User questions & answers

Question:	can i use this and watch on my desktop computer
Answer:	This is the main thing I don't like about Ring Pro, they have not bothered to make it work with live view for Windows 7. This tells me that like many companies they don't care or bother to make their products backward compatible. If you decided to upgrade to Windows 10 despite all negative pushy attempts to force it upon us by Microsoft, you are in the Live View club. If you choose to stick with Windows 7 and wait until Windows 10 OS issues are resolved before upgrading or buying a new system, your out of luck. Thanks, Ring! I feel like you truly care about all customer's needs.
Question:	Do you have to pay for cloud service
Answer:	there are some other products that you don't have to pay for cloud service but they do not have the analytics and features of this product... all the brains of what this devices does are in the cloud

User questions & answers

Question:	Can you have 2 ring doorbells on a home? will they operate independently
Answer:	Yes as long as you name them different should work fine
Question:	can you hook the feed to a hard drive
Answer:	I don't believe there is a continuous "feed." The device is activated by motion and/or pushing the button, then recordings are made. If it helps, the videos can be shared with several options. I share it to myself by email then I capture it with software I have for capturing videos on my desktop. Then I save my videos to an external hard drive for backup.
Question:	The echo show5 has no built-in battery? Seems that I need to buy a ggmm es5 battery base to move my echo show around
Answer:	Why are you asking about the Echo Show on a Ring Doorbell 3 product listing? Also, no Echo device has ever been battery powered, seems strange you wouldn't know that. Many third party manufacturers make external battery packs for them, but the reliability of them is questionable.
Question:	What is Pre-Roll on the
Answer:	Hello, The Pre-Roll feature is available on the Ring Video Doorbell 3 Plus. This feature allows you to see an additional four seconds of video before the motion event was even triggered. This is a first-to-market feature for battery-powered doorbells and unique exclusively to Ring. Pre-Roll video is in black and white and in low resolution to conserve battery life.

Question:	Can i record video to a nas rather than use the cloud storage with monthly charges

Answer:	I have 3 receivers; 2nd floor, main level and basement. All work perfectly and loud enough to hear everywhere in the house!
Question:	Can i use any poe switch to power the ring elite or do i have to use the poe injector it comes with
Answer:	Absolutely...the selection of tones are very loud! But Suggest putting a second receiver around where you normally sit.
Question:	Why pay double for ring elite, pay for installation of poe ethernet wire? isn't ring pro with wifi good enough? anything i am missing something
Answer:	On my units, to change the transmitter batteries you have to pop the back off the unit, undo two screws to remove the circuit board from the case, change the battery, then remount the circuit board in the case, then put the back on.

User questions & answers

Question:	Is there lifetime warranty if it gets stolen or broken
Answer:	Ring gives you lifetime protection against theft. If someone steals the camera, get a police report and Ring will replace it for free. A one year warranty is included when you buy the camera. If you subscribe to the Ring Protect Plus Plan within the original one year warranty period, Ring will give you a lifetime warranty for as long as you keep your Ring Protect Plus subscription active. A subscription to Ring Protect Plus is currently $10/mo or $100/year.
Question:	what is the range of motion sensor
Answer:	They shortened the range with an update in Sept 2019. We are lucky to get more than 10 feet out of it, and by the time the Ring is activated and alerts us the person is already at the door. We are fighting for them to change back for removing an advertised feature or full refund.

User questions & answers

Question:	Can the unit be hung from the ceiling with corrected orientation
Answer:	Can this unit be placed/hung facing outside the window?
Question:	Is it possible to store captures locally to a NAS
Answer:	You can store them to NAS not directly though. You need to purchase their plan either $3/month per camera or $10/month for unlimited cameras. If you have either plan you can download them from the cloud and store them on your NAS. I don’t know what Amazon Stockholder was talking about as it was stated that you can access, DOWNLOAD, and share past Ring videos. Also Amazon Stockholder would be completely incorrect with his reply.
Question:	Does it require any sort of subscription
Answer:	Can i just purchase Ring Indoor Cam and don't have subscription
Question:	Can you download the app on a tablet or desktop? Must you only use a cellphone
Answer:	Same discovery as Howard stated above. The current software in these cams, it doesn't not appear on my Windows 10 Ring app on my computer. It appears fine on my Android phone, but I pretty much do everything on my computer. I'm at work at home Cybersecurity engineer, so I like to see everything on my computer. I have 2 spotlight cams (over garage and one over the backyard) 2 of these indoor cams in my house (1st floor) and the Ring doorbell. I can see everything but the indoor cams that cover my 1st floor of the house. I have read via threads and forums though that the software is going to update this year sometime and they will eventually appear in the Windows 10 app on your computer systems, so that is a plus. The Ring devices check for updates themselves over your wifi network, so I'm assuming they will update themselves at one point and they will appear on my Windows 10 app one day soon. I'm hoping...it's one of the main reasons I got these. I want to be able to monitor and check on my three dogs on the first floor of the house, while I'm working in my office on the second floor.

User questions & answers

Question:	My family has two appartments next to each other, both separate electrical installations. Would this work if we wanted to split the internet bill
Answer:	Yes the EX8000 used as a wifi extender you have the option of having a guest network. You can use same SSID name as your main router or use a different SSID altogether. I did have issues with more than one extender on the same network using same SSID name as main router so I had to change one of the extenders to a different SSID.
Question:	Has anyone connected a ps4 of xbox one to the wifi from the range extender? if so, signal and game play any good
Answer:	If you mean an AT&T router signal, yes. If you mean cell tower signal, then no.
Question:	Does it create a new sid or does it exteneded your current sid, so one does not have to switch to differing networks when in range
Answer:	the input voltage is from 100 to 240 volts
Question:	I don't understand how some people give this 4-5 stars and others can't get it to work and give it 1 star
Answer:	there are 4 ports. I use multiple ones as this is the only system I can find that does not change the network name but once a year I also have one break and have to replace it or hard reset it myself.

User questions & answers

Question:	Will this be using the same batteries as the older models

Answer:	It does not support 220v, but we will be launching a new version soon that will. Stay tuned.

User questions & answers

Question:	Are you able to turn off the spotlight and just use the infrared
Answer:	Yes
Question:	Can the cable pass through the top of the window? I have a nest like that now as the power cable is flat
Answer:	The 20' long cable is round, about the thickness of a standard ball point pen (about 7/16 inch or 1 cm), and the plug at the end is just as one would get on a power tool or heavy duty extension cord. If you were to open your window, pass the plug and cord through, then try to close the window down on the cord, there would be a definite GAP where air/rain would come through. I would NOT recommend this. If possible, you may consider running the cord up your exterior wall to your roof soffit, and power it through your attic. You can use an extension cord on it as well, just make sure it's not accessible to anyone who would want to disable your cameras. I have learned that the RING app does NOT inform you if power has been lost the camera, so the burglar could just unplug it, rob you, and you'd not know until you checked the camera feed or came home.... If you're plugging it into an exterior outlet within reach of bag guys, consider replacing the outlet cover with a locking one so they can't unplug it.
Question:	will ggmm es5 battery base help if I want to use my show5 when unplugged
Answer:	of course, that is exactly why I bought it
Question:	How long do the batteries last
Answer:	I installed mine May 26th above the garage of our new house. Checking live view a couple times a day and having the motion on 24/7, the battery died on June 15th. Three full weeks with heavy use. I just recharged the battery plus added a second one. I’ll give an update on how long these last.

User questions & answers

Question:	How does it fasten to the front of the house? It is expensive, so can someone easily rip it off
Answer:	Hi Neighbor, Ring doorbells are screwed into a mounting bracket and anchored to the wall so it can’t be easily removed. If it does get stolen, the doorbell will capture a video of the incident, which you can use to file a police report and we will replace it for you free of charge. If you have any additional questions, please reach out to me directly at [email protected] today! ' Thank you, Mary Nell J., Neighbor Satisfaction Specialist [email protected]
Question:	Can the quick release battery be taken out by someone who wants to rob the house
Answer:	I have it, and it's fast for detection so I have no worries for the average person (90%) who is going to rob you they WILL be seen and recorded...but a "smart" robber will have a 25 dollar wifi jammer to disrupt your network and your neighbors to get past it..but then you pair it with the ring alarm and as long as the cell signal is not jammed an alert should go off. I had a relo link camera, budget and with an SD card but it ate batteries and sometimes not record every event. This is a great device if you want easy and convince...but the best devices are expensive and wired only with a battery backup.
Question:	is It weather or waterproof
Answer:	I found out that yes, it most definitely is weather and waterproof, but in not so smart of away. I had my ring video doorbell 2 in its place by the door when hurricane Irma came through last year, and forgot that the doorbell was there until about 4 hours into the worst of the northeastern bands with the steady high winds and hang reason blowing sideways... which were blowing to the east - right at the front of our house. So at the point where I realized the doorbell was still outside, our power and internet were out but the battery was still powering the doorbell and I was worried about the internal electronics, but I took it inside, too out the battery, and put it on the counter and forgot about it for a few days until things started to settle down, and then the power finally came back on. so at that point, it was the Moment of Truth when I went and put the doorbell back in its place and when it reestablished its connection with the internet, every aspect of the doorbell worked just fine. It's been a year now since Hurricane Irma passed through Florida, and all the functions of the doorbell are still working just fine: the battery longevity, the speakers, the microphone, the infrared lights, and the camera lens are all fine. One other important thing to mention: our front door faces west and is right near the corner of the wall to the garage, which faces south. So, it goes without saying that it can handle the worst of Florida's relentless sun and humidity through the summer like a champ!!
Question:	I'm surprised that no-one has asked the question I'm about to ask.... Do you have to "Subscribe" to their service in order for it to continue working
Answer:	I'm surprised no one has asked about the apparent need for a home WiFi subscription being required along with the $100/year subscription needed for the doorbell itself. And what if you have a front AND backdoor?? Do you pay for WiFi and EACH doorbell every month? And how secure is the mounting? What's to prevent people from just walking up and stealing the $200 doorbell itself, along with any packages they may find on the stoop?

• Convenient power to help charge and extend the battery life of your Ring Video Doorbell (2020 release).

User questions & answers

Question:	So how well does this work? The sun hits the front of my house all day but id hate to get it if it dont work good
Answer:	I have one in the back yard, no roof in that area. It’s been plugged in for about 7-8 days and still at 100%
Question:	I have a roof over my front porch so I don't get direct sunlight will it still charge
Answer:	My camera is on the front porch, under the eve but the solar panel is just up above on the porch roof where it gets full sun so it never runs out of power. Not for 2 years.
Question:	Can gen 1 ring work on gen 2 solar panel
Answer:	No. The mounting bracket on the Gen 2 provides enough space for the solar charger to plug into the back of the Ring. This doesn’t apply for Gen 1 Ring devices. I had to buy a new Ring since I didn’t see the fine print.
Question:	How much sun does this actually need? My front door only gets direct sun for about 5-6 hours a day, in the morning
Answer:	We have this same ring set up for 6 months and the solar panel has received direct sunlight for 6-8 a day and has not charged the unit. As we have moved into shorter days and less sunlight I can only depend on my Ring door bell for 3 weeks then I must remove it and charge it for 24 hours. I wish I had returned the solar panels.

Product features

Arlo Smart Home Indoor/ Outdoor HD Security Camera

The Arlo camera is a 100 Percent Wire-Free, completely wireless, HD smart home security camera – so you can get exactly the shot you need – inside or out. The Arlo camera is weather-resistant and includes motion detection, night vision, and apps. It can capture clips and send you alerts whether you’re at home or away for round-the-clock peace of mind.

Service is included

F.A.Q

• Keep active locations in the camera's field of view. Your Arlo camera has a 110-degree viewing angle. Position your camera so that the space that you want to monitor is within the camera's field of view.
• Elevate your camera. Mount your Arlo motion-detection camera at least 7 feet (2.1 meters) above the floor and aim it slightly downward for the best sensor performance.
• Ensure that side-to-side traffic crosses Arlo's field of view. Arlo's motion sensor is much more sensitive to side-to-side movement across its field of view than to movement directly toward or away from the camera. The best area for motion detection is 5 feet to 20 feet (1.5 to 6 meters) from the camera position.

How can I extend the range of my Arlo system?

Instead of connecting the Arlo base station directly to your router, you can connect the base station to an Ethernet port on a Wi-Fi range extender or Powerline adapter. This means you can put the Arlo base station farther away from the router or in a central location in your home to get better coverage with your Arlo cameras.

Does motion detection work through glass or windows?

Motion detection does not work through windows reliably. Arlo cameras use motion detection technology that is inhibited by glass, especially windows. Passive infrared, the type of motion detection used by Arlo Wire-Free cameras, detects changes in heat. Most glass used in homes today is insulated, limiting the movement of heat through the glass.
