We'll be on the Sapphire in a couple of weeks, and I'll definitely be asking just to see if my previous wi-fi router assumption is correct. That's the only explanation I can come up with, as I do a lot of posting to CC while on our balcony with the door closed and I always have the same wi-fi reception whether I'm inside or outside. 1 Link to comment Share on other sites More sharing options...
Rare Crashe Posted January 7 #28 Share Posted January 7 Google picture search shows a few similar devices. Heat detectors…which would make sense over balconies. 2 Link to comment Share on other sites More sharing options...

After the Star Princess Fire in 2006, Princess equipped all balconies with Sprinkler - fleetwide. You think they added heat detectors in 2018?

Yes, please ask an engineering officer. I really want to know it, too. 2 Link to comment Share on other sites More sharing options...
Rare DHP1 Posted January 7 #31 Share Posted January 7 (edited) Balcony camera?? - Princess Cruises - Cruise Critic Community Fire/Heat/smoke sensor. These were added after the Star Princess fire. Edited January 7 by DHP1 Link to comment Share on other sites More sharing options...

Rare Rick&Jeannie Posted January 7 #33 Share Posted January 7 (edited) Curious and following! Although I *really* don't think they have anything to do with wifi...because that would be an absolute "waste" of coverage being located on the edge of the balcony like that. The wifi access point located in the cabin itself will *easily* cover the balcony. A pane of sliding door glass will NOT hamper a radio signal. Plus...the "covers" appear to be all metal...which would inhibit a signal. Edited January 7 by Rick&Jeannie 4 Link to comment Share on other sites More sharing options...

As I wrote before, the WiFi signal was extremely bad on the balconies. Example 2017 on the Crown. I always had to go inside to send a plain text Whatsapp message. lol. Since theses "things" appeared, outside WiFi got much better. MedallionNet installation. Still my 1st guess. Edited January 7 by EDVM96 Link to comment Share on other sites More sharing options...

Plus...the "covers" appear to be all metal...which would inhibit a signal. Good points. The only reason I originally thought it might be a wi-fi router was because when I was on one of those E-class ships on another cruise line while sitting on one of their sky suite balconies, I got zero wi-fi reception when the sliding glass door was closed. But when I cracked the door open to get access to the wi-fi, the AC in the cabin would shut off. Not good when you're in the Caribbean and your DW is inside trying to stay cool. Then when we recently went on the CB and then the Regal and got great reception on the balcony with the door closed, I just "assumed" that "round box" was the reason. But after reading the above link provided by @DHP1, I'm now leaning more towards the fire/heat/smoke detector theory. But when we're on the Sapphire in a couple of weeks, I'll ask the question, if for no other reason than to quell my curiosity.

Potstech Posted January 7 #37 Share Posted January 7 My guess, just as good as any other, is a alarm sound annunciator in case of emergencies like crash or abandon ship. Next guess. Link to comment Share on other sites More sharing options...

Next guess. I agree with you. Most likely a buzzer type or horn type. I will pay attention at the muster station training and see if an alarm will sound to report to your muster station in a real emergency. I know the captain will verbally announce, but that intercom system will not notify all. I think there is different alarm sequences for different type of emergencies. I am sure they test the alarm system often, probably on sea days . Link to comment Share on other sites More sharing options...

hcps-osullivax Posted January 8 #42 Share Posted January 8 Those are either emergency lights to flood the ship in the event of a situation, or heat sensors monitoring for fire. I don't know the timing as to when those were added, but they are not wifi related, medallion related, or a camera. The boost in wifi coverage out to the balconies is due to the in-room wifi router. When each ship was updated with Medallion technology, the new tvs that went in place are hiding a small wifi router behind them. This is the major boost of connectivity we've noticed since 2018/2019. Prior to that, the routers were only in the hallways and would struggle getting a signal through the heavy metal/fire proof cabin door. In addition to the in-room routers, there are medallion sensors overhead in the bathroom, cabins, and balcony. But the one on the balcony is a lot smaller than this emergency light dome, and fully enclosed in opaque plastic (and all medallion wiring is purple too if you haven't noticed). Again, not sure if its for additional emergency lighting or for fire monitoring (since the Star Princess incident in 2006), but I can confirm its not a camera, medallion sensor, or wireless access point. 3 2 Link to comment Share on other sites More sharing options...

Thanks for clearing this all up. I knew there had to be a Wi-Fi router (sensor) of sorts on the balcony. The service on the balcony was just too good for there not to be one. 😁 Link to comment Share on other sites More sharing options...

Are these really routers or just access points. I can't see the reason to put a router in each room, that not how wireless networks work. You would want either Access Points or Extenders in various locations, but unless each room is its own network (sub-net), you would not need routers. 2 Link to comment Share on other sites More sharing options...
Papa Yoda Posted January 8 #48 Share Posted January 8 Right, not routers or repeaters. Cisco Aironet Access Points are in some cabins (suites especially - behind the TV) and on the ceilings of passageways. As noted they are white boxes some with a blue light on (hopefully). They home back to ethernet switches in the electrical closets. There are none on cabin balconies. 3 1 Link to comment Share on other sites More sharing options...
TRLD Posted January 8 #49 Share Posted January 8 (edited) I suspect they are part of the external fire protection system. While not an exact match I found this picture as part of an article describing the changes Princess made after the ship fire. Note the person pointing to both the sprinkler head and the detector that looks pretty similar to the picture mounted in a similar location. I think this picture was of the implementation on the Star Princess. Edited January 8 by TRLD 3 Link to comment Share on other sites More sharing options...
chengkp75 Posted January 8 #50 Share Posted January 8 (edited) Infrared flame detector. Due to the wind on balconies, smoke and heat detectors don't work too well, so they go with the flame detectors. The sprinkler head provides heat detection, as the thermal bulb blows out at around 135*F. And, if you look closely enough, the photo above is of the exact same sensor as the OP's photo.
