for unattended 24/7 monitoring
If the network blips at 3am, Call Pet reconnects on its own. You don't have to baby-sit the camera.
03
Spare iPhone or Android — already in a drawer somewhere
An old iPhone 6/7/8 or any spare Android works fine. No new hardware to buy.
04
No account, no email, free basic monitoring
Pair the two phones with a QR code. That's it. No personal data collected, no recurring fees.
05
Two-way audio if you keep the spare phone near a feeder
Position the spare phone near your feeder or sump room and you can use audio to call family members at home if you spot a problem.
Set up in 5 steps
About 30 seconds. No account needed at any step.

Frequently asked
Can I see fine detail like fish gill movement or coral polyps? +
Detail depends on your spare phone's camera. Modern phones (iPhone 8+ or any 2018+ Android) capture enough detail for most aquarium observation. Macro coral inspection is harder.
Will the spare phone overheat next to a warm tank? +
Phones running camera + screen-off + network for hours warm up but stay within safe ranges in a normal room. Don't place directly on a heated lid; keep some airflow.
Is this enough to detect a leak before damage spreads? +
If the camera covers the sump and floor near the tank, yes — you can spot puddles or unusual water levels visually. For early-warning leak detection, pair with a hardware leak sensor.
Can I check on multiple tanks at once? +
Each Call Pet pairing is one Monitor → one Controller. For multiple tanks, set up multiple Monitor phones; switch between them on your main phone.
Does the camera work in low light when the tank lights are off? +
Phone cameras need some ambient light. If you keep a moonlight setting on the tank or a small room light at night, you'll see the tank fine.
