Cameras are one of the most basic perimeter security devices. They monitor an area and provide you with a live video of that area. Cameras are the most common perimeter security devices used in urban areas. However, surveillance cameras are not perfect. Without proper lighting, cameras cannot provide consistent image and video quality. So how do you get reliable perimeter security? You combine cameras, lighting, and sensors. Let’s look at the five best outdoor security cameras in 2021.

Best Outdoor Security Cameras 

Following are the top surveillance cameras for this year.

  • Eufy Cam E 1-Cam Kit 
  • Lorex
  • Arlo Pro 2
  • Arlo Pro 3
  • TP-Link Kasa Cam KC200

As mentioned before, lighting plays an important role in ensuring the optimal performance of your cameras. Furthermore, if you have proper lighting around your property, you can easily identify intruders when you catch them on camera. However, any lighting system does not work. You also have to place lights in a position so no unwanted shadows are created. Moreover, good lighting itself is enough to deter intruders because intruders prefer badly lit or dark properties to trespass into.

CAST Perimeter Products Lineup

Following are our five products designed for perimeter security:

  • CPL2
  • CPL3
  • CPL3IR
  • Wall Pack Light
  • Infrared Wall Pack Light

Let’s look at our CPLX lighting systems in more detail.


This product has won numerous awards and accolades for its exceptional performance in perimeter security. CPL3 has a wide light coverage (60’ in every direction) and is customizable with different wattages of LEDs. CPL3 comes equipped with our patented FlashGlare technology, which blinds intruders by flashing lights at them.

CPL3IR Night Owl

Do you want a perimeter light that is a good as CPL3 but has infrared capabilities? We have you covered! CPL3IR Night Owl is the infrared variant of the renowned CPL3. Furthermore, the Night Owl can switch between infrared and visible light too.


Surveillance cameras become less effective or switch to a lower-quality black and white mode. CPL2 assists these cameras by providing sufficient light for them while being extremely affordable. At below $200, you cannot go wrong with CPL2!

CAST Perimeter and PROTECH USA

You can create a strong perimeter barrier by combining multiple security systems. CAST Perimeter and PROTECH USA are great examples of this. For instance, you can automate CAST Perimeter lights by pairing them up with infrared sensors from PROTECH such as POLARIS and G-Wall. This reduces the need for human intervention as your perimeter lights can turn into active defenses,


A combination of different security systems ensures your perimeter’s protection. Order today and secure your perimeter. And remember, if it’s not lit, it’s not secure!
