EZVIZ CB30 Dual 3K 180° Ultra-Wide-Angle Battery Camera｜See the Entire Corridor with One Camera｜IP65｜5200mAh

2880×1620 (3K／5MP)｜2.8mm F1.6, 180° horizontal｜15m IR＋10m full-color night vision｜5200mAh｜IP65

Product Overview

The most distinctive feature of the CB30 is its viewing angle: its 2.8mm lens delivers a **180° horizontal** and 56° vertical field of view. This lets it capture an entire corridor, a whole wall, or half a parking space in one shot, without relying on a pan-tilt mechanism to move around.

All specifications on this page were extracted field by field from the official EZVIZ CB30 Dual product page: CS-CB30-R100-1Q55W, 1/3" 5-Megapixel Progressive Scan CMOS, 2.8mm F1.6 (180° horizontal／56° vertical), up to 2880×1620, 15fps, H.265／H.264, maximum bitrate 5Mbps, 15m IR, 10m full-color night vision, 5200mAh, DC 5V／2A, maximum 10W, IP65, 89×82×42mm／234g.

Note its positioning: this is a **battery-powered camera** that runs on a 5200mAh battery, and the manufacturer does not specify support for mains power. If you need continuous 24/7 recording, choose a PoE model instead; the CB30’s value lies in “covering a wide area without running cables.”

Six Key Highlights

180° Horizontal: See an Entire Corridor in One Frame

Typical home security cameras have a horizontal field of view of around 90–110°, leaving blind spots on both sides when mounted against a wall. The CB30’s 2.8mm lens provides a 180° horizontal field of view, effectively allowing you to “see both corners of a wall while mounted against it.”

This viewing angle is ideal for Hong Kong corridors, stairway entrances, long living rooms, and parking spaces. The trade-off is that ultra-wide-angle lenses inevitably cause edge distortion — people at both sides of the image will appear stretched, so use the center of the frame as the reference for facial identification.

• 180° Horizontal／56° Vertical
• Cover Corridors and Long Spaces in One View
• Noticeable Edge Distortion

3K (2880×1620) and 5MP Sensor

The manufacturer specifies a maximum resolution of 2880×1620, or 3K, with a 1/3" 5-Megapixel sensor. The high pixel count is important because once a 180° scene is spread across the frame, each person occupies a relatively small portion of the image — at lower resolutions, faces would be completely unclear with this kind of viewing angle.

The manufacturer also specifies a maximum bitrate of 5Mbps and a minimum network requirement of 10Mbps. The 10Mbps threshold is higher than that of comparable products, which means your Wi-Fi needs to be of a certain quality; otherwise, the 3K stream may be downgraded.

• 2880×1620 Native 3K
• 1/3" 5MP Sensor
• Minimum Network Requirement: 10Mbps

15m IR＋10m Full-Color Night Vision

The manufacturer specifies an IR range of 15m and a full-color night vision distance of 10m (Color Night Vision Distance). These are two different modes: in complete darkness, IR produces black-and-white images; with some ambient light, the camera can produce color images.

Most Hong Kong corridors have lights that stay on, so the “10m full-color” specification is more practical than the IR range — seeing the color of a uniform or package label is often more useful than seeing a black-and-white silhouette.

• 15m IR
• 10m Full-Color Night Vision
• Best Performance in Lit Corridors

5200mAh and 10W Power Consumption

The manufacturer specifies 5200mAh and a maximum power consumption of 10W. Based on an estimated 20–30 events per day, typical battery life is 2–3 months; when installed in a busy corridor, battery life will be significantly shorter.

Note that 10W refers to power consumption during operation, including the IR lights and 3K encoding. If you plan to leave it unattended for long periods, consider pairing it with a solar panel (the same-brand PSP8 8W panel is compatible), or choose a model that supports wired power.

• 5200mAh
• Maximum 10W
• Long-term maintenance-free operation; solar panel recommended

IP65 and -20°C to 50°C

Officially rated IP65, with an operating temperature range of -20°C to 50°C. IP65 means protection against dust and low-pressure water jets, making it suitable for sheltered entrances and semi-outdoor corridors.

Please note that IP65 does not mean it can be submerged, and prolonged direct exposure to heavy rain is not recommended. The battery compartment and USB cover are the two most water-sensitive areas, so make sure they are firmly closed during installation.

• IP65 dustproof and water-jet resistant
• Not recommended for prolonged direct exposure to heavy rain
• Firmly close the battery compartment and USB cover

AI human/vehicle detection and two-way talk

The official specifications list AI Human Detection and Vehicle Detection, and support two-way talk. False alerts come at a high cost for battery-powered cameras, as each alert consumes power, so AI classification is not merely a convenience—it directly affects battery life.

For security, the official specifications list WPA-PSK／WPA2-PSK／WPA3-Personal, which are relatively newer encryption standards. Bluetooth is also supported, so pairing does not require button combinations.

• AI distinguishes between people and vehicles to reduce false alerts
• Supports WPA3 encryption
• More convenient Bluetooth pairing

• Corridors outside shops and back alleys

Why choose this model

• 180° horizontal view captures an entire corridor in one frame
• 3K 2880×1620 resolution keeps faces clear even with its ultra-wide angle
• 10 m full-colour night vision delivers colour images when the corridor is lit
