Holiday Safety & Security Technology

Holiday Safety & Security Technology

From this November holiday season has approaches, priority one security has a few suggestions for your wish list! We offer a wide range of technology solutions that not only make your home safer, but provide other enhancements as well.

For Your Home:

·        Panic & Nurse Call Systems and Medical Alert Systems: Alert the authorities or EMS in case of emergency through your keypad or specially-programmed key chains.

·        Pet-friendly motion detectors: Have furry friends? Priority One’s motion detectors are pet-friendly so you can set your alarm without worry when leaving pets at home.

·        Not-so-safe smartphones: Small children aren’t the only users who go on-line from new unsecured devices. From DROIDs to iPhones, many adults and teens will receive consumer smartphones they’ve been pining for this holiday season. And most will immediately start configuring them with usernames and passwords for Gmail, Yahoo!, iTunes, Twitter, Facebook, and perhaps a corporate Exchange server. Unfortunately, a far smaller number will protect those phones with strong authentication—much less data encryption—creating an easy avenue for personal and business identity theft. Always enable built-in smartphone security measures and fill any gaps by downloading third-party security apps.

·        Phone App Configuration: Some packages include app configuration for up to two devices. Our security app allows you to remotely arm and disarm your system and HVAC units, and it will send you emails and text in the event of an emergency in your home or if there’s something going on in your neighborhood, like a power outage.

·        Hazardous hotspots: Whenever you tap Wi-Fi at a coffee shop, train station, or ski lodge, beware of fake Internet hotspots. Surveys show that viral SSIDs like “FreePublicWifi” are advertised by 5 to 10 percent of Wi-Fi clients used in highly-traveled public places. Most are fellow travelers that naively tried to connect to similarly-named fake hotspots in the past. But a few might be criminals looking to snarf logins and passwords. So avoid enticingly-named Wi-Fi peers or networks that are too good to be true, and always protect hotspot traffic using VPN tunnels or SSL/TLS sessions.

·        Latchkey Technology through Total Connect System: Keep your children safe and provide yourself peace of mind with the Total Connect System. Features of latch key technology include:

o   Notification when your child arrives home or if your child is not home by a certain time,

o   Camera compatibility so that you can access clips of who walks through the door with your child,

o   And ability to create limited-access areas (think, gun safes and liquor cabinets) while you are not home.

·        Whole house distributed audio capability: Priority One can install audio throughout your home, creating a zone for each room. You can then select your source of music from an in-wall keypad, iPad or other smart device.

·        Home Theater Systems: Install automated lights, curtains, motorized screens, HD projectors and more in addition to the a/v solutions we provide.

 

For Your Business:

·        Distributed Audio + Video Display Systems: Similar to our residential offerings, Priority One has the expertise to install multimedia technology in your workplace. Available features for your office include: A/V enabled conference rooms, high performance theater systems, and outdoor/all-weather video and speaker systems.

·        Access Control: Managed through an online platform, an access control system can ensure employee safety. Priority One can install these systems for a one-site business or multi-site corporations. With this technology, you can cut back on re-keying needs, manage employee access and decrease walk-in threats.

Basic Fire Rules

·        Fires peak, particularly in kitchens, during the holidays, so remain alert when preparing meals and keep potholders and food wrappers at least three feet away from heat sources.

·        Test your smoke alarms and carbon monoxide detectors, ensuring that they work at optimal level year-round. Replace batteries, as needed.

·        Know where your exits are located and hold regular fire drills that include practicing at least two evacuation routes from every area or building to your safe refuge area.

·        Notify the property manager about exit lights that are broken or vandalized.

·        Never prop open self-closing doors, as they are designed to keep flames and smoke from spreading.

·        Keep exits and stairways free from obstructions at all times. Don’t store things on or under stairways, or on landings.

We hate to be a Scrooge, but cybercrime doesn't take the holidays off. Everyone should keep online safety in mind as 2020 draws to a close. We hope these tips will help you all enjoy a safer holiday and a happier New Year.

Types of Smoke Detector

Five types of Smoke Detector

What is smoke?
Smoke is the collection of airborne solid and liquid particulates and gases emitted when a material undergoes combustion, mixed with the quantity of air that is mixed into the particulate mass.
Smoke particulates are generally grouped in three particle sizes. Depending on particle size, smoke can be visible or invisible to the naked eye.

The five types of smoke detector...

1. Ionization smoke detector...
An Ionization smoke detector consists of the following main components;
  1. a radioactive source, usually Americium-241 that emits alpha particles
  2. a ionization chamber, an air-filled space between two electrodes
The alpha particles pass through the ionization chamber, and permit a small, constant electric current between the electrodes.
Smoke particles that enter the chamber absorbs the alpha particles, which interrupts the electric current, activating an alarm.
2. Photo-electric smoke detector...
An photo-electric smoke detector is a scattered light sensor or nephelometer, that consists of the following main components;
  1. a light source
  2. a lens to focus light into a projected beam
  3. a sensor at an angle to the beam as a light sensor
In the absence of smoke, light passes in front of the sensor in a straight line.
When smoke enters the optical chamber across the path of the light beam, some light is scattered by the smoke particles, directing it at the sensor and thus triggering the alarm.
3. Projected beam smoke detector...
An projected beam optical smoke detector operates on the principle of light obscuration and comprises;
  1. A projected beam transmitter & lens
  2. A light receiver
  3. A light reflector (not in all cases)
The light transmitter emits an invisible beam of light that is received by a receiver in a normal condition.
The receiver is calibrated to a preset sensitivity level based on a percentage of total obscuration. When smoke obscures the beam, an alarm signal is activated.
4. Aspirating smoke detector...
An aspirating smoke detector is a very sensitive light sensor or nephelometer, that works by actively drawing a sample of air and other contaminates through a pipe network into a sensing chamber and consists of the following main components;
  1. a network of small-bore pipes
  2. a particulate filter
  3. a sensing chamber
  4. a focused light source
  5. a sensitive light receiver
When smoke enters the sensing chamber across the path of the light beam, some light is scattered or obscured by the smoke particles, which is detected by the sensor.
The output is analogue and can trigger multiple alarms.
5. Video smoke detection...
Video Smoke Detection (VSD) is based on the computer analysis of video images provided by standard video (CCTV) cameras.
A video smoke detection system comprises the following components;
  1. one or more video cameras
  2. a computer
  3. software to analyses the video signal
The computer uses specialised software to identify the unique motion and pattern of smoke. This unique signal when identified triggers an alarm.
