This is nothing to do with schools or anything. My dad wants to install 4 - 8 CCTV Cameras in his shop for security. I Suggested IP cameras he is keen on the idea so that is what we probably going to happen. All the cameras will be connected via Ethernet.
I am not 100% sure with them and i have a couple of questions, if anybody can answer them please do so.
1. Do the cameras need there own power supply or will they draw power from the Ethernet connection?
2. What specification of computer would i need to run 4 - 8 cameras and record them 24-7, what size of hard drives will i need?
3. Is there any software that you can run the cameras split screen and when you replay the videos you can click one particular camera it will make it full screen?
4. Do the cameras have sound?
Thanks for your help.
