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.
SCHEDULER, NEAR-BY DETECTION, SIREN: to adjust motion detection to your needs.
ZOOM, a LOW LIGHT enhancement, TORCH: to see all you want even in worse light conditions.
CAMERA FEATURES: if your camera supports it, you can choose fish eye or telescopic camera, front of back camera.
HOME SECURITY SYSTEM: easily add more cameras and more viewers/monitors to get home camera security systems. You can have as many cameras as you want.
AND MORE features: share your camera with friends, store to Google Drive, support for IP camera mode, add your camera to Google Assistant…
But do not worry, the app works immediately after installation and all settings are very intuitive. Start now and discover other features when you need them.
Works on WiFi, LTE, 3G or any mobile Internet connection.

WHEN TO USE
In contrast to traditional IP cameras, CCTV cameras or home surveillance cameras this app can be used without any costs if you have some old smartphone in a drawer. Security Camera CZ works even on oldest smartphones with Android 4.1 which were released in 2012 including all features described above.
Security Camera CZ works like a portable CCTV camera, easily to install just by putting the old smartphone to the desired position. If you want DIY your own home security camera or even home security camera system, this is the choice.

FOR BEGGINERS OR ADVANCED USERS
Dedicated CCTV camera, IP camera or surveillance camera may be difficult to install. Installing Security Camera CZ is as easy as installing any app on a smartphone – after installation of the app you immediately get home security system, webcam, pet cam, dog cam, nanny cam or anything you need. And it has more features than dedicated IP cameras, CCTV cameras or home surveillance cameras.

I understand that offline may mean it is unable to connect to it, but that's the issue. I check both devices, restart them, app says its functioning fine on the camera end with my phone next to it and it still wont connect. I have checked my internet as well. Everything on my end was fine. A since fairly recent update it had been working good for awhile but is since another update not working again. A repetitive trend would indicate it's a software issue.

Hello, the app works for others, so I would still think there is some problem with internet connection. Did you also tried to restart the WiFi router? I you write me at my email support@securitycamera.cz we can continue to solve the issue there, if you want.

Been using this app for a while with a cell phone as my security camera. overall I have liked it especially since it's free. But it will randomly stop working. Today I have added another camera to the account and now it's been kicking the monitor phone and the camera phone offline causing me to have to log back in manually on each phone. Meanwhile I think I have security cameras and I actually don't because they've stopped working. If this continues I'll have to find another app.

Hello, adding another camera shouldn't change the app's behavior. Instead, it seems that there is some problem with internet connection on the camera or monitor side. I would recommend to restart everything and if you can, also restart the WiFi router that the camera is connected to. If the problem persists, write me at support@securitycamera.cz

Buggy as hell, and getting help takes several days and the help is "have you tried turning it off and on again?". It works fine for a few days or even a week or more but then it can't connect to the camera anymore and the only way to get it working again is to delete all data and cache from both devices, then reinstall the app, then restart both devices after new installation and then it usually starts working again. Sadly it's still the best one available, even though it's not really very good

Hello, I am sorry about your negative experience. The app works for many thousands users on daily basis, so it should work for you as well. Usually, if the app doesn't work well, especially on old or very old smartphone, a restart of the phone often helps. If you let me know about specific problems you have, I am really ready to help.
