What should you look for in a good detector?
A reliable comparison of home security devices focuses on objective features. Technical reliability matters more than design or brand name. We evaluate each device using these key criteria.
Certifications and quality marks: Independent quality marks such as VdS certification are essential. They confirm that a detector meets strict standards and can work reliably in an emergency. Look for the VdS mark.
Service life and maintenance: Most modern smoke detectors are designed to last 10 years. Their batteries last for the full service life, reducing the risk of a dead battery and providing long-term protection.
Features and operation: A test button for regular checks is essential. Features such as an LED display on CO detectors or the ability to connect devices can make them more convenient. The alarm should be loud enough to hear.
Tip: Test your detectors every month using the test button. You could schedule the check for the first day of each month. That way, your detectors stay ready to use.
Smoke detector comparison: 2026 models
Long-lasting models dominate the smoke detector market. Here are the most relevant types and selected products from our range.
VdS certification as a mark of quality
For added peace of mind, choose detectors with VdS certification. These devices meet rigorous standards. One excellent example is the
. This 10-year smoke detector with VdS certification uses tested technology designed to last a decade. Install it and enjoy peace of mind for years to come.
VdS testing evaluates early warning performance, resistance to interference from dust or insects, and the long-term durability of the electronics. These detectors are also suitable for landlords who need to meet legal requirements.
Practical multi-packs for several rooms
Most households need more than one detector. A multi-pack of identical devices is a practical and often cost-effective option. The
, a 3-pack of 10-year RM218 smoke detectors, is ideal for an apartment. Use them to protect bedrooms and hallways.
Multi-packs give you identical devices that work the same way and are easy to maintain consistently. They're also easier to install. Before choosing individual devices or a set, consider how many rooms you need to protect.
Warning: Never ignore a beep that signals a low battery or the end of a detector's service life. With a 10-year detector, a beep means the entire device will soon need to be replaced. A detector that doesn't work can't protect you.
Carbon monoxide detectors for added protection
Carbon monoxide (CO) is an odorless, deadly gas produced by incomplete combustion, such as in a faulty gas furnace or fireplace. A dedicated CO detector is essential in any home with these appliances.
One recommended model is the
. The CC-4100 carbon monoxide detector has a clear LED display that shows the current CO concentration in your home's air. You can check for elevated levels even when there's no alarm, helping you spot potential problems early. The digital display gives you a clearer picture of CO levels in your home.
Combine smoke and CO detectors for all-around protection. Place your CO detector near potential sources of danger, but not too close, to help prevent false alarms. Find more information about all our devices in our home security technology overview.
How do you install and maintain smoke and CO detectors correctly?
Even the best technology is ineffective if a detector is installed in the wrong place. Follow a few basic rules when installing smoke detectors.
Best location: Always install smoke detectors on the ceiling. The ideal spot is in the center of the room, at least 50 cm from walls or light fixtures. Kitchens and bathrooms with a lot of steam can trigger false alarms, so check whether a detector is suitable for these areas.
Maintenance routine: Although 10-year detectors need little maintenance, they still require occasional attention. Press the test button monthly. Dust the device occasionally with a dry cloth to keep the sensor openings clear. Make a note of the installation date or the expiration date printed on the device.
Note: When you move, permanently installed detectors can often be removed and taken with you. Look for adhesive mounting plates that won't damage the wallpaper. Before reusing a detector, always check its remaining service life and make sure it works properly.
Buying advice for your home
The safety equipment you need depends largely on your apartment or house. Our buying guide will help you choose the right products.
For renters: First check whether your landlord has already installed detectors. If not, long-lasting 10-year models are ideal because you can take them with you when you move. A set such as is perfect. A CO detector () is essential if you have a gas boiler.
For homeowners: You're planning for the long term. Invest in high-quality, certified detectors such as the . Remember to cover every floor and room. A carbon monoxide detector is essential if you have a fireplace or oil heating system. Keep a record of the installation in case you need it for insurance purposes.

How will safety technology develop in the future?
Safety products are evolving, too. We can already see some clear trends for the coming years.
Interconnectivity and smart home technology: More and more detectors can connect via radio or Wi-Fi. If one device in the basement triggers an alarm, a signal sounds in the bedroom at the same time. Some models send push notifications to your smartphone, even when you're away from home.
Combination devices: Some manufacturers are beginning to offer devices that detect smoke, carbon monoxide and even natural gas. These all-in-one solutions could become more popular in the future, but they're currently more complex to buy. Sensor technology is becoming increasingly precise and less prone to false alarms.
For 2026, however, proven, certified standalone devices currently offer the most reliable protection. Choose quality and well-established technology.

Frequently asked questions
- What does VdS approval mean for a smoke detector?
- VdS approval is an independent certification mark for safety products. Detectors with this approval undergo strict testing for functional safety and reliability. They're considered high-quality products and are often required for commercial use or rental properties.
- How many smoke detectors do I need in my home?
- For a basic level of protection, install a smoke detector in every bedroom, children's room and hallway that serves as an escape route. In larger apartments or houses, an additional detector in the living room is recommended. A 3-piece set often covers the basic requirements.
- Can I replace a 10-year detector before the end of its service life?
- Yes, you can replace the detector at any time. The advantage of 10-year models is their long-life, low-maintenance battery. Replace the device no later than the expiration date printed on it, since sensors age over time. You can also replace it sooner if it's damaged.
- Where should I install a carbon monoxide detector?
- Install a carbon monoxide detector in rooms with fuel-burning appliances such as gas boilers, wood-burning stoves or heating systems. Ideally, place it at breathing height on the wall or ceiling, but not directly above the appliance. Bedrooms next to a boiler room are also important locations.
- What should I do if my smoke detector is beeping?
- A short, regular beep usually indicates a low battery. With 10-year detectors, this signals the end of the service life, so replace the entire device. A loud, continuous alarm warns of smoke. Leave the property immediately and call the fire department.
