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.

Honestly, it's better than most apps like it because you can actually utilize ALL the cameras imo. I wanna be a little nitpick-y about not being able to "look around" when you zoom in, but honestly, for the rest of it working as good as it does while being free, I can't complain. The UI is super easy to navigate, the quality is hella good, and the features are super nice. I love that it will highlight movement, and I do enjoy the ability to actually use my wide-angle lense 🥰

Nice. A very pleasant app to use. No nasty surprises, only the good kind. For example... it was a bit cumbersome to turn off the camera remotely. Then, I accidentally swiped the camera image and found the shortcut! Also, I reduced the sensitivity to eliminate false triggers from shadows or reflections and that just works perfectly. Setting the detection area dialed it in even more. Save to Google Drive... nice! All free. Even though the ads are not obnoxious I'm buying the ad-free version soon.

I tried many apps (I think 5 or 6 others). This one is the best. Reliable, easy to set up, surprisingly great quality. Being able to change the areas of movement detection (with really specific quadrants) is a nice touch . I have one on my window ledge to watch the front door/driveway and one to watch my pets while I'm gone. The only thing I wish I could change is zooming into specific areas instead of just zooming into the center. But definitely not a deal breaker for such a great free app.
