What's your minimum order quantity, and can we start with a trial order?

Our standard MOQ is 500 units per model, but we offer a trial order option of just 100 units for first-time customers. This lets you evaluate product quality, test with your clients, and verify compatibility with your market's requirements before scaling up.

How do I know your products will pass certification in my country?

Our products are already certified to EN 14604, UL 217/268, AS 3786, LPCB, VdS, and many regional standards. We've achieved a 98% first-time pass rate over the past 5 years. For markets where we don't have existing certification, we provide full documentation packages and work directly with testing labs.

What kind of customization can you actually do?

We offer logo printing, custom packaging, enclosure color/material modifications, sensitivity parameter adjustments, custom firmware for IoT integration, wireless protocol additions (Zigbee, Z-Wave, LoRaWAN), and entirely new form factors. Our engineering team handles 15-20 custom projects simultaneously.

I've been burned by Chinese suppliers before. How do I know you're different?

We're the actual manufacturer, not a trading company. You can visit our Shenzhen factory anytime. We've been in business 23 years with the same ownership. We offer a 2-year warranty with advance replacement and have a 0.3% field failure rate across 2.5M+ units shipped.

What's the typical lead time from order to delivery?

Standard products in stock ship within 5-7 days. New production runs take 25-35 days. OEM orders with custom branding need 35-45 days for first shipment. We maintain buffer stock for repeat customers to ensure 7-day delivery on reorders.

Do you provide after-sales technical support?

Every customer gets a dedicated account manager and access to our technical support team. We provide comprehensive documentation in 12 languages, on-site training for larger deployments, and 24/7 WhatsApp support for urgent issues. Average response time is 4 hours.

Can you help me compete with cheap products flooding the market?

Yes, through positioning on reliability and total cost of ownership. A detector lasting 10 years with 0.3% failure rate costs less over time than cheap units needing replacement every 2 years. We help differentiate through certifications, faster response times, and longer battery life.

What payment terms do you offer?

For first orders: 30% deposit and 70% before shipment. After 2-3 orders, we offer LC at sight, 60-day payment terms, or consignment arrangements for qualified distributors.

Asset Tracking with LoRaWAN: GPS-Free Location for Industrial Applications

Beyond GPS Asset Tracking

GPS-based asset tracking has limitations:

High power consumption (short battery life)
No indoor coverage
Expensive cellular data plans
Overkill accuracy for many use cases

LoRaWAN geolocation offers an alternative that works where GPS fails.

LoRaWAN Geolocation Methods

1. RSSI-Based Location

Uses signal strength from multiple gateways
Accuracy: 50-200 meters
Works with any LoRaWAN device
No additional hardware required

2. TDoA (Time Difference of Arrival)

Measures signal timing differences
Accuracy: 20-50 meters outdoor
Requires synchronized gateways
Higher infrastructure investment

3. WiFi/BLE Sniffing

Device scans nearby WiFi or BLE beacons
Accuracy: 5-15 meters indoor
Transmits MAC addresses over LoRaWAN
Cloud-based location resolution

4. Hybrid GPS + LoRaWAN

GPS module on device
Transmits coordinates via LoRaWAN
Best of both worlds
Higher power consumption

Accuracy Comparison

Method	Outdoor	Indoor	Power	Cost
GPS + Cellular	5m	N/A	High	$$$$
GPS + LoRaWAN	5m	N/A	Medium	$$
LoRaWAN TDoA	20-50m	50-100m	Low	$$
LoRaWAN RSSI	50-200m	N/A	Very Low	$
WiFi/BLE Scan	N/A	5-15m	Low	$$

Industrial Asset Tracking Use Cases

Case Study: Construction Company

A large construction company deployed 2,000 asset trackers:

Equipment tracked:

Generators, compressors, welders
Scaffolding systems
Power tools (high-value)
Portable toilets

Results:

$340K recovered in "lost" equipment found
15% improvement in equipment utilization
Zero theft on monitored job sites (vs $200K annually previously)
Battery life: 3+ years with daily location updates
