VGA splitter cable

-
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, since the NVR comes also with an HDMI output, you could connect multiple TVs with a HDMI splitter with 2 outputs and more.

Deactivate conda's base environment on startup

When opening a terminal session, conda activates the base environment by default. If you want to prevent this default behaviour, you have three ways: Trick #1  :  Set the auto_activate_base parameter to false Trick #2  : Add conda deactivate in your bash configuration file Trick #3  :  Comment out some part of the conda initialisation code block in your bash configuration file NOTES: I'm working with  conda version 4.7.5 and  miniconda3 (it should also work with anaconda ). These tricks also worked with  conda version 4.6.14 After installing conda 4.7, conda added this block of code in my ~/.bash_profile : This is the block of code that we will modify in the following tricks Trick #1: set auto_activate_base  to false Per conda's instructions, "if you'd prefer that conda's base environment not be activated on startup, set the auto_activate_base parameter to false". Thus, enter the following command in a terminal: c...

Product review: SMONET wireless security camera system

-
Image
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 ...
