Important Considerations for IP Network Cameras

Post on 20th of March, 2014
Before you purchase an IP security camera, it's important to determine the needs for your security application. Here are a few considerations to help with the process:
What form factor(s) are most appropriate?
Will you be monitoring indoor or outdoor environments?
What level of detail do you need to see?
How many cameras do you need?
What about low light conditions?
Do you have enough network bandwidth?
Is your IP camera compatible with other IP devices?




Before you purchase an IP security camera, it's important to determine the needs for your security application. Here are a few considerations to help with the process:

- What form factor(s) are most appropriate?
- Will you be monitoring indoor or outdoor environments?
- What level of detail do you need to see?
- How many cameras do you need?
- What about low light conditions?
- Do you have enough network bandwidth?
- Is your IP camera compatible with other IP devices?

Do You Need an Indoor or Outdoor Camera?
If you plan on monitoring outdoor locations, you'll need an IP camera with a weatherproof enclosure. Make sure it has a sufficient IP weather rating to withstand the elements in your area. If you need to target high crime areas that are prone to vandalism, you'll want a vandal-proof network IP camera. Review the security camera specifications to make sure you get the appropriate camera for your application.

What Form Factor Do You Need?
There are many benefits to each camera form factor, and the design you choose should support your unique security needs. Do you need a dome camera with an obscured lens angle or an inconspicuous mini-dome camera? Would you prefer a pan/tilt/zoom camera with a powerful optical zoom, 360° panning and wide area of view? Or, do you need a compact, inexpensive cube camera for indoor surveillance? Or do you need a weatherproof outdoor bullet camera with day/night capabilities? Ultimately, it's up to you to decide which type of form factor works best for your surveillance needs. 


What Level of Detail Do You Want to See?
When choosing an IP camera, it's essential to know what level of detail you need to see in your video. Do you need to view a wide area, or see video of cars driving by; or do you need to zero in on a face or a license plate to provide evidence for a case? A high resolution camera with the appropriate lens will allow you to see your video images in great detail.


ResolutionResolution
IP camera resolution image quality is measured in pixels. A highly detailed image is made up of more pixels and contains more data than a less detailed image. IP camera resolution is defined by the number of horizontal and vertical pixels (e.g. 1280 x 1024 resolution).
The resolution of the camera and lens will dictate what you will be able to see. The camera resolution defines the level of detail, while the camera lens determines how far away the image is from the camera and how wide of a viewing area or field of view (FOV) that you'll be able to see.


Field of ViewField of View
The camera's field of view also affects resolution. The field of view (FOV) is the viewable area of a given scene captured by the camera. It is also referred to as the angle of view or angle of coverage. FOV is determined by three elements: the lens and sensor element within the camera and where the camera is positioned in relation to the scene. A large FOV generally results in the target object being relatively small, compared to a camera with a small FOV.



LensesLens Selection
Your camera lens affects resolution as well and determines the field of view you will see. A camera lens with a higher focal length number will deliver more magnification; while a lower lens focal length number will provide less magnification but a wider field of view. If you choose a high-resolution IP camera, then you need to select a high-resolution megapixel lens in order to maintain the resolution required to deliver a clear, detailed image. If your camera sensor delivers a high resolution, but your lens does not deliver a resolution that’s equal to the sensor’s resolution, then you’ll get an image that’s not as crisp and detailed.

 
What About Low Light Conditions?
Choosing a camera with features that support low light environments is also very important in regards to image quality.

True Day/NightTrue Day/Night
A camera with true day/night functionality delivers clear, crisp images in low light conditions. This feature is one of the most important factors in a camera's low light performance. The camera automatically removes the infrared filter from in front of the imager which enables the camera to see near infrared light. It allows more light into the imager to deliver a clearer picture and minimizes distortion in black and white mode.




Wide Dynamic RangeWide Dynamic Range
Wide dynamic range (WDR) is also an important factor in determining a camera’s ability to produce a clear image in diverse lighting environments. WDR balances the contrast of light and shadow. This feature enables the camera to deliver clear video with near perfect exposure in harsh lighting conditions, such as in extremely bright, dark or backlit areas within a scene.



Do You Have Enough Network Bandwidth? 
IP security cameras require network bandwidth to transmit and store images, video and data. The more cameras you have connected to your network, the greater your bandwidth requirements. High-resolution cameras also require more bandwidth. IP cameras use video compression to help reduce video file size and optimize network bandwidth and storage capacity, while maintaining image quality.

How Many Cameras Will You Need?
When choosing an IP camera, it's important to assess how many cameras you may need for your security application. Do you have a large business with many entrances and exits to monitor? Or are you looking to keep an eye on a smaller residential property? Do you have a large college campus with multiple buildings to secure? The larger the property and greater amount of areas to monitor, the more cameras you'll need.

Don’t Forget About Power
Many IP cameras have a Power Over Ethernet (PoE) feature that allows you to power your IP camera through your network cable. If your IP camera does not have PoE, you’ll need to use a separate power cable to power your security camera.
