Q - Does the pet camera work with 5GHz wifi? A - No, it only works with 2.4GHz wifi. If your router is a dual-band, we recommend you separate them first and then connect the camera to the 2.4GHz band. Q - Do I have to subscribe to the cloud? No, the cloud is not mandatory. A - The camera can record events (up to 12 seconds) in the last 24 hours. But if you need to record longer videos, please insert a micro SD card or subscribe to the cloud. Q - The camera won't connect. A - Please long-press the reset button until the camera makes a sound and the light starts flashing red, then try to connect it again. Q - Can I view the camera on different phones at the same time? A - Yes. Please note that one blurams account cannot be logged on different phones at the same time. Please register a new blurams account and share the camera with the new account. Then you can view it on multiple devices simultaneously. Q - Any problems with camera use? A - You can find us on the product box! We are happy to help you!
