EZVIZ EP3x Dual-Lens Battery Doorbell Kit｜162° Top Camera for People, 1080p Bottom Camera for Packages｜Chime Included

2K 2048×1296 Top Camera (162°) ＋ 1080p Bottom Camera｜5200mAh｜180° Radar Detection｜CH1 Chime Included (Supports 512GB)

Product Overview

The EP3x is a combination of a “dual-lens doorbell ＋ indoor chime.” The 162° ultra-wide-angle top camera captures people at the door, while the 1080p bottom camera is dedicated to the ground —— whether a package is left on the floor or taken away, it will all be recorded. This is the biggest difference between it and a single-lens doorbell.

The specifications on this page were extracted field by field from the official EZVIZ EP3x product page: Model “CS-EP3x”, 1/2.8" Progressive Scan CMOS (enhanced low-light performance), 2.3mm F2.2 top lens with a 162° diagonal angle, 2.3mm F2.2 bottom lens with 1080p diagonal resolution, up to 2K 2048×1296 for the main camera, 1920×1080 for the bottom camera, fixed 15fps, H.265／H.264, infrared range up to 6 meters, 180° radar detection／up to 2.5 meters, 5200mAh, Type-C 5V, up to 3W, body size 166×50×31mm／83.6g.

Storage needs special clarification: **the microSD card is inserted into the indoor chime**, not the doorbell unit. The official specification states “Local Storage (on chime)”, and the chime supports up to 512GB. This is frequently misunderstood, so it is best to know this before placing your order.

Six Key Highlights

Dual-Lens: One Captures People, the Other Captures the Ground

Most residential doorways in Hong Kong use a “place packages against the wall” setup: couriers leave the package and press the doorbell before walking away. The horizontal field of view of a single-lens doorbell only captures the upper half of a person’s body, while packages are often outside the frame. The EP3x’s bottom camera is specifically designed to point downward and cover the ground at the doorway.

In actual use: when someone rings the doorbell, you can see both the person’s face and the ground in the App; if the package goes missing, simply review the footage to see who bent down to take it and at what time. This is the source of its “evidence-grade” footage.

• Top Camera for People, Bottom Camera for the Ground
• Packages Left on the Ground Are Captured Too
• Playback Directly Shows When the Package Was Taken

180° Radar Detection: Better Suited to Doorways Than PIR

The official specifications state a 180° radar detection angle and a maximum range of 2.5 meters, with adjustable sensitivity (high: 2.5 meters／medium: 1.8 meters／low: 1 meter). Radar is not affected by temperature, making it more suitable than PIR for Hong Kong environments where corridors remain warm even in winter, and it is also less likely to trigger falsely under direct sunlight.

The three sensitivity levels are highly practical: for a corridor right outside the door, set it to “low” to avoid receiving notifications whenever a neighbour passes by; for a front garden, set it to “high” so recording starts when someone is still farther away.

• 180° Radar, Up to 2.5 Meters
• Three Adjustable Sensitivity Levels
• Unaffected by Temperature, Fewer False Triggers

2K Top Camera and 1080p Bottom Camera

The official specifications state that the main camera supports up to 2K 2048×1296 and the bottom camera supports 1920×1080, with both fixed at 15fps. The 162° ultra-wide-angle top camera ensures the full body is captured even at close range to the door; 1080p on the bottom camera is sufficient for “reading package labels clearly.”

Note that 15fps is a fixed value, not 30fps. It is sufficient for a doorbell (people do not move at high speed when approaching the door), but it is not suitable for recording fast-moving action.

• 2048×1296 Main Camera
• 1920×1080 Bottom Camera
• Fixed 15fps

5200mAh and Type-C Power Supply

The official specifications state a 5200mAh rechargeable lithium battery, Type-C 5V charging, and maximum power consumption of 3W. 3W is a very low figure, indicating good battery life —— based on an estimated 20–30 events per day, it can generally last from several weeks to two months.

Unlike some models from the same brand, it does not support AC wiring. The EP3x mainly relies on its battery. If your doorway has existing doorbell wiring, you should still consider whether a hardwired model would be a better choice.

• 5200mAh, Only 3W Power Consumption
• Type-C 5V Charging
• Primarily powered by battery; AC wiring is not supported

Includes a CH1 indoor chime: insert the microSD card here

The package includes one CH1 indoor chime (AC 110–240V power supply, 72dB within 1 meter). It also serves as the “storage hub”: the official specifications state Local Storage (on chime), supporting microSD cards up to 512GB.

The benefit of this design is that the card is not inside the outdoor doorbell unit — even if the doorbell is removed, the recordings remain indoors. This is much safer than having the card inserted outdoors.

• Includes a CH1 indoor chime
• microSD card inserted in the chime, supporting up to 512GB
• The card stays indoors, making it safer

Tamper alarm and AI detection

The official specifications list Smart Alarm as person detection + package detection, along with an audible and visual tamper alarm (with mobile push notifications). Package detection is particularly useful for households that frequently receive online orders — the notification will directly state “Package detected.”

The tamper alarm also provides practical deterrence in public areas such as corridors and stairwell entrances: most vandalism occurs during unattended periods, and an alarm sounding immediately is often more effective than investigating afterward.

• Dual detection of people + packages
• Audible and visual tamper alarm
• Effective deterrence in corridor areas

Ideal Applications

• Village houses and walk-up apartment entrances
• Homes with elderly residents who need a physical doorbell rather than relying solely on a phone

Why Choose This Model

• Dual cameras simultaneously capture faces and packages on the ground at the entrance
• 180° radar detection with three sensitivity levels, resulting in fewer false alarms than PIR
• 5200mAh battery and only 3W power consumption for extended battery life
