EP3x Pro

Manufacturer reference

Manufacturer details describe the cited version. Confirm the exact unit and intended system.

Identity, imaging and selection

Device class

Dual lens battery video doorbell

Manufacturer configuration

CS-EP3x Pro is the printed configuration. Confirm the actual supplied kit and region; the navigation wording does not establish equivalence with another Kit SKU.

Image sensor

1/2.8-inch progressive-scan CMOS, with low-light sensitivity described in the cited camera section.

Upper camera lens

2.3 mm at F2.2, with a 162° diagonal viewing angle. This is separate from the downward-facing camera.

Bottom camera lens

2.3 mm at F2.2, with a 155° diagonal viewing angle. Do not add the two viewing angles into a single coverage figure.

Separate camera resolutions

Main camera: 2048 × 1296 (2K). Bottom camera: 1920 × 1080 (1080p). These are separate streams, not a combined megapixel rating.

Frame rate

15 fps fixed frame rate in the table. This is not the adaptive-rate wording used by other EZVIZ models.

Video processing

H.265 / H.264 and 2D / 3D DNR are listed.

Infrared reference

ICR infrared filtering, with up to 6 m listed for night vision. This is distinct from the PIR sensing distance and is not an identification guarantee.

Colour night-vision condition

With Color Night Vision enabled, the manufacturer reports colour viewing within 1 m in standard lab conditions using the built-in LED. Confirm the actual scene; this is not a 6 m colour-range promise.

Controls and compatibility

PIR sensing angle

120° for the PIR sensor. This is separate from either camera viewing angle.

PIR distance settings

Maximum 5 m; sensitivity settings are listed as high 5 m, medium 4 m and low up to 3 m. Confirm actual mounting, scene and settings.

Detection references

AI-powered human shape detection and package detection are listed. Actual alerts depend on setup and scene; confirm sensitivity and the intended use.

Two way talk

Two way talk is listed. Confirm the supported app, account, network and actual firmware.

Audio components

A built-in microphone and speaker are listed for the doorbell.

Tamper alert

A sound-and-light anti-dismantling alarm and EZVIZ app alerts are listed. Confirm configured behaviour; this is not a monitored response service.

Buttons

Doorbell and reset controls are listed. Confirm the actual local chime arrangement separately.

Optional CH1 chime

EZVIZ CH1 is not included in the described kit. Verify exact product compatibility before purchasing a separate chime.

Storage and network

Built-in local storage

32 GB eMMC storage is built in. Recording history depends on activity and settings; a removable microSD slot is not established by this row.

Optional cloud storage

EZVIZ CloudPlay is optional and available only in certain markets. Confirm account, current service and subscription terms.

Wireless standard

IEEE 802.11b/g/n is listed for the doorbell.

Wireless band

2.4–2.4835 GHz with 20 MHz channel bandwidth. A 5 GHz radio is not established by this source.

Protocol reference

EZVIZ Cloud proprietary protocol is listed. Confirm other devices and software by exact version.

Power, body and environment

Battery reference

5200 mAh rechargeable lithium battery in the doorbell. This is capacity, not a guaranteed service interval.

Charging and supply references

The table lists 8–24 V AC, Type-C 5 V DC ±10%, and an EZVIZ solar panel. These are separate supply references, not instructions to connect them together. Confirm the exact manual, existing chime and supplied package.

Doorbell power consumption

Up to 3 W in the cited table.

Doorbell operating conditions

-20 to 50 °C, humidity 95% or less, non-condensing.

Doorbell protection

IP65 is listed for the doorbell. Confirm seals, connections and mounting conditions.

Doorbell dimensions

166 × 50 × 31 mm in the source order. Allow separate bracket and cable clearance.

Doorbell net weight

276 g for the doorbell, distinct from the complete packed weight.

Solar panel power reference

1.2 W maximum power is listed for the solar panel. Actual charging depends on exposure and use.

Solar panel environment

-20 to 50 °C and IP65 for the panel.

Solar panel dimensions

126 × 56 × 44 mm. These are panel dimensions, not doorbell dimensions.

Supplementary solar charging

The solar panel supplements the doorbell battery; it is not the primary or only power option. Sunlight, orientation and obstructions affect charging.

Manufacturer package reference

Packed weight

650 g with package, separate from the 276 g doorbell.

Manufacturer package reference

The page lists EP3x Pro doorbell, mounting and inclined brackets, templates, solar panel, power cable, pin, three screw kits, two U-shaped wires, two wire connectors, regulatory information and guide. Confirm the actual local kit; CH1 is separately excluded.

Selection notes

• These EP3x Pro references apply only to the printed manufacturer configurations in the cited HTML edition: CS-EP3x Pro. Confirm the actual supplied ordering code, lens, region, hardware and firmware separately. These references do not declare other variants equivalent.
• Storage options and capacities apply only where explicitly listed for the exact configuration and firmware. Removable cards are not promised as included; CloudPlay is an optional regional service, not a confirmed local subscription.
• Keep upper and bottom camera views, PIR sensing and night illumination separate. Colour night vision requires its enabled mode and is described only at the stated close distance. Detection does not guarantee identity or theft prevention.
• Built-in eMMC is not a removable microSD card. No recording duration, included CH1, uninterrupted solar operation or compatibility with every old chime is promised.
• Assistant integrations are region-, device- and feature-dependent; confirm current compatibility rather than treating a logo as universal operation.
• The source configurations are manufacturer references, not confirmation of the actual ISD order, firmware, local supply or compatibility. Keep the complete model and quantity in your enquiry.
• Camera or doorphone functions require appropriate equipment, setup and commissioning. ISD provides product supply only, not an installation or monitored-response service.
• CloudPlay and remote app functions depend on the supported region, account, network and service terms. No subscription, available local service, direct emergency response or ISD OS integration is included by this reference.
• Confirm stock, price, delivery, package contents and local warranty separately. A manufacturer accessory list does not change the product quantity you enter.
