Thank you to all those who have responded with my software query http://www.dreamviews.com/tech-talk/...-software.html now I have another question. Our plant is upgrading our CCTV cameras installed into a much sophisticated ones a personnel suggested to upgrade it to IP video surveillance. I don't really have a background with security features of this type of cameras. Anyone here who have actually used this or can recommend a company that can offer this kind of installation services. Thank you all in advance.
