Layer 3 Switch

A Layer 3 switch is essentially a switch that can perform both switching and routing duties. For layer 3 access to remote subnets, a client computer requires a default gateway.

A layer 3 switch combines the operations of a switch and a router into one device. It works as a switch to link devices on the same subnet or virtual LAN at lightning speeds, and it also acts as a router thanks to its IP routing expertise.

Layer 3 Switch comes with 24 Ethernet Ports, But no WAN Interface. It also acts as a switch to connect devices within the same subnet.

Routers

A router is a computer networking device that facilitates the transfer of data packets from one network to another. On the Internet, routers are in charge of traffic directing. Data packets are used to send data over the internet, such as a web page or an email.

It is been used for managing traffic between these networks by forwarding data packets to their intended IP addresses and allowing multiple devices to use the same Internet connection.

Similarities of Layer 3 Switch and routers

At layer 3 of the network, both a layer 3 switch and a layer 3 router operate. Traditional routers and Layer 3 switches have a lot in common. They can both support the same routing protocols, inspect incoming packets, and make dynamic routing decisions based on the source and destination addresses contained within. Routing protocols like RIP, OSPF, and EIGRP can also be configured on the switches.

Difference Between Layer 3 Switch And Routers

Its Cost: When it comes to supplying high-speed inter-VLAN routing, Layer 3 switches are far more cost-effective than routers. Layer 3 switches are often far less expensive than high-performance routers.

Their Port density: Layer 3 switches have a substantially larger port count than routers, which have a lower port density.

Can a Layer 3 switch take the role of a router?

One of the common misconceptions about layer 3 switches vs router is that if a router exists, why do we need layer 3 switches. In reality, they can all be used in a variety of settings and scenarios. Based on the similarities and contrasts we’ve discussed, your options will be determined by your network design and the goals you’re attempting to achieve.

Although it is not suggested to replace a router with a Layer 3 switch, they can be used in the same network. Furthermore, whether a layer 3 switch can replace a router is dependent on the switch model and your expectations. Some layer 3 switches are almost router replacements, featuring WAN, firewall, VoIP, and other features. Those switches, however, are expensive, and most layer 3 switches only have Ethernet ports. A dedicated router is, therefore, more cost-effective than a layer 3 switch in this situation.

A router is a Layer 3 switch that is extensively used. A router, which operates at layer 3, examines the IP and IPX addresses of incoming data packets.

FAQ

What is a Layer 3 switch used for?

A layer 3 switch is a device that combines the functions of a switch and a router into one. It functions as a switch to quickly connect devices on the same subnet or virtual LAN, as well as a router thanks to its IP routing skills.

What is a Layer 3 switch called?

A Layer 3 switch (L3S) is a computer networking device that switches on OSI layer 2 like a regular network switch while also providing additional features on higher OSI layers.

What do routers do?

A router is a type of computer networking device that allows data packets to be transferred from one network to another. Routers are in charge of traffic routing on the Internet. Data packets are used to send data, such as a web page or an email, over the internet.

WiFi Booster VS WiFi Extender: Any differences between them? Let’s find out!…

In today’s modern world, almost everything is available online thanks to advances in technology. A good internet connection is also required, not optional. Different types of networking devices are used to improve network quality. Wifi Extenders and Wifi Boosters are two of the most commonly used networking devices.

People may become puzzled when deciding between a WiFi Booster and a WiFi Extender. WiFi boosters and WiFi extenders are, in fact, the same thing – devices that improve WiFi coverage. Still, there is a bit of difference between devices labeled “boosters” and devices labeled “extenders” by manufacturers.

The difference between Wifi Extender and Wifi Booster is that Wifi Extender works by boosting signal strength to the destination. Wifi Booster, on the other hand, works by eliminating dead spots in order to reach the destination. Other distinctions exist between the two in terms of establishment utilization, purpose, location, and cost.

What is a Wifi Extender?

A WiFi extender is a type of WiFi booster that extends the internet signal from your main router to another location. It communicates with your home network via Ethernet or coaxial cable. It’s essentially the same as adding another router to any WiFi “dead zone” in your home.

Because it uses a wired connection, a WiFi extender does not reduce your bandwidth or become weaker due to thick walls or radio waves, as a WiFi repeater does. You will also save time by not having to sign in to multiple WiFi networks when using an extender.

What is Wifi Booster?

A WiFi booster is a networking device that assists in increasing the connectivity of a wifi network. Wifi boosters are classified into two types: wifi repeaters and wifi extenders. These devices boost the network’s signal. The wifi repeater operates by wirelessly connecting to the network and rebroadcasting it to the original or existing network signal. These serve as antennas.

A new network is established. Network and Network1 are two examples. The network bandwidth is reduced when using a wifi repeater. As a result, the device will be slower. Thick walls, metal, and electronic objects all have an impact on the signal. As a result, it is unsuitable for large homes and offices.

What’s Better: Wireless or Wired Security Cameras?…. The last two years have been turbulent years so far. No doubt that the crime rate has seen an uptick because of swaying economic conditions. 

Once used only in high-end homes and commercial establishments, security cameras have become a common need for everyone today.

Now that we already know we need to buy a good CCTV camera for home but the problem is which one!

Not all security systems are made the same and there are also different options available… but the main debate is whether to buy a wired or wireless security camera!

We understand that there can be a lot of confusion around these two types of security systems, but in the end, it all comes down to your specific wants and needs, anyway we’ve built this guide to help you just in case.

Which is better: Wired or Wireless Security Cameras?

Wired Security Cameras:

Wired security systems, also known as DVR (digital video recorder) security systems, typically have a larger-capacity disk drive than Wireless Security systems. 

The main benefits of installing wired security systems are reliability, defense against hacking, and ease of installation for homes. Not only does that mean your wired system works consistently, but it also means you get fewer false alarms. 

Due to the physical connection between the camera, recorder, and router through cables, you can cover a large area with your system making hardwired security ideal for people living in big houses. 

Talking about the cons, if you don’t already have a system hardwired at your home then getting a wired system installed is a pretty big hassle.

Due to the long wire and connections security cameras are less flexible and cannot be mounted just anywhere. Also, you will have to drill holes in the walls, which can be an issue if the property is rented or on lease.

Portability is another con faced while using wired camera users. Once they are fixed, it’s hard to relocate them. 

Wireless Security Cameras: 

While a burglar can simply cut the wired connection of a security system, it takes a hacker to hack a wireless security system. 

Other major advantages of having wireless security cameras are they are easy to set up and there is no need to open up walls or ceilings for installation.

Where wired cameras use DVR and wire connection, the Wireless cameras use an electrical outlet for power and transmit video signals wirelessly via your home’s Wi-Fi. 

What might turn you away from wireless security is that if the Internet in your place or area goes down, then your wireless security cameras will not function.

Wireless security cameras can also fall prey to drive-by hackers and those who have access to your internet. 

Also, the area covered by a wireless camera depends upon the range and speed of your WiFi network, basically, it is less than that of a wired camera. 

Which Is Best for Your Home?

At today’s date, both wired and wireless, are more sophisticated than ever. You should opt for a wired or wireless option depending solely on your needs and requirements. 

If you are cool with short-range sight and flexibility, then you should go for wireless or wire-free security cameras.

But if your house or apartment area is wide it is best to have wired security cameras installed due to their ability to completely cover the premises.

Which is the Best for Your Office?

The office building must be equipped with sensors to ensure that the security system detects and alerts you if something unsavory occurs (such as a break-in, flood, or power outage). For this, you should go for the wireless CCTV connection.

In the incident of a robbery or break-in, one sensor would be tripped when they breach the building’s perimeter (by opening a door or window), and another sensor would be tripped as they moved around inside the building (tripping the motion sensor).

But if your office is small and not located in a remote place you can go for the wired CCTV system as it will also save a lot of budget when compared to the wireless CCTV system. Security systems differ only slightly in terms of the equipment they provide. Some equipment, like any other product, is more sensitive or advanced than others.

One of the primary distinctions between security companies’ equipment is that some are wired while others are wireless. If it’s wired, the installation process can be a real pain. Drilling into the walls will be required to run wires throughout the office.

Anyway, if you are planning to buy a good home security CCTV camera all you have to do is to go to our website https://gntme.com/. and book one! Our sales representatives are always ready to solve your all queries regarding purchase.

Video surveillance devices appear to be ubiquitous these days. Individuals, companies, institutions, and businesses can use it to monitor, document, and account for what happens on their property even while they are not present.

It used to be that installing a video surveillance system and hitting record on a VCR to record what the cameras saw was standard procedure. If something goes wrong, you can go back and check the video clip to see what happened. In the event that a criminal is apprehended, the video recording may be used to identify and prosecute them.

Today, there is a better way, which is known as Video Surveillance System Monitoring. It goes far beyond a standard surveillance system by allowing trained staff to monitor your cameras in real time, 24 hours a day. This allows you to react quickly to a crisis and have a big impact on the outcome.

1. What is Video Surveillance System?

Surveillance is the act of watching someone or something closely in order to prevent or detect a crime. Video surveillance systems, as a result, are a form of electronic surveillance system that lets you to keep a watch on someone or anything.

A video surveillance system is a collection of one or more video cameras that transmit video and audio data to a central location. The photographs are not broadcast on television and are not available to the general public. They can be watched in real time or sent to a central place for recording and storage.

The most basic components of a video camera surveillance system are cameras to capture images and some sort of recording device or monitoring service; one- and two-way audio speakers are also becoming more popular every day, adding yet another tool to the arsenal of a surveillance system monitoring company’s trained technicians. You’ll just need cameras, possibly speakers, and a recording device or monitoring capabilities, aside from the typical miscellaneous supplies used when installing any form of A/V equipment.

2. What is a CCTV Camera?

Closed-circuit television, or CCTV camera, is a self-contained surveillance system that uses coaxial cabling to transport video recordings from connected cameras to a DVR (Digital Video Recorder).

The system is regarded the most efficient and cost-effective method of video monitoring because it uses classic radio frequency (RF).

3. What types of cameras can make up a Video Surveillance System?

When it comes to video surveillance cameras, there are two basic types to choose from, but there are several different options. Analog and digital surveillance cameras are the two types available.

Analog cameras have lower resolution and require coaxial cable connections to the DVR for each camera, as well as separate wired connections for power. Additionally, the cameras must be placed near the DVR to ensure high-quality footage. Because their field of vision is frequently smaller than that of IP/digital cameras, multiple cameras may be required to cover the same area as a single IP camera. Finally, enlarging an image will cause the recorded footage to distort even more.

These cameras, on the other hand, are less expensive, and they have a wide range of design options to ensure that you can find what you need at a reasonable price. Furthermore, unlike IP/Digital cameras, they will not consume any of your network’s bandwidth.

IP/Digital: Internet Protocol cameras have significantly higher resolution and clarity than analogue cameras. They connect to an NVR using a power over ethernet (PoE) switch and only have one cable connecting to both the NVR and the power supply.

IP cameras do not need to be in close proximity to the NVR to produce high-quality images, and their images can be digitally expanded without losing quality. Finally, IP cameras provide a larger field of view as well as a variety of additional features such as motion-activated auto-recording, object recognition, and smart-technology options.

IP cameras do not need to be in close proximity to the NVR to produce high-quality images, and their images can be digitally expanded without losing quality. Finally, IP cameras provide a larger field of view as well as a variety of additional features such as motion-activated auto-recording, object recognition, and smart-technology options.

Digital IP cameras have the disadvantages of being significantly more expensive, requiring more bandwidth from your network to transmit images, and requiring more storage. Furthermore, while Wi-Fi cameras provide the convenience of being able to access their feed from anywhere, they are also hackable, so special attention to their security features is required.

4. How does Video Surveillance Work?

A video surveillance system’s footage can be monitored in a variety of ways.

The most traditional and familiar option is to have a security guard or team responsible for viewing live footage on monitors/display devices connected to the recorder. Analog system displays that use coaxial cables to connect cameras to DVRs and display units are typically monochrome, but they can also be HD with colour.

However, because the vast majority of today’s security cameras are digital internet protocol cameras, the feed is now accessible through one’s network. While it is still viewable on an official display unit, computers and mobile devices can also access it. Furthermore, certain systems and cameras can detect movement before sending mobile notifications to authorised workers who can then view the live feed.

5. What’s the difference between CCTV camera and surveillance camera?

The CCTV system collects video feeds from all connected cameras and sends them to receiving equipment such as a monitor. This connection is typically made using a coaxial cable. The closed-circuit system that is used to monitor and control a specific property is made up of an entire network of surveillance cameras. These cameras are frequently connected to IP (internet protocol) networks, which connect security (surveillance) cameras in remote locations to the main location.

CCTV cameras are used to manage the security of public and industrial facilities. These systems can be combined with intrusion detection devices to provide enhanced security. While a security or surveillance camera is better used for simply monitoring a specific area and thus controlling any undesirable situation.

Periodic Inspection and Cleaning

To reduce the harmful impact of environmental dust or debris, we recommend inspecting and cleaning the router’s external surface on a regular basis. The frequency of examination and cleaning is determined by the severity of the environmental conditions, but we propose once every six months at the very least. Vacuuming the router’s air intake and exhaust vents is part of the cleaning process.

Note: Sites with persistently high ambient temperatures and potentially significant amounts of dust or debris may necessitate frequent preventative maintenance cleaning.

AI Security CCTV Cameras are specialised network IP cameras that can detect vehicles, persons, and faces, as well as perform advanced analytical activities such as traffic counts, people counting, and licence plate identification (LPR). These artificial intelligence activities are accomplished through the use of highly complex video analytics software that is built into the camera and recorder to which they are linked. Viewtron AI cameras can be utilised as standalone devices by recording to an SD card, or they can be linked to a Viewtron network video recorder (NVR) to form a multi-camera AI system that records to a central hard drive. Please keep in mind that licence plate identification / automatic number plate recognition is only available on specific models (ANPR).

Have you ever heard about Artificial Intelligence or AI Security CCTV Cameras? Well, CCTV surveillance cameras are typically viewed as digital eyes. But what happens if these digital eyes get the brains to match?

Though, traditional CCTV’s act as a deterrence, they’re more like portholes: useful only when someone is looking through them. For example, when someone stoles your car. You have to go through tons of video clips just to make sure the person how has stolen it.

The difficulty with most CCTV cameras used for surveillance is that they are not ‘intelligent.’ It simply gives a recorded or a live feed of the surroundings, which is only useful when conducting a post-mortem on an incident or keeping a watch on what is going on.

Furthermore, the quantity of labor required to monitor each and every one of these cameras would be enormous: enters Artificial Intelligence AI Security CCTV Cameras.

Though we haven’t reached Blade Runner levels of artificial intelligence, we are on our way to some interesting features with AI security camera software.

Person detection and intelligent alarms that only warn when the camera recognizes people rather than animals, cars, or other inanimate moving objects are just a few of the advanced capabilities that artificial intelligence in security and surveillance provides.

Artificial intelligence is providing security cameras with digital brains to match their eyes, allowing them to analyze live video without the need for people. This might be good news for public safety, allowing police and first responders to notice crimes and accidents more readily, as well as having a variety of scientific and industrial applications.

Secondly, AI will be able to identify serial offenders and their vehicles, possibly even alerting workers to their presence on-site before they reach a business’s premises.
Assume there was a robbery and you have no idea what happened. However, there was a Jeep Wrangler heading east after that. So we go in and look for a Jeep Wrangler, and there it is. The first significant benefit of merging AI with CCTV will be this. Without this technology, you’d only have your camera to work with, and you’d have to filter through hours and hours and hours of video.

AI CCTV camera runs on Google Cloud and can search footage from pretty much any CCTV system. Maybe the users will have to pay a monthly fee for access, starting approx around $7, and to scale up with the number of cameras.

The incorporation of AI into systems will effectively transform an industry where prior innovation has been focused on the quality of video captured and the integration of being able to handle security, lighting, and heating remotely through a single provider in recent years.

Finally, the integration of AI Security CCTV Cameras will undoubtedly help the market to further prove its worth and place in 2022 and beyond, so the industry needs these developments to continue at the rate we’ve seen in recent years.

It’s natural to be concerned about new technology falling into the hands of the wrong people. That is true for any technology… However, we believe that the benefits exceed the drawbacks in the case of artificial intelligence in security and surveillance.

AI Security Camera FAQ

What is an AI security camera? –

AI security cameras detect things and distinguish detailed attributes using artificial intelligence software. Vehicle detection, human detection, facial recognition, and licence plate identification are all examples of object detection that can be used to trigger events on Viewtron NVRs. For example, when a person enters a specific zone within a surveillance area, the DVR can begin recording. An alarm, such as a push notice to the Viewtron mobile app, can also be triggered.

Can Viewtron AI cameras be used in conjunction with hybrid DVRs? –

No, it does not. Despite the fact that all Viewtron IP cameras are compatible with our Viewtron hybrid BNC DVRs, the AI software is only available on the NVRs.

Are AI cameras with 4K resolution available? –

At the moment, Viewtron AI cameras have a maximum resolution of 4mp.

Is the persons detecting system effective with children and toddlers?

Yes. The person detection mechanism detects both little and large individuals.

Can you record only when alarm events occur instead of continuously recording video?

Yes, you can configure recording to occur only when certain events occur, such as object detection. Alternatively, you can record at a lesser quality and frame rate 24/7 and at a greater resolution and frame rate for AI-triggered alert events such as persons detection.

Is there a recurring subscription or software licencing fee?

No, there are no maintenance or software licence fees.

Is it possible to access camera data outside of the local network (LAN)?

Viewing your cameras remotely is entirely optional. It is entirely up to you whether or not to permit remote access from mobile apps for PC software. If you do, you’ll need a login name and password to go in.

Is there any reliance on external servers or cloud services for AI functions?

No. Viewtron security systems are self-contained. On the IP cameras and NVR, all of the software is installed. Neither of those requires an Internet connection.

Is it possible to utilise AI cameras on all NVR channels?

Yes. AI cameras are supported on all channels by our 8ch, 16ch, and 32ch NVRs.

Is it possible to receive a push notification on my phone when an alarm is triggered?

Yes. All AI events offered by Viewtron AI cameras can be used to send a push notification to the Android and iPhone mobile apps. Watch this video to see how a person detection alarm causes a push notice to be sent.

Is it possible for a single AI camera to execute more than one type of AI function at the same time?

No. Each AI camera is only capable of doing one type of AI function. For example, one camera CANNOT be configured to detect facial recognition and vehicle detection at the same time.
