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.

What is Difference between Switches and Routers?
What is Difference between Switches and Routers?: Right in front of us, we have an image of two boxes that look very similar. They both have lights on the front and network ports on the back. So… how do you tell the difference between these two boxes? Well though they look similar, these two devices perform different functions within a network. Both the router and the switch are network-connecting devices. The router, on the other hand, operates at the network layer and is responsible for determining the quickest path for a packet, whereas the switch connects various devices in a network. So basically we can say that switches create networks while routers connect networks. To understand the difference between Router and Switch, let us have a close look to understand these two devices.
What is Difference between Switches and Routers?
Difference Chart between Switch and Router
Switch | Router |
---|---|
It connects a number of networked devices in the network. | It connects many switches and their associated networks. |
It operates on the OSI model’s data link layer. | It operates at the OSI model’s network layer. |
It is used on a LAN. | It can be utilised in LAN or MAN networks. |
A switch is incapable of doing NAT or Network Address Translation. | A router is capable of doing Network Address Translation. |
When making complex routing considerations, the changeover takes longer. | A router can make routing decisions significantly more quickly than a switch. |
It only provides port security. | It includes security procedures to keep the network safe from security threats. |
It is classified as a semi-intelligent device. | It is referred to as an Intelligent network device. |
It may transmit data in either half-duplex or full-duplex mode. | It transmits data in full-duplex mode. We may, however, alter it manually to work in half-duplex mode. |
It transmits data from one device to another in the form of frames (for L2 switches) and packets (for L3 switch). | It uses data packets to convey information from one network to another. |
Switches can only connect to wired networks. | Routers can communicate with both wired and wireless networks. |
Switches come in a variety of port configurations, including 8, 16, 24, 48, and 64. | By default, a router has two ports, such as a Fast Ethernet Port. However, we can specifically add the serial ports. |
For the source and destination MAC addresses, it consults the CAM (Content Addressable Memory) table. | It consults the routing database to determine the optimum route for the destination IP address. |
What is a Switch?
A switch is a type of computer networking equipment that connects multiple devices on a single computer network. Switches provide the sharing of resources by linking together all the devices, including computers, printers, servers, etc., in a small business network. Switches are commonly referred to as bridging devices because the process of connecting networks is also known as bridging.
How does a switch work?
Multiple data cables are connected to a switch to allow communication between networked devices. Switches use MAC addresses to forward their messages. To receive, process, and forward data at the data link layer, the operating system employs packet switching. Switches simply retransmit packets out of every port of the hub except the port on which the packet was received, unable to distinguish different recipients, and achieving overall lower network efficiency. Unlike routers, switches are restricted to wired network connections. Switch stores the MAC address in a lookup table and end the message directly to the right devices.
What is a Router?
Routers are more sophisticated devices than switches. A router joins many switches and their separate networks to make an even larger network, just as a switch connects multiple devices to form a network. So basically a router works as a dispatcher, directing traffic and choosing the most efficient route for information.
How does a Router work?
Routers are devices that connect computers and other devices to the Internet. A router connects network devices by passing data packets between them. This information can be transmitted between devices or from devices to the internet. The router accomplishes this by allocating a local IP address to each device on the network. This guarantees that data packets are sent to the correct location rather than being lost within the network. Furthermore, many routers include built-in switches that enable you to connect several wired devices.
Hope you have understood the basic difference between Switches and Routers. For more information on the electronic world visit our website now.
Conclusion
According to the explanation above, we can say that both are crucial devices for establishing a network and have their unique relevance in the network. However, in order to set up a home network and connect devices, we require a switch, and in order to link two networks, we require a router.
FAQ
Do I need a router if I have a switch?
Switches have no routing capabilities and cannot function in place of a router. Your router most certainly includes a four-port switch built in, but that doesn’t mean your new eight-port dedicated switch can replace it—the router is still required to act as a bridge between your modem and switch.
What comes first switch or router?
In a typical home arrangement, the switch should be placed after the router. since the modem will only communicate with the first computer that connects to it A router is required to share the connection. As a result, the “initial device” is frequently a router.
Why is a router better than a switch?
While a network switch can link multiple devices and networks to increase the LAN, a router allows multiple network devices to share a single IP address. The router will enable PCs and other network-connected devices to connect to the internet and other networks.
Can I put my router after a switch?
In a summary, it is not possible to connect a modem to a router. Not practically, at any rate. Each port on the switch has its own IP address. From the outside, it appears that you have placed a managed switch before the router, but this still adheres to the premise that the router comes before the network switch.
How many switches can connect to a router?
The number of network switches that can be connected to a router is theoretically unlimited. Daisy-chaining allows you to link as many switches as you like together; however, this is not suggested because it increases the chance of producing a loop if they are not connected correctly.
AI Security CCTV Cameras: Future of Video Surveillance Security
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.
