dont waste time running that cable..run good quality cat5/6 and use poe..its much easier, cleaner than having a bunch of wall warts, and if you get a managed switch you can reboot a camera remotely if needed...

Take a look at ubiquiti nanostations

There are plenty of 8 port poe switches(with all ports POE) that are fanless. http://www.amazon.com/Fanless-Managed-Desktop-Switch-GS1900-8HP/dp/B00GU1KULM/ref=sr_1_2?ie=UTF8&qid=1417032570&sr=8-2&keywords=managed+poe One of the benefits of poe is that you dont need to homerun everything....This makes for VERY easy installs where in the past you had to homerun all the coax... With this managed switch you get the benefit of the full control as well... The only true benefit to using an NVR with poe is that its doesnt require any real network knowlege because you just hook the camera up and you are good to go.....

If you want a local warranty and support you can put together the system for around 2000 from either costco or LTS, as well as nellys or wrightwood...Your suggestion that the OP needs to stretch his budget by a decent amount is wrong...furthermore advising him to wire rg59 is bad practice...even if he ran analog it would be smart to use cat5/6...for future upgrades..

Z2TT, you are mistaken again..the extra run from the poe switch to the NVR is irrelevant and not counted in the total run..as long as there is an intervening poe switch it doesn't the additional run does not impede performance...The NVR;s with built in poe switches are noisy and creates issues when trying to access the camera interface itself (you will need to hook the pc up directly to the NVR to be able to reach that cameras that have ip addresses that cannot be accessed via the network, some newer hikvision nvr have a virtual server feature..but that is still not the norm)...

There are lots of systems under 1k 300-500 but they wont work with the cheap cameras..with an NVR you need to match manufacturers or you are asking for trouble...Whatever you do make sure to run cat5/6 cable now while you have the walls open...you can run cheaper cameras with a pc based nvr software like blue iris...but if i were you i would get a hikvision camera like the 2532-is (s version with audio) they have SD card slots..you dont even need an NVR if you dont need long term recording...get the 2.8mm version to cover large areas/rooms...they can be had for about 150...just get a few of those until you figure it out..it makes no sense to get an NVR and then decide on the cameras later..

You have purchased the wrong injectors...those are specific to ubiquiti...they are not true poe standard 802.3af compliant..they will not work with your cameras at all..return them asap.. If you want injectors get these injectors (select injector not splitter or kit) http://www.amazon.com/TP-LINK-TL-PoE150S-Gigabit-Injector-compliant/dp/B001PS9E5I/ref=sr_1_1?ie=UTF8&qid=1416977530&sr=8-1&keywords=poe+injector or you could just buy a poe switch, this one will power 4 cameras (the other 4 ports are not poe, just standard ports) http://www.amazon.com/TP-LINK-TL-SF1008P-100Mbps-8-Port-802-3af/dp/B003CFATT2/ref=sr_1_1?s=electronics&ie=UTF8&qid=1416977620&sr=1-1&keywords=poe+switch&pebp=1416977653577

If you are going to use a standalone NVR use a hikvision NVR...there are a bunch of models, research and compare the specs...DO NOT buy an NVR from another manufacture...it will only cause trouble.. Your other option is to use pc-nvr software...IVMS from hikvision is free. Other options include milestone, exacq and blue iris (blue iris will require a modern 4th generation i5 but preferably i7 pc for 8 cameras)...the other software can run on an i3 or less because they use in camera motion vs software motion detection)..

What pricing are you looking at for Hikvision? If you can't put a 12 camera IP system together using Hikvision products for $2K, then you're buying from the wrong people. Agreed Z2TT is quoting contactor pricing...OP has someone running the cable, and appears to be doing the install himself...you can do a cam dollar system for 1600..regardless rg59 should not be run in a new install.you can do analog over ethernet...or at least run ethernet as well, because its going to be a pain to run it later..

That is an internal problem..

I think q means to use something like this...its cleaner http://www.amazon.com/Passive-Injector-Splitter-5-5x2-1-Connector/dp/B00NRHNPUA/ref=sr_1_4?ie=UTF8&qid=1416890338&sr=8-4&keywords=passive+poe&pebp=1416890383260 make sure you get the right size.. or http://www.amazon.com/SMAKN%C2%AE-Gigabit-Passive-injector-ethernet/dp/B00LS5OCTQ/ref=sr_1_6?ie=UTF8&qid=1416890338&sr=8-6&keywords=passive+poe

As Horizon points out, if your cams are poe use that...Generally, there is a good change that your ipcameras didnt come with power supplies because they are poe cameras. What cameras did you buy?

hikvision 2032 bullet or 2332/3332 turrets... The 2032 can be had for 85 dollars on aliexpress,. The 2332 can be had for about 95 and can be had with a 2.8mm wide angle lens...and has very good ir. .dont waste you money on total junk..

You dont need a dedicated graphics card regardless of the software used...why dont you just run hikvisions free vms on the pc? There are lots of options paid options, xprotect, exaq, and a bunch of others but they wont come cheap...Blue iris is great and has tons of options but will require an i7 haswell (fourth generation for those cams and to have some headroom)...i think your first mistake was runing hikvision cams on a dahua nvr...dont mix and match regardless of what they say..if you get an NVR then get a hikvision...

You must have a weak cpu...what model are you using...The exact model not just i3 or i5 as that is meaningless without specific version..

You can try using dahuas tool and see if that works...if you are able to find the default ip address you dont need the tool at all...you can log directly into the camera by hooking your camera up to the pc (or pc to poe switch, with no router attached) and changing the ipv4 address settings..there are bunch of posts on how to do it here... As an aside, you should not be mixing and matching ip cameras from other brands with your NVR..its just asking for trouble...the feed will work but motion detection and alerts may not.

What camera did you install? if you can pull it off with one hand you did something wrong...what did you screw it into? Keep in mind that once someone gets to the camera, regardless of how strong you have it mounted they can just cover it with tape or spray...

Ispy charges a monthly fee for alerts and remote viewing...if you dont need those..then its perfect because its free otherwise its sill to keep paying them in perpetuity....It should be using more or less the same cpu power as blue iris because it does its own motion detection as well

Cat5e is sufficient but i would still go cat6, in the grand scheme of things its 100 bux to future proof and have a better quality cable. Cable problems is not something you want to hassle with and rerun.Also ensure that your cable is SOLID COPPER not copper clad aluminium (CCA).. and use solid cable not stranded.

Run cat6...you can use baluns if you later want an analog system..but its nuts to run analog cables or an analog system when you have this opportunity of open walls..run as much cable and conduit to locations where you may want a connection as possible

You can reduce cpu consumption on blue iris by selecting direct to disc mode in the record tab>file format and compression.

That is the same camera internally, but in a bullet version...it will not give you the wide angle you need as its not available in your budget range.. The 2132 dome is only two axis and cannot be wall mounted.. I would look at the hikvision 2332 turret with a 2.8mm lens http://www.hikvision.com/en/Products_show.asp?id=7872 Given your budget you might consider the hikvision DS-2CD2532-I(S) or DS-2CD2512-I(S) mini dome cameras with 2.8mm lenses...the ir is a weaker but that is not an issue at the front door...they include a built in mic (S model only) and sd card slot to record locally.

Do not wire with rg59 you will be severely limiting the systems you can use. Wire with CAT6 (solid copper not copper clad aluminium) with rg59 you will be limited to using SDI, CVI or similar technology...you want to be able to use ip cameras...Its should be a crime to wire new construction with rg59 for security camera purposes..

What cameras? how many? What kind of system? NVR, PC NVR what software? Based on your question about a "higher terabyte" system i would recommend hiring someone to help you set this up...

HD-cvi is not a good solution for a new install...OP should be going with ip.
