There are several modern CCTV cameras who have the ability to act as a web server. Some of the DVRs have LAN port which allows them to connect to a network for both local and remote viewing. For this you must have the understanding about the dynamic and static ip address. For this little understanding of networking and proper configuration is necessary . Hence I advise you to tech help from an expert or tech support engineer

Go for any CCTV camera you wish to buy but an IR illuminator and get installed. This will help you get a better picture quality. I have an Axis camera with an Axton IR illuminator . AT-6E-S is the IR illuminator which I use. This provides a well camera synchronization. It works perfectly and gives a high quality image. IR here are cost efficient and provides a lifetime warranty with advance replacement.

Mainly this is due to low light. During daytime there is enough light and you get a good picture quality. One of the best solutions is to change the lens of your CCTV camera. Use an IR corrected objective lens. This will make the night vision clearer. Any more help needed, please let me know.
