How much does an 8-channel PoE setup cost? Itemised breakdown
The recorder and hard drive account for 28% of the total cost, cameras 65%, and the switch 7%.So, “upgrading to better cameras” is the most effective upgrade; replacing the recorder will not improve image quality.

4-Channel, 8-Channel, 16-Channel: How Many Cameras Are Enough?
Count by “monitoring points”, not by dividing the floor area. For typical Hong Kong street-level shops, 4 to 6 cameras can generally cover 90% of risk points.
4 cameras for a 300 sq ft small shop; 6 for an 800 sq ft street-level shop; 8–10 for a 1,500 sq ft shop with storage. It is not recommended to buy a 16-channel system from the outset unless you already know you will expand within a year—a main unit with 8 channels plus cameras is much cheaper than replacing the entire system.
PoE cabling, WiFi battery, or 4G: which should you choose for a rented shop?
Renting a shop, do not want to drill into the walls, and have a lease of less than two years → 4G or battery-powered; owner-occupied shop and need uninterrupted 24/7 operation → PoE.
The most common mistake when renting a shop: buying a PoE kit only to discover when the installer arrives that the landlord does not allow drilling into concrete walls, or that the management office requires cables to be routed through existing conduits. The result is having to switch to 4G at the last minute—which means you bought the wrong kit.
To first understand the differences between models that do not require cabling, seeReolink battery and 4G camera lineup comparison; for the selection logic behind different EZVIZ models, seeEZVIZ Security Camera Buying Guide for Hong Kong 2026.
How many days can 2TB record? Calculating the retention period
With 2TB, 8 8MP cameras, H.265, and 6 Mbps, approximately 3.9 days can be recorded; keeping 30 days of footage requires at least 8TB or a lower bitrate.
Formula:可錄日數 = 硬碟 GB × 8,000 ÷ (bitrate Mbps × 3,600 × 24) ÷ 鏡頭數
Hong Kong shops generally need to retain footage for 14–30 days (missing cash, employee disputes, and insurance claims may only arise two or three weeks later). For 30 days of retention, use a system with 8TB or more, or reduce non-critical cameras to 4 Mbps while keeping a higher bitrate for critical areas.
How can I get clear images at night and at backlit checkout counters?
Night-time image quality depends on the image sensor and supplemental lighting, not the megapixel count.An 8MP camera can perform worse than a 4MP camera at a backlit checkout counter because each pixel is smaller and there is more noise.
Do not point the checkout camera directly toward the glass entrance—the backlight will make faces appear completely black. Instead, position it at a 45-degree angle, shooting downward from the ceiling. Full-color night-vision models are only effective in areas with streetlights or corridor lighting; a completely dark back alley still requires IR, and the image will appear in black and white. Adding a HK$200–400 supplemental light will generally improve night-time identification more than upgrading from 8MP to 12MP.
Hong Kong compliance: What should the notice say? Can employees be monitored?
A shop is a “data user”: it must have a lawful purpose, provide notification, and ensure that the scope is proportionate; the notice must state the monitoring purpose, the identity of the data user, and contact details.
Office of the Privacy Commissioner for Personal DataGuidance on CCTV SurveillanceThe guidance on organizations’ use of CCTV focuses on three key points: there must be a genuine need, monitoring must be conducted openly, and the scope of collection must be proportionate to the purpose. In practice, three measures should be implemented:
- Post a notice at the entrance: “This shop operates CCTV for security and loss-prevention purposes” + company name + contact details.
- Cameras should not be installed in employee rest rooms or changing areas. If employees need to be monitored in work areas, the purpose and handling procedures must be explained in the employee policy.
- State the retention period: “Recorded footage will be automatically overwritten after 30 days,” and include this in the privacy policy.
The above is a summary of general practices and does not constitute legal advice. For actual arrangements, please refer tothe full guidance from the Office of the Privacy Commissioner for Personal Dataor consult a lawyer.
4G Plan Monthly Fees and Data Usage: Actual Costs for Temporary Shops
4G camera hardware is priced similarly to PoE equipment, but monthly data charges are a variable cost; 24/7 cloud recording can quickly exceed your data allowance.
Two Reolink Go PT Ultra 4G cameras at HK$1,699 × 2 = HK$3,398, plus two 64GB cards at HK$480, for a total of HK$3,878. Set them to “record only when a person is detected + save to the card,” and monthly mobile data usage can be kept to a few GB; switching to 24/7 cloud recording will increase usage tenfold. SIM monthly fees vary considerably by telecommunications provider, so confirm with your provider.
Installation Pitfalls: Rented Shops, Older Buildings, and Typhoon Season
The five most common issues encountered on-site in Hong Kong that are rarely mentioned in quotations:
- Obtain approval from the landlord/management office before purchasing equipment.Written consent is required for drilling into concrete walls, routing cables along exterior walls, and using communal antenna conduits; residential-style shopping malls usually require the use of designated contractors.
- Without a suspended ceiling, surface-mounted wiring is required.Surface-mounted wiring requires cable trunking, which affects the shop’s appearance. It is best to complete it all at once before renovation.
- A power outlet is not the same as a PoE port.The switch should be placed in a well-ventilated location with a power supply; do not cram it under the checkout counter.
- Typhoon Season: Use stainless-steel outdoor brackets with waterproof sealant; do not use plastic cable ties. Check whether the angle has shifted after a typhoon.
- A power outage means recording stops immediately.For continuous recording, add a UPS for both the recorder and the switch.
