Choosing a security camera: avoid costly mistakes and find the right one

Buying a security camera seems simple until you have to choose between a Wi-Fi security camera, a wireless security camera, an indoor model or a camera with a solar panel. Marketing copy often focuses on high resolution, smart detection and long battery life. But these terms don’t tell you everything about day-to-day use.

Look out for these common pitfalls:

  • High resolution without good night vision: 2K or 5MP gives you more detail during the day, but a small sensor or limited infrared lighting can still produce grainy footage at night.
  • Battery life without clear usage conditions: actual battery life depends on motion alerts, recording, temperature, Wi-Fi range and how often you view the live feed.
  • Smart detection that doesn’t automatically prevent all false alerts: check whether person or vehicle detection is available and whether you can set activity zones.
  • Storage costs that only become clear later: local storage via microSD can be an alternative to cloud storage, but check the maximum card capacity and whether a card is included.

Which security camera is right for your situation?

First, decide exactly what you want to monitor. An indoor security camera is suitable for a living room, nursery, office or shop. For a garden, shed, driveway or front door, you’ll need an outdoor security camera with suitable weather resistance.

A wireless model is practical if you don’t want to run a network cable. But make sure you understand the difference between wireless network connectivity and being completely cable-free. A battery-powered camera needs recharging; a solar security camera can reduce the upkeep, but needs enough daylight and careful positioning.

For renters, a compact camera with a magnetic base, adhesive mount or a model placed behind glass can be a good option. If you place a camera behind a window, always check for reflections and glare at night.

Three technical points to check before buying

1. Image quality and night vision

Resolutions such as 1920 × 1080, 2560 × 1440 and 2880 × 1616 give you a useful indication of how much detail an image contains. More pixels don’t automatically mean faces or number plates will always be recognisable. The viewing angle, frame rate, lens and lighting also play a part.

A camera with night vision usually uses infrared LEDs. Check the stated range, but bear in mind the effects of walls, rain, backlighting and mounting height. A night-vision camera for a small hallway has different requirements from a model for a long driveway.

2. Motion detection and alerts

A motion-detection camera can send alerts when it detects movement. On models with person or vehicle detection, you can often set alerts more precisely. Also check whether the camera supports activity zones and privacy zones. These help reduce alerts triggered by a public pavement, moving trees or a busy window.

A PIR sensor measures changes in infrared radiation. This is different from software-based image analysis. According to the product specifications, some models combine both technologies. Actual accuracy depends on the surroundings and settings.

3. Power, weather resistance and storage

For outdoor use, an IP65 or IP66 rating is relevant. IP65 means the casing is protected against dust and water jets; IP66 offers greater protection against powerful water jets. Neither rating means the camera can be submerged.

Also check:

  • maximum microSD capacity;
  • support for local recording or cloud storage;
  • subscription costs for additional cloud features;
  • 2.4GHz or dual-band Wi-Fi;
  • whether two-way audio is available;
  • operating temperature limits;
  • available app and firmware updates.

Don’t place a smart IP camera where it unnecessarily records neighbours, passers-by or a private space. Inform anyone concerned where necessary and use privacy zones. For business use, also check the relevant privacy rules.

Frequently asked questions about security cameras

Does a Wi-Fi security camera work without the internet?

You’ll usually need Wi-Fi for live viewing, alerts and app controls. Some models can record locally to a microSD card if the internet connection temporarily drops. Check which features remain available offline for each model.

How long does the battery in a wireless security camera last?

It varies by camera and usage. Frequent live viewing, night lighting, frequent alerts and low temperatures all shorten battery life. A solar security camera can reduce how often you need to recharge it, but performance depends on its position, the season and cloud cover.

How much does a security camera cost per month?

A camera with local microSD storage can work without a compulsory cloud subscription. A paid subscription may be required for cloud storage, a longer video history or extra features. So don’t just consider the purchase price: factor in storage, accessories, power consumption and any subscription terms.
