What to look for in a solar security camera
Solar panel wattage matters more than you think. A 2.5W panel will struggle in a UK winter. Look for 4W or above if you want year-round charging without manual top-ups. The eufyCam S4’s 5.5W SolarPlus 2.0 is the benchmark in this roundup.
Battery backup is your safety net. Solar cameras with a larger built-in battery handle cloudy weeks better. 10,000mAh is the sweet spot for UK conditions — the Tapo models hit this.
AI detection without a subscription. Every camera on this list includes person, vehicle and pet detection with no monthly fee. This is now standard for solar cameras — avoid any model that paywalls basic AI detection.
IP rating for UK weather. IP65 is the minimum for outdoor use. IP66 handles heavier rain. IP67 is the highest available on a solar camera in this roundup and that is only the eufyCam 3.
The best solar security cameras UK 2026
#1 Best Overall
£299
eufyCam S4
Resolution: 4K bullet + dual 2K PTZ |
Solar: 5.5W SolarPlus 2.0 — 1hr sun = all day |
IP: IP65 |
Wi-Fi: 2.4GHz
Pros
- + 4K bullet + 2K PTZ in one unit
- + Alexa + Google
- + 5.5W solar — most efficient in this roundup
- + 32GB built-in storage, no subscription needed
- + 105dB siren + radar and PIR detection
Cons
- − 2.4GHz only
- − HomeBase S380 sold separately for full features
- − Higher price than single-lens alternatives
Our verdict
The eufyCam S4 is the most capable solar security camera available in the UK right now. The combination of a fixed 4K bullet camera and a 2K PTZ that auto-tracks motion in a single unit is genuinely unique at this price. Alexa and Google support is included. The 5.5W SolarPlus 2.0 panel is the most efficient in this roundup — just one hour of direct sunlight keeps it running all day. The 105dB siren and radar + PIR dual detection round out a package that is hard to beat.
Best for: Anyone who wants the best single outdoor solar camera available, especially those who want 32GB built-in storage and no subscription.
Watch out for: 2.4GHz only — no 5GHz. HomeBase S380 sold separately for 24/7 recording.
#2 Best 4K Solar
£237.99
Tapo C675D
Resolution: Dual 4K (3840×2160 per lens) |
Solar: 4.5W — 90 min sun = all day |
IP: IP65 |
Wi-Fi: Dual-band 2.4GHz + 5GHz
Pros
- + Dual 4K on both lenses
- + 18× hybrid zoom
- + Dual-band Wi-Fi
- + 3 months battery without solar
- + Samsung SmartThings support
Cons
- − IP65 only
- − 15fps
- − Higher price than 2K alternatives
Our verdict
The Tapo C675D is the best dual 4K solar camera in the UK market. Both lenses shoot at full 4K resolution — that is not a compromise you see on many dual-lens cameras where the telephoto is often lower resolution. The 169° wide-angle and 360° pan/tilt telephoto combination with 18× hybrid zoom gives exceptional coverage. Dual-band Wi-Fi is a meaningful advantage over single-band competitors. Samsung SmartThings support is a useful bonus.
Best for: Large properties needing 4K dual-lens coverage with solar power and no subscription.
Watch out for: IP65 not IP66. 15fps frame rate.
#3 Best Value Solar
£109.99
Tapo C645D
Resolution: Dual 2K 3MP (2304×1296 per lens) |
Solar: Solar + 10,000mAh battery |
IP: IP65 |
Wi-Fi: Dual-band 2.4GHz + 5GHz
Pros
- + Dual 2K lenses
- + Dual-band Wi-Fi
- + Solar + 10,000mAh battery
- + No-subscription AI detection
- + Excellent value at £109.99
Cons
- − 2K not 4K
- − IP65
- − 15fps
Our verdict
The Tapo C645D is the best value dual-lens solar camera in this roundup. At £109.99 you get dual 2K lenses, solar charging, dual-band Wi-Fi and no-subscription AI detection — a combination that costs significantly more from Ring or Arlo. The auto-tracking telephoto lens handles motion well and the 165° wide-angle covers a large area. The step up to the C675D is only justified if you specifically need 4K.
Best for: Anyone who wants dual-lens solar coverage without paying flagship prices.
Watch out for: IP65 not IP66. 15fps.
#4 Best Budget Solar PTZ
From £111 (with solar panel)
Reolink Argus PT Ultra
Resolution: 4K 8MP |
Solar: 6W solar panel (included in bundle) |
IP: IP65 |
Wi-Fi: Dual-band 2.4GHz + 5GHz
Pros
- + 4K at budget price
- + 355° pan / 140° tilt
- + Dual-band Wi-Fi
- + No-subscription AI
- + 6W solar panel in bundle
Cons
- − Single lens only
- − No Apple HomeKit
- − Solar panel sometimes sold separately
Our verdict
The Reolink Argus PT Ultra delivers 4K pan/tilt solar at a price point that undercuts almost everything else in this list. It does not have the dual-lens design of the Tapo models or the PTZ-plus-bullet combination of the eufyCam S4, but as a single-lens solar PTZ camera with 4K and 355° pan coverage it is hard to beat at the price. No-subscription AI detection and dual-band Wi-Fi are standard.
Best for: Budget-conscious buyers who want 4K solar pan/tilt coverage without paying flagship prices.
Watch out for: Single lens only. Check the bundle includes the solar panel — camera-only listings are cheaper but do not include it.
#5 Best Weatherproofing
From £189.99 (2-cam kit)
eufyCam 3
Resolution: 4K 8MP |
Solar: Integrated Forever Power solar panel |
IP: IP67 |
Wi-Fi: 2.4GHz
Pros
- + IP67 — highest weatherproofing in this roundup
- + Alexa and Google support
- + Integrated Forever Power solar panel
- + 4K resolution
- + No subscription for AI detection
Cons
- − HomeBase 3 required for storage
- − 2.4GHz only
- − No Apple HomeKit
- − Higher total cost with HomeBase
Our verdict
The eufyCam 3 is the only camera in this roundup with an IP67 rating — a step above the IP65 of every other model here. IP67 means it can withstand temporary water immersion, making it the most robust choice for very exposed locations. The integrated Forever Power solar panel is designed to keep the battery topped up indefinitely in normal UK conditions. Note that HomeBase 3 is required for local storage, which adds to the total cost.
Best for: Exposed outdoor locations where maximum weatherproofing matters most.
Watch out for: HomeBase 3 required for local storage — additional cost. 2.4GHz only. Note: Apple HomeKit is not supported on the eufyCam 3.
