The Swann SW242-4AI (DVR4-8500AI) is a perfect choice for residential or commercial applications looking for reliable multi-camera security management at an affordable price. Some of its more important features include H.264 level video compression technology for better file management, a network connection for remote Internet access, upgradeable HDD storage and audio I/O ports.
H.264 Compression
Video is captured using the H.264 level video compression method, also known as MPEG-4 Part 10. With its ability to generate great looking video images while keeping file sizes to a minimum, H.264 is supremely well suited as a compression medium for CCTV DVRs.
Motion Detection
An advanced motion detection function, based on area and sensitivity, can be applied to each camera input. When used to trigger recording, motion detection greatly cuts down on storage and network requirements and also makes it easy to locate event material.
Easy Storage Expansion
Storage capacity is easily expandable by adding two more drives, in addition to the 250GB HDD already installed in the DVR.
Optional Mouse Control
Users have the option of connecting a USB mouse to this DVR to navigate DVR functions.
