Therefore, comparing only resolution or nighttime recording performance is not enough; the recording area, privacy protection, wireless connectivity, mounting method, and storage structure should be reviewed as one system.\n\nIn particular, “drill-free” only means that no holes are made in the wall. It does not mean that issues involving the use of common areas, invasion of privacy, removal marks, or communication failures are resolved.\n\n## Recording Area and Privacy Issues\n\nA camera outside an apartment entrance may record not only visitors but also neighbors’ entry and exit times, direction of movement, companions, and daily routines. An angle that directly faces the door of the unit across the hall or broadly includes the elevator and stairs can easily collect more information than necessary for the installation’s purpose.\n\nIt is advisable to narrow the recording area in the following order.\n\n1. Define the area that needs to be monitored, such as where deliveries are placed or the space directly in front of the door.\n2. Tilt the camera downward rather than keeping it level so that distant parts of the hallway are not included.\n3. Use privacy masking to obscure the door across the hall, neighbors’ door locks, and elevator waiting areas.\n4. Play back both daytime footage and infrared nighttime footage to verify the masking boundaries.\n5. Test whether masking also applies to recorded footage, notification previews, and cloud thumbnails, not just the live view.\n\nPrivacy masking works differently depending on the product. Some methods merely overlay black areas on the screen, while others exclude those areas during storage. Some products may continue to detect motion in masked areas, so video masking and detection-zone exclusion must be configured separately.\n\n### Checking the Personal Information Protection Act and Management Rules\n\nThe Republic of Korea’s Personal Information Protection Act restricts the installation and operation of fixed video information processing devices in public places and, even when they are permitted, sets standards concerning manipulation beyond the stated purpose, changes to the recording area, audio recording, and other matters. The specific applicable provisions should be checked in the current statutes available through the Korean Law Information Center. However, which provisions apply to equipment installed by an individual household for security purposes may vary depending on the installation location, recording area, operator, and purpose of use.\n\nBefore recording a common hallway or attaching a device outside the entrance door, the following should be checked.\n\n- The apartment complex management rules and the management office’s standards for attaching equipment\n- Provisions in the lease agreement concerning facility alterations and restoration to the original condition\n- Whether the installation location is part of the privately owned area or a common area\n- Whether a recording notice is required and what information it must display\n- Whether audio recording can be turned off\n- Video access permissions for users other than family members and the retention period\n\nEven when the purpose is security, this does not automatically grant the right to continuously record more than is necessary. If there is a possibility of a dispute or a neighboring unit appears prominently in the frame, it is safer to confirm the specific installation conditions with the management body and a privacy protection authority.\n\n## Camera Angle and Privacy Masking Settings\n\nA wider lens angle makes it easier to capture nearby visitors, but it also includes more neighboring units and hallway space. Rather than looking only at the wide-angle specification, the actual installation height and lens direction should be evaluated together.\n\n| Inspection item | Desirable condition | Condition requiring caution |\n|---|---|---|\n| Unit across the hall | Excluded from the frame or fully masked | The entire door and people entering or leaving are recorded head-on |\n| Hallway length | Includes only the necessary area in front of the entrance | Continuously records as far as the elevator or stairs |\n| Delivery location | Items and approach movements can be identified | Items are placed in the blind spot directly beneath the camera |\n| Facial recording | Limited to the level needed to identify the purpose of a visit | Records every passerby head-on at close range |\n| Door lock display | Keypad and input actions are not visible | Password entry for a neighbor’s or the relevant unit’s lock is exposed |\n\nWith a mounting method in which the camera moves with the door when it opens, checking only the angle while the door is closed is not enough. The inside of a neighbor’s home may be recorded momentarily while the door opens and closes, or the device may collide with the wall, so footage of the actual operation should be reviewed.\n\n## Wi-Fi Effects of Steel Entrance Doors and Concrete Walls\n\nEven when entrance CCTV appears to be close to the router, connection quality can vary significantly because of steel entrance doors, reinforced concrete walls, electrical panels, and metal cabinets. In particular, because the camera is outside the door and the router is indoors, the signal path changes when the entrance door is closed.\n\nIn general, the 2.4GHz band is often better than 5GHz for passing through obstacles and reaching longer distances, but it may experience more interference from nearby routers and home appliances. 5GHz offers more available bandwidth, but its signal may weaken rapidly after passing through doors and walls. Actual results vary depending on the building structure and channel congestion.\n\nBefore installation, testing should reproduce the following conditions.\n\n- The entrance door is fully closed\n- The camera is placed at its final height and orientation\n- Nighttime recording and motion notifications are operating simultaneously\n- Family members are using the internet as usual\n- Both live viewing and the upload of recorded footage and arrival of notifications have been verified\n\nIt is difficult to judge stability based only on the Wi-Fi bars in the app. If live video repeatedly disconnects, the beginning of event footage is missing, or notifications arrive late, the connection quality may be insufficient.\n\nA repeater or mesh node should not be installed where the signal is already almost unavailable. It should be placed between the existing router and camera where it can reliably receive signals from both. Power outlets or communications equipment in common hallways must not be used without permission.\n\n## Drill-Free Installation and Restoration Standards\n\nDrill-free installation methods include magnets, over-the-door brackets, strong adhesive pads, and door-viewer replacement. Any of these methods may cause problems depending on the door structure and management rules.\n\n| Method | Advantage | Risk to check |\n|---|---|---|\n| Magnetic mounting | Easy to install and move | May fail to hold or may slip depending on the door material |\n| Over-the-door bracket | Some products do not require adhesive | May interfere with the door gap, rubber seal, or closing of the fire door |\n| Adhesive pad | Offers relatively flexible installation positioning | Paint may peel, adhesive residue may remain, or the device may detach at high temperatures |\n| Using the door viewer | Can reduce external protrusion | Owner consent may be required to modify existing components |\n\nRather than relying solely on claims that removal leaves no marks, test adhesive compatibility on a small area. Magnets or pads pressed against a surface for a long time can also leave discoloration or damage the paint. If the device falls and damages a person or property, separate liability issues may arise, so a fall-prevention mechanism is also necessary.\n\nIn jeonse or monthly rental housing, keeping written or text-message records of confirmation from the landlord and management office can help prevent disputes. The permitted installation location, whether adhesive may be used, replacement of the existing door viewer, and the scope of restoration upon moving out should be recorded specifically.\n\nOn a fire door, brackets and wires must not interfere with the door frame, door closer, locking mechanism, or rubber seal. After installation, repeatedly check that the door closes completely and locks on its own.\n\n## Comparing Continuous Recording and Motion-Triggered Recording\n\nThe recording method determines not only storage requirements but also the power source and the ability to review incidents. Battery-powered products are generally suited to motion-triggered recording, while continuous recording often requires wired power and a persistent network connection.\n\n| Category | Continuous recording | Motion-triggered recording |\n|---|---|---|\n| Recording coverage | Fewer gaps in time | Stores footage mainly around detected events |\n| Storage space | Consistently uses a large amount | Varies depending on foot traffic and sensitivity |\n| Battery | Places a heavy burden on battery-powered models | Relatively advantageous, but frequent notifications can drain the battery quickly |\n| Pre-event footage | Can be reviewed in continuous footage | The beginning of an approach may be missed without a pre-recording function |\n| Effect of false detections | Reflected consistently in storage use | Shadows, vehicle lights, and passing neighbors may increase storage use |\n| Data minimization | Unnecessary foot traffic is also recorded continuously | Narrowing the detection zone can reduce the amount recorded |\n\n### Calculating Storage Space and Retention Period\n\nThe theoretical daily storage requirement for continuous recording can be calculated using the average bitrate.\n\n`Daily storage (bytes) = Average bitrate (bps) × 86,400 seconds ÷ 8`\n\nFor example, if the average bitrate is 2Mbps, approximately 21.6GB per day is theoretically required. By a simple calculation, a 128GB storage device would hold about 5.9 days of footage, but the actual retention period may be shorter because of usable capacity, the file system, audio, metadata, and bitrate fluctuations.\n\nFor motion-triggered recording, it is difficult to calculate a fixed period from the specification sheet alone. The number of detections per day, the length of each recording, pre- and post-event buffers, resolution, codec, and hallway traffic all have an effect. A more accurate method is to measure the actual file sizes generated over several days after installation and recalculate the expected retention period.\n\nYou should also check whether the oldest footage is automatically deleted when the storage device becomes full, whether the app provides a warning before deletion, and whether memory card errors can be checked remotely. Important footage should be exported separately before it is automatically overwritten.\n\n## Pitfalls of Nighttime Recording and Motion Detection\n\nA clear daytime angle does not guarantee the same results at night. If infrared LEDs illuminate a nearby wall, door frame, or reflective surface, part of the image may become washed out while faces or the delivery location appear dark. Internal reflections may also occur in glass or a protective cover in front of the camera lens.\n\nMotion detection methods include analyzing pixel changes in the video and using PIR to detect changes in infrared radiation from people. Depending on the detection principle, the response may differ for a person approaching head-on, moving across the frame, or stopping in front of the door.\n\nReal-world testing should include the following situations.\n\n- A visitor approaches from either direction in the hallway\n- A person slowly approaches the camera head-on\n- A courier sets down a package and leaves immediately\n- The hallway lights turn on or off\n- The elevator door or a neighbor’s door opens\n- The camera’s direction changes while the entrance door is being opened\n\n## Security and Service Discontinuation Issues Easily Overlooked When Choosing a Product\n\nEntrance CCTV is both a recording device and an internet-connected IoT device. Even if stored footage is encrypted, it may be accessed externally if the account password is compromised or sharing permissions remain active.\n\nThe following items should be checked before and after installation.\n\n- Whether the manufacturer discloses the period during which security updates will be provided\n- Whether multi-factor authentication can be enabled for the account\n- Whether the default password or a reused password has been changed\n- Whether separate permissions can be assigned to each family account\n- Whether login history and new-device login notifications are provided\n- Where the original footage remains, in local storage or cloud storage\n- How video access and deletion are handled after a cloud subscription ends\n- Whether the account connection and storage device can be reset before transferring or disposing of the product\n\nWhen selling the device secondhand or moving, simply removing the camera from the app may not be enough. The memory card should be removed and erased, the device should be factory-reset, and any footage and shared accounts remaining in the cloud should be handled separately.\n\nIn addition, if the manufacturer’s cloud service is discontinued, remote viewing and notifications may no longer work even if the camera hardware is functioning normally. Before purchasing, it is worth checking whether basic functions can be maintained with local storage alone and whether a specific subscription is required to export footage.\n\n## Final Pre-Installation Checklist\n\n- Have you defined the recording purpose and the area that must be visible?\n- Have you excluded the unit across the hall, door locks, and elevator from the frame?\n- Does privacy masking apply to recorded footage and notification images as well?\n- Can audio recording be disabled?\n- Have you checked the attachment and restoration conditions in the management rules and lease agreement?\n- Have you tested live video and event uploads with the door closed?\n- Do brackets or wires interfere with the fire door’s ability to close completely?\n- Have you checked for nighttime infrared reflections and the blind spot directly beneath the camera?\n- Have you tested the storage device’s actual retention period and automatic overwrite method?\n- Have you checked multi-factor authentication, updates, shared accounts, and the device reset procedure?\n\n## Frequently Asked Questions\n\n### Is it permissible to record the common hallway outside an apartment entrance with personal CCTV?\n\nA security purpose alone does not automatically permit all recording. Restrictions under the Personal Information Protection Act may apply to fixed video information processing devices in public places, and the legality of an individual installation varies depending on the recording area and purpose, installation location, and operator. Check the management rules and minimize the recording area so neighboring units are not continuously recorded.\n\n### Is landlord consent unnecessary if the installation is drill-free?\n\nNot always. Adhesive or magnets may damage the door’s paint, an exterior device may extend into a common area, and replacing the door viewer may constitute a modification to existing facilities. It is safer to check the lease agreement and management rules and document the permitted scope and restoration conditions.\n\n### Why does Wi-Fi work well inside the entrance door but disconnect outside?\n\nA steel entrance door and reinforced concrete can weaken radio signals between the router and camera. Measurements taken with the door open do not reflect actual usage conditions, so test video uploads and notifications at the final installation location with the door closed.\n\n### Which band is more suitable, 2.4GHz or 5GHz?\n\nAt entrances with many obstacles, 2.4GHz is often more stable, but it may experience significant nearby interference. 5GHz may offer advantages in speed and congestion, but it tends to weaken after passing through walls and doors. The choice should be based on the bands supported by the camera and the connection quality at the actual installation location.\n\n### If privacy masking is configured, does that mean footage of neighbors is not stored?\n\nIt depends on the product. Masking may appear only in the live view, or it may apply to recorded footage while the masked area is still used for motion analysis. Recorded footage, notification thumbnails, cloud footage, and detection-zone settings should each be tested separately.\n\n### How many days of footage can be stored on a 128GB memory card?\n\nResolution alone does not determine this. Average bitrate, codec, audio, frame rate, and recording method all have an effect. Under the simple assumption of continuous recording at an average of 2Mbps, the theoretical period is approximately 5.9 days, but the actual retention period may be shorter because of usable capacity and bitrate fluctuations.\n\n### Can a battery-powered camera record continuously?\n\nSome products do not support this feature or provide continuous recording only while connected to power. Battery-powered models are generally designed for motion-triggered recording, and foot traffic, low temperatures, live video use, and weak Wi-Fi signals can increase battery consumption.\n\n### Is it permissible to use audio recording as well?\n\nAudio recording by fixed video information processing devices may be subject to strict restrictions under the Personal Information Protection Act. Because entrance cameras can easily capture conversations unintentionally, the microphone and audio recording should be turned off by default. If audio is necessary, the applicable laws and specific operating conditions should be checked separately.\n\n### Which is safer, cloud storage or memory card storage?\n\nNeither is always safer. Cloud storage may preserve footage even if the camera is damaged or stolen, but it carries risks of account compromise and service discontinuation. A memory card can reduce external transmission, but it may be lost with the device or fail. Encryption, multi-factor authentication, and export and deletion procedures should also be compared.","content_html":"\u003cp\u003eApartment entrance CCTV can be used to investigate missing deliveries or intrusions, but the camera usually points toward a common hallway.

After removing the device from the app, perform a factory reset, and address any adhesive residue and mounting marks on the door or wall in accordance with the restoration requirements under the contract."}],"sources":[{"url":"https://www.law.go.kr/법령/개인정보보호법","title":"National Law Information Center Personal Information Protection Act","type":"source"},{"url":"https://www.adtcaps.co.kr/caps-story/blog/entrance-cctv-installation-guide","title":"Caps Home Front Door CCTV Installation Guide","type":"source"},{"url":"https://inganyoyo.tistory.com/119","title":"Apartment Front Door CCTV Installation Case Materials 1","type":"source"},{"url":"https://inganyoyo.tistory.com/121","title":"Apartment Front Door CCTV Installation Case Materials 2","type":"source"},{"url":"https://inganyoyo.tistory.com/125","title":"Apartment Front Door CCTV Installation Case Materials 3","type":"source"}],"images":[{"id":1025,"url":"https://injoys.com/rails/active_storage/blobs/proxy/eyJfcmFpbHMiOnsiZGF0YSI6MTQzNTUsInB1ciI6ImJsb2JfaWQifX0=--f31f8cf628df021f1fc57f040712623cf129608c/ai-59d84f95.webp","is_representative":true,"generation_method":"ai_photo","license":"ai_generated","mime_type":"image/webp","translations":{"ko":{"alt":"아파트 현관문 카메라와 태블릿의 CCTV 화면을 점검하는 남성","caption":"남성이 현관문에 설치된 카메라의 위치와 실시간 화면을 확인하고 있다.","description":null},"en":{"alt":"Man checking a door-mounted security camera and its CCTV feed on a tablet","caption":"A man verifies the camera position and live view at an apartment entrance.","description":null},"ja":{"alt":"玄関ドアの防犯カメラとタブレットの映像を確認する男性","caption":"男性が玄関ドアに設置されたカメラの位置と映像を点検している。","description":null},"es":{"alt":"Hombre revisando una cámara de seguridad en la puerta y su imagen en una tableta","caption":"Un hombre comprueba la posición de la cámara y la vista en directo en la entrada del apartamento.","description":null},"id":{"alt":"Pria memeriksa kamera keamanan di pintu dan tayangan CCTV pada tablet","caption":"Seorang pria memeriksa posisi kamera dan tayangan langsung di pintu masuk apartemen.","description":null},"pt":{"alt":"Homem verificando uma câmera de segurança na porta e a imagem em um tablet","caption":"Um homem confere a posição da câmera e a transmissão ao vivo na entrada do apartamento.","description":null},"zh-hant":{"alt":"男子檢查公寓門上的監視器及平板電腦中的即時畫面","caption":"男子正在確認公寓玄關監視器的位置與即時影像。","description":null},"de":{"alt":"Mann prüft eine Türkamera und deren Überwachungsbild auf einem Tablet","caption":"Ein Mann kontrolliert die Kameraposition und das Livebild am Wohnungseingang.","description":null}}},{"id":1026,"url":"https://injoys.com/rails/active_storage/blobs/proxy/eyJfcmFpbHMiOnsiZGF0YSI6MTQzNjEsInB1ciI6ImJsb2JfaWQifX0=--c4c0a254a1a94c6c8f42828770dc659315f5afb2/ai-7b61597e.webp","is_representative":false,"generation_method":"ai_image","license":"ai_generated","mime_type":"image/webp","translations":{"ko":{"alt":"아파트 현관문 CCTV의 촬영 범위와 와이파이, 배터리, 저장공간, 보안 점검 항목을 나타낸 도해","caption":"현관 CCTV 설치 전에 촬영 범위와 연결 상태, 전원, 저장공간, 보안을 점검하는 장면이다.","description":null},"en":{"alt":"Diagram of an apartment door CCTV covering a package, with Wi-Fi, battery, storage, and security checks","caption":"The diagram shows key checks before installing door CCTV, including coverage, connectivity, power, storage, and security.","description":null},"ja":{"alt":"荷物を撮影する玄関ドアCCTVとWi-Fi、電池、保存容量、セキュリティーの点検図","caption":"玄関CCTVの設置前に撮影範囲や接続、電源、保存容量、セキュリティーを確認する図です。","description":null},"es":{"alt":"Diagrama de CCTV en una puerta de apartamento con controles de cobertura, Wi-Fi, batería, almacenamiento y seguridad","caption":"El diagrama muestra qué revisar antes de instalar el CCTV: cobertura, conexión, energía, almacenamiento y seguridad.","description":null},"id":{"alt":"Diagram CCTV pintu apartemen yang memantau paket serta pemeriksaan Wi-Fi, baterai, penyimpanan, dan keamanan","caption":"Diagram ini menunjukkan pemeriksaan cakupan, koneksi, daya, penyimpanan, dan keamanan sebelum memasang CCTV pintu.","description":null},"pt":{"alt":"Diagrama de CCTV na porta de apartamento com verificações de cobertura, Wi-Fi, bateria, armazenamento e segurança","caption":"O diagrama mostra o que verificar antes da instalação: cobertura, conexão, energia, armazenamento e segurança.","description":null},"zh-hant":{"alt":"公寓門口CCTV監看包裹，並標示Wi-Fi、電池、儲存空間與安全檢查項目","caption":"圖中呈現安裝門口CCTV前應檢查的拍攝範圍、連線、電力、儲存空間與安全性。","description":null},"de":{"alt":"Schaubild einer Wohnungstür-Kamera mit Prüfungen zu Sichtfeld, WLAN, Akku, Speicher und Sicherheit","caption":"Die Grafik zeigt wichtige Prüfungen vor der Montage: Sichtfeld, Verbindung, Stromversorgung, Speicher und Sicherheit.","description":null}}}],"published_at":"2026-09-03T03:50:25+09:00","updated_at":"2026-09-03T03:50:25+09:00","license":"cc_by","translation_status":"reviewed","available_locales":["ko","en","ja","es"],"data_locales":["ko","en","ja","es","id","pt","zh-hant","de"],"url":"https://injoys.com/en/articles/apartment-entrance-cctv-installation-checklist"}
