I purchased the Logitech Circle 2 wired camera. Due to several reported issues by community users with the wireless version such as battery life, video quality, and motion detection I went with the wired version. Please note, most if not all issues, may be resolved by future firmware updates. However, to be on the safe side I purchased a wired version since a battery can be added in the future.

The setup process for the camera was easy. Unfortunately, once setup is complete, if you need to make modifications to wifi ssid or timezone settings you need to reset the entire camera and start all over. A bit strange in this day and age. In any case, you're not changing the settings all the time. The quality of the camera is very good with 1080p resolution enabled. Please note, you do need a strong wireless connection and enough bandwidth to reduce lag in live view. Some users complain there's a lag or recordings take a while to show up in the app. Before you mount the camera into your desired location, grab your cellphone, install a Speedtest app and run a test. If you have a poor upload connection then you're most likely going to have issues. You may need to invest into an Access Point or change the location of your router. Minimum 2 Mbps upload and download speeds strongly recommended

Ring recently introduced a competing product called the Ring Spotlight Cam. I will test that one soon but based on specs and pricing there are a few important differences listed below. I think Logitech can definitely strengthen its offering with the Circle 2.

Price (Wired Version) - Winner: Circle 2
- At the moment Circle 2 wired is priced at $179.99. Ring Spotlight Cam is $199

Resolution - Winner: Tie
- Both support 1080p resolution

Speaker & Microphone - Winner: Tie
- Both have two-way audio

Field of View - Winner: Circle 2
- Circle 2 has 180-degree field of view while Ring Spotlight Cam supports 140-degree field of view.

Siren - Winner: Ring
- Ring has a built in siren that can be triggered to scare off an intruder. It also includes LED lights that can be motion triggered.

Cable Length - Winner: Ring
- Ring comes with a 20ft power cable that's rated for outdoors out of the box. Circle 2 needs a weatherproof extension to be safe for outdoor use.

Mobile App - Winner: Ring
- Ring's mobile app is more polished and feature rich. It also supports the ability to add additional users to access the camera. If you want to share the camera access with your husband and wife it's easy to do so with Ring. Logitech currently support only one account. Ring also allows you to share a video recording by generating a unique URL to video hosted on their servers. With Circle 2, you have to download the recording and then figure out how you're going to send it to someone. Overall, security features and ecosystem in Ring's app is more sophisticated.

Web App - Winner: Tie
- Both cameras have a web interface with their own pros/cons.

Smart Home Integration - Winner: Tie
- Circle 2 will support HomeKit in the future. It will also support the Amazon Echo Show.
- Ring has not announced HomeKit support for its camera but they will most likely have SmartThing integration soon. Which means you can probably automate activities based on motion detection (i.e. turn on lights at night when motion detected).

Subscription Plans (Free) - Winner: Circle 2
- Circle 2 offers access to your recording for free for 24-hours. Person detection, motion zones, advanced alerts, and filters require a paid plan. Ring does not offer recordings for free. You only get access to live streams.

Subscription Plans (Paid) - Winner: Ring
- This is where Ring shines. There are two options for Ring Video Recording: Basic and Protect. Basic costs $3 per month or $30 for the year per device; Protect costs $10 per month or $100 for year, and it covers an unlimited amount of Ring cameras, offers a lifetime product warranty and gives you an additional 10% off future purchases. Logitech is currently charging $10 per month per device or $100 for the year per device. If you own several cameras then this is a pricey solution.

Final Thoughts:
I think Circle 2 is a great innovative device supporting various accessories. However, Logitech needs to invest into better software to be on par with Nest and Ring. For example, it does not make any sense to me why Circle 2 (wired) would not have a motion sensitivity settings. Logitech also need to make their pricing more competitive. I cannot imagine anyone owning several Circle 2 cameras and paying $100/year for each device.

I preordered this camera, but since it was taking so long to arrive, I ended up buying the Arlo Q Plus: Arlo Q Plus - 1080p HD Security Camera with two-way Audio - Free Cloud Storage - Ethernet and PoE (VMC3040S) . I liked it so much I ordered another two, but this time, the original Arlo Q: Arlo Q 1080p HD Security Camera with Audio (VMC3040). I needed one more camera, so I decided to buy the Logitech Circle 2, wired version, to add to the mix. Below is my assessment of the Logitech Circle 2 versus the Arlo Q.

Subscription Plans (Free) -

The Arlo Q (Plus) gives the user 7 days of free recording for up to 5 cameras. The Logitech offers access to your recording for free for 24-hours.

Sharing Accounts -

The Arlo Q gives the user the ability to share each camera with different people. Each person needs to have a NetGear Account. You can give people either Admin access or reduced privileges on a per camera basis. Logitech, currently, only supports one account for all camera connected to your account. This is huge problem for me as I need to give access to different people and some of them should not have full access to the camera controls. For instance, kids, should not be able to turn off the camera in the app.

Field Of Viiew
The Circle 2 has an 180 degree field of view. The Arlo Q only has 130 degeree field of view. So, the Circle 2 is the winner here.

Speaker and Microphone -

Both have two way audio. The audio in the Arlo Q is slightly better then the Circle 2.

Resolution -
Both have 1080 P video, but the Arlo Q is definitely sharper. The Circle 2 is no slouch here, but the Arlo Q's video is definitely better. On a scale of 1 - 100, I'd give the Arlo Q 100 and the Circle 2 a 90. So, again, the Circle 2 video is not bad, it's just not as good as the Arlo Q.

Night Vision
The night vision is very good on the Logitech Circle 2. I would say it is has the same quality, or slightly better, than the Arlo Q.

Mounts -
The Circle 2 have a variety of mounting options for their camera, s o it wins here. However, the base of the Arlo Q is magnetic. This allows you to place the camera on any metal surface. The base of the Circle 2 should have been magnetic as well. Next, depending on the how you twist the head of the Circle 2 camera, the center of gravity of the system may change so much that the camera becomes unstable and tip over. You'll need to really play with the cord, in such a way, as to use it to keep the whole system from tipping over.

Local recording -
The Arlo Q plus allows you to insert and SD card and record locally if needed.

Software layout and features:

Hands down the Arlo Q is the winner here. There is just no comparison. For instance, there are instances where I needed to mount the Arlo Q camera and then video was shown upside down. The Arlo Q has a feature where it can flip the video 180 degrees so that it shows in the right orientation. I can set the Arlo Q to automatically record if it hears a sound as well if it detects motion. Viewing videos is also much easier to look at. The videos are organized in a calendar fashion, which makes it much easier to move forwards or backwards in time. Access to the Arlo Q can be protected by Touch ID on IOS. Circle 2 does not have this feature. Video/Images from the Arlo Q are rotated, on an IOS device, to match the orientation in every direction. For the Circle 2, images are only rotated in from one landscape mode to the other. In portrait mode, the images/videos are not rotated to match the orientation. So, there is a little bit attention to detail that is missing from the software of the Circle 2. Both cameras have motion zones. However, you need to signup for the paid Circle 2 subscription plan to the motion zones. Whereas you get that feature included in the base price of the Arlo Q.

The Arlo Q scheduling software is very impressive and very versatile. There are 5 default modes on the Arlo Q: Armed, Disarmed, Geo Location,Schedule, and Custom. Armed means that any motion or audio will cause a push notification and/or email alert. Disarmed means that motion and audio detection is off. Geo location is when you can arm and disarm the system by location. The custom mode allows you to create specialty modes that may be combination of the built in modes. For instance, I created a new mode that is similar to Armed, but it does not send any type of notification, but still records if motion or audio is detected.

The Schedule mode is the other interesting part of the system. The schedule part allows you to arm the system using any and all of the various modes, built in and custom, and assign them to various times during the day. For instance, if a custom mode is created that record, without any notification, you can set that mode from 8 AM - 11 PM, and then set the Armed mode from 11PM to 7:55 AM during the week. Then on weekends, you can set the Geo location mode all day Saturday, but only from 9AM -12 PM on Sunday and then the Armed mode from 12PM - 9PM. So creating custom modes, and having the ability to set those mode for different hours of the day/week is phenomenal. It makes the system very flexible and extensible. You can't do any of this with the Logitech Circle 2.

The difference between these two cameras are pretty apparent. It depends if you want sophisticated phyiscal mounts for the camera, or sophisticated software. If the physical mounts are most important, then the Circle 2 is the better option. If you want a lot of fine grain software control, then the Arlo Q is the better camera. Right now, I have 3 of the Arlo Q cameras: 1 Arlo Q Plus, and 2 Arlo Q originals. For indoor use, the magnetic mounts are indispensable for my use. I can mount the camera on any metallic surface in any orientation. The fine grain software to control for arming and disarming the camera is also pushed to it's limits in my use case. So for me, I probably won't keep the Logitech Circle 2. if Logitech can implement better software, I think it will have a winner on it's hands. Especially, when the promised Homekit upgrade gets implemented. If a new base, that is magnetized, is also implemented, that would also help mounting the Circle 2 on metallic surfaces.

Update 09-04-2017
When the Logi Circle app wants to use Location Services, it only gives you two choices: Never and Always. There is no "While Using" option. "While Using: should be an option for the user to choose from.

Update 09-08-2017 - Homekit integration
In some respects the Homekit integration is a step backwards from the Circle 2 app. In the Circle 2 app, you can view the feed from any place you have an internet connection. With Homekit, you can only view the feed, remotely, if you have an Apple TV or an iPad, acting as a hub for Homekit. The iDevices company, that makes very good Homekit products, gives remote Homekit access without the need for an Apple TV, or an iPad acting as hub. So, I'm not sure why Logitech can't do the same thing. For Homekit users, if you don't have a Homekit hub, I'm not sure how useful this camera will be to you since you won't be able to view the feed remotely.

Also, when you setup the camera to be Homekti enabled in the Circle 2 app, under the "Smart Home Integrations" link, the Homekit slider appears not to work when you turn it on. It keeps going back to ff. Once you flip the Homekit switch, you need to kill the app and restart it for the change to take place.

Next, when you look at the feed in the IOS home app, it seems like a cropped version of what you get with the Circle 2 app. Again, this seems like a step backwards. Also, sometimes, I can't view the feed in the IOS Home app because it says someone else is viewing the camera feed, which isn't true No one is viewing the feed but me.

Further, Logitech does not allow you to arm and disarm the camera via a Homekit Scene. Therefore, I can't a scene that says arm the camera everyday from 11PM - 6AM every day. The only thing Logitech allows you to do is turn on lights if their motion detector in the camera detects motion. As far as Homekit capabilities, this is all you get, which seems very disappointing. At least give the option to arm and disarm the camera. If Logitech gave the user the ability to arm and disarm the camera, as scenes, then you could also write Homekit Triggers to do the same thing based on geo location. But without this feature, using this as a Homekit camera does not add anything special to Homekit.

Lastly, there doesn't seem to be a way to set the motion sensors sensitivity settings. There is no Low, Mid, High to tell it how much movement it should consider before detecting motion. Also, you can't set the timeout at which the motion sensor no longer senses motion in a room. You can do all of these things with the Elgato Eve Homekit Motion Sensor. So once again, this is a step backward from what is being produced, as a motion sensor, by other companies.

For Homekit, I think you have to buy this camera in the hopes that Logitech will add more useful Homekit, and non-Homekit, features to it. in the future. Because for right now, the only Homekit benefit is seeing the feed in the IOS Home app and turning on lights when the motion detector detects motion. Other than that, there is not much this camera brings to Homekit.

Update 09-11-2017 - Homekit integration II
The Logitech Homekit integration has some strange features. First, if you place the place the camera in Privacy Mode, from the Circle 2 app, the Homekit notifications fail as the motion sensor is turned off. However, if the camera is turned off, from the Circle 2 app, then the motion sensor is stull turned on, therefore, Homekit notifications still work. Also, if the camera is turned off, you can't see the video from the Circle 2 app, but you can see it from the thumbnail in the IOS Home app. But if you double click on the IOS Home feed to see a larger view of the image, then the IOS Home app, on an iPad, tells you that the camera is not responding. But sometimes, I can still see the video when I double click the thumbnail to see the larger video feed. On my iPhone 7, I can always see the video feed, thumbnail and larger video, even if the camera is turned off. The security of seeing the video, when the camera is turned off from the Circle 2 app is very suspect at this time.

Since there is no Homekit Circle 2 app, then you need to use a Homekit app, like Elgato Eve to manage the Circle 2 app. With Elgato Eve, you can turn on and off, the microphone and the speaker. However, you can't turn on and off the video feed from this app. Also, the Circle 2 app allows you to turn on Privacy Mode, which continues streaming, but does not record and send any footage or send alerts. Bu this option cannot be set by Elgato Eve. Smart Alerts is also not available to be configured on IOS.

Turning the camera on and off, as well as Privacy Mode should be Homekit Characteristics that can be used in Homekit scenes. Smart Alerts should be made enabled by Homekit Triggers.

In it's current state, the Homekit features are not very well integrated into Homekit. Therefore, these features are not very useful at the moment.

Update 09-14-2017 - Homekit integration III
Since the current Homekit features in the Circle 2 are not useful, I found that if you plug the Circle 2 camera into this Homekit switch: iDevices Switch - WiFi Smart Plug w/ Energy Monitoring, No Hub Required, Works with Amazon Alexa , then you can achieve some real Homekit features. Since the Circle 2 will boot up when power is applied to it, you can use this iDevices switch as bridge to Homekit. Meaning, I found that I can create an Armed Camera Homekit scene that just turns on the switch, and a Disarm Camera scene that just turns off the switch. Thus, now, I can create geo location triggers that urn on the camera when I leave the house and turns the camera off when I arrive home.

The other benefit to using the iDevices switch as a bridge to Homekit, is that I can fully cut power to the camera anytime I want,. Since turning off the camera, in the circle 2 app, does not really affect the Homekit stream, and there seems to be no way to turn off the video stream in Homekit., then using this Homekit switch fixes that issue for the moment, until Logitech can provide a true solution.

Further, I can now schedule the camera to turn on and off, by specific times of the day by using the extensive schedule feature in the iDevices app. The schedule for the iDevices switch is stored directly on the switch. Therefore, no Apple TV is needed to store the schedule on a hub.

iDevices also provides remote connectivity, without an Apple TV. So, the camera connected to the switch can be turned on and off remotely as well. To turn the lights on, via motion, I use an Elgato Eve motion dectector. The Circle 2 Alexa skill can turn on the camera, but can't turn it off. With the iDevices switch, I can have Alexa turn off the camera as well. With these additional devices from iDevices and Elgato, then a "good enough" system can be put together since the current Homekit features of the Circle 2 are cannot do any of this right now.

Lastly, I would not recommend to use this camera outside. The camera is not locked onto the mount, that was shipped with it, in any secure way. Thus, the camera can be easily removed form the mount and be stolen.

Update 09-21-2017 - Homekit integration IV
If you have Homekit enabled in this camera, and you have a Homekit enabled lock, in my case I have a Schlage Sense lock, when the motion detector detects motion, Homekit will send a notification, with a snapshot of an image the caused the motion, and a button to unlock the door. In my case, the Circe 2 and the Schrage lock are in the same Homekit room. Not sure if the unlock button will show up if the Homekit Lock is not in the same room.

For IOS 11, you can restrict notifications, with geo location, to when you are not home or if you are home. So, for instance, you can tell Homekit to send you notifications if you are not home. If you are home, then you may not want all those notifications coming to your phone. On IOS 11, notifications can also be restricted by time. Therefore, can tell Homekit to send you camera motion notifications between time 11PM - 8AM and not during the day. Time and geo location restrictions can also be combined. IOS 11 makes this camera more useful than before. However, this feature can only be access by 3D pressing on the device that supports notifications and enabling it there. It can't be accessed through Homekit triggers, so it can't be combined with other conditions, therefore, it's not as flexible as it could be.

Setup was amazingly easy. Just ran the app, it found the camera, updated the firmware and was good to go.
I setup using the Circle 2 Windows Mount. Attaching was easy and stable.
Daytime picture quality is good.
Night time I get a little more reflection of the camera in the image than I hoped for, but it isn't terrible. Really the only negative and it isn't too bad.
Maybe something that they can optimize with more use. Note: make sure you use the Window mount setting, if not you will just get 100% reflection at night.
The app is easy to use, detection of motion and people is right on and I like the way it creates the alerts/clips.
All in all, I'm pretty pleased and would recommend to others.

Update: The web app is bad. Guess they are getting hit with a lot of traffic now and don't have the right infrastructure setup. Watching a video streamed does not work at all, just shows 1 frame and that's about it. If you want to actually see the video you have to download it. Needs a fix fast.

Update:. The playback was fixed a long time ago,. I just forgot to update. Upping 1 star. Nught vision thru window can still be a little better.
