While the TechRadar Australia team has been knee-deep in covering this week's Amazon Prime Day sale, we were rocked by the news of my colleague, Max Langridge, recording a break-in attempt at his home with a Ring security camera. It was enough for him to bolster security further by picking up some extra Blink cameras while they're discounted.One of the best things about modern home-security cams is that they're very cheap to purchase, with Ring cameras starting as low as AU$35 for the indoor camera (although the brand has some premium options, too) and Blink with even more affordable offerings from AU$31 for a 2-pack of the Mini 2K+.But there’s a catch with these Amazon-made security cameras — you have to sign up for a monthly subscription to access some of their most useful features, like cloud video storage and movement detection . There are some workarounds with Blink cameras, such as the flash storage-supporting Sync Module 2, but on the whole, you need to pay extra to use the cameras to their full potential.Fortunately, there are plenty of other compelling Prime Day deals on security cameras that don’t require a monthly subscription to access essential features.I’ve pulled together five such subscription-free security camera discounts below, including offerings from reputable brands like TP-Link, Reolink, Wyze and more:The Wyze Cam v3 is an affordable security camera with a microSD slot for video storage and playback, and it can be placed either indoors or outdoors. It ‘only’ supports 1080p resolution (some newer models support 2K or even 4K recording), but it still has good colour and infrared night vision for the price. It is wired, which may be limiting for those who can’t go down this install route, and person detection is, admittedly, still locked behind a subscription. However, our reviewer found the camera is perfectly usable without it, meaning the Cam v3 earns a spot on this list.View DealMoving up to 2K resolution, Imou’s Ranger 2C also has a microSD slot for video storage and playback, and still provides both motion detection and alerts without the need for the Imou Protect subscription service. It also has two-way audio to allow you to communicate with the person (or pet) on the other side, as well as alerting you to unusual sounds, like a baby crying or a barking dog. We’ve reviewed an older version of the Ranger 2C here for more information.View DealFor an extra deterrent, this camera comes with some big, bright spotlights on either side of the unit to illuminate any potential intruders once they trip the motion detection sensor. There’s also a fixed solar panel for additional power so you won’t have to take it down to recharge every few months. It also comes with microSD storage and, while there is a subscription service available, it mainly relates to cloud storage options — something that's not essential due to that microSD slot. Read our Reolink Solar Floodlight Cam review.View DealI’m in the process of testing and reviewing this security camera and so far it’s proving to be a great value option if you want 4K video and local storage via microSD card. This kit comes with a solar panel to keep it powered, and in my experience so far it works a charm — I’ve never had to charge it myself. Plus, the built-in spotlight helps retain colour while capturing footage at night. My only real complaint is with the limited smart home compatibility, although Alexa is fully supported.View DealOur review praised the crisp 4K video recordings, pan-and-tilt functionality to cover an extra-wide area, and local 64GB storage. The Altas PT Ultra works well enough during the day, but its night-time performance is where it excels, thanks to the Reolink ColorX technology capturing impressive colour footage without needing a spotlight. The battery is a large 20,000mAh unit, and the included solar panel also means you generally shouldn't need to manually recharge it.View Deal
