Hey Guys, Sam's has got the Q-See 4 Channel HD NVR Security System w/ 2TB Hard Drive, 4 1080p IP Cameras with a $200 off coupon for $699 'til mid April I think. I know this is a pretty standard deal (Black Friday) etc... but I had a question about possible expansion for this system. I would like to eventually have 8 1080p cameras for home security use, so I initially dismissed this deal cause its only a 4 Channel NVR...but at $700 for everything its hard to pass this up right now. I've seen the promotional material from Q-See that says you can combine their systems (from different locations, etc...). My question is this: What would be the downside to buying 2 of these and combining the systems on the same home network. My plan would be one now...and another possibly next year or so. (Got write a BIG tax check this year...so Trying to keep expenses low for a little whileO Just looking for opinions from you smart guys, would also love to hear any pros/cons for this system. (I THINK this is a Dahua rebrand right?) Thanks - John

Hey Guys/Gals, New to the forum and to the whole surveillance system world as well. Looking for some advice from you smart guys… Just built a new place and had it prewired for cameras (cat5e). Initially planned on using analog cameras & a DVR, connecting via baluns to make use of the Cat5 wiring. After reading here (non-stop for the last week!!) I’ve changed my mind and now in the process of figuring out how to configure my home with IP Cameras & NVR. Here’s what I’ve come up with: Initially start out with 4 cameras to cover the entrances into the home & an NVR with room to expand down the road (probably 9 or 10 camera’s total…1 of them a PTZ eventually) The initial purchase plan: 1 - Dahua NVR3216 (non - POE, but Lots of expandability w/16 chan) 3 - Dahua HDW2100 Dome Cameras 1 - Dahua HFW2100 Bullet Camera For power I was considering this PoE injector: WS-POE-12-1U 12 port passive Power over Ethernet PoE Injector with 48v 120watt pwr supply (made by wifi-texas) I know NOTHING about PoE, the above injector comes in LOTS of different flavors (and prices!): 48v/120watt, 48v/60watt, 24v/120watt,24v/60watt Here’s my questions: What type/amount of PoE power do I need for about 10 cameras? Anybody used this type of rack mounted injector before? Would it be better to go with Dahua NVR w/built-in PoE? or maybe individual injectors using individual 12v pwr supplies? ANY advice/critiques/comments of my plan would be GREATLY appreciated. Thanks in advance! - John

Thanks for the replies guys: Rick, My problem is… I really am a dumb-ass when it comes to the Volts/Amps/Watts stuff. Here’s the specs on the cams I plan to end up with… 4x 1.3mp Bullet Cams - IPC-HFW2100, DC12V, PoE(802.3af), <6W 2x 1.3mp Dome Cams - IPC-HDW2100, DC12V, PoE (802.3af), <4W 1x 2.0mp Dome Cam - IPC-HDB3202, DC12V/AC24V, PoE(802.3af), <10W 1x Some kinda PTZ…specs approx: AC 24V/3A (±10%) / DC12V optional, 17W, 35W(IR on, Heater on) Do I add the Watts per cam and then decide on the injector required? Or is there more to it than that? The PTZ will be down the road a ways…I think that may require an additional power supply right? SectorSecurity, I plan on using an NVR connected to the internet, so I assume my wiring should look like this? Router(connected to internet)--->NVR ---->PoE Injector----->IP Cameras Does that look right? Thanks again, John
