Q: What resolution do I need to capture a number plate on my driveway?

You need at least 2K (4MP) resolution , ideally with a narrow field of view (50–70°) pointed directly at the entry point. At 1080p, number plates are often readable in good light but become blurry at distance or in low light. A 4K camera with optical zoom gives you the best chance of capturing a clear plate at night. Position matters as much as resolution — a 4K camera mounted too high or at a wide angle will still produce unusable footage.

Q: Can I use cameras from different brands together on one system?

Yes, if the cameras support the ONVIF standard — most professional and prosumer cameras do. ONVIF compliance means a Hanwha camera can feed into a Hikvision NVR, or a LevelOne camera can be managed alongside Axis hardware. Consumer brands like Ring, Arlo, and TP-Link Tapo use proprietary ecosystems and generally don't support ONVIF, so mixing brands within those ecosystems isn't possible. If you're building a mixed system, check for ONVIF Profile S or Profile T support, and also look for RTSP stream support, which allows integration with third-party software like Blue Iris or Home Assistant.

Question 1

What resolution do I need to capture a number plate on my driveway?

Accepted Answer

You need at least 2K (4MP) resolution, ideally with a narrow field of view (50–70°) pointed directly at the entry point. At 1080p, number plates are often readable in good light but become blurry at distance or in low light. A 4K camera with optical zoom gives you the best chance of capturing a clear plate at night. Position matters as much as resolution — a 4K camera mounted too high or at a wide angle will still produce unusable footage.

Question 2

Is a Wi-Fi security camera reliable enough for permanent outdoor use?

Accepted Answer

Wi-Fi cameras are convenient but not as reliable as PoE for permanent installations. Signal strength degrades through walls and at distance, and any router reboot or broadband outage takes the camera offline. For a front door or porch close to your router, a 5GHz Wi-Fi camera is generally fine. For a garage, outbuilding, or far corner of a garden, a PoE camera on a Cat6 cable will give you far fewer headaches. If running cable isn't an option, a 4G/LTE camera is a better fallback than stretching a weak Wi-Fi signal.

Question 3

Do I need to pay a monthly subscription for cloud storage?

Accepted Answer

Not necessarily — several cameras offer free local storage via microSD card with no ongoing fees. TP-Link Tapo, EZVIZ, and Reolink all support microSD recording without a subscription. Ring and Arlo, by contrast, limit free users to live view only, with recorded history locked behind a paid plan. Before buying, check the free tier carefully: some brands offer 24 hours of event clips for free, others offer nothing. If you want to avoid subscriptions entirely, pair a PoE camera with a local NVR — it's a higher upfront cost but zero ongoing fees.

Question 4

What does IP65 actually mean, and is it enough for a UK outdoor camera?

Accepted Answer

IP65 means the camera is fully dust-tight and protected against low-pressure water jets from any direction — more than sufficient for rain, even in a British winter. The first digit (6) covers dust ingress; the second (5) covers water. IP66 adds protection against powerful water jets, and IP67 means it can be submerged briefly. For a standard outdoor wall mount under an eave, IP65 is adequate. For a fully exposed location or near a hosepipe, IP66 is worth seeking out. Avoid any outdoor camera that doesn't state its IP rating explicitly.

Question 5

Can I use cameras from different brands together on one system?

Accepted Answer

Yes, if the cameras support the ONVIF standard — most professional and prosumer cameras do. ONVIF compliance means a Hanwha camera can feed into a Hikvision NVR, or a LevelOne camera can be managed alongside Axis hardware. Consumer brands like Ring, Arlo, and TP-Link Tapo use proprietary ecosystems and generally don't support ONVIF, so mixing brands within those ecosystems isn't possible. If you're building a mixed system, check for ONVIF Profile S or Profile T support, and also look for RTSP stream support, which allows integration with third-party software like Blue Iris or Home Assistant.

Question 6

Are cheap security cameras worth buying, or are they a false economy?

Accepted Answer

Budget cameras under 40 £ are worth buying for low-stakes indoor monitoring, but they're a false economy for serious outdoor security. The main compromises at the very low end are poor night vision, unreliable motion detection that generates constant false alerts, weak app support, and — critically — questionable data security. Some ultra-cheap cameras have been found to transmit footage to overseas servers with minimal encryption. Stick to known brands even at the budget end: TP-Link Tapo and EZVIZ offer genuinely good value without those risks. For outdoor use, spending a little more to reach the 40 £–82 £ bracket makes a meaningful difference in reliability and image quality.

Question 7

What's the difference between a bullet camera and a dome camera?

Accepted Answer

Bullet cameras are cylindrical and directional; dome cameras are hemispherical and more discreet. Bullets are easier to aim and typically have longer IR range, making them well-suited to driveways and long corridors. Domes are harder to tamper with (the lens direction isn't obvious), blend into ceilings more naturally, and are often vandal-resistant. Turret cameras are a hybrid — dome-shaped housing but with a ball-and-socket mount that makes repositioning easy. For most home outdoor use, a bullet or turret camera is the practical choice; domes are more common in retail and commercial settings where aesthetics and tamper-resistance matter.
