The new PTC-401C IP Network PTZ from Elmo Mfg. Corp., Plainview, N.Y., combines digital video output from a built-in Web server with MPEG-4/motion JPEG compression, and analog video output in one unit while making the digitized video available over LAN, WAN or public Ethernet connections. Excellent for surveillance, Elmo’s first day/night IP camera uses a removable IR cut filter to improve images in low light. Its audio functions also make it effective in videoconferencing systems.
