    Hi all! New to the site. Just starting to cruise looking for what I'd like to build for my house. Are there any good brands I should be looking at?

    What I'm doing is video surveillance at my home. I did some prewiring when I built, so I have 4 outside locations with 2 x cat5e, coax, and 2/14 at each. In the garage, I just ran double cat5e. I also have 3 bundles of the same in the house, but I'd look at using those in the future, not now.

    Just so many options, and of course they all seem like good choices. I just don't work with cameras at all. Technically sound in a lot of other things though, so I don't mind reading and sorting things out if someone can save me some hassle by pointing me to the good stuff

    Not sure on budget yet, I want quality otherwise I don't see the point of it. One thing I would like is to have the camera feeds accessible to an html call or similar so that I can display them within my home automation system (using key digital). Also, I live in Canada so I'll need stupid cold weather rating ;p

    Any help would be greatly appreciated! For now, I'll keep skimming the forum

    Check out the Dahua sub-forum, esp the sticky about the Starlight models. They kick-ass in low light, and have some varifocal models which let you get the exact view you need (vs getting a fixed lens and being stuck with that non-adjustable view). Hikvision is another good brand (IMO), but they're just now starting to make cameras that match Dahuas Starlight models. No reviews on those yet.

    I've got the "New Posts" URL bookmarked and use it a few times a day. Great way to see trending threads across the entire site, which leads to learning a lot.

    Lots of info in the forum, most seems like sales rather than non-biased discussion. That's ok though, I can sort through that
    What's the better NVRs? Is that the consensus to go with or is it just better to build your own machine? I think it would be hard to beat the price of NVRs as I see them. just looking at the 8 channel Dahua Lite and Pro. Both seem like good units (spec wise anyway)

    IMO, the most popular cameras for the last few months here have been the Dahua Starlight models here:
    Dahua 2MP Starlight Lineup

    Here's a link to the review thread of the most popular Starlight, which is the varifocal turret:
    Dahua Starlight Varifocal Turret (IPC-HDW5231R-Z)

    The thread is ungodly huge, but probably worth starting on the 1st page and fly through, just looking at the pictures and videos folks have uploaded. You should get a pretty good idea if this camera would be a good fit for you. If your browser lets you hit the space bar to advance down a page, you should be able to get through a lot pretty quickly.

    Hikvision is the other manufacturer I'd feel OK with using, but they're just now starting to produce cameras that match the low-light performance of Dahua's Starlight series. So no real reviews of them yet.

    For your NVR question, there are pros and cons for both.

    To me, the biggest pro for buying a NVR that matches your cameras is that the NVR can record the extra motion detection events (like tripwire, intrusion detection, missing object, etc). If your NVR brand doesn't match a camera brand, as long as both of them support Onvif, you can record the basics, like on a schedule (24x7, 8x5, whatever you want) plus record on basic motion detection. Onvif doesn't support the extra motion detection events (tripwire, intrusion detection, etc). Personally, I get a lot of use out of intrusion detection zones, so I got a Dahua NVR to go with my Dahua cameras. I also have a single Hikvision camera. It records to the Dahua just fine, but I can't use Hikvision's extra motion detection events to kick off recordings. I still use them, I just have the camera send me an email with a photo when those rules are triggered.

    If you build your own NVR, it seems like Blue Iris is the most popular software. There's a whole forum (with subforums) on here dedicated to Blue Irish. It seems to have a whole lot more options/tweakability than regular NVRs, but it's up to you as to how deep you want to go with it. I don't have any personal experience with it, but a lot of folks here do. As of now, Blue Iris can't record the extra motion detection events from cameras (like tripwire, etc). That's what ruled it out for me.

    If you chose an off-the-shelf NVR (like the Dahua models you mentioned), do a search on here for their product numbers and see if there's any review/owners threads. I have a Dahua 5216-4KS2 and it has a few glitches that I'm really hoping a new firmware irons out.

    Welcome! I too am new here and been reading a LOT, thus I would like to share with you what I have learned here and elsewhere.

    1) Excellent job! This is the hardest part for most - installing wires in a building already built.

    2) Since you have coax and power you can even install a super cheap coax based system - from the research I have done: you will want to avoid that if you can afford to get a nicer system.
    Thus, I came here to read more about IP security cameras.

    3) DORI - Detect, Observe, Recognize, Identify ranges and resolution - to ID someone you will need something like 80-100 horizontal pixels across the suspect's face. Thus you will need to adjust the focus and placement of cameras you wish to use for ID purposes to ensure a good facial image capture. [ Edit: 8/6/2017 - 8 feet or less should be the height for installing cameras to get a good angle for a potential facial image for ID purposes ]

    @nayr posted a good chart for Dahua cameras - hint you'll want to checkout a lot of the posts from nayr as he is sharing some really good knowledge from his experiences.
    Dahua 2017 International Product Catalog (Q1)

    4) I learned that Hikvision and Dahua were some of the top OEMs for security cameras - however, as pointed out by @aristobrat Dahua is currently in the lead with their "starlight" models which work very well for nighttime images. Thus I am currently getting Dahua products.

    5) Dome cameras do not work well outside due to UV degradation of the domes, as well as glare issues external to the dome, as well as IR lights internal to the dome. Domes can be useful if it is a very dusty environment to protect the camera.

    6) Junction boxes maybe useful so that you can put the bundle of PoE wires in the box. Some people are able to put the wire bundle within the walls, or other options.
    Here is a discussion of sourcing Junction boxes... note you can sometimes modify junction boxes sold in places like home depot. [ edit 8/6/2017 - I really like junction boxes now that I have used the Dahua ones associated with the cameras I installed. Installed properly they help weather proof your install - I used silicone stretch tapes to help weather proof the PoE connection and then put the wiring pig-tail / connect into the junction box - worked very nicely. ]
    Buying Dahua Junction Boxes locally... just DON'T do it
    UPDATE: 11/30/2017
    Dahua has a new water proof junction box for the turrets, even better than the PFA137 junction box ( which while very nice was not water proof )

    accessory sheet:

    7) I was looking for a front door area camera and this model turns out to fit my requirements well for my place: Dahua IPC-HDBW4231F-AS
    Here is the discussion which lead to my decision - note Nayr does not like door bell cameras, thus I have opted not to get one and am getting this instead.
    ( I will be getting a 2.8mm lens as the suspects will be right in front of the camera, and I will be installing it in a location to minimize UV exposure. ) [ edit: 8/6/217 - the cover comes off so you can paint it to match your building ]
    Is there a good small camera for front and rear doors?
    [ update: 01/25/2017 ]
    A second camera can help increase the chances of a good ID image for those coming to the front door, this camera is placed low to look up and get that image.
    Is there a good small camera for front and rear doors?

    8) Aristobrat has already pointed out the most popular camera for this forum as well as a link to the super long discussion:
    Dahua Starlight Varifocal Turret (IPC-HDW5231R-Z)
    Dahua Starlight Varifocal Turret (IPC-HDW5231R-Z)

    Summary: Best price / night time performance currently on market, also it is varifocal ( you adjust the focus typically done only during installation to cover your view )

    9) Avoid Dahua Chinese market cameras - while very affordable - you may have issues updating the firmware, and some cameras have various services running which appear to "call home" - thus if you do get them you will have to be certain to properly secure them. [ edit - 8/6/2017 - you should expect to have daylight saving time issues with the Chinese market cameras as China does not have a day light saving time adjustment ]

    [ edit - 12/18/2017 - possible code signing by Dahua may make English language hacks unsuccessful ]

    10) NVR options:
    NVR should be picked to match the cameras you plan to purchase, as each vendor has advanced features which go beyond the ONVIF spec.
    A) NVR w/ integrated PoE ports - will be the easiest and quickest to setup ( basically plug and play if you matched the brand / vendor ). This will also typically be the most affordable for new equipment.
    B) NVR w/ separate PoE switch - allows greater flexibility and makes it easier to directly access cameras. Expect to spend more time and funds.
    C) PC running VMS ( Video Management Software ) w/ separate PoE switch. A number of power users really like the flexibility and features. If you're willing to take the time and source a good used Windows PC w/a CPU that has h.264 hardware features you can find a nice system at a decent price that can do this for you. Example: Blue Iris software is well liked - runs on a windows PC, do buy it if you plan to use it as the demo version is limited in functionality and performance. Others are picking nvrs purpose built for security cameras.​
    After reading and looking at the PCs I have available I've chosen the following Dahua NVR5216-4KS2 / NVR5216-16P-4KS2
    Dahua NVR5216-4KS2 / NVR5216-16P-4KS2
    ( if I already had a good windows machine available at home I would have tired Blue Iris )

    11) PoE power - or PoE power sourcing equipment. Reading the options here alone is enough to make your head spin.
    If you plan to have a lot of PoE cameras or PoE devices [*] it looks like one of the cost effective options maybe getting the Dahua nvr5216-16P-4KS2 ( includes 16 ports of PoE ) or a used PoE/PoE+ switch from ebay. There are advantages to having a separate switch - it allows you to more easily access each camera's interface separately using a computer on the same network.
    [ * - edit 8/6/2017 - for non-camera PoE devices you probably want to look at a good managed PoE switch so you can segment your various devices and camera ]

    12) VPNs and IP Camera / NVR security issues:
    ALL security camera companies have significant Internet Security issues - Hikvision and Dahua both have issues, here is an example for Dahua which @Zeddy posted:
    Dahua Backdoor Uncovered
    Dahua Backdoor Uncovered

    THUS we have to take some time to properly secure our security cameras - or else they will be used to attack others on the internet, and perhaps even used against us.

    Here is a good reference on VPNs thanks again to Nayr:
    VPN Primer for Noobs
    VPN Primer for Noobs

    13) IR illumination for dark - sometimes the cameras themselves do not provide enough, OR to get a better image we want to disable the camera IR to get a better picture.
    Here is an example of IR use - just checkout the first post... note this particular product link is no longer available, but you can find similar products by searching.
    IR Cannon w/Adjustable Focus
    IR Cannon w/Adjustable Focus

    There are other posts in IR lighting which are useful.

    Note: 850nm lights glow red - and give off the best results for night time / darkness view of security cameras. IR emitters in the 940nm range do not provide as much useful illumination for security cameras but are not visible to the human eye. ( Cell phone cameras maybe able to detect both )

    Also IR may attract bugs, and thus spiders may want to set a web by the IR emitter - typically the Camera

    14) Other starlight cameras to consider if you need a better longer distance view, and worth considering:

    This one will give you an even better night view.. but will cost about 2x what the Dahua Starlight Varifocal Turret (IPC-HDW5231R-Z) does.

    17) SD micro cards in cameras - some models have SD micro card slots - which can be very useful for local storage during times when there maybe issues with the NVR or network.

    35) bp2008 states:
    "Note that to capture license plates at night you need to set the shutter speed manually to a fast enough value that you get a sharp picture of a moving vehicle and do not overexpose the license plate. This will make the camera mostly useless for anything else at night, because everything else will be too dark. For this reason, starlight models aren't terribly important for license plates and you may be better off finding a 4MP or 8MP model with a similar amount of zoom."
    "Faster exposure time is the key to sharper images. Usually requires more light to keep the noise down and image quality up.
    WDR and 3D noise reduction can both introduce a little ghosting/trailing particularly on a fast-moving subject. I'd suggest keeping WDR completely off at night and reducing 3D noise reduction as far as you can stand to do."

    40) Passive PoE vs Active PoE:
    "The difference between passive and active PoE is the auto negotiation. Active devices do a handshake between the Power Supplying Equipment (PSE) and the Powered Device (PD) before it turns on the power. Passive is always on. It’s all about the right tool for the job.

    The big benefit of active is not having to think about what you plug in. We recommend active PoE PSE in cases where you might plug something non-PoE into a port by accident, like by your office desk, or the PD requires it, like Cisco WAP’s. There are active PoE injectors if that fits your application: All Products

    The benefits of passive PoE are simplicity, reliability, and affordability. In a case like PoE cameras, the passive injectors work great, and Darwin awards go to people trying to plug a laptop into the port on the ceiling and unplugging a PoE camera." - Tyler Andrew

    77) Technical reason why Reolink is disliked by Blue Iris fans:
    "When using direct to disk, blue iris can only start recording on a new iframe as explained in the help file. 99.9 percent of the cameras on the market allow this adjustment. Reolink does not. So you need to set a really long pre trigger record and hope for the best." - Fenderman

    "We, unfortunately, live in a HOA. The association informed me that my installed cameras were not approved. My response was that I didn’t see any restrictions in the controlling documents and that if they wanted me to remove my cameras that I wanted a letter from their counsel that they would compensate me and my family if a property crime or worse occurred.

    Our cameras were approved." -

    88) Adding Dahua OEM IP PoE cameras to a Lorex Dahua OEM NVR
    The multi camera view screen often will be blank for the Dahua OEM cameras on a Lorex NVR, you will need to configure the substreams so that the NVR knows what stream to display in the multi-view

    FYI, anyone searching about cameras for cold weather: I am running several Dahua Starlight Varifocal Turrets (and a Hik 4mp) and all are doing well below zero degrees Fahrenheit. We got down to -7 F last night and its been below zero for over 24 hours. No issues so far.
