Battery cameras
A fixed camera that reacts, or one that turns and sees color after dark?
Same brand, same resolution, both on batteries, two different jobs. The ZS-GX3S is fixed, states three to six months per charge, watches a door and makes noise; its listing mentions no solar panel. The ZY-C2 recharges from a solar panel, pans 355° and keeps color up to 15 m (49 ft).

| Deterrence | Siren and light | Not stated |
| Card limit | Not stated | Up to 128 GB, or cloud |

A tick marks the better answer on that line only. Counting ticks does not decide the page — the two verdicts below do, because these products answer different questions.
No amazon.com listing was found for this one. We hold references for other markets but none for the United States, so it may not be buyable here — which is the first thing to weigh against anything below.
Prefer the ZS-GX3S for a single approach where a reaction is worth more than coverage — and where the published three-to-six-month range tells you what to expect.
Buy the ZY-C2 where one camera has to see a whole yard, and where a description in color is worth more than a shape in monochrome.
Because the solar model tops itself up from its panel, so its runtime depends on the sun where it is mounted. The real limit is winter, when a small panel produces a fraction of its summer output and the internal battery carries the camera.
For a battery camera, mostly in one direction: a weak connection makes the camera retry, and retrying flattens it. The band is less important than the signal strength at the mounting point, which you should check with a phone before drilling.
Your own property. A camera that can be turned from the app onto the street or a neighbor’s yard can cause trouble as soon as it is able to, not only when it does. Mount the ZY-C2 so its travel stops at your boundary, and use privacy masking if the app offers it.
2K 3MP · battery, 3–6 months stated · PIR detection · siren and light · 2.4 GHz
ieGeek publishes an unusually specific runtime — three to six months per charge — alongside 2K capture, PIR detection and a siren with a white light. It works indoors or out, and it is 2.4 GHz only.
Best for: A shed, a side return or a room with no socket, where the camera should be left alone for a season.
2K 3MP · solar · 355° × 120° PTZ · color night vision to 15 m (49 ft) · card to 128 GB · IP65
A fully wireless solar pan-and-tilt camera with a 130° lens, 2K capture and color night vision stated to 15 m (49 ft). ieGeek supplies warning stickers with it, which is a small detail that says something about how it expects to be used.
Best for: A garden or driveway with sun, where the camera should also be seen to be there.
