Can Sight, Sound & Security monitor my existing security system?

In most cases, yes. However, we would be doing the home owner a disservice by not coming to the site and doing a no cost, no obligation security analysis of the property. We will make recommendations and determine if the exiting system is adequate.


What is HDTV?

What kind of HDTV you buy depends on your needs. Here's a rundown of the current display technologies. Each one has benefits and limitations, so make your choice based on the features most important to you.


What's the difference between enhanced definition (EDTV) and high-definition (HDTV)?

HDTV includes picture resolutions of 1,080 interlaced and 720 progressive and 1,080 progressive. EDTV resolution is 480 progressive, equivalent to the video output of progressive scan DVD players. EDTV looks much better than today's standard analog, but shouldn't be confused with true HDTV. HDTV is by far the better option. 


What are the pros and cons of having a wireless or wifi home network?

Pros

  • Ideal for mobile applications
  • Freedom of movement
  • High performance for most common network applications

Cons: 

  • Limited bandwidth and range.
  • Vulnerable to interference and drop-outs.
  • Less secure than wired networks. 

What is the difference between a router and a modem? 

It's easy to get confused because both are so similar. They both do similar things, but differently. 

The modem brings in the information from the provider. The router takes that information and distributes it out locally or to a local area network (LAN).


What is the difference between CAT5 wire and CAT6 wire?

CAT5 was developed to support fast 100 BaseT ethernet standards. When gigabyte ethernet (1000 baseT) standards were introduced, the CAT5 cable became vulnerable to crosstalk, which caused interference and signal loss within the transition. 

CAT5e supersedes CAT5. It was designed to reduce crosstalk when transmitting 1000baseT ethernet. The 'e' in CAT5e stands for 'enhanced.' It is the most widely used cable in residential installations today. 

CAT6 was designed to transmit 1000BaseT at gigabyte speeds, it is 4x faster than CAT5e. CAT6 is a wider cable than CAT5e with more twists within its pair to reduce crosstalk. 


What specifications are most important on security cameras?

One of the most common differences between security cameras is the resolution offered. Camera resolution is measured by the number of horizontal lines the camera chip produces. It is referred to as lines or TVL. The more lines of resolution, the higher the image quality. Standard quality ranges from 380 TVL to 420 TVL, high quality ranges from 420 TVL to 480 TVL, very high quality is anything above 480 TVL. 


What is the difference between a fixed camera lens and a varifocal lens?

Varifocal and fixed lenses are the two most basic types of lenses pertaining to security cameras. Varifocal lenses are adjustable, where as fixed lenses are not. Consequently, varifocal lenses are more expensive, but are ideal in places where the focal point may change or vary. Fixed lenses typically come as 3.6 mm or 4mm and can accommodate most scenarios. 


When do most burglaries happen?

Burglar statistics vary, but in general a burglary occurs about 10 seconds in the United States. The vast majority of burglaries take place during the day when people are not home, normally between 9 am - 4 pm. This is when homes are most vulnerable. Property loss from a burglary averages about $1650.


Does a monitored security system deter a burglar?

Interestingly, the main entrance of your home, normally the front door, is used in over 1/3 of all home burglaries in the United States. However, homes with a monitored security system are 3x less likely to be burglarized than homes without such systems.


What is the difference between a HiDef 1080p HDTV and a 4K UHD TV? Should I upgrade?

The difference between these two technologies in practical terms is simply the difference in overall pixel count. HD 1080p resolution is just over 2 million pixels. 4K 4320p contains over 8 million pixels. Each 4K pixel will be much smaller than traditional pixels, and has become known as a "micropixel." Now that 4K content and up-converting devices are more prevalent, the cost/value proposition is up to the end user. The 4K UHD ( Ultra High Definition Television) is becoming increasingly more affordable.
