Items to carry from China to home country

I am departing from Shenzhen to may home country this week.

Can I carry one set of CCTV Camera system( which includes 8 cameras and 1 DVR) and one set of Intruder alarm system (Which includes 6 wireless intruder sensors, one Control Panel, one battery and one outdoor Siren) in my check luggage?

Will they charge any taxes at the airport, or will they prohibit me from carrying these items.

Thanks
