Integration Workflow: Select, Prototype, Certify, Scale

A four-step engagement path designed for white-label partners who need predictable lead times and clear decision points.

01 · SELECT

Choose the Reference Design

02 · PROTOTYPE

Validate a Working Sample

Custom firmware and hardware parameters are adjusted to your specification. A working sample ships in a typical lead time of 2–3 weeks for your team to test.

2–3 weeks
03 · CERTIFY

Prepare for Launch

Validate GSM bands for your launch market and use PST documentation support to build the compliance file you need before volume production begins.

Pre-launch
04 · SCALE

Move to Mass Production

Approve the final firmware, trigger volume manufacturing, and export with standard 20-pcs-per-carton packing or your own branded carton.

Scenario to Specification: Choose the Right Build

Match the PST-H700-4G to your deployment before you order. Each scenario ties a concrete product fact to a practical buying decision.

PST-H700-4G installed home security alarm panel
Scenario 01

Multi-Story Home or Villa

150 wireless zones and a 100m open-area RF range.

Spec decision: place the panel on a central floor, then layer PIRs, door sensors, and remotes across every level.

Scenario 02

Retail Store or Office

8 wired zones plus 5 alarm call groups and 2 SMS groups.

Spec decision: keep existing wired door contacts, then add wireless PIRs when new displays or meeting rooms are added.

Scenario 03

Vacation Rental or Off-Grid Property

4G GSM variants with a 3.7V / 5000mAh backup battery.

Spec decision: choose the EU or US 4G model so the owner still receives calls and SMS if WiFi or power drops.

Scenario 04

Smart-Home Builder Rollout

Tuya Smart / Smart Life app with Alexa, Google Assistant, and OTA.

Spec decision: standardize on one panel so every property ships with remote arming, schedules, and voice control.

Scenario 05

Warehouse or Outdoor Perimeter

433MHz wireless backbone for sensor coverage over long distances.

Spec decision: add a solar-powered 433MHz outdoor PIR alarm to protect perimeters without trenching power lines.

Scenario 06

Legacy Alarm Migration

8 on-board wired zones accept conventional door and window contacts.

Spec decision: reuse the existing wired sensors to save labor, then expand with wireless detectors over time
