About this app

Security Camera CZ is a security camera app with more than 6 years on the market. It helps to a million of users in many countries by turning their old smartphones into home security cameras. This app is designed for parental monitoring, property monitoring, pet monitor, dog monitor, baby monitor, webcam, nanny cam, IP cam and much more. It is FREE to use including ALL FEATURES!

HOW IT WORKS
By installing Security Camera CZ on your old unused Android smartphone you get a home security camera with a live cam including a walkie-talkie, motion detection, alerts about detected motions and much more. You can add as many cameras as you want to create an all-in-one security camera system. You then watch your camera anytime from anywhere on your personal phone by installing the Security Camera CZ in monitor mode, even from the other part of the world.
If you are looking for a surveillance camera app, pet cam app, dog camera app, baby camera app or webcam app, this is a choice. The app is regularly updated, so in contrast to dedicated security camera systems, you get regularly new features and functions.

FEATURES – all are included in the FREE version!
LIVE STREAM: live camera in HD quality anytime from anywhere, including walkie-talkie and option to record what you see.
MOTION DETECTION: Exceptional resistance to false alarms, option to record as images in high resolution or as videos with sound.

WHEN TO USE

This is what I wanted! Has all the functions that I needed, good enough for the free version. Even the yearly sub is worth it, less than the monthly subs you pay for. This is play and forget, I do everything in my phone all day and can then check the recordings. I got this app so I can find out which of my dogs is misbehaving and I already have 2 successful catches in less than a week of installation! I have tried many other free apps and this is the best one yet.

After a couple of days the app turn off the camera. The phone doing as camera has all the settings right to be always active. so it is not permissions problems or inactivity problems. message for developer: you didn't understand, when I check the phone it is toggled off. it is not about resources, it has just your app. Not sure if you can see the logs.

Hi, when the camera "turns off", can you check if the app is still running on the phone or is the app on the phone shut down? It can happen that the Android system automatically shut down running apps when it has not enough resources. I would recommend to uninstall old apps from the phone to free up resources and restart the phone.
