Reolink Battery Cameras in Singapore, the UK and Australia: Which Model, and What It Costs
Why battery cameras, and when not to use them
Battery cameras exist to solve one problem: you cannot, or do not want to, run a cable. Rented flats, older buildings, shophouses, village houses, warehouses, construction sites, temporary sites — anywhere drilling and conduit are off the table. Setup takes ten minutes: mount it, pair it, and add a microSD card.
The trade-off is straightforward. A battery camera records when triggered, not continuously, and it needs to be recharged. If you have mains power at the mounting point and want 24/7 footage, the PoE range (P330, CX410, Duo 3) does the job better and at a lower cost per camera. Battery is for when the cable is the problem.
The range, with all four currencies
Hong Kong dollar prices below are read live from our catalogue when the page loads — they are not entered manually. The SGD, GBP and AUD columns are conversions at the ECB reference rate of 28 October 2026 (SGD 0.16343, GBP 0.095931, AUD 0.18125) and are for reference only: your card issuer sets the final exchange rate.
Not included: 4G models (Go, Altas Go PT, TrackMix LTE) and the PoE range. Stock moves — check the product page before ordering.
The one decision that matters most: fixed or pan-and-tilt
A fixed camera sees one direction. Mounted at a door, it covers the doorway and a bit of the path. A pan-and-tilt camera turns on command, so one unit can sweep a 20-foot shopfront.
But pan-and-tilt does not let you watch two places at once. If you genuinely need both ends of a counter in frame simultaneously, the answer is the dual-lens Argus 4 Pro with its 180° stitched view, not a PT unit.
The price step is clear: Argus 3E at HK$399 to Argus B420 at HK$720 buys you movement for about HK$320. In this range that is the single most useful upgrade per dollar.
Resolution: what 3MP actually looks like
3MP is roughly 2304×1296, 5MP about 2560×1920, 8MP about 3840×2160. The practical measure is the distance at which a face is still identifiable:
- 3MP — 3–5 m for facial features, beyond 10 m you know someone was there
- 5MP — 5–8 m, number plates start to be legible
- 8MP — around 10 m, suitable for car parks, warehouses and gates onto a road
If the question you are answering is "was anyone there, and when", 3MP is enough. If it is "who was it, and can I hand this to the police or my insurer", buy the 8MP and do not compromise in between.
Power: the part overseas buyers underestimate
The Argus 3E is battery-only. Real-world endurance depends on trigger frequency and weather. A residential doorway with a dozen triggers a day runs two to three months. A shopfront with constant foot traffic can need a charge every two to three weeks — and if the camera sits three metres up, that is a ladder every time.
Two honest fixes: add a solar panel (the Argus Solar includes one; others take the Solar Panel 3), or move to a model built for continuous recording (Altas / Altas PT Ultra, 20,000 mAh). Solar only helps where there is direct sun — a covered corridor or a light well in a Hong Kong tenement will not charge anything.
Wi-Fi, realistically
Battery cameras are usually mounted outdoors, and Wi-Fi has to cross one or two walls. Before drilling, stand at the mounting point and check signal on your phone. Two bars or fewer and the live view will stutter. Where there is no usable Wi-Fi at all — construction sites, container yards, outlying villages — the 4G models are the only answer.
Dual-band matters more than the spec sheet suggests: 5GHz gives a smoother live view at short range, 2.4GHz reaches further through walls. The 3E is 2.4GHz only; the 3 Pro, PT Ultra, 4 Pro and Altas PT Ultra are dual-band.
The plug, for each market
These are battery cameras, so most of the time you charge them from USB and the mains plug is only relevant to the charger you use. Two practical notes:
- Singapore and the UK — Type G, the same three-pin plug as Hong Kong. A Hong Kong charger works as-is.
- Australia — Type I, two angled pins. A Type G charger will not enter an Australian socket; use a local USB charger or a plug adapter, roughly A$5–15.
Reolink chargers are USB-A to USB-C, and multi-voltage, so no transformer is needed anywhere.
Warranty when you buy from Hong Kong
Everything on this page is Hong Kong stock, serviced by the Hong Kong distributor. If a unit fails in warranty it travels back to Hong Kong and back to you, and international freight both ways is on the buyer — typically HK$150–350 depending on destination and weight. Turnaround is about 2–4 weeks plus transit. Your local consumer rights in Singapore, the UK and Australia are unaffected. Full detail: cross-border warranty note.

Questions before ordering
Do these need a monthly subscription?
No. A microSD card gives local recording with no recurring cost. Cloud is optional, and only worth it if you want footage to survive the camera being removed.
How long does the battery last?
Trigger-dependent. A dozen events a day runs two to three months; constant foot traffic can be two to three weeks. Solar extends this where there is sun.
Is 3MP enough to identify a face?
At 3–5 m, yes. Beyond 10 m you can tell someone was there but not who. For identification at distance choose 5MP or 8MP.
Will they work in heavy rain?
The range is built for outdoor use with weatherproof housings. Official IP ratings vary by model — where the manufacturer does not publish one, we do not invent it. Check the product page for the specific model.
How long is shipping?
From Hong Kong: Singapore typically 5–9 business days, the UK 6–10, Australia 7–12. Tracking is issued when the parcel leaves our warehouse.
