High-quality network cameras (IP cameras) provide superior security and operational oversight by offering advanced features like 4K resolution, AI-driven analytics, and seamless remote monitoring
Bandwidth and storage calculation (15 marks) A 4K (3840×2160) network camera records at 15 fps using H.265 with an average bitrate of 6 Mbps due to efficient encoding and scene complexity. Calculate: a) Per-hour and per-day storage (in GB). b) How many such cameras can be stored for 30 days on a 100 TB storage array? Show calculations and state any assumptions. (7 + 8 = 15 marks) network camera networkcamera extra quality
A network camera is only as good as its data stream. Use Quality of Service (QoS) settings on your switch to prioritize video traffic. For extra quality, reduce latency by keeping cable runs under 100 meters and using a dedicated VLAN for camera traffic. Show calculations and state any assumptions
Everyone looks at megapixels (MP), but goes deeper. A 4K (8MP) camera with a tiny, low-grade sensor will produce a noisy, poor-quality image, especially in low light. True quality involves a balance between resolution and sensor size (e.g., a 1/1.2" sensor for low light versus a 1/3" sensor for budget models). For extra quality, reduce latency by keeping cable
Define a network camera (IP camera). Explain how it differs from an analog CCTV camera in terms of signal transport and system architecture. (6 marks)
While a 4K (8MP) network camera offers superior detail, extra quality is achieved by properly configuring the bitrate. A high resolution with a low bitrate results in compression artifacts. For optimal results, use a variable bitrate (VBR) at the highest setting your network storage can handle.
