Batman: My wireless camera has been on for 1-2 months and its showing 92%. Madness. I didn't even charge it, it's out of the box.

But that’ll only be recording triggered events, not 24/7 recording. It’ll also depend on how many events it is recording, and that’ll be heavily affected by how the particular space is used. One of ours covers much of the front lawn; my son practices volleyball on that every day, so we get heaps of recordings which in turn reduces battery life. 

Also, given the lack of constant recording, I’ve set our wireless cameras to a low cool-down period, to maximise the chance of them picking up related movement. 

Next time I’d look to solar-powered options that provide for 24/7 recording or at least decently long event recordings, or go to the hassle of putting in permanent wiring.

So I recently replaced all of my Ali Express system (due to EOL of Flash among other things) with an Alro Ultra system. The Good thing about the Arlo is the quality of the video is exceptional, remote units can be Solar powered (for cameras that are not heavily used). They will do everything the OP has asked for but there are a few caviots. The first one is this system is expensive, its ended up costing a lot more than I expected. The second one is the central hub runs its own wifi to the cameras, I had to re-locate mine to the center of the house (with ethernet back to the internet router) to get consistent camera reliability. Recordings go to both the hub (Micro-sd card) and to the subscription cloud service. You can choose to have 24x7 streaming to the cloud service for $10/month/camera if you want, but the movement detection is very good. If you have a very heavily used camera (I have one that gets every car going past the house) then the solar won't cut it and the power will need to be cabled. There are also hidden/camo ones that can use wifi or 4g that go straight to the cloud if desired. Detection can be via movement and or sound and the mobile app always has access to the cameras. Two way voice works but I find there is a few seconds delay, its fun to confuse the cat with though.

We installed Hikvision 6Mp cameras as part of the security in the new house.

So far, set and forget with excellent IQ and a good app.

@Geektastic...appreciate your post was a few months back, but I was interested in the model you installed and supporting NVR? I have been looking at the following as a replacement for my aging dahuas

Buy the HiLook IPC-T280H-MU 8MP/H.265+ Indoor/Outdoor Turret PoE IP Camera,... ( IPC-T280H-MU ) online - PBTech.co.nz

We fitted the cameras that have the model number DS-2CD2365G1-I

The NVR is a 4 channel Hikvision; we fitted three cameras on the house and left the fourth channel for the one that will go at the gate when I put the security gate in.

I'll second Hikvision as good cameras.
We've replaced our older Dahua bullets with them and are completely happy with the results. In Canada but I'm pretty sure they're the same cameras available in NZ.

We've got 4 X Domes.. DS-2CD2143G0-I's  three 4mm's and one wider 2.8mm for overlapping Fields Of View sides and back, and 2 X DS-2CD2385G1-I turrets - 2.8mm and 4mm facing the front.

We initially started out with a couple of the domes running individually to see if we liked them.

With 128GB microSD cards in them they worked fine as stand-alone cameras - so if someone wants just a one camera set up that's easy to do.
They're PoE powered, wired cameras so we powered them with some spare Unifi injectors we had laying around.
Super easy to install - they came with a template for drilling holes, loosen a couple of screws to adjust the camera angles - the hardest part was feeding the cabling through the ceiling space and eaves.

We downloaded Hik's SADP app to find and set up the cameras - they have an easy to understand interface, things like formatting the card, or setting areas for motion detection to avoid is pretty simple.
No problems with the transition at dusk to IR which we've had with other cameras, and found the night iR range and quality pretty good.

Once we decided to buy more cameras we bought a DS-7608NI-Q2/8 NVR and popped a couple of WD Purple HDDs in it, also set up a dedicated UPS to run it - as I'm pretty sure a power cut won't be good for continuously recording discs.

We've had the 6 PoE cameras running solidly on it now for over 6 months and about to add a DS-2CD2563G0-IS mini dome at the front door.
And whenever I get the time to mess with it I find something else useful to set up.. face recognition, tripwires..
