USED CAMERAS. Cameras show signs of use and wear. Units were pulled from a working environment. Sold without surface, in-ceiling or pendant mounts. Domes have light to moderate scuffing but can be rotated to clearest surface.

The H4 SL camera line has an innovative and modular design that is easy to install. Built on the H4 platform, it
combines our patented LightCatcher and Wide Dynamic Range (WDR) technologies to provide exceptional image
quality in complex lighting.

Using HDSM SmartCodec™ and idle scene mode technologies, the H4 SL camera optimizes video streams in real time,
minimizing bandwidth and storage requirements while maintaining clear, detailed images. It integrates with Avigilon
Control Center™ video management software (VMS), and is ONVIF-compliant for integration with a third-party VMS.
With significant improvements to bandwidth savings and lower storage retention, as well as its easy-to-install, modular
design, the H4 SL camera line adds even more value than before, lowering your total cost of ownership.
