Explore our primary portfolio of field-proven intelligent power distribution, RF curtain automation, micro-switches, and bidirectional telemetry units manufactured in our Shenzhen cleanrooms.
Macro Industry Solutions: Transforming Visual Access Control & Edge Vision
The global smart video doorbell market has decisively pivoted from rudimentary cloud-tethered push-to-talk cameras to autonomous, edge-computed perimeter intelligence systems. As consumer and commercial procurement requirements mature, B2B stakeholders face stringent regulatory boundaries, demanding zero-latency connectivity, strict cryptographic sovereignty, and seamless cross-platform interoperability.
Perimeter Surveillance & Zero False Alerts
Traditional passive infrared (PIR) detection triggers unacceptably high false alarm frequencies due to thermal drifts, wind-borne foliage, and vehicular headlights. Our OEM video doorbell solutions integrate deep-learning Neural Processing Units (NPUs) that execute millisecond object boundary classification directly on device, distinguishing between human biometrics, parcels, and pets without outbound cloud computational penalties.
- Sub-150ms on-device wake-to-recording cycle
- 99.2% human/package boundary recognition accuracy
- Dynamic micro-PIR zone masking via mobile SDK
Private-Cloud & Decoupled Cloud Architecture
Enterprise clients and regional telecommunication service providers increasingly reject subscription lock-ins associated with closed proprietary hubs. Corunsmart delivers total firmware sovereignty, enabling turnkey deployment over private AWS/Azure clusters, sovereign regional datacenters, or on-premise Network Video Recorders (NVRs) supporting ONVIF Profile T and SIP 2.0 communication protocols.
- Decoupled WebRTC peer-to-peer audio/video streaming
- Customizable SIP trunking for property intercoms
- Full Tuya, Matter-over-Wi-Fi, or RTSP/MQTT stacks
Hybrid Power Management & Thermal Endurance
Unstable residential wiring, fluctuating 8V-24V AC mechanical transformers, and extreme ambient temperature ranges (-25°C to +55°C) cause severe operational degradation in standard consumer doorbells. Our industrial power supply engineering incorporates smart buck-boost regulators, internal bypass circuitry for digital/mechanical chimes, and cold-weather supercapacitor assist modules.
- Universal 8–24VAC & 12–30VDC hardwire compatibility
- Optional 6700mAh to 10000mAh Class-A Li-ion pack
- Autonomous self-heating thermal protection for Nordic regions

Commercial Implementations & Global Compliance Frameworks
A successful OEM video doorbell product line cannot rely on a single form-factor or generic wireless stack. Our localized hardware variants are engineered around target territory architectural conventions, privacy statutes, and electrical infrastructure.
Multi-Dwelling Units (MDU) & Commercial Real Estate
Modern apartment complexes and co-living operators demand decentralized access authorization. Our custom multi-tenant video doorbell stations incorporate directory scroll firmware, virtual PIN code generation via BLE, integrated RFID/Mifare 13.56MHz access badges, and dry-contact relay triggering for electronic strike locks and motorized gates.
North American Retrofit (US / Canada)
Fully compliant with UL 62368-1, FCC Part 15 Class B, and California SB-327 IoT security mandates. Engineered for shallow US single-gang electrical junction boxes, dual-screw terminal backplates with integrated fuse protection, and complete compatibility with legacy 16VAC/24VAC mechanical front-door chimes without hum or relay chatter.
European Union & UK (GDPR & PSTI Compliant)
Engineered to respect rigorous GDPR privacy boundaries with configurable on-device hardware privacy masking, localized encrypted edge storage (MicroSD up to 512GB / NAS via SMB/NFS), and strict compliance with the UK Product Security and Telecommunications Infrastructure (PSTI) Act 2024, CE RED, and RoHS 2.0 directives.

Yes. We deliver turnkey branded mobile apps on both iOS and Android platforms via Tuya OEM app engines or through our decoupled native WebRTC/SIP SDKs. We assist your team with Google Play Console and Apple App Store enterprise publishing, push-notification APNs / FCM credential management, and customized UX/UI interface re-skinning.
Lithium battery internal resistance spikes dramatically below 0°C, causing voltage dropouts during peak Wi-Fi transmission. We solve this by selecting low-temperature electrolyte chemistry rated down to -25°C, employing low-quiescent-current power management ICs (PMICs <15μA in sleep mode), and incorporating intelligent trickle-charging algorithms when connected to AC transformers.
Absolutely. Our firmware options support direct RTSP streaming alongside ONVIF Profile T (video streaming) and Profile M (AI metadata events). This allows enterprise system integrators, schools, and corporate campuses to ingest encrypted video streams directly into Milestone, Genetec, or local network-attached storage without ongoing cloud license fees.
We supply comprehensive test reports and Declarations of Conformity (DoC) from accredited test laboratories (SGS, TÜV, Intertek) covering CE RED, FCC Part 15B/15C, IC (Industry Canada), RoHS 2.0, REACH, UKCA, and battery transportation dossiers (UN38.3, MSDS, 1.2m drop test). Our engineering team handles sample pre-testing and lab coordination directly.
Standard private-label customizations on existing PCB platforms ship within 4 to 6 weeks following sample sign-off. Full ground-up ODM developments (custom optical paths, industrial ID tooling, bespoke firmware architecture) generally run on a 14 to 18-week timeline spanning EVT, DVT, PVT validation stages and final pilot runs.
