Unless you are running an antiquated 10/100 network then there is no bandwidth concern for 12 cameras.

ip is hardwired as well...if you are asking this question you need to do more research. You will be better off with the turret version 2332. Hikvision also has 2mp WD cameras and 4mp WD cameras that have improved night vision over the 3mp... How do you intend to record the cameras?

Who said anything about no recorders. The NVR is on the network. That is the beauty of networking and ip. You CAN also have cameras without using an NVR, but using an SD card in the camera. This can also be used as a backup to an NVR. Yeah I read about that having a somewhat decentralized set up. Could you daisy chain cameras and then an NVR? What do you mean by daisy chain? cameras only have a single ethernet connection...you need to run an independent line from each camera. vivotek allows daisy chaining on some of their models but you pay though the roof...there is no reason to daisy chain in a small installation.

That thread is old and does not discuss turrets in detail. Turrets are better than bullets, particularly outdoors where someone can easily knock a bullet out of position. The hikvision turrets have better IR than the bullerts. Turret style cameras also are MUCH less susceptible to spider web reflection at night. But a fact you have to admit is that bullets are usually easier to mount and install than turrets, especially outside such as a brick wall or a exterior with siding, as they are point-and-shoot. Attach them to the wall and they are good to go. Turret cameras are more likely to require dismounting to adjust the direction. Nope, You do NOT have to dismount a turret to adjust it, just loosen the little screw that holds it tight. Regardless, even if you had to, its a one time event. There is no reason to use the basic bullet. It provides no useful benefit. Now, there are some bullets with features and IR options not available on some turrets, but that's a different issue.

It works the SAME exact way any computer network works...

This from the guy who promotes D1 china junk. Sunnykim failed again to read my post in its entirety.

Why? Why is it better than dome? read the threads

go with turrets.

Then he doesnt know what hes talking about. If he homeruns the cable to the NVR, the only time it uses the network (other than the one created by the nvr) is when you are remote viewing. The bandwidth used for remote viewing with be EXACTLY the same for ip or tvi, 720p or 4mp, you can set the remote viewing bandwidth cap and resolution in the NVR. Well I could never understand why this would be an issue. Since IP or TVI both have recorders connected only to the cameras. No with IP, you CAN have the cameras on the local network. They do not have to be directly connected to the NVR. This allows you to install cameras easily in a location where there is an existing network infrastructure.

Turret styles where the IR led is separated from the lens gives you the best of both worlds. http://overseas.hikvision.com/en/Products_accessries_159_i5636.html So is there any specific situation where turret, dome or bullet styles would be preferred over the other? Yes. there are a bunch of threads that discuss this.

Again that is meaningless. Is he saying you NVR cant handle the data from the cameras? or the network cannot handle it? Many folks misunderstand IP and think that it affects the network bandwidth when this is not the case if the cable is home run to the NVR or if the switch is connected to the NVR..

If its fake its a non issue...the problem is the fake camera wont help deter the criminal activity...Get a real camera.

The installer does not know what he is talking about...there is no issue..he is either trying to use a cheap NVR that has limited bandwidth and is is lowering the camera bitrate (the resolution settings is irrelevant) OR doesnt know what he is doing...there is no reason a 16ch NVR cant handle 12 cameras at 1080p I've seen this bandwidth thing being mention on this forum, but I find the explanation a bit lacking in detail as to why it is a nonissue. You need to explain what you mean by bandwidth and what you mean by issue? Lets flip it around. Why should it be an issue? and how does reducing the resolution have any effect on the issue. Any half decent 16ch NVR has enough bandwidth to hand 12 cameras at 4096kbps..bit rate is the relevant factor NOT resolution.

Cameras can be either set to 30FPS or 60 FPS, whatever max number, but the NVRs, in order to cover multi channels, have to be FPS limited Hardwarewise / or Softwarewise, a must limiting factor. Zoom in advantage? How good they could marginally be better, in spite of losing FPS. Mostly monitors would be limited to 1080P resolution, for a while. You better place cameras of good quality lens, at choke points. The Higher FPS or Higher Clock Rate or Higher Processing leads to More Electrical Heating. Less Number Of Frames could need more compressional bits for its motion compensation, leading to loss of compression efficiency. Ask the specialist near you for more details in English. Software CPU means for PC Based NVR. All of These cannot be done without burning electrical power (Watts). As to Lie 3, so claimed, please Google OV16850 from omnivision, you would find the very same sensor are used for 720P cameras and for 16MP -Full UHD 60FPS cameras. I explained this fact almost 10 times already. Your youtube things, bra-brahs, are not convincing at all. If True, there would be not many TV makers, each claiming the best video quality among all other makers. Whys? There are no ojective criterion for video quality. Sorry any one of your claims can not be based on. You may ask for more knowledges from other specialists near you. They would help you to understand CCTV systems, Goods or Uglies or Bads. NVR's are NOT limited to fps. No idea where you are getting this from. The limit is BITRATE. If you dont understand that being able to zoom in on an image or capture MORE area (for example the 3mp hik does not have more pixel per inch that a 1080p hik, BUT has more vertical field of view) is valuable then this discussion is over. The 4mp hikvision DOES have a noticeable increase in pixel density compared to the 2mp. Who said anything about software based vms? In the US we has intel haswell and now skylake processors that are VERY efficient. We can run many cameras on cheap efficient systems. Ok so you want us to ignore what we SEE with our own eyes when we compare 720p video to 1080p AND to ignore the youtube video. HOW DUMB do you think Americans are? You can no longer scam us all the way from China. It is evident from your statements that you know nothing about surveillance cameras. You can attack me in every thread, I will post OBJECTIVE evidence via youtube then let the OP decide whether to trust a china scammer or the hundreds of youtube videos available. Hmmmmm

These cameras have it corrected lenses.. That is not the issue. Op post an image... It is likely ir reflection or you need to increase noise reduction and disable wdr at night As to poor night performance, letting alone IR, that's one of the points CMOS image sensor has been improving on. Still a lot to go. As to CMOS sensors, Low light (Night) may cause video quality more affected by the inherent electrical noise level. Therefore, Noise Reduction is needed. But Increasing Noise Reduction may cause a video a bit more blurred. Turning on WDR may intensify noise level. Turn off WDR at night. Yes, you need to tune those parameters. This is false. Many CMOS sensors have excellent night vision. Really no idea where you come up with this nonsense.

Nope. 30fps is a complete waste. However, your statement that 30fps is not possible is a complete lie. Hikvision and dahua cameras easily do 30fps at 1080p no one is "forced to go for lower fps" (lie 1). Again you make to benefit from a camera higher than 1080p you need a better monitor. That is not true. The benefit is that you can ZOOM in after the fact. (lie 2). The sensors are not the same. Youtube does not lie. (lie 3) What is the heat issue in the camera? What all cameras get warm even 720p. (lie 4). Hard drive space does NOT depend on resolution but rather bitrate. (lie 5). What is a software cpu? (lie 6). What is a "power dissipations"? (lie7) So here we have 7 lies by sunnkim.

Its not sad, ip cameras have many advantages. Can you add a second hidden DVR to a TVI system? NOPE. Can you use switches with TVO so you dont need to homerun all cable which can be labor intensive. NOPE. Can you buy a TVI system with SD cards in the camera as backup. NOPE. Can you run poe and not have to mess with power supplies. NOPE. Can you easily swap to a new VMS? NOPE. Can you get more than 1080p with TVI. NOPE. What is sad is someone like you pushing D1 low res junk all the way from china. At least here you are recommending HD, a big gold star for you. Costco has 12 camera ip systems for as little as 1700. The 400 dollar systems are only 8 channel. If you want a decent quality 16ch tvi system you are paying 1000. So the difference is 700. That is nothing here in the US. We are not a third world country like most of china. We are willing to pay a bit more for a much better system. Please make sure to read the op. He needs at least 12 channels. I dont think you understand how spot monitoring works and why in the world you would need 1080p for each channel spot motoring "for certain managers". Sunnykim hopefully you will learn more about security cameras, particularly ip cameras which are new to you by reading my posts as its obvious your are a novice. A big clue to your ineptness is your need for 30fps, that is insane, its a laundromat not a casino. Learn a little before giving bad advice.

I don't have a budget, but I am willing to pay for the right camera. Which one do you have because I'd like to watch on my iphone and computer while I am working. Do you have any recommendations? As long as I catch this irresponsible person and his or her dog I will be satisfied. I need one that can identify them in the act so that I can send footage to my local PD and at least have them cited for breaking city ordinance. Hopefully vandalism if it eventually gets that far. I've experience with one security camera product, called Floureon.It is a 4CH 960H Onvif CCTV DVR with 4 x 900TVL night vision bullet cameras.1. Due to night vision,it has good quality image at night .2.Connecting to the internet and smartphone easily,you can watch image on your iphone and computer.3. it's budget under $200(Though I wanted to buy device under $100 before) .but it meets my requirements and a month passed ,still works well for me . Most of our neighbors appreciate us having the cameras and several have come over to see if we caught on camera who egged their house or other suspicious activity. 960h is junk and is half the resolution of 720p, and a quarter of 1080p. It should NEVER be installed in 2015. Ever.

720p is so cheap, 960h makes no sense. That's where I get it.. Seems like you fell for some marketing gimmick with respect to 960h being 720p equivalent..
