Who actually needs a 4G camera

A 4G solar camera is a battery camera with a mobile modem and a SIM slot instead of Wi-Fi, plus a small solar panel to keep the battery topped up. It doesn't need a power point or your home network. That makes it the right tool for places that have neither: a farm gate, a shed at the back of a block, a building site, a boat shed or a holiday house that sits empty for months.

If the camera's going on your house and your Wi-Fi reaches the spot, I'd usually skip 4G. A Wi-Fi battery camera costs less, needs no data plan, and a wired camera system with a recorder is better again for a home you live in, because it records around the clock and nothing depends on a battery. The 4G camera earns its price where the alternative is no camera at all, or a long trench for a cable.

I've picked five here from $189 to $369 at time of writing, all sold new on Amazon AU, and every one ships with a solar panel in the box. Three are Reolink kits sold by Reolink's Australian store, and two are Tapo kits from TP-Link sold by Amazon AU. Four of the five can pan and tilt, so one camera can watch a gate, a driveway and a yard rather than one fixed view.

I left out the trail and game cameras that came up in the same search, because they're built for wildlife triggers rather than watching property, and the 4G cameras with no solar panel in the kit. I also dropped an EZVIZ 4G kit whose listing text named UK carriers, which usually means a listing written for another market. That's the kind of thing worth checking on any 4G camera, since the modem has to suit Australian networks.

The SIM and the data plan

This is the part that catches people. The camera needs a working SIM with data, and that's a running cost for as long as the camera's on the post. The Altas Go PT and Go Ultra kits include a SIM card, and Reolink's SIMs are activated, topped up and tracked through the Reolink app. The Go PT Plus listing doesn't say whether one's in the box. The Altas Go PT listing says that SIM automatically picks the strongest of Telstra, TPG and Optus coverage, and it notes the included SIM is for Reolink cameras only.

The Tapo listings say to insert a SIM card, and neither says one is included, so plan on buying a data SIM yourself. Any prepaid data-only SIM on a network with good coverage at the site should do the job. Before you commit, stand where the camera will go with a phone on the same network and check it has a reliable signal, because a camera with one bar spends its battery trying to upload and still misses clips.

Data use depends almost entirely on how you use it. A camera that sends a short clip for each motion event and gets checked once a day uses very little. A camera you watch live for ten minutes every evening, or one aimed at a busy road so it triggers constantly, can chew through a small plan in a week. Set detection zones tightly, turn on person and vehicle detection so leaves and shadows don't count, and keep live view for when you need it.

Remote sites get one more tip from me. Set up and test the camera at home first, on the same SIM, with the panel connected. Firmware updates over 4G can be large, and it's much easier to get the app paired, the SIM activated and the firmware current while you're sitting at the kitchen table than standing at a farm gate with patchy signal.

Solar panel sizing and the winter problem

The panels in these kits vary a lot, and the listings that state a figure make it easy to compare. The Reolink Go Ultra kit includes a 6W panel, and the Altas Go PT comes with a 12W panel feeding a 20,000mAh battery. The Go PT Plus and both Tapo kits include a panel but don't state its wattage on the listing, so check the current listing or the box if you're putting it somewhere shaded.

Here's the rough maths, with the assumptions stated. A 6W panel in good sun for about three hours a day, which is a fair winter figure for much of NSW, makes around 18Wh on paper, and real-world losses from angle, heat and charging usually cut that by a third or more. A camera that wakes for lots of motion events, runs its infrared lights all night and pans to follow things can use most of that. A 12W panel gives you twice the margin, which matters most in June and July.

Placement matters more than wattage. A panel facing north, tilted up at roughly the latitude angle and clear of shade from 9am to 3pm will beat a bigger panel stuck under an eave. Gum trees are the usual culprit on rural blocks, since a panel that's in full sun in December can sit in shade all winter as the sun drops lower. If you've used portable solar panels for camping, it's the same story at a smaller scale.

Dust, bird droppings and pollen cut output too, so wipe the panel a few times a year. The cable between panel and camera is the other weak spot. Run it with a drip loop so water runs off before reaching the plug, clip it so it can't flap in the wind, and keep it out of reach of cattle, dogs and whipper snippers, because a chewed solar lead is a flat camera within a week.

Batteries in the cold and the heat

These cameras run on lithium-ion packs, and lithium has two weak points outdoors. In cold weather it delivers less capacity and, more importantly, it shouldn't be charged below about 0°C, so a good camera stops charging on a frosty morning until the pack warms up. On the Tablelands or out west that can mean a few slow-charging days in a row. In summer the bigger risk is heat, because a camera in full sun on a dark post can get far hotter than the air.

Heat ages a lithium pack faster than anything else. A battery that spends every summer afternoon above 50°C inside its case will lose noticeable capacity within a couple of years, and that's when people notice the camera going flat overnight in winter. Mount the camera under an eave or a small hood if you can and leave the panel in the sun, which is why a panel on a lead beats one built into the camera body.

Battery life claims are tested under light use. Reolink says the Altas Go PT runs up to 7 months on a full charge in normal use, or 7 days if you switch on 24/7 recording. That second number is the honest one for anyone thinking of continuous recording on battery: the solar panel has to replace a full day's use every day, and in winter it often can't.

Pan and tilt, resolution and night vision

Four of the five picks are pan and tilt cameras. The Go PT Plus pans 355° and tilts 140°, and the Altas Go PT, both Tapo kits and the Go PT Plus all offer some form of 360° coverage with auto tracking, where the camera follows a person or car across the frame. The Go Ultra is a fixed bullet camera, which suits a single gate or driveway and has fewer moving parts to wear out. Pan and tilt motors are the most likely mechanical part to fail in these, so a fixed camera is a fair choice if one view is enough.

Resolution goes from 2K 3MP on the Tapo C615G to 5MP on the Go PT Plus and 4K 8MP on the Go Ultra and the Tapo C665G. The Altas Go PT listing doesn't state a resolution, though it does give the sensor as 1/1.8 inch with an F1.0 lens, which is large for a battery camera and helps more at night than a higher pixel count does. More pixels mean bigger clips, and over 4G that means more data and slower uploads, so 4K isn't automatically better here.

Night vision comes in two kinds. Infrared gives a black and white picture without lighting anything up, and the Go Ultra lists IR night vision. Colour night vision uses a larger lens, a sensitive sensor or a spotlight to keep colour after dark, and the Altas Go PT, both Tapo kits and the Go PT Plus listings all mention colour, starlight or HD night vision of some kind. A spotlight that switches on also uses battery, so expect a busy driveway to drain a colour camera faster in winter.

If you want the area lit as well as watched, pairing a camera with solar security lights does a lot for the night footage without asking the camera's battery to run a light.

Storage, pre-recording and what gets missed

Most of the picks record to a microSD card, and several offer optional cloud storage on top. The Tapo C615G listing doesn't state its storage options. The Go PT Plus listing says it comes with a 32GB microSD card, the Go Ultra takes cards up to 128GB, and the Tapo C665G lists both local and cloud storage. On a 4G camera, local recording matters more than usual, because if the signal drops the camera keeps recording to the card and you don't lose the event, you just see it later.

Battery cameras sleep between events and wake on motion, so they can miss the first second or two of something happening. The Altas Go PT's 10-second pre-recording is the answer to that: it keeps a short buffer running and keeps the moments before the trigger. That costs some battery, which is one reason it carries the biggest battery and panel of the group.

The camera itself is the easiest thing to steal or smash, so think about where the card lives. Mount it high, out of easy reach, and if the site gets visitors, cloud storage is worth paying for during the months nobody's there. A card in a stolen camera is no help to anyone.

Mounting it where the signal and the sun both are

The best spot for the view isn't always the best spot for the signal or the sun, and you need all three. Check the 4G signal with a phone at the mounting height, find a panel spot with clear northern sky in winter, and then work out whether the camera can see what you need from there. The panel can usually sit a few metres away on its lead, which gives you more room to get it right.

Water is the long-term killer. The Go PT Plus is rated IP64 and the Tapo C665G IP65, both of which handle rain from any angle but not being submerged or blasted with a pressure washer. The other listings don't state an IP rating. Mount cameras with the lens pointing slightly down, keep the SIM and card covers fully seated after every swap, and read up on how water gets into electronics if you've never seen what a little moisture does to a board over a year.

Lightning and power surges aren't an issue the way they are for wired cameras, because there's no cable back to the house, but a tall metal post on an open paddock is still the highest point around. Mount it on a timber post or the side of a shed where you can. Use stainless screws, because zinc-plated ones rust and stain within a season on the coast.

If a camera goes quiet, check the obvious things first: the SIM's data balance, the panel's lead and the battery level in the app. If it still won't connect or charge, our Erina workshop can test the battery, the charge circuit and the modem before you decide whether it's worth fixing or replacing.

Side-by-side comparison

What we see fail in the workshop: 4G solar cameras

Outdoor battery cameras come into the shop for the same few reasons, and most of them are about water, heat and the battery rather than the camera itself. Here's what usually goes wrong on a camera that's spent a couple of years on a post, and what you can check yourself before you climb a ladder and take it down.

Decision tree: which one should you actually buy?

• Need one camera to sweep a yard or several gates? → The Reolink Go PT Plus at $360 is the best-ranked 4G pan and tilt camera here, with a 32GB card in the box and IP64.
• Shaded or cold site that has to run all winter? → The Reolink Altas Go PT at $331, with a 20,000mAh battery and a 12W panel, the largest stated in this guide.
• One gate or driveway, and you want 4K detail? → The Reolink Go Ultra at $224: a fixed 4K camera with a 6W panel, a SIM included and no pan and tilt motors to wear.
• Small site and the lowest outlay? → The Tapo C615G Kit at $189, sold by Amazon AU, with your own choice of data SIM.
• Want Wi-Fi near the house and 4G further out? → The Tapo C665G Kit at $369: 4K, dual-band Wi-Fi plus 4G, and IP65.
• Camera going flat, dropping off 4G or not charging? → Check the SIM's data, the solar lead and the battery level in the app first. If it's still playing up, bring it to our Erina workshop and we'll test the battery, charging and modem before you spend anything.

Frequently asked questions

Do 4G security cameras need a SIM card and data plan?

Yes. A 4G camera has no Wi-Fi connection to fall back on, so it needs a SIM with data to send alerts, clips and live view. The Reolink kits in this guide include a Reolink SIM that you activate and top up through the Reolink app. The Tapo kits don't include a SIM, so you'll need a data SIM on a network with good coverage where the camera's going. Check the signal with a phone on that network at the mounting spot before you buy.

How much data does a 4G camera use?

It depends mostly on how many motion events it records and how much live view you watch. A camera that sends short clips for a few events a day and gets checked occasionally uses very little. Watching live every evening, or aiming the camera at a busy road so it triggers constantly, can use a small plan quickly. Higher resolutions make bigger clips, so a 4K camera uses more data per event than a 2K one. Tight detection zones and person or vehicle detection keep it down.

Will a solar security camera work through winter?

Usually, if the panel gets several hours of direct sun a day and the camera isn't triggering constantly. Winter means shorter days, a lower sun and more shade from trees and buildings, so a panel that's fine in summer can struggle in June. A bigger panel and battery help, which is why the Reolink Altas Go PT's 12W panel and 20,000mAh battery suit shaded or cold sites. Face the panel north, tilt it up, and keep it clear of shade between about 9am and 3pm.

Can a 4G solar camera record 24/7?

Some can, but battery cameras aren't built for it. Reolink says the Altas Go PT runs up to 7 days with 24/7 recording against up to 7 months in normal motion-triggered use, which shows how much more power continuous recording takes. The solar panel would need to replace a full day's recording every day. For around-the-clock recording, a wired camera system with mains power and a recorder is the better tool, and 4G cameras are best used on motion detection.

Are Reolink SIM cards locked to Reolink cameras?

The Reolink Altas Go PT listing says the included SIM card is for Reolink cameras only, and it recommends checking compatibility with your provider if you'd rather use a different SIM. The listing also says the included SIM automatically picks the strongest of Telstra, TPG and Optus coverage. If you already have a data SIM you want to use, confirm with Reolink that the camera accepts it before you buy, and test it at home first.

Can a water-damaged outdoor camera be fixed?

Often, if it's caught early. Most water damage on outdoor cameras starts at the SIM or microSD cover, where moisture corrodes the contacts and the camera starts dropping off the network or stops recording. Disconnect the battery, dry the camera indoors, and check the slots for green or white residue. Light corrosion can usually be cleaned. If it's reached the board or the charge circuit, it's a board-level repair, and it's worth getting a quote compared with the cost of a new camera.
