Just installed a Reolink security camera on the dock. $300 from Amazon. No WiFi out there so I went with cellular. $20/mo from T-Mobile.
IR night vision, motion detection, alarm, speaker, pan and tilt. Sends real time notices to my IPhone.

How timely...as I just had a surfboard stolen off my back deck (attached to my dock).
I DO have wifi available and was looking at Nest and Ring brands...any suggestions from your (or others on the Forum) experience/research?

For the house I used the Arlo Pro 4 cameras. $450 for 3 from BestBuy. These are WiFi. The kit comes with 4 batteries. They’ll last from 2-4 weeks and are easy to change out. No wires to run.
Motion detectors, they can identify a person, animal or vehicle. Record to the cloud. Notices sent to my iPhone.

If you have power on your dock, I'd suggest Wyze.
Either the v3, or this floodlight and an additional v3.

I use Ring, flawless in my opinion

Which one works with T-mobile? I want one!

I have the Wyze at home. They work well. Typically have to charge the batteries every 2-3 months

I took the easy simple cheap Blink route at home, lake, and dock.
Once I added mesh router that let wifi stretch out it was so easy a cavemen (and me too)could do it

Reolink works with T Mobile

I run 10 Wyze v3s outside my house, and 3 inside LOVE, LOVE, LOVE them.

I reused the 12v wiring I had from my previous camera install to power them.

here's a parts list I used.
