We express our gratitude to the presence of Allah SWT, because thanks to His Grace we were able to complete the Assignment Report 1 for the Distributed Systems Course "Implementation of the CCTV distributed system model in companies".
Understanding Distributed System Models on CCTV
We realize that the Assignment Report 1 of the Distributed System Course is still not perfect, therefore we expect criticism and suggestions from the lecturers and friends to improve the contents of this report. Hopefully, this Assignment Report 1 of the Distributed System Course can be useful for anyone who reads it.
In today's modern era, many large and small companies need more security than just security officers, sometimes security officers are negligent in guarding the security of their company. Therefore, to improve security, the main solution is the addition of CCTV surveillance at certain points. In addition, CCTV can also help the performance of security, which is accessed by security through a local network.
In addition, this CCTV can also be accessed via the internet network, which can make it easier for management or company owners to monitor conditions in the field where CCTV is installed.
Discussion
Nowadays, many DVR products have superior features to monitor CCTV Cameras from Mobile Phones. However, of the many DVRs that I know, only the Infinity brand DVR is very sophisticated and unmatched. There are several features owned by this machine, including:
1. Dual Stream
Dual Stream is a technology commonly used in high-end DVR systems to record high-resolution images locally while simultaneously streaming low-resolution images over the network. Both streams are generated by the DVR, where the main stream has a maximum resolution of up to 4 CIF while the second stream (sub stream) has a maximum resolution of up to CIF.
On Infinity DVR there are main stream and sub stream configurations. Each of these streams is configured to adjust the level of image sharpness and the desired level of streaming smoothness. The configuration on the main stream will affect the sharpness of the recording results and the streaming results via PC/Laptop. The configuration on the sub stream will affect the streaming results via mobile phone and the streaming results via PC/Laptop if the bandwidth used is slow (users can choose to use the main stream/sub stream when they want to stream via PC/Laptop where this is adjusted to their needs).
2. Multi Preview
Monitoring multiple cameras in one software. Now we can monitor up to 64 cameras in one software. With this infinity software we can combine all cameras installed on the Infinity DVR, making it easier for us to monitor / view the condition of the house, company, etc. simultaneously.
3. Zoom Playback
Enlarge the recorded image results. Infinity DVR can enlarge the recorded results (playback) through the Infinity SE software by 4X, thus facilitating the investigation of the authorities if an incident/case occurs.
4. Setting Contrast, Brightness
Adjust lighting and image captions. With Infinity SE software we can adjust contrast, brightness, saturation, so we can get maximum results (if the lighting in the place is poor). This makes it easier for us if the camera is installed where there is no light or lack of light.
5. User Level Access
Limiting access for each user. With this kind of access, it is easier for us to give access authority to each user. Many advanced functions include administrators (supervisor level) who can determine which channels can be accessed by the user.
6. Map
Minimize camera access. With the map feature in the infinity SE software, it is easy for us to monitor homes, offices, and other valuable properties. It is very efficient if you have many Infinity DVRs installed in other places, with this feature it is easy for us to access the camera by simply pressing the HOT SPOT that has been added.
7. Sort group
Sorting multiple cameras to be viewed simultaneously. With the advanced technology of DVR Infinity now we can create groups (select multiple cameras from other DVRs to be displayed as if having 1 DVR).
8. Remote Settings
Setting DVR settings from software. From now on we no longer need to press the DVR remote button, because Infinity DVR can be set remotely or better known as remote setting. This makes it easier for us to set DVR, very efficient if the DVR is far from where we are.
9. Voice Talk & Broadcast
DVR can now send announcements. This feature is very helpful for its users now. By using this we can send announcements to other DVRs, and can also talk with the voice talk feature.
Implementation of CCTV Distributed System
1. How to Install
Starting from the site survey first, then determining strategic points for camera placement, so that the camera has a good focus point. Next, determine the transmission path and DVR (Server) point that is safest from interference. After that, determine the location of the LCD installation, to monitor, and usually placed where the officer can see / monitor. Finally, the installation is carried out.
2. How Infinity CCTV Works
Data is taken from each camera, then sent to the DVR via Coaxial cable, while the power cable is used to supply power / voltage to each CCTV. The data is stored on the HDD inside the DVR. This data can be accessed via a LAN network connected to the Switch, so that the DVR gets an IP address, which will later be used for internet or WAN access.
3. How to Use
Here's an easy way for CCTV users with the Infinity brand, in addition to being able to use the free dns or free dns feature from hiddns, now your Infinity brand CCTV device can use the cloud feature to be able to go online to an android device. The cloud feature here is easier to use. First we must activate the cloud feature on the Infinity DVR device, here as an example we use the Infinity DVR with the 2108 series.
Select Menu, then we will enter the main menu of the Infinity DVR device.
Select Configuration.
Select Network, then mark Enable Cloud, then fill in the Verification Code with ABCDEF.
After that, register the Infinity DVR device on the website www.ezvizlife.com and create a user to be able to log in to the website.
Login to the website www.ezvizlife.com as an example here we use one of our customers, namely Ningrat Printing Kotabumi -- North Lampung.
In the image above, we can see that we can enter the website www.ezvizlife.com, then we can click the play button in the available camera channel box.
If there are no problems with your internet connection, it will appear as in the image above.
For installation on Android devices, you can install the iVMS-4500 application via the Play Store.
Then select Cloud P2P.
Enter the same User Name and Password as when logging in to www.ezvizlife.com, click Auto Login.
After successful login, your Infinity DVR device will appear.
Click Live View
Now your CCTV can be viewed anytime and anywhere via your Android device.
Conclusion
In the context of this distributed CCTV system, we can access data not only through LAN (local), but also through WAN with applications that have been provided on each DVR CCTV product, making it easier for us to monitor certain areas anytime and anywhere, as long as it is available / connected to the internet network and electricity network. Thus, the security of the company becomes more guaranteed.
