The Argus 3E is HK$399 and it is genuinely the right camera for a lot of people. But thirteen battery models sit around it, from HK$399 to HK$1,599, and the differences that matter are not the megapixels - they are what powers the camera, how much it can store, and whether it survives your weather. This is the whole lineup, priced for Singapore, the UK and Australia.
The range, with all four currencies
Hong Kong prices are read from our product pages. Singapore, UK and Australian figures are converted at today's rate and rounded - they are a guide to relative cost, not a quote; your local duties and shipping are separate.
Where the money goes: resolution is the cheap part
Going from 3MP to 4K costs you roughly HK$450 in this lineup. Going from "battery only" to "battery plus a proper mounting system" costs about the same. Cameras get replaced for the second reason far more often than the first.
3MP is enough to recognise a person at your gate at three metres. It is not enough to read a number plate at ten metres, and no battery camera in this range will do that reliably anyway - that is a job for a wired PoE camera. What 4K buys you is the ability to crop: you can pull a face out of a wide shot instead of hoping they walked close enough.
What each tier gives you
- 3MP - Argus 3E and B420. Daytime identification at short range, colour night vision with the spotlight, 128GB storage on the 3E. If you are covering a front door or a small yard, start here.
- 5MP - 3 Pro, B340, Solar, PT. The sweet spot. The 3 Pro adds a 105-degree lens and dual-band Wi-Fi; the PT adds a pan-and-tilt head so one camera covers a wide area.
- 4K / 8MP - 3 Ultra, PT Ultra, B360, 4 Pro, Altas PT Ultra. Detail at distance, better crop latitude, and on the 4 Pro and Altas PT Ultra a genuinely wide 180-degree or 355-degree view from a single mount.
Battery, solar, or plug-in - the decision that actually matters
Every camera here runs on a rechargeable battery. The question is who recharges it.
Battery only. You climb a ladder every few weeks to months, depending on how busy the scene is. A quiet driveway can go months; a footpath with passing cars will drain a battery in weeks because the camera wakes constantly. If the camera is above a first-floor window, buy solar or accept the ladder.
Solar. The Argus Solar has the panel built into the camera body. In Singapore this is close to a no-brainer - a few hours of decent sun refills the battery, and the panel angle matters more than the daily total. In the UK and Australia the honest answer is seasonal: a south-facing panel in Sydney keeps up most of the year, a north-facing wall in Manchester will not keep up in December and you will be topping the battery up manually. Do not buy solar for a shaded position and expect it to work.
Wired where possible. Several models accept continuous DC power, which turns them into always-recording cameras rather than motion-triggered ones. If you have a socket near the mounting point, that is the most reliable configuration in every one of these three countries.
Storage: 128GB or 512GB
The 3E takes up to 128GB. The 3 Pro, 3 Ultra, PT Ultra, 4 Pro and Altas PT Ultra take 512GB. At 4K, 128GB fills quickly - a week or two of event clips, not months. If you want to keep footage after an incident without downloading it immediately, the 512GB models are the ones to pick. None of these need a hub; the card sits in the camera.
Weatherproofing, stated plainly
Reolink publishes an IP rating for some models and not others. Where it is published: IP67 on the MagiCam and the Solar, IP66 on the Argus 4 Pro. The Altas PT Ultra is the one to watch - the product page says IP65 in the feature list and IP66 in the FAQ. We have left both numbers visible rather than pick one; if IP rating is a deciding factor for you, confirm with the seller before ordering.
For Singapore, IP65 or better is sensible for anything under a balcony edge but exposed to driving rain. For the UK, water is the issue and wind-driven rain finds gaps - mount under an eave. For Australia, sun is the bigger enemy than rain: UV degrades plastic housings and the battery hates sustained heat, so shade the body even if the panel is in sun.
Which one for which job
Plugs, voltage, and what arrives in the box
These are battery cameras. Charging is by USB, so mains voltage is irrelevant - a UK 230V socket and a Singapore 230V socket both feed the same USB charger, and Australia's 230V supply works through a Type I adapter, which costs a couple of pounds.
Singapore and the UK use the same Type G plug, so a unit bought from us works out of the box in both. Australia needs a Type I adapter for the charger only - it is not a transformer, just a shape, and any travel adapter will do. Nothing here needs a voltage converter, and using one would be a bad idea anyway.
Delivery and warranty, for overseas buyers
Hong Kong: 1-2 working days. Singapore: 5-9 working days. UK: 6-10 working days. Australia: 7-12 working days.
Warranty is a Hong Kong warranty. If a unit fails inside the warranty period we repair or replace it in Hong Kong, but you ship it to us and we ship it back - return freight is yours, typically HK$150-350 in each direction depending on destination, and the round trip takes 2-4 weeks. That is the honest cost of buying a Hong Kong unit from overseas, and it is worth weighing against a local purchase with local warranty if the unit is mission-critical.
Questions we get asked
Can I use the Argus 3E without any subscription?
Yes. Recording to microSD, live view, motion alerts and two-way audio all work with no cloud plan. A subscription only adds cloud backup.
Will the battery really last months?
Only in a quiet scene. Battery figures assume a handful of triggers a day. A camera pointed at a road will need charging far more often, and no manufacturer figure survives a busy footpath.
Does it work with Alexa and Google?
The current models in this range do, for live view on a smart display. Use it as a convenience, not a monitoring system.
What is the difference between the 3E and the 3 Pro?
Resolution (3MP vs 5MP), a wider 105-degree lens, dual-band Wi-Fi and 512GB storage instead of 128GB. If the camera is more than three metres from what you want to identify, pay the extra.
Can I take it with me if I move country?
Yes. Battery cameras are not region-locked and the charger is USB. The only thing that changes is the plug adapter.
Do I need a hub or base station?
No. Every camera in this table records to its own microSD card.
The short version
Buy the 3E if the camera is close to what you want to see and you can reach it to recharge. Buy the 4 Pro or Altas PT Ultra if you need one camera to see a whole area at once. Buy solar only if the panel gets real sun. And if the camera is somewhere you cannot comfortably reach, solve the power problem before you solve the resolution problem - a 4K camera with a flat battery records nothing.
