Features of Security Cameras and What they Do

  • Resolution ­– surveillance cameras vary in resolution. The amount of resolution your cams come with will determine the quality of the picture taken and video recorded. What does this mean? The higher the resolution measured in megapixel, the better the quality of the image your surveillance camera provides. Most of the best home security cameras available come with 1080p (2 megapixels) resolution, and they offer a sharper and clearer picture quality that surveillance systems with 720p resolutions. A perfect example of a cam with 1080p HD resolution is the best USB spy camera known as HD Mask. Note that the higher the resolution, the higher the storage you will require 
  • Low light performance – there are security cameras that do a good job at taking pictures and recording videos clearly whether in the day or at night when there is low light. Surveillance cameras with day/night capabilities often come with infrared illuminators that provide a light source and help you get better images in darker areas. 
  • Motion detector sensor – most of the surveillance security cameras available in the market today come with motion detector sensor. This allows a wireless security camera system or the wired ones to detect movements in the areas where they are installed. Also, there are some best home security systems that will start recording and alert you immediately motion is detected.     
  • 2-way audio – If you are an individual that have kids or workers (nanny and chef) who work in your home, this feature may be important for you to consider. There are surveillance cameras that allow you to communicate with people at home when you are not around. They have speakers that provide clear sounds and an in-built microphone.   

Additionally, construction material, thermal imaging, wireless strength, the durability of the wire (for wired surveillance cameras), facial recognition, and the mode of installation (easy or a bit difficult to do) should be considered.

Remember, these features can be found in wired security cameras and wireless surveillance cameras. So how do they function?

How Do Wired Security Cameras Work?

Video signals are transmitted to a viewing device such as television or computer through video cables. The wired surveillance camera can be powered through a separate cord or one Power Over the Ethernet cable.

How Do Wireless Security Cameras Work?   

Wireless surveillance cameras transmit video signals and audio signals over a wireless network often the internet to a receiver or recorder that is connected to your viewing and recording device which can be a computer or smartphone. The video footage can be saved in a cloud storage account or other storages like smartphone and computer. 

Installing Surveillance Security Cameras  

Here are the steps involved in installing security cams in your home.

  • Determine the areas of your home you want to put under surveillance. Is it the outdoor, indoor, or both? If it is indoor, how many rooms will undergo surveillance? If it is outdoor, how wide is the area? Also, ensure the area is ethical and legal. 
  • When you get all the questions sorted out, decide on the surveillance camera type(s) you want to purchase and the features you want them to come with. Cameras with dome housing and bullet housing are perfect for outdoors. But surveillance cameras with discreet housing, some dome housing, and some bullet housing surveillance cameras are a good option for indoors. Note that PTZ security cameras and 360-degree or Virtual PTZ security systems can also be used indoors and outdoors. 
  • Once you make the purchase, read the instruction manual of the surveillance system to know how to install it. Most of the times, you can easily install the cameras yourself, although there are times that you will need a professional to help you. However, getting an HD Mask hidden camera phone charger can save you the cost of getting a professional. Little to no installation is required. Just plug the cam in a wall unit, download the app, and see it in action.
