I wanted to save some HTML pages as single files that could be read by Chrome and Firefox. I found out that you could do it in Chrome without any extension by enabling the experimental flag Save Page as MHTML . This experimental feature can be found by typing chrome://flags/#save-page-as-mhtml   in the search bar. However, Chrome warns you to be careful with playing with these options: ... you could lose browser data, or compromise your security or privacy. Once you enable this option, you must restart Chrome, and thereafter the files can be saved in the compressed format MHTML, " a single text file containing HTML and all sub-resources ". However, these MHTML files can be read by Chrome, but not by Firefox. Thus I searched for other tools that can generate HTML single files which can be read by both Chrome and Firefox, and these are the two extensions I tried that can accomplish this feat: SingleFile : Install for  Chrome  and Firefox Save Page WE : Install for...

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 ...
