Have had the device for almost a year now and I can say it's very convenient.

The included RF (radio frequency) monitor is easy to use and connects instantaneously after setup and I have yet to go anywhere in or around my three story brick house that is out of range.

I also heavily use the app on multiple android devices. There is a 5-10 second delay as it connects via WiFi or as much as 20 seconds if remote like at work. The app notifications are good, I use motion only (not noise) as I have two very barky dogs! I find the app extremely helpful if I am in another room and didn't bring the included monitor with me (it has a good battery length though). I also like the app as on Android (not sure iOS) you can leave it open and multitask and still hear the audio.

People have mentioned the delay in moving the camera remotely but I find I almost never do that once it was set up. There is also a delay with the "Talkback" feature, but again not something I use super heavily and I can wait 5-10 seconds.

The other in app features I use include taking pictures (to send to the grandparents) and checking the temperature as the baby's room tends to be quite different from the rest of our house.

The rest of the Motorola Hubble ecosystem didn't come out until after we had our baby and other products or I would have likely purchase other app compatible products.

I've recently bought one these after some research I did on internet reading reviews.
The camera is quite good, the image is clear and the night vision is also quite hi-res and clear. I was expecting the camera has onboard battery and I only would need to recharge that, but it is not so. The camera has to be plugged to the outlet all the time. The pan & tilt of the camera is good, the envelope is good, but the tilting range could be better.
One draw back though with the camera is on the bottom surface, there are just two holes to hang the camera on nails on the wall, but it would be very nice if there is another threaded hole for tripod attachment.
The display quality of the monitor is quite good. The menus are not so good. The wireless range of the display is not that great. So don't expect to use the display from the other side of your home.
However, the Hubble for Motorola app is quite good. I'm using the IOS version, so I can only speak for that. It works on wireless and 4G. I can easily run the app and get camera image on my phone from office. There are triggers in the app that enables warnings to be displayed on your phone when the camera captures sound or motion.

not sure why there are many negative reviews. may be they wrote the reviews when it had crappy iphone app. it worked perfect for me and i love the camera a lot. here are some pros and cons according to me.

pros:
- i tried to test the microphone by coughing about 25 feet 3 rooms away. i could clearly hear myself. great that i can peacefully watch a movie when my baby is sleeping and be sure i can hear her wake up.
- looks great. i could see how a big name company can make great quality products.
- very easy setup using iphone app
- app is working great. has all options that i needed (notifications for sound and motion, background running to listen to baby waking up etc.)
- small in size, hidden infrared rings
- the notifications are displayed in order. great feature. like a security system.
- supports WPA2 security. i have 2.4 ghz and 5ghz router. it showed all the 2.4 ghz bands. was successful connecting to older wep and newer wpa2 wifi security

cons:
- there is a lag of about 1 second from the camera. compared to foscam where is lag is less than quarter second. i am okay with the lag of about a second.
- iphone app forgets the password. the bug was fixed in a weeks time
- camera pan and tilt is not smooth. works for me since i hardly change the viewing angle. it will be difficult for someone who regularly tries to logon and do pan/tilt. but since it is software issue hope it gets better
- clarity of the camera is 720p. i notice it is less clarity compared to 1080p foscam. does not matter to me since i use it for baby monitoring and not theft kind of situations where higher clarity may be need.
- i don't remember seeing the option to set the clarity. it is just 1 hour since i setup the camera. may be i did not check the settings completely. also software issue and i hope it is addressed soon

I am a bit of an expert on security cameras so when buying a baby monitoring camera, had a bit of a high standard.

I have been very impressed with this camera and monitor. Its not perfect in every way, but it is largely good.

Pros:
1) Image quality is excellent. Plenty of Infrared lighting for good night time viewing and true to color in daylight.
2) Sound quality is excellent. You can tell a cry from a whine from a grunt without issue
3) No delay. More and more data being transmitted with these cameras means more chance for delay. Across our large home delay is less than .5 a second.

Cons:
1) Sound is a bit quiet. Not too quiet, but a bit quieter than I would prefer
2) Hubble app never worked right. This is a minor issue.

Read all the reviews, and compared all the cameras. I consider myself VERY tech savvy but did want a camera that was easy to operate for non-tech folks. Camera is very easy to setup - up and running in minutes using provided instructions. Wanted a camera that pans/tilts, zooms, temperature, phone app, remote/web viewing. Video recording and 2 way voice communication was on my wish list, but not deal makers. Built-in lullabies are 'electronic' versions of common songs, and sound ok.

At first was very upset with the purchase. Previous negative reviews held true. Then after approx 1 week. the following happend:
1) Firmware on camera was auto-updated (camera automatically talked to Motorola server for update, was unaware this was going to happen until it did)
2) iPhone app was updated

since then, almost everything works great.

Here are the problems/issues at present:
1) IMHO, the camera is choppy on public wifi. Works great over cellular. Works perfect on local/home wifi. There is a delay on the video, and in my experience is it 2) Remote viewing outside of wifi uses Motorola server as a middle-man. Occasionally server is not accessible, and will give outage for 10-30 minutes. No prior notification is provided via email, website, or other method that this is going to occur.
3) Phone app shows an option to buy Motorola's cloud recording service. This is ever-present. Also frequently receive emails to buy/try cloud service.
4) 2 way intercom is horrible - as works on an intercom / walkie-talkie method of communication (unlike cell phones). Would not use this as a selling point, but it is present if needed/desired.

Overall still happy with purchase and will probably buy another if needed.
