Parts of a Home Security Camera System

What makes a home security camera system the one for you and your family? No matter where you live in Florida home security is important to protect those who are the most important to you and the comfort that is your home. diagram-146967394Whether you choose to go DIY or call in a professional service for your home security system, it’s important that you make sure you’re getting customized security for the needs of your home instead of simply generic home security services. To help you understand what your home needs for home security, we’ll address the main parts of home security camera systems and the options you have.

Analog, IP or HD-SDI

One of the primary decisions that must be made as you design the perfect security system for your home is this: “What can we afford?” Many people don’t think they can afford any kind of security because it’s just a “luxury”. We’d like to submit that everyone can afford some security. For those who are living on a tighter budget, analog systems are probably your starting ground. For those who want the best of the best, you’re going to want to look into HD-SDI.

  • 827585_75890335Analog: This is the old-fashioned broadcast quality data transfer as TV used to be. The image quality isn’t exceptional because only so much information can be sent across the broadcast, but the devices are affordable and can probably be self-installed.
  • IP systems: IP cameras utilize a digital signal, meaning your resolution is fairly decent in quality as it relies on megapixel resolution instead of TVL (analog). These cameras require a NVR or network video recorder, which has a limited capacity for playback. Fairly complex, the IP system should probably be installed by a professional.
  • HD-SDI: This system will give you incredible playback ability and the best video quality possible for a surveillance system. They’re fairly self-explanatory and can often be DIY installed, but the systems are FAR more expensive because they require higher quality cameras and more storage space on the hard drive to contain all the information being collected.

Choosing the Camera

When choosing the cameras for your home security system there are a few things you need to begin by considering the NUMBER of cameras you’re going to need to optimize the surveillance coverage of your property. Every door should be covered since 90% of break-ins come right through your door.  Every window should also have a device, and if it’s not going to be a camera, you should probably have a broken glass sensor. The number of devices you’re going to need will affect what kind of cameras and system your budget can afford.

When choosing a camera you’re going to want to consider:

  • Image Resolution
    • Analog has measurements of 420 TVL, 550 TVL, and 700 TVL
    • IP & HD-SDI have 720p and 1080p.
    • Camera style
      • Dome style: indoor outdoor cameras that are protected by a transparent dome from the weather and vandalism.
      • Bullet style: these are most commonly outdoor cameras designed to view longer distances.
      • “PTZ” cameras: these are cameras that can be remotely controlled to pan, tilt and zoom while giving live feedback.
      • Hidden cameras: these small cameras are also known as Nanny Cams and can be placed in plain sight as inconspicuous monitoring of indoor spaces.


The digital video recording device that you choose is going to also narrow the playing field of who you can go to, or who you go to will narrow your options. Depending upon how much you want to record, how long you want to save it, and what resolution or amount of information you want to record with every second of footage, your options will change. Still, you have a few:19-08-3 copy

  • Standalone DVR is an option that works just like your regular DVR and allows you review footage live, remotely and on playback after the fact.
  • PC DVRs are entire computer servers designed and dedicated to storing footage from your surveillance systems.
  • HD-SDI are systems which have large amounts of storage space to allow you to save lots of footage at high resolutions for playback and live feed.

DVRs can host 4 channels, 8 channels or 16 channels, depending upon the number of doors and entries you want to cover you should choose accordingly.


You can choose to self-monitor or you can choose to have professionals monitor your security system. Both can be reasonable in cost, and both can be hooked up to remote security control.

Of all the options, most important is that you get the home security camera system that’s going to work the best for you and your personalized needs.
