Video surveillance is becoming a mainstay in restaurants and retail establishments. Managed video software helps with loss prevention, human resource, brand equity, operational excellence and so much more. With that said, owners and operators rely on recorded or live video to answer questions or provide important details in various situations. But, what happens when the video being recorded is fuzzy or unclear? Should you replace your security cameras?

Security Cameras in Restaurants or Retail Need to be Clean to Perform

It’s easy to check the cleanliness of your security cameras via a network video recorder (NVR). Does the image seem blurry or fuzzy? Most likely a simple wipe of the dome will do the trick and restore clarity.

Depending on where cameras are located or their position, they may have different cleaning needs. For example, an outdoor camera may collect pollen or dust if it’s located in an area that doesn’t get a lot of wind. Clean cameras according to where they are located:

  • Kitchen cameras should be cleaned twice a year. 
  • Outdoor cameras should be cleaned 2 to 3 times a year, depending on weather and location. 
  • Cameras located inside where debris is at a minimum should be cleaned about once a year.

To clean the dome cover, use a soft microfiber cloth with an ammonia-based cleaner or light soap and water solution. You may also clean the cameras using compressed air to blow the dirt and dust off the lens. You should notice an immediate difference in the video quality on your NVR system.

Clean, Old Cameras Will Never Match New Cameras

Generally speaking, cameras will last anywhere from 5 years on up, keeping in mind the technology is only 20 years old. According to Security-Net, a new, current IP camera should last 2 NVR cycles. An NVR cycle is typically between 3-5 years.

As with cell phones and other video software, camera technology continues to improve year after year. 

  • Digital family photos taken five years ago pale in comparison to those taken on the latest smartphone. Your in-store video system is no different. 
  • Aging analog cameras will not give you the same crisp and clear images as newer higher resolution camera options. 

Envysion recommends 1080p resolution to produce a high-definition, high-quality video.

  • Therefore, 90+ days of video retention on-premises will be available at high resolution on an NVR.
  • Higher resolutions are also supported for specialized use cases, like 360-degree cameras and areas where greater detail is desired.
  • Replacing analog cameras with IP cameras will capture crystal clear video.
  • Proper camera configuration will optimize both video quality and storage space on an NVR system.

Fuzzy Cameras Are a Choice

Overall, keeping cameras clean will help in the clarity of the video and they will last longer. Depending on your video security needs, you may opt to keep the analog cameras on-site or upgrade to the new IP cameras or even the multi-sensor cameras. While cameras do fail at times due to functionality or internal technology, in the end, fuzzy cameras are a choice.
