erickol 0 Posted March 5, 2012 Hello, I´m planning to install a CCTV system in my house to protect the house itself and the garden. At this moment our diagrams aims to the use of 28 cameras to protect the whole residence. When it comes to install that amount of cameras, several questions comes in mind, that I hope, some of you would help me to solve them. 1. What would be the best recommendation when choosing a place to install the DVR?, at the beginning I was planning to install the DVR inside a closet in the second floor of the house. The TV Monitor is required to be in first floor in the kitchen. 2. This questions is very close to the # 1 question. What would be the best option to monitor the DVR?, I was reading about the TV Modulators, but I don´t have any idea if these products are suitable for our needs. We have roadrunner Cable in all the TV´s around the house. Also a TV could be installed in the kitchen (as pointed in question # 3 ) but there wouldn´t be any control over the DVR, just monitoring. 3. What is the largest length that can be between DVR and Cameras using those cables with built-in video/power signal?, or you would recommend using RG6/power cables? is there any difference between the signal quality? 4. What do you think about using IP technology instead of Wired CCTV?, is there any other CONS other than having to install the power-source of each camera in separate places? Thanks for the help and suggestions. Share this post Link to post Share on other sites
tomcctv 190 Posted March 5, 2012 Hi .. cables i would look at cat5 for the number of cameras you are talking about. dont get IP and wireless cameras mixed up .... your talking two types of systems. what is your budget. ???? Share this post Link to post Share on other sites
erickol 0 Posted March 5, 2012 Hi .. cables i would look at cat5 for the number of cameras you are talking about. dont get IP and wireless cameras mixed up .... your talking two types of systems. what is your budget. ???? I´m not very familiar with Cat5 over CCTV but I just did some research and I see that they sell passive converters from Ethernet to BNC so I could wire the cameras with Cat5 instead of RG6. And about the technologies, I was wondering if IP could work better than CCTV, not mixing technologies, but to choose one of them. The budget is $4,500.00.

erickol 0 Posted March 5, 2012 BTW, I just figured out this converters are called "Video Baluns". Share this post Link to post Share on other sites
tomcctv 190 Posted March 5, 2012 The budget is $4,500.00 28 cameras with your budget cant be done. how big is your house ..... do you need 28 cameras ??? can you post a layout to be covered Share this post Link to post Share on other sites
erickol 0 Posted March 5, 2012 The budget is $4,500.00 28 cameras with your budget cant be done. how big is your house ..... do you need 28 cameras ??? can you post a layout to be covered Ok, I just attached the diagram in JPEG format. There will be 14 cameras outside and 13 cameras inside the house, that´s a total of 27. Since the project is personal, the budget could be raise. Reading in the forums I figured out that most of my questions can be solved with baluns, even the control remote access can be solved with a balun. Let me know what you think about the diagram.

LC475 0 Posted March 5, 2012 Many IP cameras can be powered over the ethernet connection. This is called PoE (power over Ethernet). So the "con" you named in question 4 is not necessarily true. In fact, it is more true for CCTV than IP! A CCTV camera can never be powered with just the RG6 cable, you always need an additional power source -- whether plugged in to 12V at the camera's location, or two 12V wires run along with the RG6 (Siamese cable). IP often can be powered with just ethernet. Share this post Link to post Share on other sites
tomcctv 190 Posted March 5, 2012 A CCTV camera can never be powered with just the RG6 cable, you always need an additional power source hi power over coax has been in the industry for years . not used as much now but in the late 80 early 90s. but all you need to look at is what ever exists and for the future that comes as a balun for cat5 also exists for coax. new stuff all the time ........ coax ..... 2 cameras 2 audio 2 data 2 alarm 2 power over 1 RG59.

Oh, cool! I had a feeling that someone would come and tell me I was wrong, since at least in theory power-over-coax clearly should be possible. I've never seen it, though.

Soundy 1 Posted March 6, 2012 Power-over-coax is rare... probably because there are so many different ways to achieve it, everyone who tried it did it a different way, meaning nobody's cameras were compatible with anyone else's systems (that's just a guess, BTW). The only ones I've seen with this were some Panasonic cameras, and they had to each have their own power supply unit that the coax passed through... and those units were stupid expensive. My boss and I have both taken the cameras apart and tried to figure out a way to power them externally, and neither of us could sort it out. Share this post Link to post Share on other sites
