What does an 8-camera CCTV system cost?
Hardware is 100% of what you pay us; installation is a separate contract with a licence holder. The split matters because most quotes you receive online bundle the two and hide the labour line.
| Item | Model | Qty | Unit (HKD) | Unit (SGD) | Subtotal (SGD) |
|---|---|---|---|---|---|
| 8-channel PoE NVR, 2TB | Reolink NVS8-NHD | 1 | HK$2,599 | S$424 | S$424 |
| 8MP PoE camera |  Reolink P330 | 8 | HK$749 | S$122 | S$977 |
| 120W PoE switch |  Reolink POE SWITCH 120W | 1 | HK$599 | S$98 | S$98 |
| Hardware total | S$1,498 | ||||
Three common variations:
| Config | Contents | Hardware (SGD) | Retention at 6 Mbps |
|---|---|---|---|
| 4 cameras | Same 8-ch NVR + 4 × P330 + switch | ≈S$1,010 | 7.9 days |
| 8 cameras | 8-ch NVR + 8 × P330 + switch | ≈S$1,498 | 3.9 days |
| 12 cameras | 16-ch NVR (4TB) + 12 × P330 + switch | ≈S$2,149 | 2.6 days |
| 8 cameras, colour night | 8-ch NVR + 8 ×  CX810 + switch | ≈S$1,954 | 3.9 days |
Hardware prices were read from our product database on 2026-10-26 and converted at 1 HKD = 0.1630 SGD (mid-market, 2026-10-25). SGD figures are indicative: the checkout price on the Singapore storefront governs. Excludes shipping, cabling, brackets, conduit and labour.
How many cameras does a shop actually need?
Count exposure points, not floor area. Four to six cameras cover about 90% of the risk in a typical shop.
| Position | Why it needs its own camera | Priority |
|---|---|---|
| Entrance (facing out) | Captures the person before they enter — face, clothing, companions | Essential |
| Cashier (angled down) | Must see notes, hands and screen in one frame | Essential |
| Main aisle | One every 8–10 m; shelving creates blind spots | High |
| Back door / service yard | Staff movement, deliveries, waste and shrinkage | High |
| Stockroom door | High-value stock movement | Medium |
| Loading bay / parking | Delivery disputes and damage claims | Medium |
A 300 sq ft unit needs 4. An 800 sq ft shop floor needs 6. A 1,500 sq ft unit with a stockroom needs 8–10. Do not start at 16 channels unless expansion is already planned — an 8-channel NVR with spare ports is far cheaper than replacing the unit.
PoE, wireless battery, or 4G — which fits a Singapore shophouse?
Leased unit with a short term and no drilling rights: 4G or battery. Owned unit needing 24/7 recording: PoE.
| PoE wired | Wi-Fi battery | 4G cellular | |
|---|---|---|---|
| 8-camera hardware | ≈S$1,498 | ≈S$1,470–2,120 | ≈S$2,120–2,930 |
| Cabling required | Yes — ceiling or wall runs | None | None |
| 24/7 continuous recording | Yes | Usually event-only | Data-limited |
| During a power cut | Only with a UPS | Battery keeps running | Depends on the cell site |
| Monthly cost | S$0 | S$0 | SIM data plan, varies by telco |
| Best for | Owned shop, office, warehouse | Leased shop, tuition centre | Pop-up, site office, market stall |
Conservation shophouses add a constraint that does not exist in most markets: high ceilings make wireless replacement trips awkward, and heritage rules restrict where you can drill. Check the URA conservation guidelines for your building before ordering anything.
How many days will 2TB hold?
2TB, eight 8MP cameras, H.265 at 6 Mbps: about 3.9 days.
Formula: days = disk GB × 8,000 ÷ (bitrate Mbps × 3,600 × 24) ÷ cameras
| Bitrate | 2TB total hours | 8 cameras | 4 cameras |
|---|---|---|---|
| 4 Mbps | 1,138 h | 5.9 days | 11.9 days |
| 6 Mbps | 759 h | 3.9 days | 7.9 days |
| 8 Mbps | 569 h | 3.0 days | 5.9 days |
Most Singapore shops need 14–30 days of retention because disputes surface weeks later — an insurance claim, a staff incident, a chargeback. Buy 8TB or more, or drop the aisle cameras to 4 Mbps and keep the cashier and entrance at a higher bitrate.
Do I need approval before installing?
Inside your own unit you generally do not. Anything on common property does. The rules depend on the property type:
| Situation | Rule |
|---|---|
| Camera inside an HDB flat facing the corridor | HDB approval no longer required since May 2023, but the camera must not face a neighbour's door or windows |
| Camera outside the unit (corridor, common area) | Town Council authorisation required; a police report is normally asked for first; approval typically takes 1–2 weeks; the approval is time-limited (commonly 6 months) and must be renewed |
| Unauthorised fixture on common property | Fine of up to S$5,000 |
| Condominium unit | Governed by MCST by-laws — check your estate's rules |
| Landed property | You may install within your own compound |
| Toilets and changing rooms | Never — installation can amount to a criminal offence |
This is a working summary, not legal advice. Confirm with your Town Council, MCST or a lawyer before you buy hardware for a common-property location — the approval can change the whole design.
Does PDPA apply to shop CCTV?
Yes, if your shop is an organisation capturing identifiable individuals. Three duties matter in practice:
- Notice. Put up a sign at the entrance stating the purpose, the identity of the organisation operating the cameras, and a contact for privacy enquiries. A picture of a camera alone is not enough.
- Consent. For premises open to the public, consent is generally not required for publicly observable data, but notice is still good practice. For restricted premises — offices with card access, staff-only back rooms — notices and consent obligations are stricter.
- Retention and access. Keep footage no longer than the purpose requires, write the retention period into your policy, and have a process for access requests — including masking other individuals in the footage.
The Act itself is at sso.agc.gov.sg/Act/PDPA2012; the regulator is the Personal Data Protection Commission.
Who is allowed to install it?
In Singapore, CCTV installation is a licensable security service. Under the Private Security Industry Act, a person providing installation services must hold a Security Service Provider licence. Ask for the licence before paying a deposit — and check that the person on site is covered by it, not just the company that answered the phone.
We sell hardware and configuration advice only. We do not install, and we do not take a cut from any installer — which is why you can put our bill of materials in front of three licence holders and compare labour on equal terms.
