Plan shop CCTV around the till, entrance and stock routes before choosing cameras, an NVR and storage. In a Hong Kong retail shop, usable evidence depends on the actual view, accurate time and available recordings. Resolution and camera count alone do not answer those questions.
Give each viewpoint a job
| Position | Task | Test on site |
|---|---|---|
| Till | Record handovers and counter activity | Body obstruction, lighting and payment-screen privacy |
| Entrance | Show entry and exit direction | Glass reflections, daylight contrast and shutters |
| Stock aisle | Show movement and stock handling | Shelf height, corners and changing displays |
| Receiving area | Check delivery time and handovers | Backlight, weather and evening lighting |
For a compact shop, entrance overview, counter detail and a stock aisle can be three planning tasks. They are not a prescribed three-camera package. Test representative movements without collecting unnecessary customer payment information.
Choose the recording arrangement first
Compare PoE and a compatible NVR when cabling is practical and several fixed views need recording. A plug-in indoor Wi-Fi camera with compatible local storage may suit a single position with reliable power and reception. Check battery-camera recording modes separately before relying on a complete timeline. See the PoE camera and NVR planning guide and event, pre-recording and continuous recording comparison.
Relevant store products to shortlist
- Reolink Duo 3 PoE 16MP 180° for a wide fixed overview, with a separate assessment of identification detail.
- Reolink TrackMix PoE 4K when dual views and tracking suit the position; retain fixed coverage of other important areas.
- Reolink E1 Zoom 4K 8MP for a powered indoor position where optical zoom and microSD recording suit the task. This is the 4K 8MP version.
- Reolink NVS8 with 2TB HDD as a central recording starting point. Check exact hardware, cameras, power and retention before treating any selection as a compatible system.
Size storage for the required retention
Four cameras averaging 4Mbps each need about 5.184TB of video-only decimal storage for 30 continuous days, before audio, files and system overhead. This is a worked example, not a measured bitrate for the recommended models. Set a justified retention period, then use the CCTV recording-days and capacity guide. Export relevant incident clips promptly through authorised accounts.
Restaurants and offices need additional checks
Keep cameras away from steam, grease and heat; an indoor camera is not weatherproof simply because it is sheltered. Separate building security from employee monitoring. Explain monitoring arrangements, restrict access and set retention. Review PCPD workplace guidance and assess audio separately. Toilets, changing and private rest areas need particular care.
Prepare an ordering and acceptance checklist
- Provide day and night location photos, the task and approximate viewing distance.
- List camera positions, cable routes, network and power.
- Specify recording mode, retention, playback and export needs.
- Assign live-view, playback, download and administration permissions; revoke former staff access.
- Check itemised equipment, storage, cabling, accessories and service costs against the actual scope.
Frequently asked questions
Will a 4K till camera always read banknotes?
No. Angle, distance, obstruction, lighting and movement affect the result. Test the actual view.
Will recording continue without internet?
A configured local recorder or card may continue if the required local connections and power remain. Test internet loss separately from power or local-network failure.
Does every shop need a cloud subscription?
No. Compare local and cloud recording costs while allowing for equipment, maintenance and connectivity.
Browse shop security cameras or read the warehouse and receiving-area CCTV guide.
