i3's HD-over-Coax Am73 camera is designed to use existing coaxial cable infrastructure, while providing exceptional HD wide-angle image, comparable to megapixel IP cameras. The Am73 offers best-in-class video quality in 5MP resolution and is equipped with infrared imaging for both indoor and outdoor surveillance. Note: To use with the legacy HR16 encoder, set the resolution to 2MP using HD-TVI hand-held service monitor. You can request Am73 be shipped with 2MP resolution when ordering. The exterior is vandal-proof, dust-resistant, and waterproof. It is suitable for pendant, wall and surface mounting, and is compatible with our DB60 gooseneck mount. The Am73 comes with the same backbox used with our Am52RM model, facilitating easy swap-out and/or installation. It supports 3 main HD analog formats: HD-AHD, HD-CVI, HD-TVI. With a varifocal 2.7-13.5mm lens, this resilient camera is ideal for a wide range of video surveillance scenarios, such as monitoring parking lots, schools, garages, construction sites, and retail small business stores among others.
