AHD (Analogue High Definition) CCTV

AHD is the new standard for CCTV surveillance equipment which was released in 2015. The new AHD format allows much greater resolutions.

The cameras supplied with this kit are 720p AHD and approximately equivalent to a 1000TVL analogue camera. The upper limits of AHD have yet to be fully revealed, but for now up to 1080p is a significant improvement over the original analogue format.

Many stores use a combination of security personnel and a CCTV system to combat shoplifting. Smaller businesses, with smaller budgets for security, may have only one CCTV camera installed in a prominent place so that shoppers know they are being watched. A retailer can review the tapes on a VCR later, or observe shoppers that are behaving suspiciously and note the vulnerable areas in the store. The problem with recording and watching later is that some shoplifters will get away with stealing. On the other hand, the system still has  merit because it allows for the recognition of repeated offenders. 

CCTV technology is extremely stable and prices are very affordable. AHD seems to address the main issues that held back the other HD security camera types from taking over the analog CCTV market. Installers can use the same coax cable as traditional analog CCTV cameras and they work at the same max distance. Video baluns for AHD cameras are available for those that prefer to use UTP cable such as CAT5. Pricing on AHD cameras is only slightly more than analog.
