What is CCTV?
Closed Circuit Television (CCTV) is a system where the circuit in which the video is transmitted is closed and all the elements (camera, display monitors, recording devices) are directly connected. This is unlike broadcast television where any receiver that is correctly tuned can pick up and display or store the signal. Such specialized systems are not subject to regulation by the Federal Communications Commission (FCC); however, security cameras using scrambled radio waves are in fact subject to common carrier tariffs and FCC conditions of service. In the past, these signals would be transmitted to a monitor equipped with a videocassette recorder, but these have been all but totally replaced by digital video recorder (DVR) systems that can store far more video and back up data automatically.
What is CCTV Used For?
The most common use of CCTV is in security camera systems. They’ve been found for years in areas like large retail shops, banks, and government institutions. Thanks to reduced costs in the manufacture of cameras and video recording equipment, camera systems are becoming more and more commonplace in smaller businesses, and even private homes.
Other Uses of CCTV
CCTV has become ubiquitous in large cities, along major highways, and areas that host large events. On streets and roads, CCTV is often used in traffic law enforcement, but it’s used to monitor traffic patterns, allowing emergency services to react quickly to accidents and for maintenance departments to better plan necessary construction projects. In hotels, stadiums, and convention centers, CCTV is often used in private television networks, broadcasting sporting events or special events throughout their facilities.
Most airports and train stations throughout the world have installed security cameras connected to CCTV systems with the goal of combating terrorism. These video feeds are constantly monitored by local and international law enforcement agencies in an effort to keep travellers safe.
CCTV Cameras
Any camera that broadcasts a signal can be attached to a CCTV system, whether it’s wired or wireless, but they are most often associated with high-end surveillance cameras. Pan/tilt/zoom (PTZ) cameras allow a user to remotely control a camera. The type of lens used will depend on the application and area the camera will be installed
How to use Edge Browser with IE mode for Hikvision devices
in Hikvision
It’s possible to use the Microsoft Edge browser to access your Hikvision cameras or NVR/DVR. Then you can see the live view, playback mode, download footage and adjust other settings.
This guide shows how to use the Microsoft Edge browser to view Hikvision cameras, NVR, and DVR. The trick is to enable the built-in Internet Explorer mode.
As you may know, Internet Explorer has been serving the tech community for 25 years and Microsoft is finally ending its support. The end-of-support date will be June 15, 2022.
After the Windows 10 update 21H2, the Internet Explorer browser will be hidden/removed from the OS. Once they do that, you need to use other browsers to access the CCTV systems.
The instructions shown here are valid for Hikvision devices, logo, or OEM versions. Actually, the same settings are applicable to their surveillance manufacturer.
If the Internet Explorer is gone, try to use this method to see the camera via the Edge browser. In this example, we use the instructions presented by LTS (which is a Hikvision OEM reseller).
The basic requirements:
-
Run the latest Windows Update. The Edge browser version should be up to date. The minimal version is 91.0.86, anything older won’t work.
-
Make sure the Edge Browser is not restricted by the business or the organization. Otherwise, some functions will not be available.
How to view security cameras via the Microsoft Edge browser
Step 1. Set the Edge browser as the default one. Open the Edge Browser from the Windows 10 PC first, then go to the three dots icon (…) and select Settings from the menu.
Go to the Default Browser section. Turn on Allow sites to be reloaded in Internet Explorer mode. This requires restarting the Edge Browser to take effect.
Note: If you do not see this function, that either means this Edge browser is not supported by this function or the Internet Explorer browser has not been restricted from the Windows10 system yet. You should still be able to find Internet Explorer 11 from Windows Search.
Step 2. After you restart the Edge browser and go to the NVR/DVR Login page, nothing will appear different on the screen. This is because you need to Reload in Internet Explorer Mode from the Menu.
Go to the three dots (…) button, then Tools, and click on Reload in Internet Explorer mode.
Step 3. After the browser reloads again, you’ve entered the Internet Explorer mode. The most noticeable difference is the prompt message at the top of the page. Note: Do not click Leave.
Edge will revert back to regular Edge mode. If you accidentally click Leave, you need to go again through the steps and reload the Internet Explorer Mode from the Menu.
Step 4. For the next step, type the IP address of the NVR/DVR or camera and enter your username/password. Then you should see the “please download plug-in” message on the center of the screen.
This is the plugin that allows the camera to function normally via the web browser. Download the plug-in and install it. After fully loading, Refresh the page, and click Allow.
Then, you should be able to see the video after clicking the Play All button.
Basically, that’s all, everything should be exactly the same as Internet Explorer. You should be able to view the camera streams without any issue, playback, adjust settings, etc.
How to download video files from the Edge Browser IE Mode?
