Title says all, but would like to include ... temp and voltages and a bilge alarm, may be
24v camera and router recommendations, please

Noticeable lack of replies.
24v almost certainly an issue here. Not impossible but may be narrowing choices.
Router? So 4G/5G...? What do you want! If you a throwing cash around a RUTX12 would sort you woth dual SIM cards for better coverage, GPS positioning, WiFi and Ethernet network into which you can plug any other stuff. It's also rediculous overkill unless you are running a small ferry. But it is 9-30V
I think it can also take a single data point (like a relay to set an alarm status) which it can then process - although I've never used that feature. Some of their others might do a variable voltage which could be why you want but generally I think people RasPi these things and send as data... ...which the. Begs the question if you need a router or a RasPi mobile hat
Pi uses 5V usb - so you'd need a USB 24v power supply...
How off the shelf are you aiming?

a lot of devices are USB powered (5V) so all you need it one of these for each. They can cope with 8 to 32volt input and are available with any of the USB plug types.

I would like off shelf if possible, suppose must be at least 4 g as 3g is being closed down... Perhaps should use mains and an inverter?

All Ubiqiti network stuff is 24V - I have no idea about 4g access points though

Teltonika routers all work on 9-30v dc direct, you can find many second hand as well. We use RUT950 as it takes 2 sims and external antennas very easily

If you step up to 48V the Teltonika TS100 does PoE which could power quite a few types of camera.
The Teltonika routers are great but aren't very fast compared to consumer devices which use more channels - most of the Teltonika kit is cat 4 LTE with some of their newer ones being cat 6 LTE. This means they top out at 150Mbps and 300Mbps respectively if they have the bandwidth to themselves (which they won't!). Huawei make a cat 19 LTE router capable of 1.5Gbps - this will spread the traffic over more channels and stands more chance of getting higher bandwidth. My RUT240 was fine for streaming video down, but not sure I'd want to stream multiple cameras up to the Internet with it.
The Victron Cerbo (or Raspberry Pi with Venus OS) is probably the easiest way to get boat data up, it can hook into CAN and NMEA as well as tank senders etc.

What so you want the camera for? Security type thing?
We have a couple of Amazon Blink cameras on the boat. They are powered by AA batteries that last for months. One is fitted on deck and frequently subjected to green water and has shown no issues. They are wireless, paired to a small hub box that is in turn connected to our 4g Mifi making it viewable from anywhere.

Yip. We can either find you a solution for under £60, or under £6000... Or anywhere in between...
...we could really do with a description of what the intended output is

3G would be borderline dodgy for video speed anyways.
But where are you using it!? Do you have signal?
Why would an inverter be on the list!
If the use case is in marina when plugged into the mains, fine, mains will work. But if it needs to work on a mooring or anchorage then you are wasting power going from 12V (24V is just two 12V batteries in series) to 240V and back down to whatever it runs on.

Which is probably still faster than the 4G connection can handle (can't be many boat places with 5G at the moment). So unless there is a load of local network traffic before the 4G that will be your limit.
I can stream remarkably well from a RUT12 - I'd not but one new...
I'm not sure this is off the shelf enough...
...but it WOULD be my potential solution. I'm out of touch with Pi OS... There was a sailing specific one too

4G headline speeds assume using all available channels in empty cells. Each channel is a fraction of the bandwidth and your connection is multiplexed over them, the number you can use depends on the category of your device. A cat4 device is probably similar to 3G in total available bandwidth, but again assumes you're using empty cells, which you won't be because more people have more devices than ever before. The design behind LTE is mostly that additional speed can be gained through expanding the bandwith that's usable, but this requires that the receiver can utilise that additional bandwith.
Long story short - the maximum real world throughput on these is a lot lower than you'd expect, topping out at about 30Mbps on a good day. That's not necessarily a bad thing, but they do also suffer in busy areas because they are limited to a subset of the channels.
