I have a Hikvision cameras system setup with 16 cameras. The cameras are now showing blurry images because they are very dirty. The cameras i have are the Hikvision DS-2CD2342WD, How do i clean these cameras and what can i use to clean them. Can they open up to clean the lenses? Regards

Good Day , I am looking for a very cost effective solution for a customer of mine. He owns a small construction company and has a yard which is 170ft by 90ft and cameras installed. Eight cameras are required but i need to get cameras that will be able to withstand the heat, dust rain etc. It can be either IP or analog. Thanks
