Front Door Video Cameras

Our residential security systems allow you to add a front door video camera.

Front door video cameras let you engage in remote home monitoring, a helpful tool when you want to do any of the following.

  • Protect your family: Remote monitoring lets you keep an eye on your loved ones back home while you're at work, running errands or out of town. Front door cameras help you monitor who is coming and going, like older adults, children, delivery professionals and pets.
  • Monitor vacant property: Planning a vacation or business trip? Front door surveillance will help you protect your home while you're away, so you can enjoy your travels without fear of a break-in or home disaster. It's also the perfect way to monitor vacant rental or investment properties in between tenants.
  • Grant access control: See who's at the door and grant specific access control to the friends, family and utility professionals allowed inside, while keeping unwanted solicitors and other strangers at bay.


Exterior and Interior Security Cameras and Installation

Interior and exterior residential camera systems offer a comprehensive view of your chosen points of interest, like your front porch, indoor entry room, backyard or garage.

Interior and exterior security systems can help deter or prevent:

  • Home intrusion or burglary.
  • Intentional and accidental property damage.
  • Package and delivery theft.
  • Home damages resulting from a fire or burst pipe while away.
  • Children sneaking in or out of the home.
  • Medical emergencies in pets and unattended family members.

Whether you want to monitor your front porch deliveries or get an inside look at what happens in your home while you're away, we can help you customize your camera system to fit your exact needs and budget.

All residential security camera systems include high-definition capabilities with built-in night vision. Review saved footage easily with zoom capabilities and helpful motion indicators, so you can fast-forward to the parts of your surveillance footage that concern you.

Smoke Detectors and Fire Alarms

Security systems and front door cameras can keep you safe from outside threats, but what about those that lurk indoors? Having an efficient smoke and fire detector can significantly reduce the chance of fire-related devastation. Smoke detectors and fire alarms from Knight Security Systems are responsive and reliable, with 24/7 assistance when you need it most.

Our monitored smoke detectors connect to your home security system and alert you when they identify smoke or flames in your home. As the audible alert signals through your household, the system sends a secondary alert to our central station and your nearest fire department for instant response.

Monitored smoke and fire alarms will help you sleep better at night and provide an added layer of protection when your home is vacant. In some cases, investing in fire detection may also qualify you for a discount on your homeowner's insurance.

Carbon Monoxide Detectors

Carbon monoxide has no taste, smell or visible indication that it's infiltrated your home. Without a CO alert system, homeowners may not notice the presence of carbon monoxide until they start experiencing severe, often life-threatening symptoms, like fatigue, headaches, dizziness and reduced brain function.

Carbon monoxide can leak from multiple sources, including:

  • Gas space heaters.
  • Chimneys and furnaces.
  • Wood-burning stoves and fireplaces.
  • Gas-powered generators.
  • Vehicle exhaust.
  • Damaged boilers.

A reliable carbon monoxide detector can save your life and protect your family from hazardous side effects. Hard-wired and wireless monitored carbon monoxide detectors from Knight Security Systems are similar to our home smoke and fire alarms. They integrate with your home security system and initiate a dual alert when they detect dangerous CO levels. One alert is a loud audible signal to notify you and your family to evacuate the home immediately. While this alarm signals through your house, the system sends a second alert to our central station and your local fire department for fast assistance.
