Security Camera System SC27

Since your cameras have a base station, they were already connected/paired with the Monitor(Base Station) when you received them.
We simply need to connect the Monitor(Base Station) to the WiFi.
Plug the camera to a power source and connect the system to the app by scanning the QR-CODE on the Monitor(Base Station) using the APP.
Then you can view the live views.

If the device is offline:
Confirm that the network is steady, and that the router's WiFi is set to 2.4GHz network mode without changing.

If one of the cameras is offline or the live view is black.
We have to ensure that the camera is plugged firmly without lose. Perhaps you can plug it with a new working power cable and adapter.
After that, check if you can see a live view of the camera after turning it on again

If you are still unable to see the camera in the APP.
Reset the issue camera successfully first(press the reset button for at least 5 SECONDS).
To reconnect the camera, please refer to the screenshot. And then you will see the live view of the camera again.

Yes, it supports two-way talk via the APP.

Yes, it has to be 2.4Ghz WiFi.
Please confirm that your router operates at a 2.4 GHz network frequency(some routers support both 2.4 GHz and 5 GHz).
It is not cellular data, but rather a method of router operation that may be configured and validated after signing in to the router.
For your reference, the information on how they differ is provided below https://networkshardware.com/2-4ghz-vs-5ghz/

It can work without the internet, but we'd better have a successful network connection at the first use.
After successfully connecting to the internet, add it to the app to make sure all cameras are added successfully(can see live views of all the cameras).
Then disconnect the network, at this time, the camera will record, but not through the APP remote monitoring.

The maximum number of cameras that the Monitor(Base Station) can support is 4.
Should you wish to add an additional camera to your current suite, please do not hesitate to contact us so that we can recommend a compatible camera model.
We advise against purchasing cameras from other suppliers, as this may result in compatibility issues.

The system works with a Max 128GB Micro SD card, please make sure to insert it into the Monitor(Base Station) but not the camera.

Under ideal conditions, the camera can be positioned within 65-100 feet of the Monitor(Base Station);
however, the actual range varies based on factors such as wall thickness, indoor obstructions, and Monitor(Base Station) location.
If the camera and Monitor(Base Station) are in an open outdoor location with no obstructions, the connection distance can be up to 330 feet.

This monitor includes two lithium batteries. When an external power supply is plugged in, it charges the battery.
When the external power supply is withdrawn, the lithium battery powers the Monitor.

1. It can be used to connect the mouse and perform the same function as touch.
2. lt is used to connect the U disc and backup video files. Please restart the system once you've inserted the U disc.

One camera can be connected to a single Base Station, but the base station can not be connected to a Screen Monitor or a TV.

The alarm messages in the event can not be deleted. These thumbnails are retained in the app's cache data, and the thumbnails in events will be automatically cleared after three days.
If you want to delete specific videos. You can format the memory card in the APP, but this will delete all the videos saved in the memory card.
Or you can read the memory card on the computer by a card reader to choose the single videos you want to delete.
