Choose an HDMI Cable

How to Choose an HDMI Cable

Choosing an HDMI cable can be a complex task. There are several factors that must be considered in order to select the best HDMI cable to meet the user’s requirements:
·         HDMI standards compliance
·         HDMI Cable Categories
·         Cable length
·         Cable quality
·         Active cables
·         HDMI devices
·         Price
HDMI Standards Compliance
Each HDMI cable is rated to comply with a specific revision of the HDMI standards. A cable rated for HDMI 1.2a should meet the requirements of HDMI 1.0, 1.1 and 1.2, but is not guaranteed to meet the standards for HDMI 1.3.
HDMI Cable Categories
The HDMI standards define two cable categories. Category 1 HDMI cables support HDTV resolutions and frame rates. Category 2 cables are required for higher resolutions or higher frame rates.
Cable Length
The HDMI specification does not define a maximum cable length. HDMI cables are commonly available in 3′ to 50′ lengths.
Purchasing a cable longer than necessary will cost more money, but it will also increase signal loss due to attenuation.
Cable Quality
All other factors being equal, a cable that is built to higher tolerances using better materials will outperform a cable that is built merely to meet a standards specification. In addition, these premium cables will often provide longer service lives.
An HDMI cable can be made using 28 AWG wire, but a 24 AWG wire will create a sturdier cable that is more resistant to attenuation.
As with traditional analog stereo cables, premium HDMI cables are often furnished with gold plated connectors to ensure the best possible signal quality.
Active Cables
For specialized high end applications, some manufacturers are selling active HDMI cables. These cables use a variety of technologies that involve boosting the transmission distance or quality through the addition of electrical power to the cable connection.
Some of these active cables run over fiber optics or Cat-5 cable.
HDMI Devices
Another approach to supporting extremely long cable runs is to chain multiple HDMI cables together with amplifiers, repeaters, or equalizers.

Cyber Law in INDIA

Cyber Law in INDIA

Cyber law in India is a multi-layered legal framework designed to regulate digital activities, facilitate e-commerce, and punish cybercrimes. As of 2015, the primary legislation remains the Information Technology (IT) Act, 2000, significantly augmented by recent privacy-focused laws like the upcoming Digital Personal Data Protection (DPDP) Act.

Why Cyberlaw in India ? 
When Internet was developed, the founding fathers of Internet hardly had any inclination that Internet could transform itself into an all pervading revolution which could be misused for criminal activities and which required regulation. Today, there are many disturbing things happening in cyberspace. Due to the anonymous nature of the Internet, it is possible to engage into a variety of criminal activities with impunity and people with intelligence, have been grossly misusing this aspect of the Internet to perpetuate criminal activities in cyberspace. Hence the need for Cyberlaws in India.

What is the importance of Cyberlaw ? 

Cyberlaw is important because it touches almost all aspects of transactions and activities on and concerning the Internet, the World Wide Web and Cyberspace. Initially it may seem that Cyberlaws is a very technical field and that it does not have any bearing to most activities in Cyberspace. But the actual truth is that nothing could be further than the truth. Whether we realize it or not, every action and every reaction in Cyberspace has some legal and Cyber legal perspectives.

Does Cyberlaw concern me ? 
Yes, Cyberlaw does concern you. As the nature of Internet is changing and this new medium is being seen as the ultimate medium ever evolved in human history, every activity of yours in Cyberspace can and will have a Cyberlegal perspective. From the time you register your Domain Name, to the time you set up your web site, to the time you promote your website, to the time when you send and receive emails , to the time you conduct electronic commerce transactions on the said site, at every point of time, there are various Cyberlaw issues involved. You may not be bothered about these issues today because you may feel that they are very distant from you and that they do not have an impact on your Cyber activities. But sooner or later, you will have to tighten your belts and take note of Cyberlaw for your own benefit.

Cyberlaw Awareness program 
Are your electronic transactions legally binding and authentic? Are you verifying your customers' identities to prevent identity theft? Does your online terms and conditions have binding effect? Are you providing appropriate information and clear steps for forming and concluding your online transactions? How are you ensuring data protection and information security on your web site? Are you recognising the rights of your data subjects?
Transacting on the Internet has wide legal implications as it alters the conventional methods of doing business. To build enduring relationships with your online customers the legal issues of e-transactions need to be addressed from the onset.

This Awareness program will cover
The basics of Internet Security
basic information on Indian Cyber Law
Impact of technology aided crime
Indian IT Act on covering the legal aspects of all Online Activities
Types of Internet policies required for an Organization.
Minium hardware and software, security measures required in an organization to protect data

Cyber laws are meant to set the definite pattern, some rules and guidelines that defined certain business activities going on through internet legal and certain illegal and hence punishable . The IT Act 2000, the cyber law of India , gives the legal framework so that information is not denied legal effect, validity or enforceability, solely on the ground that it is in the form of electronic records.

One cannot regard government as complete failure in shielding numerous e-commerce activities on the firm basis of which this industry has got to its skies, but then the law cannot be regarded as free from ambiguities.
MMS porn case in which the CEO of bazee.com(an Ebay Company) was arrested for allegedly selling the MMS clips involving school children on its website is the most apt example in this reference. Other cases where the law becomes hazy in its stand includes the case where the newspaper Mid-Daily published the pictures of the Indian actor kissing her boyfriend at the Bombay nightspot and the arrest of Krishan Kumar for illegally using the internet account of Col. (Retd.) J.S. Bajwa.

The IT Act 2000 attempts to change outdated laws and provides ways to deal with cyber crimes. Let’s have an overview of the law where it takes a firm stand and has got successful in the reason for which it was framed.
1. The E-commerce industry carries out its business via transactions and communications done through electronic records . It thus becomes essential that such transactions be made legal . Keeping this point in the consideration, the IT Act 2000 empowers the government departments to accept filing, creating and retention of official documents in the digital format. The Act also puts forward the proposal for setting up the legal framework essential for the authentication and origin of electronic records / communications through digital signature.
2. The Act legalizes the e-mail and gives it the status of being valid form of carrying out communication in India. This implies that e-mails can be duly produced and approved in a court of law , thus can be a regarded as substantial document to carry out legal proceedings.
3. The act also talks about digital signatures and digital records . These have been also awarded the status of being legal and valid means that can form strong basis for launching litigation in a court of law. It invites the corporate companies in the business of being Certifying Authorities for issuing secure Digital Signatures Certificates.
4. The Act now allows Government to issue notification on the web thus heralding e-governance.
5. It eases the task of companies of the filing any form, application or document by laying down the guidelines to be submitted at any appropriate office, authority, body or agency owned or controlled by the government. This will help in saving costs, time and manpower for the corporates.
6. The act also provides statutory remedy to the coporates in case the crime against the accused for breaking into their computer systems or network and damaging and copying the data is proven. The remedy provided by the Act is in the form of monetary damages, not exceeding Rs. 1 crore($200,000).
7. Also the law sets up the Territorial Jurisdiction of the Adjudicating Officers for cyber crimes and the Cyber Regulations Appellate Tribunal.
8. The law has also laid guidelines for providing Internet Services on a license on a non-exclusive basis.

The IT Law 2000, though appears to be self sufficient, it takes mixed stand when it comes to many practical situations. It looses its certainty at many places like:
1. The law misses out completely the issue of Intellectual Property Rights, and makes no provisions whatsoever for copyrighting, trade marking or patenting of electronic information and data. The law even doesn’t talk of the rights and liabilities of domain name holders , the first step of entering into the e-commerce.
2. The law even stays silent over the regulation of electronic payments gateway and segregates the negotiable instruments from the applicability of the IT Act , which may have major effect on the growth of e-commerce in India . It leads to make the banking and financial sectors irresolute in their stands .
3. The act empowers the Deputy Superintendent of Police to look up into the investigations and filling of charge sheet when any case related to cyber law is called. This approach is likely to result in misuse in the context of Corporate India as companies have public offices which would come within the ambit of "public place" under the Act. As a result, companies will not be able to escape potential harassment at the hands of the DSP.
4. Internet is a borderless medium ; it spreads to every corner of the world where life is possible and hence is the cyber criminal. Then how come is it possible to feel relaxed and secured once this law is enforced in the nation??
Primary Legislation: The IT Act, 2000
The IT Act provides the foundational legal structure for all digital interactions in India. 
  • Legal Recognition: It grants legal status to electronic records, online contracts (Section 10A), and digital signatures.
  • E-Governance: Facilitates the filing of electronic documents with government agencies.
  • Penalties for Offenses: It defines specific cybercrimes and their punishments:
    • Hacking/Unauthorized Access (Section 66): Up to 3 years' imprisonment or fine up to ₹5 lakh.
    • Identity Theft (Section 66C): Fraudulent use of digital signatures or passwords.
    • Cyber Terrorism (Section 66F): Threatening national security via computer resources; punishable by up to life imprisonment.
    • Obscene Content (Section 67): Publishing or transmitting obscene material in electronic form

Seven Advantages of IP or Network Camera Surveillance System

Seven Advantages of IP / Network Camera Surveillance System

IP CCTV stands for Internet Protocol Closed Circuit Television. Furthermore, it is also referred to as network or Power-Over-Ethernet (POE) CCTV. IP cameras are digital devices that capture and transmit video footage over a network.

It offers several benefits over analogue systems, such as higher resolution and scalability – more on this later.

IP/Network cameras offer superior image quality, remote access, advanced analytics (AI), easier scalability/installation (PoE), better security with encryption, flexible storage (cloud/NVR), and seamless integration with other systems, making them more versatile and powerful than traditional analog CCTV for modern surveillance needs.

How to Connect an IP Camera to a Computer

 Here are seven key advantages:

1.        Superior Image Quality: Deliver high-definition (HD) or even megapixel resolution with clearer, more detailed images and better digital zoom capabilities.

IP-based CCTV cameras can capture and transmit higher quality images than standard analogue systems. Furthermore, with IP cameras you can zoom in on your footage with greater clarity.

In context, this is highly valuable to a business, particularly when looking to identify an individual, specific characteristics, car number plates and more.

2.        Remote Access & Monitoring: Remote monitoring is made easier by IP security cameras. For example, you can effortlessly see live footage from your computer, tablet, or smartphone anywhere you are with a wireless IP camera in Dubai. Homeowners who wish to check in on their property while abroad or company owners who need to monitor several sites will find this function especially helpful. View live feeds and recorded footage from anywhere via the internet, offering unparalleled flexibility for home or business.

3.        Advanced Video Analytics: Built-in intelligence for features like motion detection, visitor counting, facial recognition, and anomaly detection, reducing manual monitoring.

Your security camera systems can be set up to detect:

·        Smoke

·        Fire

·        Movement of people

·        Change in temperature

For example, if your security cameras are fitted with movement sensors, you will be alerted if the system detects a threat. As a result, your security team can view the footage in real-time. If a security threat is spotted, the relevant action is taken.

If your CCTV system is monitored remotely, your off-site security team will take charge of the situation.

4.        Scalability & Flexibility: Easily add cameras to an existing network and reposition them, using existing network infrastructure (like CAT5/6 cables).

5.        Power over Ethernet (PoE):  A single Ethernet cable provides both power and data, simplifying installation and reducing cable clutter.

6.        Enhanced Security: The majority of IP cameras come with built-in encryption. This helps to keep your data safer when it is transmitted and stored.

Cyber attacks are becoming more of a threat to businesses, month by month, year by year. Securing your data will help protect it from ending up in the wrong hands.

Digital encryption protects video data from unauthorized access, ensuring privacy and secure transmission.

7.        Smart Integration & Storage: Can integrate with other security systems and offer convenient, secure digital storage (cloud or NVR), making data management efficient.

Frequently asked questions

What is a network video surveillance system?

A system of data transmission from video cameras, which is carried out via the Internet, will be considered a network. In this case, both global networks and local ones can be created.

Mandatory network system design:

·        video cameras (analog and/or IP, PTZ cameras);

·        equipment for data processing and storage of video recordings: recorders, servers, computers, hard drives, switches;

·        special software.

Until recently, it was believed that such an organization of video systems is the optimal solution for continuous monitoring of facilities and events. Many users have chosen network surveillance cameras because of their efficiency and simplicity.

IMPORTANT: Analog, IP and CCTV cameras have a number of differences. CCTV (Closed Circuit Television), as a modern generation closed loop system, is no longer analog equipment, and if CCTV is connected to a DVR, it becomes an IP camera.

What is an IP CCTV system and how does it work?

An IP CCTV system uses digital cameras that transmit video over an internet protocol (IP) network. Unlike analogue systems, IP cameras can stream high-definition footage directly to a recorder, computer, or cloud platform for real-time or recorded viewing.

How is image quality improved with IP CCTV cameras?

IP cameras typically offer higher resolution than analogue, with many supporting 1080p, 4K, or even greater. This results in sharper images, better zoom capabilities, and clearer identification of faces, licence plates, and other critical visual details.

Can I access IP CCTV footage remotely?

Yes. One of the main benefits of IP systems is remote access. Users can view live or recorded footage securely via mobile apps or web browsers, allowing for flexible monitoring from anywhere with an internet connection.

Are IP CCTV systems scalable for growing businesses?

Absolutely. IP systems are highly scalable—new cameras can be added with minimal disruption using existing network infrastructure. This flexibility makes them ideal for businesses expecting to expand or reconfigure their premises.

How is footage stored in an IP CCTV system?

Footage can be stored locally on an NVR (network video recorder), in the cloud, or using a hybrid approach. Cloud storage enables off-site backup and remote access, reducing the risk of footage loss through theft or damage.

What smart features are available with IP CCTV systems?

IP systems often include motion detection, line-crossing alerts, intrusion zones, facial recognition, and two-way audio. These intelligent analytics help reduce false alarms and enable proactive security management based on real-time activity.

How does an IP CCTV system compare to analogue CCTV in cost?

IP systems may have a higher upfront cost, but they offer greater long-term value due to superior image quality, scalability, and advanced features. Over time, they reduce maintenance and upgrade costs compared to ageing analogue setups.

4 disadvantages of the network system

Check out the disadvantages of a network video monitoring system:

1.        Requires technically competent system planning and professional installation. It is necessary to keep in mind the compatibility of equipment, lighting parameters, capabilities of the coaxial cable between the network nodes, height and angle of the cameras.

2.        Video signal delays are possible during data transmission and viewing recordings in real time.

3.        High cost of equipment, including license payment for each camera.

4.        High cost of installation, configuration and regular maintenance of the system (2-3 times more expensive than other video surveillance systems).

What type of network does IP cameras use?

Understanding the concept of what an IP camera is will help you easily choose the appropriate type of network connection. IP smart camera systems can operate on many different types of networks, the most popular are the following three types:

·        Wired network: Connect directly to a modem or broadband router via Ethernet cable (RJ45, CAT5, CAT6). This is the fastest and safest way to connect to eliminate the risk of signal interference and information disclosure.

·        Wireless network: IP cameras use a WiFi router to transmit data to and from a wired modem. Wireless networks have slower data transmission speeds than wired networks and are at higher risk of unauthorized access. However, using strong encryption and network customization can minimize this risk.

·        Cellular network: IP cameras can use cellular connections to transmit data. Although data transfer speeds are typically slower than WiFi, mobile networks are more secure and do not require LAN settings. However, these types of cameras are often more expensive.

Should I install an IP camera system or not?

In addition to understanding what an IP camera is, many users also wonder whether they should install an IP camera system or not. The answer is yes! Installing an IP camera system brings many benefits and is an effective security solution for every home, agency, office, and company. Here are some reasons you cannot ignore installing IP cameras:

·        IP cameras eliminate all old faulty hardware, instead using powerful NVR software, which helps manage data and images effectively.

·        The IP camera line delivers extremely clear HD images with high resolution from 720p, 1080p, compared to PAL, CIF, NTSC standard versions on Analog Cameras. This helps the device record every moment and convert the video into a digital stream before transmitting the signal.

·        IP camera equipment allows simple and easy remote observation and control. You can rest assured about the safety of your home, even when you go on business or pleasure trips.


Installing IP cameras is an effective solution to protect family and property security. However, to ensure the camera system operates effectively and safely, you need to pay attention to the following important issues:

·        Choose a reputable installation unit: Choose a reputable and professional installation unit to ensure the construction work is done quickly, safely and effectively. You need to follow the installation process from start to finish and request instructions on how to use it and change your password login information.

·        Check the installation location: Make sure to choose an installation location so that the camera can observe every corner of the area to be monitored. For infrared IP cameras installed outdoors, you should choose a location that is resistant to water, dust and high temperatures.

·        Ensure stable network source: For wifi IP cameras, it is necessary to ensure fast and stable network speed to avoid affecting image quality and video transmission speed. With wired cameras, use good transmission cables to ensure the system operates smoothly and with quality.

PTZ camera advantages & Disadvantages

PTZ camera advantages & Disadvantages

PTZ cameras occupy a special place in the field of video surveillance. So, here’s an article which will throw some light on how these cameras can prove useful, what are their deployment pros and cons and other related points.
Basically, a PTZ security camera is a network camera which reflects the movement options of Pan, Tilt and Zoom. These cameras can be mechanically operated, where the user typically has the ability to control the Pan-L and R (Rotate Vertically); Tilt- Up & down (Move Horizontally); and Zoom (Point Down an objects) of the camera with a joy stick / Key Board / hardware device or another software.

PTZ cameras are ideal choice for monitoring large public places like stadiums, traffic signals, and other environments. If these cameras come tucked with the feature of megapixel or high definition (which is now possible in 2015), then they add absolute value to the whole deployment security surveillance.
Coming to the Pros and Cons of PTZ cameras, here’s a bit of illustration-

PTZ camera advantages
1. With the help of a capable VMS, the PTZ cameras can be auto programmed. So, these cams can capture the front doors, the gate and the fence at regular intervals and can achieve the best out of it.
2. If the video from this camera is under live monitoring then an operator can track down a suspect or respond to a threat triggered by the video management software integrated with the camera. The operator can then zoom-in and take control of the situation and if necessary can act in time for loss prevention. If the PTZ camera is tucked with high definition, then the captured image can help the operator track the facial features of a suspect, license plate of an automobile involved in crime or identify an object of interest.
3. As these security cameras can be panned, zoomed and tilted, hundreds of acres of land can be monitored day/night. So, by using a PTZ in premises, the cost of coverage per given area can get reduced.


PTZ camera Disadvantages
1. As every technology has its pros and cons, so does the PTZ camera. Generally, people gather an opinion that these cameras are capable of covering 360 degrees. Except for a couple of cameras available in the market of this sort none can truly cover up more than 180 degrees. So, go for a demo if the camera PTZ maker claims to make a camera with not just 360 degrees coverage.
2. The other disadvantage which can prove advantageous to criminals is that these cameras record where the lens is focused. So, if an incident occurs and if the camera is pointed in other direction, then it could potentially miss the event entirely and this could miss vital video evidence.
3. Though, there is a lot of development in PTZ cameras offered by different manufactures, it is often observed that they need to be regularly maintained and have a shorter life span. Moreover, most installers feel that in hot conditions, these cameras will give-up. But yes, if they are secured in a housing which keeps the inside temperature under control, then these cameras tend to work fine.
4. The sensors of PTZ cameras are smaller when compared to fixed cameras. So, image quality is not up to the mark. But as technology improvisation is taking place is this segment, it is reviewed to be yielding better results.
5. To get the best out of a PTZ camera monitoring, a live operator dedicated to monitor the system is needed. So, here a rise in surveillance costs can be observed.
6. If the PTZ camera is not properly installed, then a slight wind can push the video output into doldrums. So, the installer must be very careful in such camera deployments.
7. PTZ cameras if positioned in unwanted places can land the installer and the owner installing the equipment into legal trouble. And if their focus includes the coverage of an opposite house swimming pool or lawn even by an inch, then the installer and the related authorities will be in deep trouble.
8. PTZ controls are sensitive to latency and if the latency is more than a fraction of second, then the PTZ control can go out of gear.
9. PTZ cameras have more features in them and so their cost is 60% high than normal fixed cameras.
10. The position of a PTZ camera will indicate the focus of its lens. So, an attacker can creep into the blind spot of the camera and spray some paint on the camera lens, in order to prevent the camera from recording further. There is a high chance that the image of the person doing such mischief can get skipped.
Therefore, in order to get optimal results from PTZ camera deployment these cameras can be made as a supplementary with fixed cameras for investigating a situation or tracking a criminal.

Hope, this article helps in unraveling the truth about PTZ security cameras.

720p and 1080p explained

720p explained
720p is the shorthand name for a category of HDTV video modes. The number 720 stands for the 720 horizontal scan lines of display resolution (also known as 720 pixels of vertical resolution), while the letter p stands for progressive scan or non-interlaced.

Progressive scanning reduces the need to prevent flicker by filtering out fine details, so sharpness is much closer to 1080i than the number of scan lines would suggest. A 720p frame has about 1 million pixels. Compared to it, a 1080p frame has 2 million pixels so the amount of detail doubles. However in practice the difference between 1080p vs 720p is not as obvious as the one between standard definition vs high definition (480p vs 720p). For example a regular DVD isn’t even considered high definition because it is either 720×480 (NTSC) or 720×576 (PAL) but it looks much better than regular NTSC or PAL TV broadcasts and not as great as 720p. That being said, you do get more detail from 1080p than from any resolution if you have the “winning” formula for screen size, resolution and viewing distance – that is if you have the optimum conditions to get the most out of 1080p.

1080p explained:
The number 1080 represents 1,080 lines of vertical resolutions (1,080 horizontal scan lines), while the letter p stands for
progressive scan (meaning the image is not interlaced). 1080p can be referred to as full HD or full high definition although 1080i is also “Full HD” (1920×1080 pixels). The term usually assumes a widescreen aspect ratio of 16:9, implying a horizontal resolution of 1920 pixels. This creates a frame resolution of 1920×1080, or 2,073,600 pixels in total.

The only pure 1080p content comes from high definition DVDs like Blue Ray and HD DVD. Regular DVDs are way below that, having just 480p or 576p. You also get HD content from TV broadcasts but for now only 1080i and 720p. Basically 1080i offers pretty much the same amount of detail as 1080p but the quality of fast moving scenes is a bit inferior to 1080p. To understand this better read the 1080p vs 1080i guide. 720p content will of course look the same (or very similar) on a 1080p screen as it does on a 720p screen because what also matters is the content resolution not just the screen resolution.

Here is a sample with the difference between 720p and 1080p:
480i - Total image resolution 337,920 pixels
480p - Total image resolution 337,920 pixels
720p - Total image resolution 921,600 pixels (roughly equivalent to a 1 mega pixel camera)
1080i - Total image resolution 2,073,600 pixels (equivalent to a 2 mega pixel camera)
1080p - Total image resolution 2,073,600 pixels (equivalent to a 2 mega pixel camera)

More lines is nice but don't forget about the 'p' and 'i' in the 720p, 1080i and 1080p. The letter is an abbreviation for the type of scan the TV uses -- 'p' stands for progressive and 'i' stands for interlaced.

1000BASE-TX over CAT 6

1000BASE-TX over Category 6

TIA/EIA-854 : A Full Duplex Ethernet Physical Layer Specification for 1000Mb/s operating over Category 6 Balanced Twisted Pair Cabling (1000BASE-TX).

This document specifies a full duplex Ethernet physical layer interface for 1000Mb/s operation over a 100 meters of a Category 6 twisted pair cabling channel, referred to as 1000BASE-TX.

The purpose of this document, 1000BASE-TX, is to provide an Ethernet physical layer specification that is low complexity and can easily be implemented by many vendors. This will take advantage of the improved transmission parameters provided by Category 6 cabling.

It was believed by the members of this project that a much simpler solution for data rates of 1000Mb/s operating over a 100 meters of Category 6 UTP cabling would be a benefit to users who migrate to the higher data rates. It would eliminate the complicated requirements in the 1000BASE-T standard of canceling the effects of crosstalk and return loss, providing a solution that could operate at a much lower power level, the potential for multiple ports per chip, and could be implemented at a lower cost.  As it turned out, the ports became cheap very quickly and so no hardware vendor adopted this standard.

ANSI decided not to adopt TIA/EIA-854. The IEEE also decided not to adopt this and keep with 1000BASE-T as in IEEE802.3ab.

Since there is no application for this limit and it was not adopted by either ANSI or IEEE, it is not in the DTX CableAnalyzer.
