libra 0 Posted May 18, 2010 I wants to install 4 ip cameras for a business under 2000 square feet. I read some articles that said Ip camera save you time for wiring because in an analog cctv, every wire from camera must run back to the dvr. So my question is if i were to use POE IP camera, I still have to run 4 cameras using cat5se wire back to the router(consider this as a DVR). Basically as far as running wires, it is the same for POE Ip cameras. Am I right? If i runs Cat5se wire and crimp rj45, will it works, instead of using the manufacturer's wire. I am planning on doing the installation next month. What should I need? I know i needs 4 ip cameras and poe switch only. Do i need nvr, and under what condition should require nvr. And last thing, does it need to be hook up in the customer pc or laptop all the time. And where is the HD located? Is it inside camera? Any help is appreciated. Sorry too many questions.

Soundy 1 Posted May 18, 2010 I wants to install 4 ip cameras for a business under 2000 squarefeet. I read some articles that said Ip camera save you time for wiring because in an analog cctv, every wire from camera must run back to the dvr. So my question is if i were to use POE IP camera, I still have to run 4 cameras using cat5se wire back to the router(consider this as a DVR). Basically as far as running wires, it is the same for POE Ip cameras. Am I right? Hmmm, not necessarily. As with any IP network, your layout can have all cameras run back to one switch, or you could, for example, have two cameras at one end of the building run into one switch there, then a single cable run to the far end of the building, where it and the other two cameras plug into another switch... really, there are as many different options for network topology as you can think of, and no one design is inherently better than another. IP *can* save time and costs because of this, but how much really depends on your needs. IP does give you a lot more flexibility, though. If i runs Cat5se wire and crimp rj45, will it works, instead of using the manufacturer's wire. Yes, provided you wire properly (using proper TIA-568A or B configuration). I am planning on doing the installation next month. What should I need? I know i needs 4 ip cameras and poe switch only. On the POE switch, the answer again is, "not necessarily". Almost all IP cameras can be externally powered with 12VDC or 24VAC power, the same as most CCTV cameras. That can mean one central power supply, or individual transformers for each camera that can be near the camera, or in a central location. Or you can use POE (Power over Ethernet), or any combination of the above. Once again, the benefit is *flexibility* and more options. Do i need nvr, and under what condition should require nvr. If you want to record the video, then you probably need some sort of Network Video Recorder (NVR). And last thing, does it need to be hook up in the customer pc or laptop all the time. No. And where is the HD located? Is it inside camera? No. Some cameras have limited internal flash memory, and some can use flash media like SD/SDHC cards, but not all of them support this. As with the other answers, there are many different options. You can use an NVR, which is essentially a PC or standalone box that receives the video information from the cameras via the network, processes the video, and stores it to HDD, and usually lets you search it and play it back. You can use a "hybrid DVR", which combines NVR functions with analog DVR functions. You can use Network Attached Storage boxes, essentially just small hard drive enclosures that plug into the network to provide storage space for anyone on the network. Some NAS boxes and some IP cameras support standards that allow the cameras to store video directly to NAS boxes; you'd then run the appropriate software on your PC or laptop to search and view the video over the network. As with the camera layouts, this too allows you some flexibility, as the NVR, DVR or NAS can be anywhere in the building where it can be plugged into the network; you CAN put all the equipment in one place and run all the cabling to back to it... but you DON'T HAVE TO.
