Installing CCTV Cameras

                   
Planning before installing a CCTV camera

The most important aspect of installing a CCTV camera system is choosing the right spots for the camera and DVR to maximize camera coverage and minimize cable length (which in-turn reduces the in line losses that affect video quality). For indoors, choose a corner in the room from where most entry points into the room are visible. 

A power socket should also be in close proximity. 

Mounting the camera

Place the camera unit at the desired place, make guide marks for drilling. Drill holes and hammer in the screw moldings. Now, screw the camera in place firmly. Insert the power cable of the camera in a socket.

Placing the DVR

DVR of the CCTV is the place where the surveillance hard disk is present. Thus all your CCTV recordings reside inside a DVR. It is highly recommended to keep the DVR inside a locked compartment so that even if an intruder spots the DVR, he/she can’t destroy the recorded videos. This is a vital step to ensure a bulletproof security system for your home.

Managing the cables

Plan the pathway for all the cables from cameras to the DVR unit. Use wire moldings to keep the wire managed and safe. Nail the moldings along the path and put the Siamese surveillance wire inside.

Connecting the wires

Steps to connect the BNC port

The video cable is connected via a BNC port. Remove about 1.5cm of the outer covering of the video cable which should now expose the braids. Slide the crimping barrel onto the cable with a wider diameter facing towards the end of the cable. Now remove the white insulator covering the innermost cable. Now insert these exposed cables into the BNC port and screw the crimping barrel. This makes a secure connection. Connect the DVR output port to the screen on which you want the video feed.

Power on the system

Start by powering ON the cameras followed by the display and the DVR. Setup the DVR according to the user manual provided with the DVR. Go over every camera’s feed to confirm each camera is working properly and providing the desired viewing angle.

A domain name is a URL address someone types in a browser to visit a specific website. In simple words, if your home was a website your address would be its domain name. There are dozens of domain extensions but few of them are more famous and they are usually called top-level domains. Top-level domains include (.com, .net, and org extensions) .Hopefully, now you make a clear picture of a domain's definition.

Now let's jump into the different types of domain extensions and their uses:

• .com - this domain extension is a top-level domain and used for commercial and personal sites. It is an expensive domain extension that usually costs $ 5 a year and it goes to several hundred dollars a year depending on the keywords.
• .net - this extension is also a top-level extension. It is recommended for companies involved in Internet infrastructure.
• .org - this is also one of the famous extensions recommended for not-for-profit organizations.

Earn Money with Developing Mobile Apps

Why do you want to build an app?
Mobile applications are a great way for business owners to make improvements to their companies. They are also the perfect platform if you think that your idea will be the next big hit, like Instagram, what's app, Snapchat, or Uber. Regardless of your reason for creating an app, I’m sure you have something in common with other prospective developers.

All of you want to make money. First of all, I recommend you to do some research before you get started building your first app. I’ve seen so many people who were naive enough to think that just because they created an app, it would automatically generate money. That’s not true.

Here’s an analogy. If you start a new business, will it automatically make money? Absolutely not! Fortunately, you’ve come to the right place. As an expert in mobile app development. I have the knowledge and experience to help steer you in the right direction.

Consumers clearly love to use apps, so the opportunity is there. Think of your app like any other business. The easiest way to make money is by keeping the customers happy and keep them coming back.

Ready to start displaying ads in your apps?

There are several ways to monetize your mobile app. You can create a paid app to earn money the moment someone decides to install your app. You can create a free or paid app that also offers in-app purchases for additional features, credits, or functionality. Or you can display ads in your mobile app (via google adsense), which can allow you to earn money through ad clicks by your users or by encouraging your users to upgrade from a free app to a paid app.

Earn money with in-app advertising by displaying ads in different ways.
The key to earning money from displaying ads in your mobile app will be determined by your main revenue generation model - the ad clicks themselves or the upgrade to the paid version of your app.

If ad clicks will be your main revenue generator, then you need to create a free app that will be highly useful or fun to use daily. The ads in your app must be unintrusive, but still bold enough to catch the app user's attention so that while they are using the app, they will still be drawn to the ads to click on them.

Testing your app ad performance.

Ultimately, there's a fine line between displaying ads in your app to reach your revenue goals in a way that gets the job done versus driving away your users before they can either click on your ads.

That is why testing ad display options for your in-app advertising is a must. Test different placements, formats, and the times at which the ads will be shown on your app users to see which ones get the most clicks or upgrades without loss of retention or uninstalls of your app.

Creating a great user experience.
The more testing you do, the more likely you are to find the right balance between revenue generation and a perfect user experience. In addition to monitoring your analytics, be sure to read the comments and reviews about your app. They will tell you the specifics about how your users really feel about your ads and your app as a whole.

Most app creators can find a balance between earning ad revenue through their mobile app and creating a positive experience with their users, which can lead to positive reviews, more users, and more revenue. Good Luck!
