Here is a tentative reading list about automated visual systems  (e.g. object detection, tracking, and recognition): T. Bouwmans, N. Aybat, and E. Zahzah. Handbook on  "Robust Low-Rank and Sparse Matrix Decomposition: Applications in Image and Video Processing" , CRC Press, Taylor and Francis Group, May 2016: "shows you how robust subspace learning and tracking by decomposition into low-rank and sparse matrices provide a suitable framework for computer vision applications." T. Bouwmans, F. Porikli, B. Horferlin, A. Vacavant, Handbook on "Background Modeling and Foreground Detection for Video Surveillance: Traditional and Recent Approaches, Implementations, Benchmarking and Evaluation" , CRC Press, Taylor and Francis Group, June 2014:  "provides a complete overview of the concepts, algorithms, and applications related to background modeling and foreground detection."

Following the installation of a security camera system , I wanted to connect a second VGA monitor in a separate room from the NVR. I decided to use a VGA splitter cable  (1 male 15-pin VGA to 2 female 15-pin VGA connectors) and a 25 Feet VGA cable to connect to this second monitor. Thus, the connection diagram looks like this: VGA splitter cable: splits VGA output signal from NVR to two monitors I tested the video quality on both monitors, and as soon as I connected the second monitor, you could notice a slight decrease in brightness on both monitors. Something I expected since the splitter cable doesn't come with an in-built signal booster. Thus you are loosing power when the original signal is split in two. In my case, the slight decrease in brightness doesn't bother me, but if you find that the quality of the video signal is too bad (e.g. blurry video, video too dark), then I suggest to buy a VGA splitter cable with an integrated signal booster. Also,...

I bought a security camera system from SMONET which consists of 4 wireless [1] bullet IP cameras with night vision: each camera comes with its power adapter [2] . There is an optional Ethernet port on each camera. The camera has an image resolution of 1280*960P . An NVR (Network Video Recorder) system: it comes with its power adapter, a mouse, and an Ethernet cable to connect the NVR to a router. In the Amazon product page  (product description section), they talk about 2 USB2.0 Port but my NVR only has 1 USB2.0 Port in the back, and you can also see it in the user manual  (page 3) that there is only one USB2.0 Port in the back of the NVR. This NVR doesn't come with a hard drive; you have to buy it separately. It is important to stress that if you plan on having a robust security camera system that is very reliable and secure 24 hours a day, 7 days a week, you should opt for a wired security camera system. This wireless security camera system allows you to change ...
