Which Video Doorbell Should You Choose? 2026 Hong Kong Comparison of 7 Models: Battery-Powered, No Wiring vs PoE (From HK$650)

Installing a doorbell at your front door—the most frustrating part isn't choosing a model, it'spower and signal. Most Hong Kong tenement buildings and village house corridors have no network ports, and housing estates usually don't allow drilling into exterior walls—so choosing a model is really about what conditions you have at your front door. Below are the actual prices and differences of 7 in-stock models at our store.

30-second takeaway:Renting / don't want to run cables → EZVIZ EP3x (HK$650, the most affordable dual-camera option); need a stable Wi-Fi signal → Reolink 2K Battery Doorbell; already have a network cable at the door or willing to run one → Reolink PoE 5MP (HK$778) to solve power and connectivity in one go.

Reolink 5MP PoE Camera Video Doorbell with Chime Person Detection — HK$778

The only PoE doorbell in the store. A single Cat5e／6 Ethernet cable supplies power and transmits data at the same time, so no battery or Wi-Fi is needed, and an indoor chime is included. Priced at HK$778, but only if there is already a network cable at the doorway or you’re willing to run one. If your older building has no wiring point, don’t force it.

EZVIZ EP3x Dual 智能門鈴 / 貓眼攝錄機 — HK$650

Dual-camera design: one camera faces straight ahead to capture faces, while the other points downward to view packages on the ground by the door. At HK$650, it is the cheapest option in the store, suitable for renters or anyone who doesn’t want to drill walls or run cables and simply wants to stick it on and use it.

EZVIZ HP8 5MP 智能電池視訊門鈴套裝 — HK$699

The 5MP version comes with an indoor chime, so it doesn’t rely on your phone to ring. Suitable for households whose family members aren’t used to using a phone app to answer the door.

SpotCam Ring 2 門鐘攝影機 — HK$799

A doorbell camera at a mid-range price. Suitable for users who only want it to record when someone presses the bell or walks past, without needing the full range of doorbell communication features.

EZVIZ DP2 — HK$839

A 2K wireless doorbell priced at HK$839. No wiring or electrician is needed, making it the most reliable choice for anyone who doesn’t want to deal with installation work.

Reolink 2K 4MP Dual-Band Wi-Fi Battery Video Doorbell 全無線智能門鐘攝錄機 — HK$999

2K 4MP dual-band Wi-Fi (2.4G＋5G), powered by a battery. In corridors or village houses with weak Wi-Fi, 2.4G provides better range while 5G provides faster speeds, resulting in far fewer connection problems than single-band models.

EZVIZ EP8 ULTRA 智能門鈴 /旗艦級AI 雙鏡頭智慧門鈴套裝 — HK$1,299

A flagship dual-camera AI doorbell priced at HK$1,299. It likewise offers two viewing angles—one for people and one for the ground—but with more advanced sensing and higher image quality. It is especially effective for units with narrow entrances where pedestrians pass close to the door.

4. 5 things to check before placing an order

• Is there a network cable point at the doorway?Yes → Consider PoE directly; no → Choose a battery or Wi-Fi model.
• How many Wi-Fi bars are there?Test with your phone at the doorway; if the signal is two bars or below, a single-band Wi-Fi doorbell is not recommended.
• Can it be drilled into the wall?This usually isn't allowed in a rental. Use a drill-free adhesive mount or a door-frame clamp model.
• Do I need an indoor chime?If there are elderly people or children at home, phone notifications may not be enough. Choose a bundle that includes a chime.
• Do I need to see packages on the ground?Yes → Choose a dual-camera model (EP3x／EP8 Ultra). Single-camera models usually only capture people's heads.

5. Privacy: Practical Tips for Doorway Cameras

A doorbell camera will inevitably capture part of the public corridor or neighbours coming and going. Hong Kong's Office of the Privacy Commissioner for Personal Data has consistently recommended that you “only collect what is necessary.” In practice, three steps are enough: narrow the camera angle to your own doorway and a short section in front of it, put up a small “CCTV in Operation” notice, and set a video retention period (for example, automatic overwriting after 7–14 days). These are practical recommendations, not legal advice. For buildings managed by an owners' corporation or commercial buildings, check with the management office first.

6. Frequently Asked Questions

How often do battery-powered doorbells need to be recharged or have their batteries replaced?

It depends on the number of daily triggers and the recording length. For a residential doorway with 10–20 events per day, most models can last several months. If the doorway is in a busy corridor, the battery will drain much faster; in that environment, PoE is actually the better choice.

Can I avoid the cloud and record only on the device?

Yes. Most models support local recording to a microSD card, so a cloud subscription is not necessarily required. The advantage of cloud storage is that the footage remains available even if the device is removed, whereas a local card disappears with it. To have both options, you will need an NVR or cloud backup.

Does a PoE doorbell have to use a PoE switch?

Not necessarily. You can power it directly with a PoE NVR or use a single-port PoE injector. If you are installing just one doorbell, an injector is the most economical option. If you plan to add cameras later, upgrade to a PoE switch or PoE NVR.

Will I need to restore the property after installing a doorbell in a rental?

Use a drill-free base with 3M adhesive. When you move out, simply remove it and touch up the paint. Do not use expansion bolts, or you may become responsible for the repair costs.
