Hikvision DS-2CD1021G0-I 2MP Eco IR Bullet IP Camera

This is a digital bullet IP camera made by Hikvision, with a focus on being economical (ECO) and suitable for outdoor use. Here’s a breakdown of its description, components, how it works, and uses:

Description:

• Bullet Camera: This refers to the camera’s cylindrical housing design, commonly used for outdoor applications due to weatherproofing.
• 2MP Resolution: Captures video with 2 megapixels, offering good image quality.
• ECO: This  indicates a series or model focused on being economical or cost-effective.
• IR Bullet: Refers to the infrared (IR) illuminators for night vision capabilities.

Components:

• Lens: (4mm  refers to the focal length) This captures light from the scene being monitored. A 4mm lens typically offers a wider field of view.
• Image Sensor: This electronic device converts light into an electrical signal. The 2MP (megapixel) indicates the resolution of the camera (number of pixels captured).
• Image Processor: This chip processes the electrical signal from the image sensor to create a digital video image.
• Infrared (IR) Illuminator LEDs: These LEDs emit infrared light invisible to the human eye but can be picked up by the camera sensor. This allows for night vision even in low-light conditions.
• Network Interface Card (NIC): This chip allows the camera to connect to a computer network and transmit video data over Ethernet cable.
• Housing: The weatherproof housing protects the camera’s internal components (bullet-shaped in this case).

How it Works:

1. Light Capture: The lens focuses light from the scene onto the image sensor.
2. Signal Conversion: The image sensor converts the light into an electrical signal.
3. Image Processing: The image processor processes the electrical signal to create a digital video image.
4. Daylight Operation: In well-lit conditions, the camera captures color images.
5. Low-Light Operation: In low-light conditions, the IR illuminator LEDs turn on and emit infrared light. The camera sensor can pick up this infrared light, allowing it to capture black and white images even in the dark.
6. Video Transmission: The camera transmits the digital video data over the network using the Ethernet connection. This data can be viewed live on a monitor or recorded for later playback.

Uses:

• Home Security: Monitoring entrances, exits, and common areas outside a residence for cost-effective security.
• Business Security: Surveillance of outdoor areas of storefronts, warehouses, or building perimeters, at an economical price point.
• General Outdoor Surveillance: Monitoring public spaces like parks or parking lots, with night vision capabilities for around-the-clock security (depending on the specific location’s regulations).
