Professional installation of surveillance cameras: What you should pay attention to

The security of your own home is a key concern for many homeowners. Anyone who wants reliable and legally compliant video surveillance is faced with a decision: install it themselves or hire a specialist company? In this blog post, we'll show you when professional installation makes sense, what you should consider, and common questions – including legal information, technical tips, and planning assistance.

Why a professional camera installation?

A surveillance camera is only as good as its placement, power supply, and network connection. Hiring a company to install it benefits from:

• Professional planning and positioning

• Clean, weather-protected cabling

• Legal certainty regarding data protection and GDPR

• Technical advice on camera types & functions

Especially when it comes to wired solutions (e.g. PoE cameras) or complex outdoor installations, a specialist company is usually the only option.

1. How many cameras do you need – and where?

One of the most frequently asked questions is, “How many cameras do I need?” The answer depends on the size of your property and the areas you want to monitor.

Rules of thumb for planning:

• Cover house entrance, courtyard entrance, garden and side entrances separately

• Avoid blind spots: prefer more cameras with overlapping view

• Indoors: Secure corridors, cellar doors and passageways

Mounting height:

• Outdoor area: at least 2.5 to 3 meters to prevent vandalism

• Indoor area: approx. 2.3 to 2.5 meters

A professional will help you with optimal positioning and also plan for difficult corners.

2. Power supply and network: battery or cable?

A key issue during installation is the power supply. We distinguish between two main types:

Wired cameras (PoE / power supply):

• Stable connection (ideal for continuous operation)

• No charging breaks

• Requires professional installation

Battery-powered cameras:

• Flexible in assembly

• Ideal for rental properties or without electricity connection

• Limited runtime and dependent on Wi-Fi strength

A specialist company can plan both – even in combination (hybrid solutions).

3. Weather resistance and outdoor installation

For outdoor cameras, weather conditions play a major role. Important:

• Protection class at least IP65 or IP66 (dust & splash water)

• Robust housing against wind, rain and frost

• Installation in slightly shielded areas (e.g. under eaves)

A professional knows the typical sources of error, such as direct sunlight, spider webs in front of the lens, or glare from outside light.

4. Storage: SD card or cloud?

Many cameras today offer flexible storage options. The most common question is: "Where are the recordings saved?"

Local storage (SD card / recorder):

• Full data sovereignty

• No internet access required (offline recording)

• Limited storage, automatic overwriting required

Cloud storage:

• Automatic backup & updates
  

• Note subscription costs & data protection

An installer can help you set it up and explain the advantages and disadvantages of each model.

5. Legal basis & data protection (GDPR)

There are clear rules for private video surveillance in Germany:

• Only your own property may be filmed (no public roads, no neighboring properties)

• A sign must be clearly visible

• Recordings may not be stored indefinitely (max. 72 hours recommended)

A professional company knows the legal framework and ensures that your system is implemented in compliance with data protection regulations.

6. Product selection & range of functions

Another advantage of expert advice: You receive the right technology for your requirements.

Typical additional functions:

• Motion detection with AI (differentiation of people, animals, vehicles)

• Night vision in color or infrared

• Two-way audio (e.g. with doorbell cameras)

• Integration into smart home systems (e.g. Alexa, Google Home)

A specialist company can also offer hybrid solutions, such as wireless cameras indoors and wired versions outdoors.

7. Frequently Asked Questions (FAQ)

How many cameras do I need?
This depends on the terrain, the access to the house, and your security goals. A professional will plan all sightlines.

Do I need permission for a camera?
No—as long as you only monitor your own property. The GDPR and the BDSG regulate what is permitted.

Is a battery-powered camera sufficient?
For smaller properties or indoor areas, often yes – for permanent outdoor surveillance with 24/7 recording, permanently installed models make more sense.

Are my recordings safe?
Make sure you use encrypted connections, strong passwords, and regular updates. A professional can secure this.

Conclusion: Security through professional implementation

Professional installation of surveillance cameras not only offers increased security, but also convenience, quality, and legal certainty. Specialist companies plan, install, and configure your cameras individually – optionally with app integration, live access, storage solutions, and training.
