Direct answer: prepare a short brief before choosing models
Before your first CCTV order, prepare the viewing positions, main purpose, approximate distances, available power and network, required recording and intended users. If you already own equipment, add its full model and hardware information. You do not need an engineering drawing or account passwords. A clear brief helps distinguish a suitable camera from one that merely looks similar.
This checklist is for Hong Kong households and small businesses comparing equipment online. It helps you prepare an enquiry and check a basket; it is not an installation survey or a pre-approved camera package. Camera quantity, compatibility, recording duration and service scope still need confirmation for the selected products.
1. Give each proposed view a job
Write one line for each position. “Living room: check the pet near the resting area” is more useful than “one indoor camera”. “Entrance: see a visitor at the door” is different from watching the whole front yard. Decide whether you need an overview, a particular route or closer detail at one place. Note the approximate target distance and anything likely to block the view.
A rough floor sketch is enough to start. Mark walls, closed doors, shelves and glass. Take suitable daytime and evening location photos if helpful, keeping unrelated people and private information out of them. Do not assume that one wide-angle or turning camera records every direction with the detail you need. Use the room-by-room camera buying guide to decide whether several tasks can share a useful viewpoint.
2. Describe the location, not just “indoor” or “outdoor”
For an outdoor position, note rain, direct sun, mounting access and whether the equipment can be maintained safely. For a kitchen or work area, note heat, steam, dust and grease. A roof above a camera does not automatically make an indoor model appropriate. The exact product’s environmental and mounting conditions remain the reference.
Check permission to mount equipment before paying for a camera that depends on drilling or changing a door. Door viewers need matching door dimensions and an appropriate fixing arrangement. Shared corridors and neighbouring windows need careful framing and relevant management checks. Camera purchasing and permission to install are separate questions; the doorway CCTV guide explains the location issues.
3. List power and internet as separate entries
For each position, write down whether there is a suitable socket, an approved fixed supply, a PoE power route or a practical charging arrangement. Then identify Wi-Fi coverage, Ethernet or a mobile-data connection. A Wi-Fi camera may still need an adapter. An Ethernet socket does not establish PoE support. A battery does not power the router during a mains outage.
If there is no fixed broadband, compare 4G camera requirements and account for a compatible SIM, data service and local signal. For a cable-based system, record the intended switch or recorder and use the PoE port and power-budget checklist. Do not choose a power accessory solely because its plug fits.
4. Decide what you need to do with recordings
Write separate requirements for live viewing, recording, playback, notifications and export. Wanting to check a room occasionally is different from needing a continuous incident timeline. Decide a justified retention target and who will retrieve footage. A phone notification does not prove that the matching recording exists.
Compare supported camera-card recording, a compatible recorder or hub, and cloud services. The available route depends on the exact camera. If you choose a cloud plan, check supported cameras, service region, retention, activation and any recurring charge. A free viewing app does not mean every recording service is free. The local versus cloud recording guide helps separate these choices.
For capacity planning, use the recording mode and actual bitrate rather than a universal promise that a card saves a fixed number of days. Audio, overhead and usage can affect the result. Read the recording-days and storage explanation before choosing a card or hard drive.
5. If you already have equipment, identify it precisely
For an existing recorder, note the full model, hardware revision and firmware, current camera list and occupied channels. For an existing hub, check the matching manufacturer support list. A brand name on a box is insufficient to confirm every current camera or recording function. Keep important footage protected before planning configuration changes.
The new-camera and old-NVR checklist explains what to collect. When comparing separate memory cards with central storage, use the Home Hub and NVR guide. Do not send device passwords, verification codes or full identity labels in public comments.
6. Agree who will own and use the system
Choose an account owner who can maintain recovery access. List who needs live view, playback, audio, export and settings changes. These are different permissions; they may not be separately selectable on every product. A model without the required sharing controls may be a poor choice even if its picture specification suits the room.
Where supported, use separate invited accounts or appropriate device-user roles. Do not assume a basic device-sharing method is view-only. Check the exact model, app and firmware against the manufacturer instructions and confirm the permissions actually granted. Start with the camera account and family-sharing checklist before giving anybody access.
7. Review the basket one item at a time
For every line, confirm the full model, version, quantity, package contents and required accessories. Ask whether storage, a disk, power adapter, compatible panel or mounting item is included. An illustration showing several items does not by itself establish the supplied package. Refer to the actual product listing and confirmed order details.
Compare the total of the necessary equipment and any applicable recurring service. Include confirmed delivery charges and separately agreed work where relevant. Do not treat a camera price as an installed-system quotation or assume that buying several models creates one compatible set. Unknown availability or prices need confirmation rather than a guessed number.
Product directions can be shortlisted through security cameras by use and recorders and camera accessories. If an indoor view, doorway and outdoor position require different models, keep their requirements on separate lines.
8. Plan the first-use check before permanent mounting
Prepare to check the actual saved footage, not only the live picture. Confirm time, recording schedule, playback and an authorised export. Check day and night framing, then notification delivery on the intended phones. For a business, assign responsibility for recording-health checks and account access.
If you require operation through an internet or power interruption, identify which equipment must remain working and arrange a safe authorised check. Do not unplug equipment during critical recording or reset a device before protecting important clips. Use the power-cut dependency checklist to distinguish camera power, local recording and remote access.
Copy this enquiry checklist into your notes
Location and task: the positions to cover, their main purpose and approximate distance. Conditions: day/night light, obstacles, weather and permitted mounting. Power and network: available supply, Wi-Fi or Ethernet, or mobile service. Recordings: required mode, storage route, retention target and export. People: owner and required access. Existing equipment: full model, hardware and firmware. Order: proposed quantities, included items and unresolved questions.
Provide only information necessary to assess the equipment. Keep passwords, verification codes, identity details and unrelated private footage out of the enquiry. If a detail is unknown, mark it “to confirm”. That is more useful than describing a different version or assuming a feature is standard.

Prepared on 29 October 2026 from manufacturer support information and existing model-specific buying guides. This is a proposed purchasing workflow, not a field test, installation service promise or compatibility approval for every product linked. Current supply version, package, warranty and service terms must be checked on the relevant product and order.
