I'm a newbie to CCTV. I just found this forum and hope someone can help me. I am an American living in Central America and the people here doing video security systems in this country are not very technically oriented when it comes to network camera installations. I am new at this and I am doing a network video security installation on a large reptile farm that I own here . The site is 17 acres and is about 1000 meters long. I am going to install 15 low end outdoor PTZ cameras and 2 or 3 higher end PTZ cameras using the Milestone XProtect Professional video system. I have already bought one Sony SNC-RZ30 with a videolarm dome housing that I am going to install to see how good it is. I still am trying to decide on either the Toshiba IKWB15A JPEG or the Panasonic Bbhcm531a Mpeg-4 Cameras for the low end cameras. Any input on which camera to use would also be helpful. It has to be an outside network camera with Pan and Tilt. My main problem is this - If Cat5e or Cat6 has a max distance of 100 meters can I install 10 switches 100 meters (each one feeding the next) apart to cover the entire 1000 meter length of the property? This would work out good for me because I need to connect network cameras about every 100 meters. I am open to suggestions if someone could suggest a better way to connect the cameras to my 1000 meter path like fiber, DSL, etc. I was also looking at the Highwire Connect for Ethernet over Coax system but it would get very expensive with 10 (20 pair of Highwire plus 10 switches) conecting stations. I was also thinking to use 10/100Mbps/1000Mbps switchs and use them in the 100Mbps mode. Not sure if this is a good idea but someone told me that I would better results using 1000Mbps switches at long distances in the 100Mbps mode. 1. Can I use 10 swithces each one feeding the next at 100 meters? 2. Will I get better performance using the 1000mbps at 100mbps? 3. Should I use Cat5e or Cat6 direct burial cable? 4. I cannot find anywhere in the specs of the Toshiba IKWB15A JPEG or the Panasonic Bbhcm531a cameras that tells me if the cameras are IR sensitive. Does anyone know if I can use IR illuminators with either if these two cameras and which of these two outside cameras is the better choice? 5. Any suggestions on an outside dome camera with PTZ for my higher end network cameras with at least 25X optical zoom? Thanks in advance for any help.
