Mini AHD CCTV Camera
The mini AHD CCTV camera is an analog high definition closed-circuit television video surveillance standard that uses coax cable to transmit HD video from security cameras to DVRs. This AHD camera supports up to1080p HD video resolutions. AHD security cameras must be used with an AHD compatible DVR.
A closed-circuit television camera typically produces images or recordings for surveillance. The main purpose of a CCTV camera is to capture light and convert it into a video signal. Underpinning a CCTV camera is a CCD sensor (charge-coupled device). The CCD converts light into an electrical signal and then signal processing converts this electrical signal into a video signal that can be recorded or displayed on the screen.
AHD CCTV cameras are connected to DVRs using the same type of coaxial cable as traditional analog CCTV cameras, typically RG59 or RG6 coax cable. One of the advantages of AHD over HD-SDI cameras (another HD over coax security camera standard), is that RG59 coax cable can be run long distances without video loss.
Features/Pros
- With these cameras, you can create a modern and high-performance video surveillance system while maintaining the simplicity and reliability of traditional analog CCTV.
- AHD technology is the ideal solution for hidden surveillance because the size of the cameras can be really tiny, much smaller than IP cameras.
- These cameras come with 3 connectors: BNC for video, RCA for audio, and a 12VDC power plug. You can provide 12V power with an adapter near the camera or with a centralized power supply unit. You can transfer the video signal with coaxial cables.
