+### DJI O4 vs Analog Video Camera
64
+
65
+Comparing DJI O4 and analog video cameras involves several aspects. Here's a breakdown:
66
+
67
+**Summary Table**
68
+
69
+| Feature | DJI O4 (Digital) | Analog Video Camera |
70
+| ------------- | ---------------- | ------------------- |
71
+| Image Quality | **High** | Low |
72
+| Range | **Long** | Short |
73
+| Features | **Advanced** | Basic |
74
+| Complexity | High | **Low** |
75
+| Cost | High | **Low** |
76
+| Interference | **Low** | High |
77
+
78
+
79
+### Can a 2W Analog FPV Transmission System Run 24/7?
80
+
81
+**Yes, but with precautions:**
82
+
83
+#### ✅ Conditions for Safe 24/7 Operation:
84
+- **Good cooling** (heatsink + fan recommended)
85
+- **Stable power supply**
86
+- **Antenna always connected**
87
+- **High-quality VTX components**
88
+
89
+#### ⚠️ Risks:
90
+- Overheating
91
+- Component wear/failure
92
+- Possible RF interference
93
+
94
+#### 🔧 Tips:
95
+- Add active cooling
96
+- Use lower power if long range isn’t needed
97
+- Monitor temperature
98
+- Consider industrial-grade VTX or digital systems for reliability
99
+
100
+#### Issue: This device is not well-suited for continuous surveillance applications.
101
+
102
+Limitation: Requires a cool-down period after 4-5 hours of operation, suggesting potential overheating or reliability concerns with extended use.
