billbailey1971 0 Posted February 5, 2013 Kind of out of my element here, so thanks for any help. Looking to do a 24 camera system, all IP based , the longest run being close to 250 feet. Do most NVR's have POE to power the cameras or should I be powering them another way? Also I have seen on this forum something about licenses for IP cameras, is this based on the camera or the NVR?

buellwinkle 0 Posted February 5, 2013 Very few NVR's have any sort of PoE switch. With 24 cameras, you will want to have a network topography that supports that bandwidth if you are using megapixel cameras. For example, maybe three seperate managed 8 port switches with gige uplinks to a GigE switch and connect the NVR to it. NVRs are sold for a specific capacity as to how many cameras they support. For example, you may buy a 32 channel NVR to support your 24 cameras. Software is typically sold by individual license. For example, Milestone XProtect is sold by camera license, so you would buy 24 licenses to support 24 cameras. Share this post Link to post Share on other sites
skomo 0 Posted February 7, 2013 that sounds like a decent system u want... hope u got some decent coin. Things u will need to consider. Camera resolution and frame rates Total incoming bandwidth to the NVR. Storage requirements. How many days storage required? is motion only ok? A system like this you should have a recording NVR and use a separate workstation to view and play back. If it were me. I would use something similar to this Avigilon NVR, 10 TB 1x 24chn license (depending on needs either standard or enterprise) If you use all 2MP cameras then you should get approx 30 days storage based on 10ips with 50% motion. Avigilon 2 monitor workstation Linkysys/Cisco SG 300-28P network switch. (not sure if it would have enough juice to power all the cameras, its late and my head hurts to think, otherwise use a non poe switch and get a some fused AC power supply boxes with some fig 8 to the camera as well. I would even separate the networks and have the cameras coming into 1 nic on the NVR and have the workstation onto another nic. Just so you keep the incoming and outgoing bandwidth separated. just my $0.02. cheers Share this post Link to post Share on other sites
