hello this is going to be my first ip system install and just wanted to get a second opinion before spending a ton of money. we are going to be buying around 50 cameras(42 indoor, 6 outdoor, 2 PTZ) not sure if they are the right option for me or not. the indoor cams are Sony SNC-DH110, the outdoor are Sony SNC-DH160, and the PTZs are Sony SNC-EP550, they will all be in mostly very low light. they also do not have a cover which im afraid smoke from cigarettes will ruin them. they each will be tied into a POE switch(s)then into a PC with around 24TB of HD space that will have MileStone Xprotect Enterprise for recording. im at around $33,500 and have a little wiggle room, any suggestions will greatly be appreciated, thank you for your time!
