Today’s security camera system equipment is smaller, less expensive, more sophisticated, and is packed full of features. This is great for you as the consumer as you have more high quality options at your fingertips than ever before! However, there are a ton of options and it can be very confusing telling the difference between two particular products if this is your first time dealing with the security industry. You’re going to come across a lot of terms, types of products, and information that you might have never heard of before, but that’s okay! We’re here to help out with that and make this process easy for you. If you have any questions while you read this guide, give us a call at 042-35443103 www.glistensecurity.com and we’ll help however we can!

General Information

This section will help you understand basic camera specifications and their effect on the performance of the camera. Analog camera resolution or picture quality is measured by the number of horizontal lines the sensor chip in the camera provides and is called "TV lines of resolution" or TVL. Naturally, the higher the TVL the better the quality of the image.

  • Standard Image Quality: 380TVL - 420TVL
  • High Image Quality: 480TVL - 520 TVL
  • Very high Image Quality: 1MP - 3MP

Infrared LEDs allow security cameras to see in dark areas by flooding the area with infrared light. This light reflects off surfaces in the area and is picked up by the camera's sensor chip which allows the camera to see as if the area was lit by visible light.

  • # of LEDs: The more LEDs, the better a camera can see in low light environments.
  • Illumination Rage: Refers to the maximum distance at which an object is visible at night.

Vandal resistance is in reference to whether or not a camera is reinforced with a hardened plastic or metal housing so that it is more ruggedly built. If a thief or burglar wants to get on your property bad enough, they will try to damage or break your cameras so they are not seen.

Indoor VS Outdoor Cameras

CCTV Cameras use electrical components that are sensitive to the elements. If water or dust gets inside of your camera, the quality of your video feeds will suffer and your camera may even stop working. Weather proof housings help keep moisture and dust where it belongs, on the outside. If you are installing a camera outside and it is not in a weatherproof camera housing, you will definitely want to double check the camera specs to make sure that it is weather resistance rated. There are many different levels of weather resistance that range from minimal protection all the way to airtight, waterproof enclosures and all of our outdoor cameras are fully weather resistant.

Color VS Black & White Security Cameras

Color cameras are the preferred choice for most security systems. However, black and white cameras are slightly cheaper, more sensitive to light, and can see better in darkness. Infrared (IR) security cameras switch to black and white mode during low light conditions to improve their night vision and return to color in good light conditions. IR cameras have gained popularity because of their flexibility and become the standard type of camera installed in systems today.

Network IP Cameras

Analog security cameras have long been the standard type of camera used in surveillance systems, but IP cameras have surged in popularity over the last five years. When IP cameras were introduced, they were prohibitively expensive and didn't produce noticeably greater quality videos than analog cameras did. However, as the technology has become more readily available and more surveillance companies have invested in developing this technology, IP cameras have dramatically increased in quality and decreased in price which has made them more affordable than ever! IP Camera popularity is on the rise and it is estimated that over 60% of all security camera systems sold over the next few years will be IP based. The advantages of IP cameras over analog cameras are below.

Higher Resolution and HD Video

Megapixel IP cameras can capture High Definition Video (HD Video) and provide greater detail improving identification. A 2 megapixel camera is an excellent choice for capturing license plates and can cover a 24 foot wide point of entry or exit. When monitoring an area, a megapixel camera provides superior image quality compared to analog cameras. We illustrate this below by comparing an analog, 1.3MP, and 2MP image, the license plate in the 2MP image can be easily identified when zoomed into, but this is not the case at an analog resolution. When you need a clear shot of what a person looks like, a megapixel camera image can provide a level of detail that can't be matched by an analog camera. The improved pixel count also allows for the use of ePTZ technology.

Electronic Pan/Tilt/Zoom (ePTZ)

Zoom has always been available with analog cameras, but is often slow and can only be used on live video as events occur and you can't zoom in for more details with a PTZ camera. With megapixel IP cameras, you can zoom, pan, and tilt on live footage and your previously recorded video! The NVR software allows you to select a video clip and zoom in on any part that you want. This lets you catch all the details regardless of when the video was recorded!

Wider Camera Coverage

One of the factors that has contributed to the explosive popularity of megapixel IP cameras is their ability to provide wider coverage and more detail on a per camera basis. A single 2-megapixel IP camera can cover an area 6 times greater than an analog camera. With a 2-megapixel camera potentially taking the place of 6 Analog cameras, the installation costs can be significantly reduced. This is especially true for fisheye IP cameras that come with a special fisheye camera lens. This type of camera records everything in a 360° view and comes in models up to 5 megapixels for high definition video resolution. One single fisheye IP camera can cover a 3,000 square foot warehouse with ease!

Lux & Light Sensitivity

The light sensitivity of a camera is measured in Lux and this is the standard specification you will see that defines how well a camera can see in poor lighting conditions. If a candle is one foot away from an object, it throws one foot candle of light illumination onto the object. This is about 10 "Lux" and is the unofficial definition of Lux. The luminescent value of Lux tries to relate the energy per unit area falling on a surface to what the human eye perceives. We've compiled the table below to give you a better understanding of the concept.

Direct sunlight 100,000 - 130,000 Lux
Full daylight, indirect sunlight 10,000 - 20,000 Lux /td>
Overcast day 1,000 Lux
Indoor office 200 - 400 Lux
Very dark day 100 Lux
Twilight 10 Lux
Deep twilight 1 Lux
Full moon 0.1 Lux
Quarter moon 0.01 Lux
Moonless clear night sky 0.001 Lux
