⚠️ Indoor Camera Privacy Precautions: Indoor cameras also concern family privacy. Installation in bedrooms, bathrooms, or toilets may violate privacy and should be strictly avoided. Additionally, prior notice is required for installation in workplaces with employees.
Can one camera be used for both outdoor and indoor?
Cameras labeled as "indoor/outdoor compatible" have IP65 or higher waterproof performance and can be used both outdoors and indoors. However, indoor-specific models often have more features for indoor use, such as design, size, two-way audio, and privacy shutters.
- If you want to use one camera for both indoor and outdoor: Choose a model that has IP65 or higher outdoor compatibility, PTZ function, and two-way audio to cover all needs with one device.
- If you prioritize cost-effectiveness and use separate cameras: Using dedicated outdoor models for entrances and parking lots, and dedicated indoor models for indoor monitoring, allows for optimization for each purpose.

Frequently Asked Questions (FAQ)
Is it okay to install an indoor camera outdoors?
Installing an indoor-only camera outdoors is not recommended. Without waterproof performance, there is a risk of internal circuit failure due to rain, dew, or humidity. Always choose a model with IP65 or higher waterproofing for outdoor installation.
Is it okay to install an outdoor camera indoors?
Technically, there's no problem, but outdoor cameras are generally larger and have a more robust design compared to indoor-only models, which might not blend well with indoor interiors. If you opt for an indoor/outdoor compatible model, there are designs that are more suitable for indoor placement.
How many security cameras are enough?
For a typical detached house, the front entrance, back door, and parking lot are the minimum coverage points. A PTZ (360° rotation) compatible camera can cover a wide area with just one unit, reducing the number of cameras needed. If the purpose is indoor monitoring, you might want to add cameras for each room you wish to monitor.
How should outdoor camera wiring be done?
For wireless (Wi-Fi) cameras, the only cable is the power cable to the outlet. If there's no outdoor outlet, you can run the cable from indoors through a hole in the exterior wall, or choose a solar panel-compatible model. If wiring work requiring a qualified electrician is necessary, please contact a professional.
Will outdoor cameras break in winter cold or summer heat?
Outdoor-compatible models generally support operating temperatures between -20℃ and 50℃. In Japan's climate, this range is usually sufficient. However, on south-facing walls exposed to direct sunlight for extended periods, the camera's internal temperature can rise easily, so it is recommended to install it in a location that avoids direct sunlight if possible.
Summary: Outdoor needs IP waterproofing/night vision, Indoor needs wide-angle/two-way audio
When choosing a security camera, prioritize checking for IP65 or higher waterproofing, night vision, and high resolution for outdoor installation, and wide-angle, two-way audio, and a privacy shutter for indoor installation.
