The maximum distance supported by the CCTV Balun is 2,200 feet in a point-to-point connection. Based on a typical DC loop resistance of 19.2 Ω/100m (58.5 Ω/1000ft), this translates into a DC loop resistance of 128 Ω. To determine whether the link is within specification, short the twisted pair at one end of the link and measure the DC loop resistance with an ohmmeter. The following table provides some data
CCTV Cable Measuring Length
If additional coaxial cable is connected between the CCTV equipment and the Balun, it is considered part of the total distance specification. Furthermore, there is no maximum cable length for the amount of coaxial cable that may be added, as long as the total distance between the CCTV camera and the CCTV receiver (DVR) is within the
Maximum specified distance on the SS Computers datasheet
If you’re installing security cameras yourself, it’s easiest to buy wireless cameras. Since there are no wires or cables to worry about, it’s a snap. Also, with most wireless cameras, you can remotely view footage from a smartphone or other internet connection. With that in mind, here are some common places where people put security cameras in their home:
Back and front door
Many people put cameras at their front door, but then they neglect the back door. According to famous jewel thief Walter T. Shaw, burglars will often favor breaking into the back door rather than the front. Shaw says that, “The No. 1 way into a home is through the French doors or sliding doors in the back.” So, he is puzzled when he sees homes that only guard the front door with security cameras.
Areas of high foot traffic
Inside your home, you’ll want to place cameras in areas of high foot traffic, places where an intruder would have to walk through to access other parts of the house, such as hallways, entryways, and living areas.
Bedrooms
Burglars often ransack master bedrooms first, so it’s a good idea to put at least one camera in there. Additionally, if you want to use cameras to keep an eye on your kids or an infant, put cameras in the kids’ rooms. Imagine being able to cook dinner, work at your desk, or watch TV in another room, while being able to easily check on your sleeping baby or children from your smartphone.
Make sure to place your cameras at the most effective angle. Cameras with motion sensors will better detect motion when an intruder walks past it and not directly toward it. That’s why hallways and entry points are great places to put cameras.
Security cameras should be placed in areas where there’s enough light to get a good, focused shot. Although, night vision cameras can help you see footage in dark areas they’re usually grainy or difficult to see.
You may not think you need security cameras when you’re at home, but you’d be surprised how useful they can be.
See who is at the front door from any room in your house. This is especially convenient in the middle of the night or when you’re not on the first floor.)
Use it as a video baby monitor.
Know what’s going on with all family members throughout the house, and monitor areas that are off-limits, like the workshop or cleaning supply closet.
Care more easily for an elderly family member by setting up a camera in the area where they spend the most time. You can keep an eye on them from another room, or while you’re away from home.
Identify the creepy noise coming from downstairs, without even getting out of bed. If you hear suspicious noises in your home, especially at odd hours, check the cameras to see what is happening before going directly to the source of the noise.
Security cameras aren’t just for catching burglars in the act— they can give you peace of mind when it comes to your family, your kids, and your property by letting you see what’s going on at all times.
Catch a burglar or intruder on tape while they try to break in.
Check on the pets while you’re away.
Know when the kids come home from school.
See what’s going on if your alarm sounds and you’re out; then determine whether it’s a false alarm or something more serious.
Keep an eye on the nanny or babysitter while you’re away.
Watch for any suspicious behavior around your house. This may include strangers that have been lingering or scoping out your home.
Check on the maintenance crew or anyone working on or around the home when you’re not there.
Blue screens are caused by hardware Problems and Issues with low-level software running in the Windows kernel. A blue screen occurs when Windows encounters a “STOP Error.” This critical failure causes Windows to crash and stop working. The only thing Windows can do is stop the computer and restart it.
Windows NT, 2000, XP, Vista, and later versions of Windows have a blue screen error that is similar to the example shown below. These error messages often contain more detailed information and will contain information that can be searched for and found. If you’re not getting a blue screen error that looks like the example below, skip to the next Fatal exception section.
Note:If you are getting a solid blue screen with no white text, you are not encountering a BSoD. It’s likely a problem with your video card, monitor, or other hardware. Follow the no display on monitor troubleshooting steps to diagnose this problem.
Blue Screen Errors on Windows
1.Identify the blue screen by locating a line containing all capital letters with underscores instead of spaces, such as the above example, BAD_POOL_HEADER. Write this information down. If you do not see anything written in all caps with underscores like this, skip this step.
2.Get either the STOP: error message at the top of the error, or in the “Technical Information:” portion of the error. For example, in the above error, it is STOP: 0x00000019 … write the first portion of this error message down.
3.Finally, if technical information is shown, write down the file and the address.
Fixing Blue Screen Issue
Determine if you changed anything recently.
Blue Screen Errors on Windows
The most common cause of the Blue Screen is a recent change in your computer’s settings or hardware. This is often related to new drivers getting installed or updated. Drivers are software that allow your hardware to communicate with Windows. If you have a restore point, try to load it and see if it helps, it may or may not. Because there are essentially an infinite number of hardware configurations possible, drivers can’t be tested for every possible setup. This means that sometimes a driver will be installed that causes a critical error when communicating with the hardware. If not resolved Contact your nearest Laptop / Desktop Service Centre.
Check your computer’s internal hardware.
Blue Screen Errors on Windows
Sometimes, a poor connection inside the computer can cause a Blue Screen. Open your case and check to make sure that all the cables are firmly connected and that any cards are seated firmly in their sockets. This is more difficult for laptops in those situation Contact your nearest Laptop Service Centre (or) you can check the hard drive and the RAM to make sure that they are connected properly. Remove the panels in the back that cover the hard drive and RAM with a small Phillips-head screwdriver. Press the components firmly into their connections.
Overheating can lead to your hardware malfunctioning.
One of the most common components to overheat is the Graphics Card either Purchase a New Graphic Card at your nearest Desktop Service Centre. The second most likely culprit is the CPU. You can check temperatures in most BIOS menus, or through software in Windows.
Test your RAM.
Blue Screen Errors on Windows
A common culprit in system crashes is a bad stick of RAM check with your Local Laptop / Desktop Service centre for a Better RAM. When RAM fails, it causes the system to become unstable. You can test your RAM by using a program called “memtest86”. To run the Software and to avoid Risk Contact Desktop Service Centre. Memtest will run indefinitely until you stop it yourself.
Test your hard drive.
Blue Screen Errors on Windows
Run the “chkdsk” function on your hard drive to scan for errors and fix potential problems. A failing hard drive can cause Blue Screens due to corrupted files. To run chkdsk, open Computer/My Computer and right-click the disk that you want to scan. Select Properties. From the Properties screen, select the Tools tab. Click Check Now in the Error Checking section. Your computer will prompt you to restart in order to scan the disk. Still facing the same issue Check with your Local Computer Service centre.
Strip your computer down to the essentials.
One way to narrow down what is causing the problem is to remove everything that is not essential for the PC to run. This way, if the error goes away, you know that it was one of the pieces that you disconnected.
Blue Screen Errors on Windows
A desktop computer needs the Motherboard, CPU, a Hard Disk, Power Supply, RAM, and a Keyboard. Plug your monitor into your motherboard’s monitor port (if it has one) so that you can disconnect the Graphics Card. Everything else can be removed during the diagnostic process.
If the computer runs fine after stripping it down, add one part back at a time until the error message appears again. This will let you know which device is causing the computer to crash. This method does not apply to laptops, as you cannot strip it down so you can speak with your Local Laptop Service Centre.
The first thing people do after installing an operating system is to install an antivirus software. With an antivirus installed, they think that their computer is safe now. But how effective are these antivirus? New malware is written every day while old ones are enhanced to bypass both signature and behavior based anti malware. Under current circumstances, it is safe to say that antivirus software itself can be exploited by the cyber criminals to compromise your computer.
Let us have some of the Major question that may help.
Do Antivirus really work?
According to Google Zero Day Blog, a security researcher found many vulnerabilities in the many antivirus suite, that allowed malware to get into the base and exploit the operating systems those antivirus software can tweak the OS and browsers, they can easily be targeted to compromise the computer.
Virus Detected
The blog also cites examples of compressed applications. When developers want to reduce the footprint of their applications, they compress the applications and hence, are not easily identified by antivirus. To solve this, anti-malware from few antivirus unpacks the application straight in the Kernel – instead of using sand boxing techniques. You can imagine what may happen while unpacking an infected application in the base of the operating system.
As far as from those antiviruses concerned, it released few updates and says the issues pointed out by Google are solved for now. But those are not the only one. There are many other anti malware packages and more zero-day vulnerabilities to be explored and patched.
Reading this, one might feel that using a basic antivirus software is better as it not only saves on resources but also doesn’t go on to integrate themselves with the operating system files.
Is an Antivirus still good enough to protect you?
Antivirus software is either offered as free basic version or a paid pro version with some additional features. The same holds true for Internet Security Suites too.
Virus Tags
Out of these two, the paid one’s typically are bulkier, occupy more space, take up RAM and use more CPU, etc., while at the same time offering you integrated protection.
The problem starts at the point where the advanced anti-malware start interfering with your operating system and browsers. These security software reach out to the OS kernel and tweak it for continuous monitoring. They also bypass the built in features of browsers that detect dangerous web pages. That means installing such a security software can expose you more to the dangers lurking out there on the Internet.
Do you need an antivirus?
Yes, sure you need an antivirus software not just for your Windows computer, but even for your Mac or Linux systems, these days. While it is good to use a modern operating system like Windows 10, Windows 8.1 or Windows 7 to protect your computer against online threats, a security software offers an additional layer of protection against malware. It will help you stop almost all known malware and even detect unknown one’s
Most malware today, get on systems, due to user-initiated actions. It could be a user clicking on a bad link, visiting a malicious website, not paying attention during installation, opening infected attachments and so on. And so, in today’s times, to stay safe online not only do you need to secure your Windows PC, you need to also exercise common sense and follow these basic Internet security tips:
Always keep your operating system antivirus software and browsers updated to the latestantivirus-plus-firewall
versions
Do not download email attachments from unknown senders, which you were not expecting or which look suspicious
Do not click on any link blindly- whether it is in an email or a web page.
If you must download software, download it only for their official home pages or from safe software download sites and exercise caution while you install them.
Install additional free tools like EMET to add an additional layer of security.
So is your Antivirus still good enough to protect you from modern online threats? Well – it is good, but not enough!
