I have certification in Hanwha Techwin (formely Samsung) brand. I can configure your cameras, recorder and VMS software. Just provide your teamviewer or anydesk ID. No finished work, no PAY. I can also recommend on your current CCTV system if there's lag issues or frame drop or video loss. I can assist you in isolating problems. I have also experience in other brands such as Hikvision, UNV, Panasonic, Arecont, Axis, etc. I can also prepare documentation or troubleshooting procedures for your reference. You can ask me anything about CCTV Security system. Message me anytime :) Thanks!
