Ensuring Network Security System For Surveillance System:

September 21st, 2019

Security camera systems are increasingly internet connected, driven in great part by customer demand for remote video access. The systems range from cloud-managed surveillance systems, traditional DVR/VMS/NVRs connected to the internet, and traditional systems connected to a local network which in turn is connected to the internet.

With cyber-attacks accelerating, physical security integrator and internal support staff must keep up-to-date on cyber security attack vectors which can impact the camera video management systems they sell and/or support. These systems require the same level of protection from cyber security vulnerabilities given to traditional IT systems.

The best practices for internet-connected security camera systems.

  1. Physical Security: A Dangerous Door for Cyber Attacks:

Security Camera Systems are increasingly internet connected, driven by the desire for remote access and control, integration, and drastically reduced cloud storage costs.

In addition to the growing number of cloud-managed surveillance systems, most traditional security camera systems are now connected to the internet for remote access, support, and maintenance, or they are connected to the local network which in turn is connected to the internet.

In parallel, cyber-attacks continue to escalate. Reading about millions of breaches in the news headlines are becoming commonplace. Liabilities for damages are a great risk to companies.

Thus it is critical that security camera systems get the same level of attention to, and protection from, cyber security vulnerabilities that are given to traditional IT systems.

Physical security integrator and internal support staff must keep up-to-date on cyber security attack vectors which can impact the camera video management systems they sell.


  1. Major Attack Vectors for Security Camera Systems:

The five major cyber-attack vectors for surveillance camera systems are:

Windows OS

Linux OS


Endpoints (Cameras)

Firewall ports

We will discuss these attack vectors in context of applicable best practices which can be deployed to protecting your surveillance system against them.


  1. Best Practices Differ Based on Surveillance System Type:


The term ‘cloud video surveillance’ and cloud system’ is used inconsistently. Thus it is important to check with your provider to see exactly how they achieve internet access, as it will impact which steps you must take to ensure your system is secure.

A traditional system, either DVR, NVR or VMS, with an internet connection, typically for the purpose of remote video access.

A cloud-managed system, also called VSAAS. With a cloud-managed system, though there may be an onsite device, the video is recording and managed from the cloud.

There are differences within each of these categories that impact features and functions, however, this top-level distinction will offer clarity in how you can apply cyber security best practices, as well as what questions to ask your provider.


  1. Best Practices for Cyber-Safe Security Camera Systems:


At first glance, camera passwords may seem like too obvious a security measure to discuss. However, a Network World article in November 2014, cited that 73,011 locations with IP Cameras from 256 countries were exposed on one website. The United States topped the list with 11,046 links, where each link could have up to 8 or 16 cameras.

Further,, it is estimated that 1 in 5 Web users still use easy-to-hack passwords.

The Top 10 passwords of 2013, according to Splash Data.


  • 123456
  • Password
  • 12345678
  • qwerty
  • abc123
  • 123456789
  • 111111
  • 1234567

Almost all cameras sold today have a web-based graphical user interface (GUI) and come with a default username and password which is published on the internet.

Some installers don’t change the password at all and leave the same default password for all cameras.

Very  few cameras have a way to disable the GUI, so the security vulnerability is that someone can attempt to hack into the camera via the web GUI to guess a password.

The  hacker must have network access to do this, but the cameras are often on a shared network, not a physically separate network or a VLAN.


Port Forwarding:

Most end users now demand and expect video access from remote mobile devices.

This feature is normally delivered by exposing the DVR, NVR, or VMS to the internet in some way.

This  typical exposure to the internet of an HTTP server is extremely dangerous, as there are a large number of malicious exploits that can be used to obtain access. Machines open to the Internet are typically scanned more than 10,000 times a day.

One example of this vulnerability was the Heart-bleed OpenSSL exploit in 2014; many manufacturers had to ask users to reset their passwords.



As stated above, any on-premise DVR/NVR/VMS should have a firewall for protection, especially if you are going to expose it to the internet for any type of remote access.

Firewalls can be very complex, with thousands of rules. The next generation firewalls are even more complex because they analyse the protocols going over the ports and verify that proper protocols are being used.


Network Topology:

Mixing the cameras on a standard network without separation is a recipe for disaster.

If your security camera system is connected to your main network, you are creating a doorway for hackers to enter your main network via your surveillance system, or to enter your physical security system through your main network.


Operating Systems:

Your on-premise VMS, DVR, NVR or recording system will all have an operating system. The cameras all have an operating system.

All operating systems have vulnerabilities, both Windows-based and Linux-based.

Window OS vulnerabilities are so well-accepted that IT teams monitor them regularly. Recently it has become more and more apparent that Linux has many vulnerabilities also, such as Shell-shock (2014) and Ghost (2015), which made millions of systems vulnerable.

In  theory, your system manufacturer would have a high-quality security team that is responsive in providing you with security updates. The reality is that many vendors don’t do this on a predictable basis.

Cloud-Managed System

Best  practice here is to inquire with your integrator or cloud vendor if the cloud vendor has a dedicated, experienced security team which monitors vulnerabilities.

It also  confirm whether the cloud vendor will automatically send security patches/updates through the cloud to any on-premise appliance. If so, no action is required from the end user to do operating system security monitoring, patching or upgrading.


Data breaches continue to accelerate throughout the world. With increasing Internet connectivity, physical security systems are very vulnerable to cyber-attacks, both as direct attacks and as an entrance to the rest of the network. Liabilities for these attacks are still being defined.

It  is prudent to protect your company and your customers through preventative measures.

To maximize your cyber security, it is critical to define best practices for your own company, as part of your security camera system assessment, as well as its deployment and maintenance.




How to secure your home through CCTV cameras

August 24th, 2019

Many homes and business organisations are investing in a CCTV camera for security. A home CCTV camera is an excellent way to keep your home and its perimeter more secure. You can always have an eye in your place when you are away or seek to deter burglars and other intruders,

They are private way to monitor what is happening in and around your home. Cameras are strategically placed so you can observe certain areas .

The cameras communicate with monitors and the images are shown only to the people who are assigned.

This system is reliable which means it is often used for traffic monitoring , building ,ground security and other important facilities.

Scare off burglars and Intruders:

Having a security camera can be deterrent for burglars and other intruders.

Some of them are bold enough to enter your house when you are at home while other lurk around and wait for you to leave.

Having a security camera is a way to keep them away from your home. If they are bold enough to enter the house, the security cameras can help law enforcement identify the intruders.

Be aware of who is coming to your home:

Some people who visit your home are welcomed , such as the mail carriers or a friendly neighbor.

You might not want to answer the doors for others such as stranger or sales representative.

A home CCTV camera lets you see who is at the door from any room in your house.

Monitor your Children through CCTV:

A CCTV camera can also be the ultimate small monitor. You can watch your children form any room and know what they are doing.

As your children get older , you can see if they are accessing an off limit area such as the supply closet.

When you go to work , you can find out when the children are back home from school.

The camera can also be used as a nanny cam for those who have a babysitter when they are away from home.

Identify disturbances in your place:

At times , you might feel reluctant to approach the source of the noise on your own.

If your something odd, you can check the cameras to find out what is going on before you get there.

If an intruder is present , this could even help to save you from  any danger.

You can also detect suspicious activity around house such as someone scoping out the area.

Buying a CCTV camera for security is an invaluable investment for your home and safety.

Whether your business is a retail outlet or a commercial property, you need to make careful and well thought considerations when it comes to your safety.

You need quality cameras bearing in mind that there are many CCTVs in the market today.

With a quality CCTV system , you are assured of enhanced efficiency as well as increased productivity in your operations.

At the same time, there are many advantages of CCTV installation in your business premises including:

  • Reducing vandalism .
  • Reducing the risk of break INS.
  • Enhanced safety within your business premise.
  • Reduced employee or staff incidents.

You can enhance the quality of your products based on client conversations captured.

You can keep an eye on thieves who steal from shoppers.

Through CCTV camera we can see and check the ongoing process and moreover we can see the previous recording also. In offices CCTV cameras are required to put an eye on employees to check their work dedication and behavior as well.

Quality monitoring of High risk areas:

The use of CCTV in high risks areas comes with extra benefits .

This is common in factories and businesses that deal with dangerous goods and chemicals.

Therefore, if you feel that it is not safe for your personnel to monitor your restricted areas , you can enhance its security using CCTV cameras in such locations .

The cameras help you to monitor the areas in real time.

To benefit from your system , identify accident prone areas to be monitored so that you can enhance the security of your investment as well as that if your employees.

You can protect your clients using CCTV cameras installed in high risk areas.

A point to note is that new customers may not have a better understanding of your premise.

Some may access unauthorized areas unknowingly.

Therefore , with a security system , you can help to protect your employees and customers from accessing high risk areas.

Full proof coverage:

An efficient CCTV system helps to provide full prove coverage to your business premise. In the past , many business would lose a lot of money due to bad vices amongst employees such as giving out unnecessary discounts to their friends and families.

However, a CCTV system offers a reliable security that can be monitored and tracked down through different command systems.

Therefore , you will be able to keep an eye on all operations , vulnerable areas and ensure all activities are carried out as per company regulations .

You can prevent human errors during stocktaking and other unforeseen mistakes that can put the security of your business at risk.

It is equally important to note that even with CCTV cameras in your business, they are culprits that are likely to break in .

In the event of such incidences, your surveillance system increases your chances of capturing culprits and having them face the law.

Many of us are switching on the benefits of CCTV security systems. In the UK it is now estimated that there are more cameras per person than any other country in the world.

Metropolitan Police Commissioner Bernard Hogan Howe promoted the use of CCTV, saying that cameras should be installed by homeowners and businesses to help detectives solve crimes.

The need for residential and business CCTV systems is higher than ever before. With the number of police officers patrolling our streets hitting a record low, total recorded offences are up by 14%, as reported by The Independent in 2018.

The technology is easy to understand, simple to use, and cost effective to maintain. Don’t wait until the worst happens. Thinking ahead now will save you a lot of money and stress in the long run.
