I need to quote a customer with cow farm(under a roof, indoors), 18 cams. They have office room where recorder will be located. Few cameras will be nearly 200m away from DVR. They have no preference - IP or HD-SDI, they simply need good quality images, 1.3mpix or 1080p.
I`m leaning towards IP system because:
1. PoE, no need for separate power cabling as for SDI cameras. Huge saving cost considering size of farm and meters of power cabling it would need.
2. I can easy extend PoE for long distance cameras with Veracity PoE extender.
3. Wide range of reasonably priced and good quality cameras.
4. I`ll be using Luxriot and will have direct support from them.
Luxriot guys will help me calculate PC/server spec I need, so that`s not an issue. I just wonder if HDD will be able to handle such amount of data recording
Because all cameras will be on motion detection, they won`t be recording at the same time, therefore bandwidth should be ok for 100mbit network, as H264 1080p cam at 12fps produces about 7mbps. But then - which CPU will be able to decode H264 for live view for 18 cameras? Huge decoding power required. Or live view will be second stream - JPEG. But what will happen to bandwidth them? Need to talk to Luxriot on this.
Looking at Arecont Vision MegaDome 2 domes or MegaView 2 all-in-one solution cameras. Need WDR, indoor & outdoor cams, with varifocal lenses.
Some areas are poorly lit, might need to use cameras with IR lighting(PoE might not be able to handle IR). Because its farm, would there will be lot of flies/bugs attracted to IR lighting coming from cameras? I`m trying to explain them - install decent lighting and we won`t need to use IR cameras or illuminators +its visible to human eye.
Guys, what do you think? Does this all sound right or have I missed something? Thanks!
