You can chose the Hikvison 3MP IP camera and the NVR.

I thinkg you can try the brand Hikvision, you will be surprice with its price and quality.

My suggestion is that you can connect the camera to your PC first and try to visit it by browser.

No, it is not normal, if the enviroment is too dark, the picture will be total black and white, there should not be some color band. ​

I think the problem is the power supply. according to your picture, the power supply is not "clean" which is kind of old. My suggestion is that you can use the UPS battery supply.

In my imagination, there will be a glasses(the google glass is a elemantary product) which can help human to check everything, such as what is the material of a stone, how deep is a pool , how many people in a away house, like a sicience fiction movie. Also, it can help to do face recognition, if you made a new friend a month ago, and suddendly meet him on the street while you can not remember whether he is your friend, the glass with the camera can help you.

Hi,my suggestion is that you can use the products below Hikvision DS-2CD2432F-IW 4PCS which can help you to set alarm system too for your home Hikvision DS-2CD2732F-I 4PCS which support Vari-focal Lens Hikvision DS-7608NI-SE/P 1PCS which can be installed 4TB hard drive

According to your cameras are Hikvision, i recommend you can chose the DS-7608NI-SE/P which support 4TB hard drive and allow your customer to view cameras easily. And it will be just $392 on nasasafe

My suggestion is that you can chose IP cameras and NVR. It will be easy to install and use,but the internet information fee will be higher

You need tell me the model of your DVR. Maybe your meaning is recording off line,if you want to do that,do not need setting in the DVR,just copy from one HDD drive to another

The DVR manufacture will always provide the IP address,you can find it on the box of the product. Or if there is not,you can use the PenatHull to make your IP address static.

Maybe you can tell me more details you require, I will recommend some ones to you.

Maybe you can ask the after sale of the Dahua, they will help you

I think it will be easy to find one on amazon, but at first, maybe you need to know how much your budget is. My suggestion is you should never buy dash DVR which is lower than $40.

I think RG 59 is more suitable for you
