שאלות נפוצות

Q1: האם אתה מציע 256×192 מצלמת הדמיה תרמית עם עדשת 2 מ"מ?

A1: לא. למה אתה צריך עדשה כל כך קטנה? המרחק קצר ושדה הראייה גדול. האם הוא משמש בארון חלוקת החשמל? איפה אתה משתמש בזה?

Here are some possible reasons why customers choose 4mm lens FPV Drone Thermal Imaging Camera 256×192 lens

ש: On an fpv drone. Most fpv cameras have around 2mm lens.

א: The engineer said it was unrealistic. The resolution of thermal imaging is very low, רק 256*192. If the field of view is 2mm, it will be 110°, which is not far enough.

 

1. שדה ראיה רחב (FOV) & זיהוי טווח קרוב

• Broad Coverage: A 4mm lens typically offers a wider FOV (לְמָשָׁל, 45°×33°), enabling rapid detection of large heat areas. This is critical for applications like drone racing, close-range inspections (לְמָשָׁל, קווי חשמל), or search-and-rescue missions, where narrow FOVs risk blind spots during high-speed maneuvers.

• High Precision at Short Distances: The shorter focal length (4מ"מ) delivers sharper thermal details at close ranges (לְמָשָׁל, <10 מטר), ideal for agricultural monitoring (בריאות היבול) or building thermal leak detection.

2. קל & עיצוב קומפקטי

• 4mm lens cameras are often smaller and lighter (לְמָשָׁל, ≤20g), making them ideal for integration into compact FPV drones. This minimizes weight impact on flight time and agility, as seen in Axisflying and BOSCAM’s thermal camera designs for racing drones.

3. ביצועים בסביבה עם אור נמוך/עשן

• רגישות גבוהה: Some 4mm lens thermal cameras achieve <35mK NETD (הפרש טמפרטורה שווה ערך לרעש), enhancing detection accuracy in darkness, עֲרָפֶל, or smoke (לְמָשָׁל, firefighting or night operations).

• הנמוך Latency: With response times <10גברת, these cameras ensure real-time thermal data transmission during high-speed flights, avoiding lag-induced piloting errors.

4. יישומים ספציפיים לתרחיש

• FPV Racing/Drone Sports: A wide FOV helps pilots quickly locate heat signatures (לְמָשָׁל, rival drones or thermal markers) while navigating obstacles at high speeds.

• בדיקות תעשייתיות: For power grids or pipelines, the 4mm lens’s broad coverage reduces the need for frequent drone repositioning, boosting efficiency.

5. עלות-יעילות & תְאִימוּת

• CVBS Analog Output: Most 4mm thermal cameras support CVBS interfaces, ensuring plug-and-play compatibility with mainstream FPV video transmission systems.

• Bulk Pricing: Tiered pricing (לְמָשָׁל, ≥500 units at $150/unit) suits large-scale deployments in agriculture or security, lowering per-unit costs.

תַקצִיר

Clients prioritize 4mm lenses to balance FOV, מִשׁקָל, and scenario adaptability. לדוגמה:

• BOSCAM’s JS-MINI256-9 (4עדשת MM, 45° FOV) excels in drone racing.

• Wanling’s JS256 module (NETD <35mK) meets nighttime mission demands.

This configuration offers a cost-efficient, agile solution for users requiring real-time thermal imaging in dynamic environments (לְמָשָׁל, מלחמת אש, חַקלָאוּת, or competitive FPV). The 4mm lens strikes an optimal trade-off between coverage, הִטַלטְלוּת, and performance.
