Lots of factors go into reading a plate. Its never as easy to get a plate number as most people think. Angle of camera to car, speed of car, lighting, shadows, etc all play a role. If you have a precise area where plates pass through, say a driveway, you can zoom the camera's field of view in (assuming your camera has zoom option). If nightime plate reading is what you want, you need to get a special License plate camera. 4k cameras are starting to hit the market, will be interesting to see how well they do plates. Daytime should do quite well.

about 300' is usually considered the max for POE. Personally I like IP systems over coaxial. There are all kinds of ways to deal with really long runs, but since you're right at the limit, Id just try the cat6. If you have problems you can add a POE ethernet extender somewhere along the run (assuming thats possible).

Seems like a pretty nice system. Ive never used Lorex so I cant speak to that specific brand, but all the specs on this system are very good. Reviews for it are mostly good.

its always best to have as few transitions as possible. So yes one cable is more reliable than 2. Thats not to say 2 cables wouldnt work just fine. Its just one more spot for something to go wrong.

Pretty much any modern camera can do all these things. Really the only tricky/expensive feature you want is a digital pan/tilt/zoom camera.

yes you can connect both POE switches to the NVR, so long as the NVR has 2 ethernet ports available. Most NVRs have 2 ports, one for incoming cameras, and 1 to connect NVR to network. Sounds like you have no interest connecting to the network, so you should be able to use the 2 ports for the switches.

I think you bought an old analogue system to replace your old analogue system. You will need AHD or TVI DVR and corresponding cameras to upgrade to high definition.

You do not need any special type of video card. Any new-ish onboard video will do fine. i3 cpu should be fine (you arent going to have a ton of cameras) but getting i5 wont hurt. Depending on what brand of camera you go with, some cameras come with their own software. For example, I use Geovision cameras and software is included. Hard drive space is so cheap these days. I like the 4TB western digital purple drives.

cameras do not require electrical boxes. All you need to do is run ethernet cable from location of camera(s) to the room where your NVR will be located.

I dont know the answer but if you google your question you get all kinds of possible answers.

A couple of thoughts: try to do all wired cameras. If you can go through the pain of getting power to a camera, you can get ethernet cable to it and use POE (power over ethernet). Why the need to record 24/7 on certain cameras? That eats up tons of hard drive space and you are trying to keep cost down. And then when you are researching an event, it takes forever to sift through 24/7 recordings. If there is no motion occuring, why record? Personally I prefer to use a PC as the NVR because it becomes a multi use device. It can be your personal computer. You can have as many cameras as you want (or your software can support). having alerts on outside cameras can be tricky. Outside cameras can be triggered by so many things: leaves, wind blowing, trees, bushes, shadows, animals, changes in light, etc. You will be getting texts/emails all day and night. Im not sure about viewing on three TVs unless all those TVs have a PC attached to them. Maybe someone else can guide you better there. Some better cameras come with video feed outputs so Im sure if you put enough thought (and money) into it, you could run a live feed directly from cameras to TVs. HD and smartphone access is pretty basic these days. no big deal to find those.

I suppose the two terms can be used interchangably but I think of a DVR (digital video recorder) as an analogue system using a capture card and coaxial cable and an NVR (network video recorder) as using IP cameras on a network and ethernet cable.

That hard drive would do fine. Also look at Western Digital Purple drives, they are designed for cctv systems. Not sure how many cameras you have or how many hours they record, but 1TB is not much these days.

To clarify, you mention DVR numerous times but are running ethernet cables. Ethernet cables typically connect to an NVR. DVRs use coaxial cable to connect to cameras. You can buy NVRs with built in POE or use a POE switch. As far as closing in the walls, all you need for now is to have the cat6 run from each camera location to room where NVR will be located. You can decide on a brand of camera and NVR later. Your guy is right about 5th camera, as long as its on your network, its no big deal. I suggest you go with an 8 port option because you never know when you'll want to add another camera.

Im not clear on exactly what he is wanting to do, but wouldnt a POE switch connected to a wireless router work? That wireless router would then be set up in repeater mode? Not sure how well cameras streaming over wireless would do. I always prefer wired. Its always worth it to run cat5 from point to point.

silica gel pacel is to absorb moisture inside camera.

are the cameras you currently use wireless? and do they talk directly to the monitor? Might help if you mentioned exactly what you currently have.

Im imagining a standard size room with 20 desks. I would put camera back corner from door. Hang from ceiling, the more height you get, the easier see everything.

Looks like you've done your research and pretty well know how to approach it. There is no magical answer to determining where to put what cameras, just trial and error. The 2mm will have a wider field of view, 4mm will be more narrow but more detailed. Variable lens are nice because you can get the exact view you want, they just tend to cost more.

Only IP cameras are capable of POE (power over ethernet) 2.1MP is not as common IP camera, but not impossible. Typically IP cameras are 1.3MP, 2MP, 3MP, 4MP, 5MP. The larger the MP does not mean its more detailed. It means it captures more area. So if you got a 1.3MP camera and a 3MP camera, the 3 would not show a face better unless you zoomed in on a certain area. The 3 shows more area. here is an example https://www.eclipsesurveillance.com/assets/images/AHD%20KIT%20PAGE/HD%20Megapixel.png

a few questions 1.) Why do you want to record continiously? This makes researching an actual event really difficult as you have to sift through hours and hours of footage. Typically it works best when cameras record only on motion sensing. 2.) Why have cameras inside trailer? Would be easier to have cameras on your home aimed at the trailer. That way you can do everthing with wires instead of wireless. 3.) What is the point of viewing inside your trailer as you drive down the road?? If theft of your bike is a concern, cameras inside the trailer is pretty risky. It would be very easy for theif to simply tear down cameras. And that system you linked, the footage is stored in the camera. So if theif takes the camera, he is also taking the recorded footage. Even under a perfect camera set up, understand that cameras only record what has already happened. Your bike is gone, even if you have a face, you may or may not get an ID on the person. Even if police catch them, they may have already pawned or traded bike. They may go to prison, but you will not be reimbursed for bike. Nothing beats physical barries to theft like locks, metal, bars, concrete, etc

here is an example of a a full HD IP system https://www.amazon.com/LaView-Camera-Security-Channel-Resolution/dp/B01HPB4JUS/ref=sr_1_6?ie=UTF8&qid=1483817017&sr=8-6&keywords=8+camera+ip

Why not just get a 4 camera system and put 1 camera in each corner of the barn? You cant really put just 2 cameras on the viewing screen anyway. Usually its one camera and then the next viewing option is 4 cameras. Yes I agree that IP POE is the way to go. I'd probably go with 3MP or 5MP cameras.

I personally wouldnt go to the trouble of installing a system unless it were IP and at least 1080. You get what you pay for. $333 for 8 cameras and a DVR is really cheap. Wait and save up your money and get an IP system.
