Teacher Vulnerability- The Call for Surveillance in Schools

5246453478_64a4070c71_b

Research in The Guardian suggests that one in five school staff fall victim to false claims. Now more than ever, teachers feel vulnerable in the classroom, resulting in some leaving the profession entirely.

These are not unique or isolated incidents. In a recent survey undertaken by the Association of Teachers and Lecturers, it was found that over a third of the 695 people polled stated that someone in their current school or college had had false allegations made against them.

These statistics got us thinking. Surely, the answer lies in physical security? CCTV would act as a safety measure to give validity to any accusations, whilst also providing bolstered safety and security. This was proven in the case of Helsby High School, a state maintained secondary school that suffered with issues relating to safety and security, in response to the issues the school turned to D-Link’s range of surveillance solutions. This has resulted in a vast improvement across the school in terms of positive behavioral change as witnessed by the staff at Helsby.

Ultimately it comes down to the benefits physical security has to offer the education system. CCTV would provide a watchful eye and a safety layer in place that would give validity to sensitive issues such as teacher vulnerability, more schools need to follow in the footsteps of Helsby High School and put a security layer in place.

Wi-Fi Camera Buying Guide

Wi-fi-cameras-buying-guide1

If you can’t be physically present to keep an eye on your home, business or vacation property, the next best thing is a state-of-the-art digital camera that can stream real-time video to the networked device of your choice.

Unlike typical security cameras, network cameras, Cloud Cameras, or Wi-Fi Cameras don’t require a closed circuit TV system and special cabling to work. Instead, they connect to your home’s existing network via Ethernet or Wi-Fi, just like a laptop or tablet. Once connected, they stream live video you can access from any connected computer. The most flexible systems even let you view feeds through a web browser, smartphone or tablet; great for on-the-go viewing.

Wi-Fi cameras are the perfect solution for homeowners, business owners, pet owners, parents and anyone with something to watch. To help you sort through the choices, this guide offers some quick recommendations and plenty of info about key features to look for in your next camera.

Wi-Fi cameras for every need
The average home user needs reliable monitoring that doesn’t cost an arm and a leg, whereas a business owner might be interested in greater functionality and integration with existing security systems. Network cameras fall into two classes corresponding to these types of users.

Entry Level Cameras PetCam_DCS933L

These cameras are small, very affordable and perfect for the home user. Designed to be easy to set up and easy to use, they connect to a wireless home network at the push of a button. Key features include:

  • Wireless capability and compact size for flexibility of placement
  • Low cost so you can purchase enough cameras to cover multiple areas
  • Ability to check camera feeds from any web browser, iPhone®, Android® device or tablet

Professional Level Cameras DCS-6112

These cameras are more expensive than entry-level cameras. However, the added investment pays off in upgraded features that make it possible to integrate your cameras with dedicated alarm and sensor systems. Key features include:

  • Designed for permanent installation, with durable, rugged housing
  • Wired or wireless connectivity
  • Outputs for alarm and access control systems

This guide will focus on entry level network cameras, as they offer plenty of functionality for the average household. If you need more robust features, visit the network camera page on dlink.com to learn more.

Features to look for
Not all cameras work the same way or offer the same capabilities. In this section, we’ll look at the most important features and what they mean to you.

Web Access

Some cameras require software to access a camera’s output and only computers that have this software installed can view the feed. Other cameras, like D-Link Cloud Cameras, offer more flexibility and are viewable using a web browser so you can check your cameras locally or remotely from any connected computer.

Recommended Models: DCS-933L, DCS-2132L, DCS-2330L, DCS-5020L

Wi-Fi Connectivity

Some cameras support wireless, or Wi-Fi, while others require a wired connection of some kind. Wireless cameras give you the flexibility to keep an eye on areas that would be too hard to reach with a wired model. However, a wired connection may be more reliable depending on the building’s construction and the router’s location. So, what’s the better option? Both. D-Link Cloud Cameras are wireless-ready and offer a wired Ethernet option, giving you the best of both worlds.

Mobile Apps android_phone_mydlink_web

For truly mobile viewing, you need a camera that allows you to see a live feed from your smartphone or tablet. D-Link’s mobile interface is a free app called mydlink™ Lite and is available for both iPhone and Android devices. The app works with all mydlink-enabled cameras and is completely free to use. With mydlink Lite, you can view your home or office and keep an eye on your kids, pets and possessions from anywhere with a Wi-Fi, 3G or 4G connection.

Recommended Models: DCS-933L, DCS-2132L, DCS-2330L, DCS-5020L
Motion Sensing

If you choose to record footage only when motion is detected, you’ll save disk space and know exactly what footage you need to view. If you plan to record footage, select a camera that makes it easy to set motion triggers as well as specify recording schedules so you can record exactly what you want directly to your PC.

Recommended Models: DCS-933L, DCS-942L, DCS-2132L, DCS-2332L, DCS-5010L, DCS-5020L

Enhanced Motion Detection

For more reliable motion detection day and night, certain cameras feature passive infrared (PIR) sensors that use changes in heat to detect movement, rather than visual cues. This is great for monitoring at night when a standard camera would not be able to detect motion due to low light conditions.

Recommended Models: DCS-942L, DCS-2132L, DCS-2332L

Night Vision day_night_web

Some network cameras can illuminate a low-light or no-light area with infrared lighting so you can clearly see what is happening day or night. Infrared lighting is invisible to the human eye but allows the camera a clear view, even in total darkness.

Recommended Models: DCS-932L, DCS-933L, DCS-942L, DCS-2132L, DCS-2330L, DCS-2332L, DCS-5010L, DCS-5020L, DCS-5222L

IR-cut Filter for Best Color Quality

For the best color representation during the daytime, choose a camera with an infrared cut-off filter, or an IR-cut filter. Network cameras see much more of the color spectrum than the human eye, particularly near the infrared region, which can often result in strange or skewed color representation. IR-cut filters work by blocking this infrared light so the colors appear more realistic.

Sound Detection

For those looking to keep an eye on their loved ones or their homes while on vacation, sound detection is the perfect addition to the standard motion detection feature. With automatic email alerts and the ability to configure sound detection for a specific area, cameras with this feature allow you to stay one step ahead.

D-Link Camera Models: DCS-931L, DCS-933L, DCS-5020L

Built-In Wireless Extender

To ensure that you are able to place your camera wherever you need to without going outside of your wireless network range, choose a camera that comes with a built-in Wi-Fi extender. Simply place your camera anywhere within your signal range to instantly increase your wireless home coverage and easily add additional cameras to your network.

Wi-Fi Router

Wi-Fi-routers-buying-guide-copyWi-Fi Router Buying Guide
A router is the hub of your network. The wizard behind the curtain, ensuring that your computers, tablets, smartphones, gaming consoles and SmartTVs can connect to each other and to the Internet without a hitch. When it comes to routers, there are many options to choose from with countless differentiating features. While helpful, this can make finding the best model for your specific needs a headache.

To help you sort through the choices, this guide offers some quick recommendations and plenty of info about key features to look for in your next router.

The two most important features
D-Link Wireless AC1000 Dual Band Gigabit Cloud Router (DIR-820L)While it’s still possible to purchase a wired router, the type that require you to physically plug in your devices with an Ethernet cable, Wi-Fi (wireless) models are the most flexible tools for connecting devices in today’s increasingly wireless world.

DIR820L

Here’s some quick info on the top two features that matter most when it comes to wireless routers: wireless range and wireless speed.

Wireless Range

A router’s Wi-Fi range depends on many factors – how many radios and antennas it has, what frequencies it broadcasts on, interference – the list goes on. All you really need to know, though, is Wireless AC routers provide the best connectivity at the farthest range, followed by Wireless N routers. If you want reliable Wi-Fi throughout your house, stick to AC and steer clear of Wireless G.

Wireless Speed

Wireless speeds have come a long way since Wi-Fi routers first hit the market. Wireless AC routers are 3x faster than Wireless N and Wireless N routers are 14x faster than Wireless G. Moral of the story? If you use real-time applications, like gaming or streaming video, Wireless AC will offer a superior experience to N or G.

Different Levels of Wi-Fi at a glance

Dual Band Technology

When shopping for a router, you’ll find both single band and dual band models. Single band routers operate on one wireless frequency only, the 2.4GHz band. While it works well for surfing the Internet, this frequency can get overly congested making it unsuitable for high-bandwidth apps like streaming video. Dual band routers transmit data over the 2.4GHz band and the 5GHz band, which is less prone to interference from other devices. With a dual band router, you can browse the Internet on the 2.4GHz band while streaming HD movies on the 5GHz band and neither band gets overloaded. In short? Dual band means less interference and faster speeds. All Wireless AC routers and select Wireless N routers offer dual band functionality.

You’re always on-the-go. Whether you’re travelling for work or pleasure, you need continuous and reliable Wi-Fi for all your devices. You need a router you can throw in your carry-on and take along for the ride. D-Link recommends the Wi-Fi AC750 Portable Router and Charger (DIR-510L)

Tri-Band Connectivity

With Tri-Band routers it’s simply adding another band, specifically another 5GHz band. With multi band routers it’s easy to think of it as a highway, with each band added the less chance of traffic and congestion there is even as more and more cars (devices) are added. So for the households with multiple Wi-Fi users all using multiple devices and maybe even throwing in a few connected home products’ the more bands your router has the better connection all your devices will get. Tri-Band is a fairly new concept but if you’re interested in a Tri-Band router check out our AC3200 Ultra Wi-Fi Router (DIR-890L/R).

Tri-Band (1)

Wireless Signals & Beamforming Technology

In typical wireless routers, Wi-Fi signals broadcast using multiple antennas and Multiple Input Multiple Output (MIMO) technology. MIMO allows for higher data transfer rate due to the transmission of multiple data symbols by simultaneously using multiple antennas. The Wi-Fi signals are broadcast in a donut shape pattern from the router to blanket the area with Wi-Fi coverage. In more advanced routers, beamforming technology is added, which provides additional performance and coverage to devices. Rather than emit Wi-Fi waves in a donut shape, routers with beamforming technology find and track devices on your network and aim Wi-Fi signals directly at them, providing a much stronger signal especially beneficial for mobile devices.

Quality of Service (QoS)

Routers with QoS traffic controls track the type of network traffic (web surfing, online gaming, Skype®, Netflix® and so on) and decide which application deserves higher priority. This improves your online experience by ensuring that high priority traffic like Netflix is prioritized over other network traffic ensuring the best video quality and user experience across all devices on the network.

mydlink Cloud ServicesGigabit Ethernet

Ethernet ports are available in two speeds: Fast Ethernet, offering speeds of up to 100Mbps, and Gigabit Ethernet, clocking in at up to 1000 Mbps. If you want the fastest wired speeds available, you want Gigabit Ethernet.

Cloud Services

Routers with Cloud Services let you access and manage your home network from anywhere. If you want remote access, consider a D-Link Cloud Router. The free mobile app makes it easy to see (and block!) devices connected to your network, view web browsing history and more – all from your Smartphone or tablet.
