Cams 620 Device Connector SDK

Talk to biometric attendance terminals directly from your code. The Cams 620 Device Connector SDK gives C++ developers a clean, documented API to authenticate, query device capabilities, manage users and fingerprint or face templates, and pull attendance logs over TCP.

Overview

A C++ SDK that connects to Cams 620-class attendance and biometric devices over TCP to manage users, templates, and attendance logs.

A C++ device-communication SDK that establishes an authenticated TCP session with Cams 620-class attendance and biometric terminals and exposes a rich, header-documented API. It covers connection and serial-number verification, device control (enable/disable, refresh, restart, power off, clear admin), exhaustive parameter queries (firmware, platform, network, supported modalities, algorithm versions, capacities), user and template add/get/delete, and attendance-log retrieval by new-only, time range, since-timestamp, or full pull, with explicit acknowledgement to advance the device read flag. Results return through a typed result enum with granular status codes.

Capabilities

What it does

Connect & Authenticate

Open a TCP session, validate the serial number and credentials, and manage the connection lifecycle.

Query Device

Read firmware, platform, network, capacities, and supported biometric modalities from the terminal.

Manage Users & Templates

Add, fetch, and delete users plus fingerprint and face templates by id.

Pull Attendance

Retrieve attendance logs new-only, by range, since a time, or in full, then acknowledge the read.

Control Device

Enable or disable, refresh, restart, power off, set time, and clear admin remotely.

Features

Everything included

Authenticated TCP connect with serial-number verification using a per-device connection string and comm key
Typed result codes covering connection, authorization, data, and user-management error classes
Device control: enable or disable modules, refresh, restart, switch off, clear admin privileges
Comprehensive device parameter queries: firmware, platform, OS, network, capacities, and supported biometric types (fingerprint, face, voice, iris, retina, palmprint, finger and palm vein)
User management: add user, add fingerprint template by id, get all users, delete users and templates
Template access: bulk fingerprint templates, face template by user id, users-with-templates in one call
Attendance log retrieval: new-only, by time range, since a timestamp, or all, with read-flag acknowledgement
Time management: get and set device time; device name and OEM vendor get and set
Capability-aware design so callers can branch on what each terminal supports

FAQ

Common questions

What does the SDK communicate with?

It connects over TCP to Cams 620-class attendance and biometric terminals, authenticating with the device serial number and comm key before issuing commands.

Can I retrieve only new attendance records?

Yes. The SDK supports new-only retrieval, by time range, since a timestamp, and full pulls; after reading new logs you send an acknowledgement to advance the device's last-read flag.

Which biometric modalities can it report?

It queries the device's capability mask, reporting support for fingerprint, face, voice, iris, retina, palmprint, finger vein, and palm vein.
