Spring MVC Framework Using Hateoas

Spring MVC Rest is the framework to develop the services using Json, it provides only plain response, and it will not point to the other rest links. Spring Rest framework clients will tightly depends on provider as they it need to by provider if any modifications to rest endpoints.

Spring Hateoas(Hypertext as the Engine of Application State) is the framework it resolves most of the dependent issues, by providing hyperlinks to inner/linked resource.
Spring MVC Framework Using Hateoas
If we know the initial/staring URI of the service, all different application endpoints can easily understood the client by parsing the initial response.

Some of the Classes used in Hateoas: 

1.Link: it is the classes used to create hyperlinks, it has two fields, rel and href. Href property points to hyperlink and rel contains hyperlink type like self, next etc.

Link link = new Link("http://localhost:8080/test");

assertThat(link.getHref(), is("http://localhost:8080/test"));

assertThat(link.getRel(), is(Link.SELF));

2.Resource Support: It is the base class containing all hyperlinks for a data transfer objects.

Example:

public class StudentResource extends ResourceSupport {
              long id;
              String firstname;
              String lastname;
              // setters and getters
            }
            StudentResource resource = new StudentResource();
            resource.id=1L;
            resource.firstname = "Dave";
            resource.lastname = "Matthews";
            resource.add(new Link("http://myhost/student"));
            The output will be 
            {
              "id":1,
              "firstname": "Sravan",
              "lastname": "K",
              "links": [
                {
                  "rel": "self",
                  "href": "http://myhost/student"
                }
              ]
            }
            

3.LinkBuilder: It is the interface is used for creating links at different application layers.LinkBuilderSupport is the abstract class provides the abstract implementations of interface.

ControllerLinkBuilder is the class used to link using spring rest controller methods.

Example:

Suppose if the controller contains below methods:

@Controller
            @RequestMapping("/students")
            class StudentController {
            
              @RequestMapping(method = RequestMethod.GET)
              public HttpEntity<StudentResource> showAll() {}
            
              @RequestMapping(value = "/{studentId}", method = RequestMethod.GET)
              public HttpEntity<StudentResource> show(@PathVariable Long studentId) {}
            }
            
Link link = linkTo (StudentController.class).withRel("students"); is the link points to first method and

Link link = linkTo (StudentController.class).slash(student.getId()).withSelfRel(); is the link to points second method, to show the student id url.

ControllerLinkBuilder internally depends up on ServletUricomponentBuilder an extension of UricomponentBuilder which is used to prepare the absolute uri of the link.

The slash method will accept either object or any object which implements the org.springframework.hateoas.Identifiable interface, then we can pass the object instead of object property, by default it will call getId() method instead of toString() method.

 Student student = new Student(1L, "Dave", "Matthews");
                    

Link link = linkTo(StudentController.class).slash(student.getId()).withSelfRel();

If the Student class implements Identifiable interface then

 Student student = new Student(1L, "Dave", "Matthews");
        

Link link = linkTo(StudentController.class).slash(student).withSelfRel();

AnnotationMappingDiscoverer is the class is used to discover the @requestMapping annotation method and also @RequestParam, @PathVariable and @MatrixVariable etc… While creating links.

methodOn() method present in ControllerLinkBuilder class which will return proxy for dummy method implementation.

The framework passed into the methods are typicallyignored, exclude the ones mention to through @PathVariable as they create up the URI.

EntityLinks: EntityLinks is the easier way to create hyperlinks, it will not depends on controller methods, it will only depends on entities.

EntityLinks is available for dependency injection by activating @EnableEntityLinks in Spring MVC configuration.

Activating this functionality will cause all Spring MVC controllers and JAX-RS resource implementations available in the current ApplicationContext being inspected for the @ExposesResourceFor(…) annotation. 

The annotation exposes which model type the controller manages. The annotation exposes which model type the controller manages. 

Beyond that we assume you follow the URI mapping convention of a class level base mapping and assuming you have controller methods handling an appended /{id}.

Sample Controller look like below:

@Controller
            @ExposesResourceFor(Order.class)
            @RequestMapping("/orders")
            class OrderController {
            
              @RequestMapping
              ResponseEntity orders() {  }
            
              @RequestMapping("/{id}")
              ResponseEntity order (@PathVariable ("id") ){}
            }
            
            And the entityLinks in other controller:
            
            @Controller
            class PaymentController {
            
              @Autowired EntityLinks entityLinks;
            
              @RequestMapping(, method = HttpMethod.PUT)
              ResponseEntity payment(@PathVariable Long orderId) {
            
                Link link = entityLinks.linkToSingleResource(Order.class, orderId);
                
              }
            }
            

ResourceAssemblerSupport is the class to create resource links, for single and all resources.

StudentResourceAssembler:

class StudentResourceAssembler extends ResourceAssemblerSupport<Student, StudentResource> {
            
              public StudentResourceAssembler() {
                super(StudentController.class, StudentResource.class);
              }
            
              @Override
              public StudentResource toResource(Student student) {
            
                StudentResource resource = createResource(student);
                // … do further mapping
                return resource;
              }
            }
            

And the link creation will be:

Student student = new Student();
            Iterable<Student> people = Collections.singletonList(student);
            StudentResourceAssembler assembler = new StudentResourceAssembler();
            StudentResource resource = assembler.toResource(student);
            List<StudentResource> resources = assembler.toResources(people);
            

Conclusion:

Spring Hateoas is the frameworks for providing the hypermedia link in response, client need the single point of the entry point of the provider, and inner/linked resource will get the previous response,

so that if the provider endpoints are modified then also client cannot modify their code, Also, the application can advertise new capabilities by putting new links or URIs in the representation.

PTZ vs Rotating Security Cameras

There are various types of security cameras two of which are PTZ and rotating security cameras. A PTZ camera is generally thought of as a security camera with pan, tilt, and zoom functionality, and a rotating security camera has practically the same functionalities as PTZ without the Z or the zoom functionality.

While both security camera types seem to possess extreme similarities, there are small differences of great significance, which depend on the purpose the security camera needs to achieve.

Rotating Security Cameras
For indoor location that are of a moderate size, like a home or other private spaces, rotating security cameras are ideal. Its functionality of panning and tilting can be done manually or through an app on a smartphone or tablet.
Panning allows the camera to swirl to the left and right, increasing the area of coverage horizontally up a complete 360-degree coverage. Tilting on the other hand, allows the camera to move up and down, expanding the range of coverage vertically up to 180 degrees. The range of pan and tilt varies by security camera.

PTZ
PTZ are ideal for large areas such as car parks, businesses, schools, sports' fields and so on. However, whether they are used in the home or commercial/public spaces, the freedom of movement that PTZ offer allow individuals to keep a watch over almost the entire surface of the area.

PTZ security cameras can be manually controlled via an app or a monitoring software that will automatically move the camera to user-determined areas based on a schedule. If the camera has motion detection, then it will automatically move,  bringing the source of the movement into its field of view.

PTZ security cameras have the panning and tilting functionalities mentioned above, but also provide a zooming functionality, which adjusts the security camera’s lens by zooming in and out to enhance the image quality and provide an individual with greater detail of the event in question.


What’s the Appeal?
PTZ and rotating cameras offer an extension on the functionalities and flexibilities of regular security cameras (alerts, night vision, audio, etc). PTZ and rotating cameras are often combined with fixed security cameras, particularly when used in a large area.

The fixed security cameras may monitor locations like entrances, key areas in question or with heightened potential for events, while the rotating or PTZ security cameras may capture general information as they tilt and pan - with PTZ also being able to provide higher detailed images as it zooms on an object or an event.

Rotating cameras and PTZ come in various styles and are often suitable for both indoor and outdoor use. Rotating cameras are often known for their high-speed panning and tilting which allows one camera to monitor a relatively wide area, while also reducing or eliminating the blind spot completely.

As we summarize the key features of these two security camera types, keep in mind the purpose for which the security camera will be used: 

> PTZ tend to be larger in size compared to rotating and traditional cameras.
> PTZ cameras are also heavier and carry more bulk.
> Rotating cameras have pan and tilt, but no zoom functionality, while PTZ is equipped with all three.
> Rotating and PTZ cameras offer manual and automatic controls.
> Rotating security cameras are ideal for homes or other moderate size private areas.
> PTZ cameras are more popular in larger spaces and outdoors.
> PTZ camera's zoom function may be compromised with the result of blurry images.
> A quality PTZ camera should have an automated focus to avoid blurry images when zooming on an event.
> Both camera types can be combined with other camera types for enhanced video surveillance.
> PTZ cameras tend to be higher in price when compared to rotating security cameras. 

Best Security Cameras Under 100 Pounds

What constitutes a security camera to be the best? While the answer depends on the needs of the security camera owner, there are some basic features and functions that ideal security cameras possess.

Motion Detection
Motion detection is one of the most important features on a security camera, particularly a home security camera. The security camera’s built-in sensor can detect movement (only within the field of view), which can then lead to an alert, or trigger video recording.
If the camera has this feature it is important to also have the capacity to adjust sensitivity and the range of the field of view. If this capacity is lacking, then false alerts might become typical and frequent.

Alerts
The alert function is another critical feature on a home security camera. This is a valuable feature that will allow you to be aware of any suspicious movements or events without having you monitor the video feed continuously.

Depending on the setting and capacity of the security camera, you may receive emails and/or alert texts when motion, sound, and/or a face is detected. Face recognition is quite useful particularly if the security camera is to be used at home.

Apps
The app that is compatible with a security camera allows an individual to access the video feed, receive emails and alerts, and even control the security camera by manually recording using the App, control the motion detection, sound sensitivity, audio speech and more.

Night Vision
We feel most vulnerable at night, and most break-ins occur after nightfall. Thus, a night vision feature is always in demand. Most security cameras offer infrared LED illumination, as opposed to night vision based on thermal vision.

There are security cameras that can automatically detect change in light and trigger night vision, while others need to be customised to indicate a time for the night vision to take over.

Resolution
A security camera is useless if you cannot understand what is happening within the field of view. Blurry or distorted images will increase false alerts, while the video recording will be useless in case of an actual event or as evidence.

It is therefore, critical to have a security camera with a high resolution. With a high resolution, there are some sacrifices that must be made, including greater use of internet and Wi-Fi bandwidth and battery life.

If security cameras with high resolutions fall out of your budget, the zoom feature may be an adequate supplement.

These features do not automatically call for a higher price. The features and specifications mentioned above can be found on security cameras that are under 100 pounds. Below are some examples of the best security cameras under 100 pounds:

TIME2 Wireless IP Home Security Camera HD With Night Vision
This security camera offers all the critical features while keeping the price under 100 pounds. It offers a full 720p HD on the PC or Smartphone App with live video stream. It also hosts motion detection, night vision with enhanced display during low light periods (automatic night vision trigger setting)

and even audio sensors, meaning that the security camera can capture high quality feed during suspicious events, with immediate alerts to your device. With its built-in speaker and microphone, you can not only receive audio feedback but also communicate through the security camera. The camera also tilts and rotates for an expandable field of view.

How to optimize YouTube videos for SEO?

It has been more than a decade since YouTube came into existence. From a mere video browsing platform, YouTube has grown to become the second biggest search engine after Google.

Keeping this in view, businesses all over the World see the platform as an amazing opportunity to reach the wider audiences.

Along with the business firms, there are quite a few people who earn money by getting views over their YouTube videos.

However, getting views over a video is not that easy as it seems to be until and unless the video has been uploaded by a well recognized company or brand.

Therefore, it is important that just like a website, a YouTube video also has to be search engine optimized.


In this post, we are going to highlight some of the ways that will enable you to optimize the YouTube videos for SEO.

Keyword Rich Description
While drafting the description of your video, the initial lines are of utmost importance. These lines should cover the theme of the video and basically what the viewers are going to find once they click on the video.

The description should consist of the common keyword phrases that the users are going to type in order to search the video.

 In a case where the search keywords match with the initial lines of the description, the video is definitely going to rank higher in the search results. 

Video's Title Should Match Its Content
The title of the video must be such which gives a clear idea to the views as to what they are going to watch once they click on it.

A title that matches perfectly with the video's content will be friendly for the YouTube's algorithm for SEO and also to the viewers.

The best way to choose a title is to take assistance from the auto complete feature of the search engines. By typing a few keywords that relate to your video's content you will be able to find the keywords that can be used in the title of the video. 

Add Tags In Your Video
Tags play a crucial role in making a video rank higher in the YouTube search results. For putting tags in a video it is necessary to list the specific tags first. By using the main keyword all the weight will be put in the algorithms.

Along with specifying the tags, it is important to list the general tags also. For finding the right tags that are to be used with a video you can also take assistance from a few tools.

These tools also display the ranking with respect to the specific keywords. 

Before Uploading Name The Video File 
So, finally, you have created your video and are eager to upload it to YouTube. But before doing so, you need to rename the video file that consists of the focused keyword.

By doing this, you will be able to give an idea to the search engines as to what the video is all about.

As search engines won't be able to know the actual content of the video, it is the file name that will tell the search algorithms about the content of the video.

By keeping the name of the video file similar to its title will enable the search engines to index the video that will make it rank higher in the search results.

Conclusion
Above-mentioned are few of the tips or ways that will help you in making a YouTube video search engine optimized and in achieving a higher rank for it.

However, initially, all your focus must be on creating a video that is interesting and enticing for the viewers. Once this has been achieved by you, then shift all your focus in the getting the SEO right for it.
