PoE（Power over Ethernet）is the most practical solution for wired CCTV: one network cable supplies both power and data, so there is no need to look for a power outlet near the ceiling, and you won't have to worry about Wi-Fi disconnections. Below are the current prices of the PoE cameras and NVRs in stock at our store, plus three complete bundles starting from HK$429.
30-second conclusion:Installing just one camera and want the lowest price → P324（HK$429）＋memory card; 4 cameras for an SME or village house → NVS4（HK$830）＋4 P320 cameras（HK$569）; need 4K to identify license plates and faces → NVS8＋P330. All are PoE, so no additional power wiring is required.
1. What problems does PoE solve?
- No need for additional power wiring:With traditional CCTV, every camera needs a 13A power outlet or power adapter, and outdoor installations also require a waterproof box; PoE only requires one network cable, with power supplied by the switch／NVR.
- No worries about Wi-Fi going down:Wired connections offer stable latency and won't disconnect because neighbors are occupying the 2.4G channel.
- One cable can reach 100 meters:Cat5e／Cat6 has a standard transmission distance of 100 meters, which is sufficient for most homes, village houses, and shops.
- Centralized management:The NVR records footage from multiple cameras at once and lets you view everything through one interface; if something goes wrong, there is no need to remove the memory card from each camera one by one.
2. What do you need to buy? A checklist

6. Cabling in Practice: 3 Things You’ll Definitely Regret
- Network cables are too short / the routing is wrong:Draw a plan before buying cables. Leave 2–3 metres of spare cable for each camera, and do not run outdoor sections through the same conduit as power cables.
- Outdoor connections are not waterproofed:Exposed RJ45 connectors will oxidise within six months. Use waterproof connectors or junction boxes, with the connection point facing downward.
- The NVR is placed in an unair-conditioned storage room:Hard drives can fail prematurely when exposed to high temperatures for long periods. Place the NVR in a well-ventilated area, and do not keep the door closed in summer.
7. Recording Capacity: How Large Should the Hard Drive Be?
Approximate formula:Daily GB per camera ≈ Bitrate (Mbps) × 10.8。Based on 4MP／4Mbps, one camera uses approximately 43GB per day; 4 cameras recording for 30 days require approximately 5.2TB, so choose at least 6TB or enable motion-detection recording. Enabling 「Record only when events occur」 can save 70–80%.
8. Frequently Asked Questions
Can PoE cameras be used with a regular switch?
You need a PoE switch or PoE injector to supply power. A regular switch only transmits data, so the cameras will not turn on. Before buying, check whether the ports support 802.3af／at.
Does the NVR have to be the same brand?
Using the same brand is recommended. Reolink cameras are plug and play when connected to a Reolink NVR; with mixed brands, ONVIF support is required, setup is more complicated, and some features such as AI detection may not be available.
Can PoE and Wi-Fi cameras be used together?
Yes, but they generally need to be recorded separately. NVRs usually only accept wired cameras or specified wireless models; using both types typically requires two systems or software that supports RTSP, such as Synology Surveillance Station.
Do outdoor village houses need lightning protection?
For exposed village houses and rooftop installations, adding a PoE surge protector is recommended. The network cable entry point from outdoors into the house is the most common route for induced lightning surges. A surge protector costing a few hundred dollars can help protect the entire NVR.
