+### DJI O4 vs Analog Video Camera
14
+
15
+Comparing DJI O4 and analog video cameras involves several aspects. Here's a breakdown:
16
+
17
+**Summary Table**
18
+
19
+| Feature | DJI O4 (Digital) | Analog Video Camera |
20
+| ------------- | ---------------- | ------------------- |
21
+| Image Quality | **High** | Low |
22
+| Range | **Long** | Short |
23
+| Features | **Advanced** | Basic |
24
+| Complexity | High | **Low** |
25
+| Cost | High | **Low** |
26
+| Interference | **Low** | High |
27
+
28
+
29
+### Can a 2W Analog FPV Transmission System Run 24/7?
30
+
31
+**Yes, but with precautions:**
32
+
33
+#### ✅ Conditions for Safe 24/7 Operation:
34
+- **Good cooling** (heatsink + fan recommended)
35
+- **Stable power supply**
36
+- **Antenna always connected**
37
+- **High-quality VTX components**
38
+
39
+#### ⚠️ Risks:
40
+- Overheating
41
+- Component wear/failure
42
+- Possible RF interference
43
+
44
+#### 🔧 Tips:
45
+- Add active cooling
46
+- Use lower power if long range isn’t needed
47
+- Monitor temperature
48
+- Consider industrial-grade VTX or digital systems for reliability

+## explaination
7
+
8
+A type of radar that uses millimeter-wavelength electromagnetic waves.
9
+
10
+It’s often used in cars, smart homes, and security systems to detect movement, measure distance, and identify objects.
11
+
12
+Can detect animals and pets
13
+
14
+This means the radar is sensitive enough to pick up even small living beings like cats or dogs. So it doesn't just detect humans, but also pets.
15
+
16
+Works in vehicles even through glass
17
+
18
+This means the radar can function inside a car and still detect objects or movement outside or inside, even if there's glass (like car windows or windshields) in the way.
