Common DIY Security DVR and Camera Mistakes

A security DVR or NVR is a vital component in a security camera system. Knowing how to choose a security camera system with the correct video management device is extremely important.

However, even if you do purchase a complete surveillance camera system equipped with a quality DVR or NVR, there are still more factors to consider. Security camera installation alone will be crucial to achieving the highest level of security available with whatever type of video surveillance system you choose.

The article below will explore some of the various mistakes that are commonly associated with people who choose a DIY approach when it comes to choosing and installing their security camera system.

Common DIY Security DVR Mistakes

Overall Budget 

Many people don’t budget properly to accomplish their security goals. When first considering surveillance cameras, be sure to look at the specs of each one. A security camera that costs $200 and a security camera that costs $50 will generally be different in terms of image quality and functionality. 

Also, be sure to look at the features of the security DVR or NVR. Although low-cost, full security camera systems are available, they will often lack basic features, such as motion detection. You should also consider the advantages of professional security camera installation if you want to maximize the effectiveness of your surveillance solution.

Security Camera Placement 

Surveillance camera placement is one of the most important factors for having an effective security camera system. Consider asking some questions when placing the cameras. 

  • How does the light come in throughout the day? 
  • How will this change at night? 
  • What am I looking to monitor? 
  • How much movement is there in this area? 
  • What sort of blind spots are there? 
  • What sort of security camera lens is best for this position? 
  • Are multiple security cameras needed to have full coverage of the area? 
  • Is a side view or a straight view more appropriate?

Choosing the Best Security Cameras 

When looking at security cameras, understand what you are trying to do. Are you looking for license plate recognition? If so, then you need to select a camera lens that will allow the plate to be at least 1/3 of the image. This means that a surveillance camera with a wider field of view cannot successfully do license plate capture. 

The same goes for facial recognition and other close-up details. Knowing the role of each security camera you need will help to decide the best types of security cameras for your applications.

Choosing the Right Security Camera Lens 

Selecting the right camera lens isn’t as hard as some people might think. However, it is one of the most important factors for having an effective surveillance system. After you know where you are going to place the camera, determine where you will have it pointing. 

Measure the distances between that point and the camera. That is your focal distance. Next, measure the width of the image you want to see for your field of view. Once you have these numbers, input the data into a CCTV lens calculator

Best in Class IP Cameras

Infrared (IR) Lights & Night Cameras

Infrared cameras are wonderful for monitoring low-light environments. However, not all IR cameras have the same Lux rating, meaning some are better than others at nighttime monitoring. 

Certain night cameras are designed to record details with virtually no light present. Among the most popular low-light surveillance devices now are Starlight security cameras due to their overall effectiveness for monitoring conditions, including complete darkness.

Cabling – Wired or Wireless Camera Systems

Older analog CCTV systems used a completely wired setup. Wired setups of this kind are still used in certain scenarios but they are also known to have various limitations. Wireless camera systems, on the other hand, are more popular because of their innovative advancements. Integrating these two types of surveillance camera systems is also possible.

IP network security cameras connect and transfer data over an internet connection. Though most network IP systems are not completely wireless, they are easier overall and often only require a single cable to be connected to the camera. However, IP cameras are generally more expensive and will sometimes require a separate Wifi network, which generates additional costs.

Image Quality 

How high the quality of the security camera image is will depend on a few factors, such as camera lens, focus, overall resolution, and how good the S/N (Signal-to-noise) ratio is. When looking at a camera, you generally want both the highest resolution and the highest S/N ratio you can find. 

The major difference between choosing higher-quality cameras with a higher resolution capacity is that the details they record will actually be useable. This clear, crisp evidence can be the difference in capturing key details to assist in identifying potential suspects.

Overall Frames Per Second (FPS)

Many security camera companies will promote their security DVR / NVR options with the highest frame rate. However, high frame rates are not always in everyone’s best interests from a storage and budget perspective. 

The reason to avoid higher frame rates is that they take up more drive space, reducing the total storage time of the system. It can also divert budget away from selecting the right cameras, a far more important factor for generating clear evidence than a frame rate alone.
