YES. TWO OR MORE Devices CAN Use and CONTROL at the same time!
You do NOT have to have a paid Mubview service account to have more than 1 device, use and control this security doorbell at the same time. It took me almost a month to figure out how. I almost returned it, until I figured out the solution to the problem. Full instructions are below.You can easily share the device, via the app, but for some reason, I couldn’t figure out how to share it. I tried inviting my husband by his email, but it wasn’t working. He could sign into the app on his phone. But, when he did, it threw me out, and vice versa. I tried making his own mubview account, but that didn’t work.I’m very good with computers and technology. My older husband is awful. I finally brought him into the 21st century, kicking and screaming, when his flip phone battery died for the umpteenth time, with no replacement (yup, you read right. That was 2018!). I had the wireless carrier fire up one of my older Note phones for him. So, he’s up to the Note 9 now, only because I refuse to give up my Note 10+ (and he gripes to me every day, wanting that flip phone . It dawned on me why the sharing wasn’t working just 2 days ago.I have very few apps on his phone, for obvious reasons. He doesn’t know how to email or text (you read THAT right too!). I maintain an email account for him on my phone. No one in their right mind would text him. But, the Note 9 is also in my name. I’ve never even thought of opening a Samsung account in his name. Why would I?I had deleted the mubview account I had made in his name, in the mubview app, on his phone. First, I had to remake the account. Then, I made him a Samsung account on his phone, which identifies the phone with his email account. THAT was the missing element.I went into my app, clicked “share” put his email in, then sent it. When I signed into HIS mubview account on his phone, in the mubview app, the invitation was there. All I had to do was accept it for him.99.9% of you won’t have the problem that I had, assuming your spouse is at least minimally computer literate. My husband, who’s 24 years older, ain’t gonna learn computers at 86 years of age, especially since he has his own tech troubleshooter right there to help him!But now he can look at what’s happening live on the front porch and street, without kicking me out of the app.To cap it off, this is how you get more than one device to work with all aspects of the doorbell:1. Download the mubview app.2. Using their email address, make a NEW ACCOUNT on the mubview app, on their phone.3. Make sure that whomever has the phone, has an account with the phone manufacturer (in this case, it’s Samsung).4. Go into the mubview app on your phone and invite the person, using their email address.5. The person with whom you’ve invited, must sign into their mubview app (on their phone) to accept. This will be under SETTINGS –> DEVICE SHARE. They need to ACCEPT. All involved now have full access and control, AT THE SAME TIME!As far as the functionality of the doorbell system, we can’t be happier. I cannot think of a single thing I would change. When someone rings the bell, both of our phones ring like doorbells. You answer with your phone and talk to whomever is out there. It’s really cool.You can change the viewing/security area in the app, and control sensitivity. The view is sharp, even across the street. The view is black/white near infrared, at night, but we have motion lights on the porch. The image goes to color when they’re activated. I’ve had the doorbell installed for a month and it doesn’t need recharging yet. I turned down the sensitivity, because it was alarming (to the phone) when the school buses were picking up and dropping off kids. It’s been good at differentiating humans, but we have a pair of Robins with babies on the front porch. Although I’ve blocked out the nest, if one flies in front of the camera, we get an alert.The doorbell hardware is well thought out. You must install it (if using screws) from the inside of the box. The box locks into place. They give you a “key” which must be used to push in the release. The release is out of view, under the device. You can go into the app for live viewing, talk to anyone 2 ways usIng the intercom, set off an alarm, take a screen shot, or video, right from the app. Mubview even provided a 32gb mini SD card for recording.I think Mubview thought of everything and then some.

Battery issue
I have J7 for 2 years working very good at front door ,no need for cloud storage just insert a sim card ,battery life more than 2 months , then recently I bought J9 for the backyard , a beautiful doorbell camera but unfortunately has a battery issue keep drained quickly and getting empty in 2 days and sometimes in hours and turned off because of dead battery however customer service took care of that , the seller is realy responsible and takes any problem very serious to solve it ,the unit I received had defective battery but not every J9 , I also knew that J7 and J9 use the same battery ,I recommend mubiew doorbell cameras , good quality for the price , very easy installation, I use 3 cameras in one account and gave my wife access as well

Excellent door bell camera, images are very clear, great product and price is good too, had this for a few weeks now no issues, very easy to install and great quality images will definitely be buying more cameras to add for more security.

I was looking for an entry model doorbell camera that was not hardwired when I found this one. The reviews were good so I tried it out, I have not been disappointed. Great battery life, clear picture, easy controls and app. I am very happy with my purchase. Not sure how it is going to hold up in -45 weather here in Canada but at least as it is not hardwired I can remove it and take it inside for the winter, I will test it to see though. It is a really great doorbell camera at a really good price point. Try it out, you will not be disappointed.
