The **ACV-D1122-R/Q** is a high-performance **Full HD (1080p) Analog Dome Camera**, typically utilized in professional CCTV surveillance systems. It is designed to work over coaxial cabling using standard analog high-definition protocols. --- ### ## Technical Specifications & Electronic Components The device integrates several key electronic subsystems to process images and manage power: | Component Category | Specification / Part Details | | :--- | :--- | | **Image Sensor** | 1/2.7" Progressive Scan CMOS Sensor | | **Resolution** | 2.0 Megapixel (1920 x 1080) | | **Signal System** | PAL/NTSC (Switchable) | | **Video Output** | 1 x BNC (TVI/AHD/CVI/CVBS switchable) | | **Min. Illumination** | 0.01 Lux @ (F1.2, AGC ON), 0 Lux with IR | | **Power Input** | 12V DC ± 15% | | **Infrared (IR)** | Smart IR LEDs with up to 20m range | --- ### ### Key Electronic Features #### 1. Signal Processing (4-in-1 Output) The camera features a **multiprotocol bridge chip** that allows it to switch between four different video signals: * **TVI/AHD/CVI:** High-definition analog formats. * **CVBS:** Legacy standard definition analog signal for older DVRs. #### 2. Day/Night Functionality It utilizes an **ICR (IR Cut Filter Removable)** mechanism. This is an electronic-mechanical part that slides an infrared-blocking filter in front of the sensor during the day to ensure accurate color reproduction and removes it at night to allow IR light for night vision. #### 3. Smart IR Control The electronic board includes an **Adaptive Infrared Controller**. Unlike standard IRs that can "wash out" subjects close to the lens, Smart IR adjusts the intensity of the infrared LEDs based on the proximity of the object to prevent overexposure. #### 4. Power Circuitry The device includes internal **Voltage Regulators** to handle minor fluctuations in the 12V DC power supply, ensuring the sensitive CMOS sensor receives stable current. --- ### ### Wiring Configuration The electronics are interfaced via two primary connectors: ```markdown 1. DC Power Jack: Female 5.5mm x 2.1mm (Center Positive) 2. Video Connector: BNC Female (75 Ω Impedance) ```
