Gosh, I wish I had a back window! I'm jealous. Even steering from the fly bridge I can't see the back in very tight quarters.

We have plenty of space so a separate display would work fine. Our chart plotter is an older Netnav system with the infamous iPad backup. I guess we could run the cameras thru one or the other but the screens get busy.
Thank you!

We just replaced our wired back up camera on a tanker at work with a new wireless unit. The old wired camera was from the same company and work great for over 12 years until the outside wire connectors actually fell off from corrosion(nasty stuff in the tanker). So far the operators of the tanker love the new camera and monitor, although the suction cup mount for the monitor is a little to weak for my liking and I would go with their other mount option in the future. The camera seems very heavy and well made and comes with night vision. This new 7" monitor even allows for two side view cameras to hook up to it, although the side cameras would be wired and you would need to change screens to view them. The company does have larger quad view monitors. We purchased it on line at

When I was in China about a year and half ago I rode in a Buick minivan that apparently used cameras to provide a synthesized top down 360 view all around the vehicle. On the screen in the dash (also used for the backup view) there was this top down view full time that showed all the things going on around the vehicle. The view had to have been from multiple wide angle cameras. The image was combined and the distortions corrected such that it looked like the camera was mounted about 10' directly above the vehicle looking straight down. If it is cheap and easy enough to put in a minivan, it should be able to be used on a boat. Certainly might be handy.

ssobol,

Many newer cars have them here (sadly mine is too old). They can be bought on Amazon and retro fitted. From what I understand it is often good but not perfect and calibration is key. I keep looking at them, but thinking that (on my car) it isn't worth the install.

I'm not sure if they are set up to work with something the size of a large boat, i.e. if the cameras can get enough of a view and if the algorithms will be able to knit the images together.

Some examples from Amazon (there are many more):

Interesting technology.....

Would be just great to have a two camera system, one on each rear corner.

In the boat or in the car?

If in the boat i'd love to see pics of the install.

I have a car with the 360ļ overhead view functionality. It's handy in a few situations, like getting centered in a tight parking space, or a not too close to a curb. It's really clever to see the lines arc when the wheel angle is changed in the backup view, nice integration with the rest of the vehicle network to get that.

But honestly it's a bit more of a distraction than an actual aid. There's too many mental spatial transitions you need to go through to keep tabs on just what it is you're seeing in the display. I'm sure some folks handle this better than others but I've found it's better to park without it, and now mainly use it to just check for final alignment.

Still, it'd be a clever experiment to see how well one of those would work on a boat. There's a few examples online.



The music is annoying, but this shows the calibrating:



I'd think you'd have to calibrate it while on the hard with the calibration boxes and lines set up at the waterline.

The hard part would be placement of the rear camera. Most automotive systems are going to have the camera at the very rear of the vehicle. That's not always going to be practical with a boat with swim platforms and such. I know it wouldn't work on mine. I don't know how well the calibration would deal with being in a more forward position. I'm sure it "could be" overcome but probably not with the generic kinds of systems intended for cars.

I'm guessing a system intended for a bus or truck might be at least a little more amenable to working on a boat.

3D 1080P 360 Around view car camera system for bus

https://www.amazon.com/dp/B07H5KJ8L4/

Seeing hardware devices doing the interpolation from spherical to flat in real time is impressive, especially for such low price points.

It's pretty neat what 360 or spherical view cameras can do. I've got a small Ricoh Theta that's great at taking 360 videos. The hard part is posting or sharing them as few systems out there will re-play the 360 videos.

I was just going to post a Boat US article about the same thing. This one has a video that's a bit hokey.

https://www.boatus.com/magazine/2019...nse-system.asp

Lots of things have to be integrated to make that work. The common element in most demos thus far seems to be IPS pod drives. They're nice but not without their costs compared to traditional outdrives or shaft props. S

Interesting topic.


Besides ease of installation, is there any performance differences between wired and wireless systems?

I have the same problem on our Golden Star 37 trawler: there's no aft viability from the lower helm and you can't easily see the side of the dock from the upper helm.

I've a 2010 Raymarine MFD and a camera can be matched to it via Ethernet cable, but my preference would be Bluetooth or Wi-Fi camera connection with an Iphone, Ipad and/or Windows computer. With the exception so far of radar display, all three devices have apps for everything else I can do on the Raymarine and the Raymarine is becoming my least favorite chart plotter option.

Any Bluetooth or Wi-Fi camera suggestions?

We just bought this:

Mostly for engine room surveillance underway, but will install at least one camera outside facing aft.

I went through this last year and landed on a GoPro broadcasting to my Ipad. Its wireless (bluetooth), does not require wiring for power (both have batteries), and you can record for post docking review. Also, I already owned both, so cost = $0.

I also have an issue with visuals off the stern. I added a back up camera from advanced auto parts. Itís wireless. Supplied 12v power from stern nav light and power for the display at the helm by using a 12 v cigarette adapter. Simple, cheap and effective. Only disadvantage is the size of the display, but itís adaquate.
