Here is the Scenario - Manual Gate about 600m away from the house. The gate is surrounded by trees and not clearly visible from the house, but there is the option for a WiFi Link as there is a bit of line of sight from the house. No power available at said gate.
Thinking of a solution is linking into a Reolink Camera Network. More cameras around the house. So trying to keep clear of Solar WiFi Camera Solutions from Ring etc. PtP Link from House to Pole at Gate into a POE Switch with a Reolink PTZ Camera on it. That is relatively straightforward. The issue is power. PTZ Camera to allow flexibility of movement rather than a fixed camera.
I was thinking of a custom-made solution involving a 100Ah Lithium LiFePo4 Battery with a smaller inverter (maybe 1000W max?) that is charged via a Solar Panel (with required MMPT). Again, this only needs to run a PtP Link and a POE PTZ Camera (both could work off individual injectors rather than a POE switch).
An alternative solution is to find a power box like this for example(itechworld.com.au) that can run and also have a solar panel charge.
Also, for those who are good at maths and electrical calculations, my understanding is that for every 100Ah your battery system is, you need double that in Solar Power for Charging. So 100Ah = 200w Solar Panel, 200Ah = 400w Solar, etc.
Are there any other ideas/solutions or out-of-the-box solutions?
All of course into a security/lockable cabinet fixed to the ground or something to avoid tampering.
Please Note - 4G/5G Solutions are not an option due to little/no/poor phone coverage
You are massively over specifying the power draw. These types of cameras use in the order of 1 or 2 amp/hour a day.
