Resolution and field of view
For an indoor camera covering a hallway or living room, 1080p (Full HD) is generally sufficient. 2K and 4K cameras produce larger files and require more storage or bandwidth, without always adding meaningful detail in typical indoor lighting conditions.
Field of view (FoV) matters more than resolution in small rooms. A 130° diagonal FoV covers most of a standard room from a corner position. Cameras with a narrower FoV (under 100°) may miss the edges of the room even when mounted optimally. Check the manufacturer's spec sheet — some brands list horizontal FoV, others diagonal, which are not directly comparable.
Night vision
Infrared (IR) night vision is standard at every price point. Better cameras add a colour night vision mode that uses a brief white-light LED or sensor amplification to produce colour footage in low light. IR footage is monochrome but invisible to occupants; colour night vision is more informative but the LED flash may be noticeable.
For Polish apartments with blackout curtains in winter, colour night vision is worth checking. The Reolink E1 Pro and Netatmo Indoor Camera both offer it in the sub-500 PLN range.
Cloud versus local storage
Most consumer cameras default to cloud storage. Footage is uploaded to the manufacturer's servers and you access it via the app. This is convenient but creates several concerns for Polish users:
- Data residency: Where are the servers? GDPR requires that data on EU residents stored outside the EU meets adequacy requirements. Check the manufacturer's privacy policy for the server location. Netatmo (owned by Legrand, France) stores data in Europe. Some Chinese-brand cameras store data on servers in China without a clear EU data-processing addendum.
- Ongoing cost: Cloud subscriptions for footage history typically cost 5–20 EUR per month per camera. This cost is rarely mentioned in product listings.
- Service discontinuation: Several camera brands have shut down cloud services, rendering hardware useless. Ring, Nest, and Arlo have all restructured their subscription terms significantly since 2022.
Cameras that support local storage via microSD card or NAS (Network Attached Storage) avoid these issues. Reolink, Hikvision, and ANNKE all offer local-first models. Home Assistant's camera integration supports RTSP streams from local cameras, allowing recordings to be stored on your own hardware.
GDPR considerations for home use in Poland
Recording inside your own home is generally not subject to GDPR — you are not processing data of others in a systematic way. However, a camera positioned to capture a shared building corridor, stairwell, or public area outside your property window is a different situation. The Polish data protection authority (UODO — Urząd Ochrony Danych Osobowych) has issued guidance that even private camera installations capturing shared building spaces may require informing residents and potentially registering processing activities.
If your camera's FoV extends beyond your own front door, consider repositioning it or using masking zones (available in most modern camera apps) to blur or exclude areas outside your property.
Motion detection and alerts
Basic motion detection triggers on any change in the video frame — wind moving curtains, light changes, or a cat walking past. Better cameras use person detection (AI-based, typically on-device or in cloud) to reduce false alerts. At the time of writing, the following models offer reliable person detection without a paid subscription:
- Reolink E1 Outdoor Pro: On-device person and vehicle detection. No subscription required. RTSP stream available.
- Hikvision DS-2CD2143G2-I: AcuSense technology with person/vehicle classification. Primarily a prosumer model, but widely available in Poland through installers and online.
- Netatmo Indoor Smart Security Camera: Facial recognition for registered household members. Stores footage locally on an included microSD card. GDPR-compliant storage for EU users.
Power and placement
Indoor cameras are powered via USB-C or micro-USB, or in the case of some PoE (Power over Ethernet) models, a single Ethernet cable. USB-powered cameras are easiest to place, but the cable must reach a socket — consider this when planning mounting positions. Ceiling mounts are aesthetically cleaner but require routing a cable through the ceiling or along a cable channel.
PoE cameras are worth the extra complexity in a new build or renovation: a single Cat6 cable carries both power and data, there is no Wi-Fi dependency, and the connection is more stable. Hikvision and Reolink both sell PoE cameras with matching NVR (Network Video Recorder) kits at around 1000–1500 PLN for a 4-camera setup.
Offline behaviour
Test what happens when your internet connection drops. A camera that records only to the cloud stops recording entirely when offline. Local-storage cameras continue recording to the SD card. This distinction matters for holiday homes or apartments in areas with less reliable ISPs.
For the most resilient setup: a PoE NVR system with local drives operates completely independently of the internet. Remote access is possible via a VPN tunnel to your home network rather than through a manufacturer cloud.
