EZVIZ HB90 Review: Best Dual Solar Security Camera 2026? Tested on My Waterfront Home, Day & Night
Waking up in the middle of the night and somebody's already in your backyard — nobody wants to feel unsafe in their own home. This is my place here on the Gold Coast: the road out the front, a beautiful waterway out the back, and Surfers Paradise just over there. Amazing place to live, but from a security point of view somebody can come at this house two completely different ways — from the street or from the water. One fixed camera was never going to cut it. So I installed the EZVIZ HB90 Dual 3K kit — a dual-lens solar security camera with auto-tracking — on my own house and pushed it properly.
Today we're installing it, then testing it for real: how far away it detects me, whether the second camera actually follows me around the property, the alerts, two-way talking, the siren, the solar charging — and then we come back and do it all again at night. One honest note up front: this is a few days of real-world use on a real house, not a months-long test. I'll tell you exactly what I saw in that time, good and bad.

01Unboxing: What You Get in the HB90 Dual Kit
Out of the box, this is a substantial security camera. You've got dual 3K cameras giving you two different views from the one unit, triple motors controlling those views, built-in spotlights, a speaker and a microphone. Inside there's a big 10,400mAh rechargeable battery. It's IP65 rated for outdoor use and designed to run from -20°C to 50°C.
The solar panel is one of the main reasons I wanted this kit. I don't want to be taking cameras down to charge them all the time, guys — and on the Gold Coast we've always got plenty of sun. The 8W panel comes on a 3-metre cable, so I can put the camera exactly where I need the coverage and position the panel separately where it actually gets good sunlight.
EZVIZ also throws in a 16GB microSD card at no extra cost. That's local storage straight out of the box — no subscription, no monthly fee, which is very, very important to me. It supports microSD cards up to 512GB if you want more, and EZVIZ has optional cloud storage if you'd rather go that way.
02Installation & App Setup
Installation was very straightforward. Mount the bracket onto the house, attach the camera facing out over the backyard so you get full coverage, position the solar panel where it catches the sun, plug it in — and it starts working straight away. Getting the camera in the right spot is the most important part, so take your time there.
Then the app: download the EZVIZ app and connect the camera to your 2.4GHz Wi-Fi. Once it's connected you can check the live view, make sure both views are pointing where you want them, and you're done. Honestly, it's very easy to set up compared to some other cameras I've installed in the past.
03Why Two Cameras? Water at the Back, Road at the Front
This is where the dual-camera system really makes sense. With a waterway behind the property and a street out the front, I need coverage in more than one area. The upper 3K camera gives you the wider view, and underneath it the second 3K camera gives you the closer view. The upper section can pan remotely, while the lower camera moves and tracks a person around the property using human detection.
Rather than one fixed camera and hoping somebody stays inside the frame, you've got the big picture and a lens that locks onto whoever's moving through it.
04The Gate Test: How Far Out Does It Detect Me?
First proper test: I started away from the camera, down at the gate, and walked towards the house to see when it actually picks me up. I armed it, walked through — and it picked me up straight away. Literally, I'd just stepped through and it went straight into alarm. Great field of vision. "Hello, it's me" — switched the alarm off, and it had well and truly got me.
05Auto-Tracking: Does the Second Camera Really Follow You?
Then I walked across the property to see what the second lens does. It works exactly the way it should: the wide view shows where I'm going, while the lower camera locks on and follows me. All the way down the yard, human detection keeps it locked on me. I'll admit I had a bit of fun with it — the dancing is in the video — but it kept up the whole time.
06AOV 2.0: Always-On Video
The HB90 uses AOV 2.0 — Always On Video. Battery cameras have to manage power carefully, and a lot of them just give you short clip after short clip, so you miss what happened before and after. AOV keeps a continuous record of what's going on, and when it detects something important — a person or a vehicle — it switches to normal-speed recording. You can also just hit record manually whenever you want. For me it means more information about what's actually been happening around the house, not just fragments.
07Detection Zones: Ignoring the Kayakers
Living on the water, there's something you have to get right: I want detection on the yard, but I don't want an alert every time someone canoes or kayaks past. In the app, go into the camera's settings → Intelligent Detection, and you can draw the exact area you want on screen. I drew the yard in — and left the water and the house out. Save it, and that's the zone. You can do it separately for the wide lens and the tracking lens, so both are covered without either one staring at the water.
From there you can set notifications, sound reminders with adjustable volume (we had the sound alarm on earlier — we don't want to scare the neighbours), and human shape detection. I switched vehicle detection off for the backyard since there are no cars back there. There's also local familiar face recognition. And importantly: the AI human and vehicle alerts don't need a subscription. Very, very important.
08Two-Way Talk
Next, two-way talking. I was inside on the app talking to my mum out in the yard — she could see and hear me through the camera. Great microphone, great speaker. You talk straight through the camera from your phone, whether you're greeting a visitor or telling someone they've been spotted.
09Active Defence: Siren & Flashing Lights
This is the deterrent side of it. There's a siren and flashing lights, so rather than just recording somebody who's come onto the property, you make it very obvious they've been detected. I ran a few scenarios walking from inside the house out into the yard — it picked me up, the light went off and the alarm went off. Great sensor on it.
10The Night Test
Testing during the day is one thing — it needs to work at night. So we came back after dark and did the same thing again. Out we come from the house and there it is: detected, light on, siren on, and the camera tracking every move, with notifications coming through on the phone.
You get infrared black-and-white night vision, and when the built-in spotlights come on you get full-colour night vision. With the spotlight on, the footage was very clear, with good coverage across the yard. There's also balanced image exposure, designed to keep detail when you've got a very bright and a very dark area in the same frame.
11The App & Solar After Days of Bad Weather
There are a ton of settings in the EZVIZ app — storage, shortcuts, layout, device tools — and it keeps getting new features through updates. Per camera, you can see the battery level and how the solar's going, choose the power mode (AOV always-on, power saving, or plugged in), and set linkage, audio, image, battery and light settings. You can store to the SD card or use the EZVIZ cloud. Live view, event history and recording are all right there, and the amount you can customise is incredible.
The real result: the solar panel has been running the battery for the last few days and the battery hasn't dropped — and we had some bad weather in that time too. That's a few days, not a winter, but it's exactly what I wanted to see.

The Verdict & Who It's For
The feature I like most is the dual-camera system. A wide 3K view plus a second 3K camera that tracks somebody around the property gives me far better coverage than relying on one fixed view — and on a house you can approach from the water or the street, that's the whole point. AOV gives me more information about what's actually been happening, footage quality is great day and night, the speaker and mic are great, the 10,400mAh battery and 8W solar panel kept it topped up through bad weather, and the included 16GB card means local recording without buying anything else. Setup and the app are genuinely easy. I've run eufy cameras before, and this gives me much greater coverage of the yard.
The catches, honestly: the camera can be removed from its mounting bracket without a tool — so mount it high and out of easy reach, because anyone who can get to it can take it. It connects over 2.4GHz Wi-Fi, so check that signal reaches where you're mounting it. And this is a few days of testing, not a long-term review — the solar result through bad weather is promising, but I'd want to see it through a full winter before calling it set-and-forget.
Who's it for? Anyone with a backyard, a driveway or a waterfront that one fixed camera can't cover — people who want a solar security camera with auto-tracking, colour night vision and AI alerts without paying a monthly fee. If you just need to watch a front door, a single-lens doorbell or camera will do. But if somebody can come at your place from more than one direction, this fits.

?Frequently Asked Questions
Does the EZVIZ HB90 need a subscription?+
No. The AI human and vehicle alerts work without a subscription, and the kit includes a 16GB microSD card for local recording, so there's no monthly fee out of the box. It supports cards up to 512GB, and EZVIZ cloud storage is optional if you want it.
Does the EZVIZ HB90 track people automatically?+
Yes. The upper 3K lens holds the wide view (and pans remotely), while the lower 3K lens uses human detection to lock on and follow a person around the property. In my testing it followed me all the way across the backyard.
How long does the EZVIZ HB90 battery last with the solar panel?+
It has a 10,400mAh battery and comes with an 8W solar panel on a 3-metre cable. Over several days of testing — including bad weather — the solar kept the battery from dropping. That's a short test, not a full winter, so place the panel where it gets good direct sun.
Does the EZVIZ HB90 have colour night vision?+
Yes. It has infrared for black-and-white night vision, and built-in spotlights for full-colour night footage. It also has balanced image exposure to keep detail when bright and dark areas are in the same frame.
Can I stop the EZVIZ HB90 detecting people outside my property?+
Yes. In the EZVIZ app under Intelligent Detection you draw your own detection zones on screen, separately for each lens. I drew mine to cover the yard and exclude the waterway, so kayakers going past don't trigger alerts. You can also switch vehicle detection on or off.
What Wi-Fi does the EZVIZ HB90 need?+
Setup connects it to 2.4GHz Wi-Fi through the EZVIZ app. Make sure your 2.4GHz signal reaches where you plan to mount the camera before you drill any holes.
Where can I buy the EZVIZ HB90 in Australia and New Zealand?+
In Australia it's available from the EZVIZ official store, Harvey Norman and JB Hi-Fi. In New Zealand, Noel Leeming and Harvey Norman NZ. All the links are in the Where to Buy section above.
