The LNL-500 Intelligent System Controller (ISC) by Lenel serves as the access control engine for an OnGuard system. The ISC provides power, performance, and flexibility for the most demanding applications. Multiple combinations of Input Control Modules, Output Control Modules, and Card Reader Interface Modules can be connected. The ISC can communicate upstream at 38.4 Kbps via RS-232/RS-485 multidropped configuration, modem dial-up communication, or Ethernet TCP/IP networks. The ISC can store up to 12,500 cardholders. The ISC can have two downstream 2-wire RS-485 channels or one 4-wire RS-485 channel. In either configuration, you may connect up to 32 readers or 16 devices. Each device (LNL-1100, LNL-1200, LNL-1300,LNL-1320) uses one device address.

The ICT 250 is a full-featured IP speed dome that delivers the best of both worlds: performance and affordability. This indoor speed dome provides full D1 resolution (704X480 NTSC, 704X576 PAL) with a true de-interlaced filter that produces immaculate video. Stealth Spin Technology® uses precisely machined gears, delivering unmatched smooth and accurate movement for virtually silent operation. Using state-of-the-art MPEG-4 (video) and synchronized ADPCM (audio) encoding, the ICT 250 provides superior video quality and improved network performance. The ICT 250 outperforms the competition, when compared to other network cameras using still picture encoding technology such as MJPEG or Wavelet. The ICT 250 uses ixBR® superior cross bit rate encoding technology. Using ixBR, digital video streams more fluidly because the data is encoded and streamed at a constant rate, yet it retains all the data of variable bit rate encoding! Built for maximum long-life performance, the ICT 250 deploys a high-quality slip-ring, tested for over 20 million spins!
