SunJess has been on the internet since 1996. The owners have been working on computers in Lansing, MI. since 1982.(Commodore64 days) In the early years we built and sold computers in the greater Lansing area. As most repair shops have found. building new computer systems is very time consuming and not cost effective. We still build computers for special situations and upgrade outdated and/or new computers. We do this with the CCTV systems we sell. We can sell you a complete CCTV system or upgrade the parts you have now. Contact us today for pricing.
