ভূমিকা: Why PoE?
Power over Ethernet (PoE) is the gold standard of security cameras. A single cable transmits both power and data – enabling 24/7 continuous recording without Wi-Fi issues or battery concerns.
PoE cameras are the first choice for anyone seeking absolute reliability. They are more labor-intensive to install (cable laying), but once set up, they run for years without intervention.
