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.

钱花在哪里：分辨率是最便宜的部分
在这个产品系列中，从 3MP 升级到 4K 大约要多花 HK$450。从“仅电池供电”升级到“电池供电加完善的安装系统”，成本也大致相同。相比第一种情况，摄像头更换的原因往往是第二种。
3MP 足以让你在三米外认出门口的人。但它不足以在十米外看清车牌，而且这一价位范围内的电池摄像头无论如何都无法可靠做到这一点——那是有线 PoE 摄像头的工作。4K 带来的是裁剪画面的能力：你可以从广角画面中裁出一张人脸，而不用寄希望于对方走得足够近。
各档位能为你带来什么
- 3MP - Argus 3E 和 B420。适合近距离的日间识别，配备聚光灯后支持彩色夜视，3E 还提供 128GB 存储空间。如果你要监控前门或小型庭院，可以从这里开始。
- 5MP - 3 Pro、B340、Solar、PT。最佳平衡点。3 Pro 配备 105 度镜头和双频 Wi-Fi；PT 增加了可水平和垂直转动的云台，因此一台摄像头就能覆盖更大的区域。
- 4K / 8MP - 3 Ultra、PT Ultra、B360、4 Pro、Altas PT Ultra。提供更远距离的细节和更大的裁剪空间；其中 4 Pro 和 Altas PT Ultra 通过单个安装座即可实现真正宽广的 180 度或 355 度视野。
电池供电、太阳能供电还是插电供电——真正重要的选择
这里的每一款摄像头都使用可充电电池。问题在于，由谁来给它充电。
仅电池供电。 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.
