DDNS – Free Dynamic DNS Providers

We maintain the list of Dynamic DNS (DDNS) providers online. Dynamic DNS is a method that allows you to notify a Domain Name Server (DNS) to change in your active DNS configuration on a device such as a router or computer of its configured hostname and address. It is most useful when your computer or network obtains a new IP address lease and you would like to dynamically associate a hostname with that address, without having to manually enter the change every time. Since there are situations where an IP address can change, it helps to have a way of automatically updating hostnames that point to the new address every time. Enter DDNS to the rescue.
We are proud to be considered the top resource online for information on dynamic dns providers. This is a gentle, not-too-technical introduction on it, how it works, and a comprehensive list of mostly free providers. We have also provided some dynamic dns reviews on various hosting companies to help you better decide who to choose!

The Disadvantages of CCTV Cameras

Closed-circuit TV cameras supposed to catch violent thugs have been trained on roads instead - to trap and fine motorists who stray into bus lanes.

The most common home security system used is a CCTV system. CCTV stands for Closed circuit television. It is considered a revolutionary invention when it comes to security. Due to it’s advantages it gained fame in no time. It is often used for security purposes in house, stores and banks etc. It keeps an eye on the visitors. It can also be used in schools to track the behavior of a student. It has countless advantages, but that does not mean that it is perfect. Yes! CCTV has its disadvantages as well. In this article we are going to discuss the disadvantages of CCTV camera.

CCTV is not always a perfect working system for security. It does not keep an eye on every corner of your office, house or mall. It can just keep an eye on a limited area. It can be easily sabotage by sticking a gum or spraying something on the lens or cutting the cables.

Usually a CCTV is installed at a spot where humans can not reach but criminals usually can easily view CCTVs position and can possibly change the angle so the camera do not catches the crime scene. CCTV cameras can view what normal people are doing this effect the people in a bad way as there is no privacy left. This is a great disadvantage of CCTV cameras.

But wireless bullet camera is such a technology that has improved security of malls, houses and offices. In some cases the camera may miss the detail of the crime scene. For example a concealed weapon the camera is unable to view it in the first place.

The video of a CCTV can be hacked by a hacker easily. Suppose there is a CCTV installed near an ATM machine. So the hacker will hack the video of that camera and can easily get the pin code and any other information he wants about a customer or ATM user.

Another disadvantage of CCTV is that not everyone can afford it. Despite all these disadvantages CCTV still allows you to secure your place to a great deal. It has disadvantages but as you know nothing is perfect.

The following are some of the potential weaknesses of IP cameras in comparison to other CCTV cameras.
Disadvantages are that they are costly, do not always work (as they are not set up in the right places) and manipulate with people's privacy.

1. Higher initial cost per camera.

2. Fewer choices of manufacturers.

3. Lack of standards. Different IP cameras may encode video differently or use a different programming interface. This means a particular camera model should be deployed only with compatible IP video recording solutions.

4. Technical barrier. Installation for IP camera required a series of complicated network setting including IP address, DDNS, router setting and port forwarding. This is very difficult for most users to do without help from an IT technician.

5. Lower dynamic range - i.e. reduced ability to cope with low light and high contrast scenes.

HDCCTV has the following disadvantages:

1. Closed technology – little room for improvement in picture quality going forward.

2. Limited maximum resolution of 1.8 mega pixels (1080 TV lines)

3. Currently difficult and expensive to transmit HD images over CAT5e network cables.

4. Dumb cameras – only the DVR is addressable over the network or the web

So here is an article that lets you know about few disadvantages of the CCTV camera. But to me CCTVs advantages are so many that in front of them we can neglect its few disadvantages. Hope the article was helpful. Visit regularly arindamcctvaccesscontrol.blogspot.com Thank You.

Mobile & Remote Video Surveillance Camera Systems

Customers often ask how to access a live view of their remote security cameras when they’re away from their home or business. After all, people lead busy lives, come in and out of work, go on vacations, and run errands so investing in a remote video surveillance system is crucial to the well-being and safety of your home or business. Thus, much of the time you’re not actually able to be onsite where your cameras are installed. One of the primary benefits of IP video is that you’re not limited to viewing your remote video surveillance system on site. The advancements in video surveillance technology have made it possible to view your remote security camera from any internet-enabled PC or smartphone. VideoSurveillance.com has outlined the key components of remote security camera system and video surveillance app, everything you need to know in order to start viewing your security cameras off-site.

What is Remote Video Surveillance?

Remote video surveillance enables users to view live video on a PC or laptop from just about anywhere in the world with internet access. To facilitate remote viewing, you simply type in the IP address of your network security camera in your internet browser like you would a website. This is done through DDNS and port-forwarding, which is discussed in greater detail further below. Once you’ve configured DDNS and port-forwarding and have obtained an IP address to view online, you can then begin to experience what it’s like to view your security camera system from a remote location. Remote security cameras are typically compatible with a wide range of web browsers. It is worth noting that specific web browser support varies by manufacturer.

What is Mobile Monitoring?

Remote mobile video surveillance takes remote monitoring to a whole new level. Several IP camera manufacturers offer complimentary mobile surveillance apps that give you the ability to view and manage your security cameras from a smartphone or tablet such as the iPhone, iPad, or Android. Many of these security camera apps allow you to view multiple cameras simultaneously, control PTZ settings, view recorded images, search through archived footage, play back events, and much more. Just like you would view your security camera(s) on a remote PC/laptop, you will need to have an internet data plan and IP address to do so. Remote video surveillance is perfect for users who are often off-site, and therefore not able to be on the local computer system where their IP cameras are connected.

What’s the Difference between Remote and Mobile Video Surveillance?

The common denominator of remote monitoring and a security camera app is online viewing. The main differences between the two are usability features. Remote monitoring tends to give you greater control over your camera system when it comes to managing settings and recording video. If you’re checking up on your business cameras from your home or hotel on a PC or Mac, you usually have a more reliable and secure internet connection.

A mobile security camera app requires a smartphone data plan, and may lose connection from time to time in no-coverage zones. It’s also a matter of personal preference – if you use the internet primarily on your smartphone, then mobile surveillance may be the right choice for you.

How can Remote Video Surveillance and Mobile Monitoring Help You?

Remote security camera monitoring and mobile surveillance do not require you to be “on location” in order to view and manage each of your security cameras. You’re not limited to monitoring just one camera remotely; most video surveillance apps provide simultaneous viewing and multi-site options so you can check up on all of your remote security cameras in your business or home. Monitoring off-site is also extremely convenient for users as it gives them the freedom to come and go as they please without having to worry about their property. For example, mobile and remote monitoring is great to have when you’re on vacation. If you’ve got two or three IP cameras installed at your home, and decide to take a trip somewhere, you can still monitor your property and receive email notifications if your cameras detect motion or tampering. Essentially, remote video surveillance makes it so you don’t have to be at the exact location of your security cameras to keep a watchful eye on your property. In addition, remote monitoring works wonderfully with pet cams, nanny cams, and pool cams. You’re not limited to what you can view. Surveillance on the go has never been easier.

Features

View Live Stream - Real-time video display is a primary selling point for remote and mobile monitoring. Having direct access to your live camera feed gives you the power to monitor your property without actually being there.

View NVR Live Stream - Some NVR manufacturers offer remote web interfaces and video surveillance apps that provide remote access to your IP camera system. These Internet-based platforms give you instant access to live camera displays and recorded video footage that work on PCs, and some smartphones. You simply log on to the NVR’s web interface or app to facilitate real-time monitoring.

View Recorded Video from your camera/NVR - Another benefit of remote monitoring and mobile surveillance is with some mobile apps and NVR web interfaces, you can view recorded video. This is especially helpful when you’re on vacation; you can review recorded video and decide if it’s relevant or not, or notify law enforcement if you come across something suspicious that was captured on video.

Images are sent to your phone, on motion or schedule - You can configure your IP camera so that images are sent directly to your email account or smartphone via message MMS if motion, tampering, or vandalism is detected. Images can also be sent on a schedule to keep you abreast of what your video monitors.

Send images to email account - With video management software, you can configure your security cameras to send email alerts to your smartphone, iphone or email account for evidentiary purposes and as a way to archive footage deemed important.

Administer VS System remotely - You can do a lot more with mobile and remote monitoring than just viewing live video. A number of IP camera and NVR brands offer web interfaces and cloud services that can be accessed from remote locations. These online platforms allow you to control the settings and configure your IP camera system like you would onsite.

How Do You View Your Video Surveillance Cameras Remotely?

In order to monitor your video surveillance cameras from a remote device like a PC or smartphone, you will typically need to set up DDNS and port forwarding.

DDNS - With video management software, you can configure your security cameras to send email alerts to your smartphone, iphone or email account for evidentiary purposes and as a way to archive footage deemed important.

Port-Forwarding - When you purchase your IP camera system, you’re at first limited to viewing your cameras locally, meaning you can only access them in a local area network. To view your cameras remotely, you must configure port-forwarding. Port-forwarding sends network ports used by your IP camera(s) onto the World Wide Web so that you can monitor your cameras remotely. Network ports are typically forwarded through your network’s router, which tech support specialist at VideoSurveillance.com can help you with. Port-forwarding can only be set up by obtaining the IP address of your router that connects to your video surveillance cameras. It should be noted your IP cameras and NVRs are still secure when accessed via the Internet because of password protection.

Special Plug-and-Play Solutions - Some NVR manufacturers such as Smartvue offer online cloud services that allow you to access your video surveillance system from a remote location by simply logging into your cloud account. Once logged in, you can view your live video feed, manage settings, and search recorded video as needed.

Conclusion

What makes remote video surveillance and mobile monitoring so favorable is that they both fit within your busy schedule. Remote monitoring and mobile surveillance give you on-the-go, real-time access to your live camera view so you can check up on your property anytime, day or night. The remote solutions made available by IP camera, NVR manufacturers, and even third-party mobile app developers are manifold; it is up to you to decide which one best aligns with your day-to-day routine.
