Perhaps a stupid question...my apology... But if you add a PoE switch, can you use standard Cat 5E cable? Does the switch just add power over the cable run? And is there a max distance than power can be sent over the cable?

 

Also, am looking for a TP-Link 8 ports switch preferably with POE on all 8 ports? I could then start adding cameras gradually.

 

Not a stupid question at all IMHO. Yes, you can use standard Ethernet cables. Power is run over wires 7 & 8. The max distance is the same as for Ethernet cable: 328 ft. However, I would try to keep it as short as is practical, just to reduce the load on the switch/injector.

poppapete - What resolution are you running the DS-2CD2032-I at? Also I notice you purchased your cams from Aliexpress, Do you have access to the firmware updates & support? 

I use BlueIris to control the cameras. Image Format = 2048 X 1536 Frame rate 20.00 fps

I set the pre-trigger frame buffer to 60

I also use direct-to-disc encoding (no transcoding) which reduced cpu pressure by 40%

I get no support from seller at $80 a camera but firmware upgrades can be found on the web.

$80 per camera is exceptional. I may add 4-5 cameras for that price. But sounds like I'd need to dedicate a single HDD to them with direct-to-disc?

Never used aliexpress.com but the same camera is listed many times with different prices. Seemingly from different retailers. Not sure which retailer/price combo is credible. Unless there are different variations of the same DS-2CD2032-I?

I just pick the cheapest. Been using Aliexpress for a long time. Aliexpress do not pay the seller until you have received the goods in working order. The only time I was not satisfied they returned my money immediately.

 

I have 3 Cameras running on a dedicated machine with 1TB HD. I have 77GB of recordings after 5 months on this machine. C: is 86% free. The whole machine is backed up daily to my 2012R2E.  Each triggered event uses from 10,000 KB to 100,000 KB.  I live in a 4 apartment complex and each camera is triggered 3 - 5 times per day.

poppapete,

Thank you for the info. I did try 2048 X 1536 when I first got these cameras but I did not like how it seemed to cropped the image on the sides & also made the image taller. I needed the with that 1920 X 1080 gives me at the exspense of only having the camera run @2MP instead of 3MP. Also are you sure your running at 20.00 fps or was that a typo? according to the spec sheet 2048 X1536 @60Hz only supports up to 15 fps http://www.hikvision.com/UploadFile/image/2013102202280746023.pdf http://www.nellyssecurity.com/hikvision-ds-2cd2032-i.html

Not a typo but I was wrong. I have it set for 20 fpm in BI but when I checked what it was actually doing it is 14.9 fpm which as you pointed out is all it can do! My Dahua IPC-HFW4300S outdoor is running at 20  and I have an indoor Hikvision DC-2CD8153F-E which is at 25 fpm but I do not record on that one.

Jason you are going to have a hard time finding a 8 port switch that has Poe on all 8 ports without spending around 180.00. I just did a quick sirch and even a LINKSYS LGS308P Smart 8-Port Smart Gigabit PoE+ Switches is 181.00 on Newegg

http://www.newegg.com/Product/Product.aspx?Item=N82E16833124522&nm_mc=KNC-GoogleKWLess&cm_mmc=KNC-GoogleKWLess-_-IM-_-Network+Commercial+%3E+Network+-+Switches-_-N82E16833124522&gclid=CjwKEAjwucmoBRDmysGsgbDr5j0SJAAxL9abW0uzSOOvB7samUCjyNMA4Nqb0rBK9TWVc49bfhnNsRoCbYXw_wcB&gclsrc=aw.ds

 

For  that  money I would just go with what I am using http://www.amazon.com/dp/B00CXU1NHY/ref=wl_it_dp_o_pd_S_ttl?_encoding=UTF8&colid=1N6867G1O15RY&coliid=I2NLX8805SZ9S8

I'm actually thinking a device like this might be a good way to go.
WS-GPOE-12-48v120w-2.jpg
It is extra equipment, but I've noticed that the first ports to die on a switch seem to be the ones that have PoE. With something like this, you're free to use any Ethernet switch you like, with zero consideration about whether it has PoE or not.
 
The one pictured supports gigabit, has 12 ports and a 120W power brick, but they make 6, 8, & 16 port ones as well, along with 60W bricks and ones that support only 10/100 baseT.
 
More details on the one pictured can be found here: http://www.amazon.com/WS-GPOE-12-48v120w-gigabit-Ethernet-Injector-passive/dp/B00ENUHQEQ/ref=sr_1_6?s=pc&ie=UTF8&qid=1427323322&sr=1-6 or here: http://find-a-poe.com/products/

 

I'm actually thinking the 10/100 units would be plenty, even for 1920x1080x30fps, especially since the cables could plug into gigabit ports on the switch.

 

Thoughts?
