Blink Outdoor Camera Comparison: 3rd Gen vs. 4th Gen

The Blink Outdoor 4th generation camera introduces several notable enhancements over its predecessor, the 3rd generation model. 

One of the most significant improvements is the wider field of view, expanding from 110° diagonal in the 3rd gen to 143° diagonal in the 4th gen. This enhancement allows users to capture a broader area, providing better coverage and potentially reducing blind spots.

In terms of image quality, the 4th gen promises improved clarity, especially in low-light conditions, ensuring that users can see clearer footage even in dimly lit environments. 

The motion detection system has also been refined. While the 3rd gen model offered customizable motion zones, the 4th gen goes a step further by incorporating two PIR sensors, which enhances its ability to detect movement accurately, especially in low-light conditions. 

This improvement, combined with AI technology and Person Detection (Paid For Extra), aims to reduce false positives, ensuring that users are alerted to genuine motion events.

Another design change is the relocation of the speaker to the side of the 4th-generation camera, which will affect the audio experience during two-way communication. I initially thought that the slot on the side of the camera was an SD Card slot, but that is where the speaker is located now.

While both models are designed for outdoor use, the 4th gen camera loses its weatherproofing when a USB is connected. This is a huge consideration for those planning to provide power to their outdoor camera. 

“Designed for outdoor use, the Outdoor 4 camera can only be safely powered by using two, AA Lithium batteries. The Outdoor 4 can be powered through its USB-C port using a weather resistant USB-C adapter; however, once the port cover is removed, the camera is no longer weather-resistant.”

Blink Outdoor 4 FAQ

Here’s how Blink recommends powering the 3rd-gen outside via USB.

The Blink Outdoor 3rd generation camera has dimensions of 71 x 71 x 31 mm, while the 4th generation model measures 70 x 70 x 41 mm.

Both generations are almost identical in width and height, with the 3rd gen being just 1 mm wider than the 4th gen.

The most noticeable difference lies in the depth. The 4th gen is 10 mm deeper than its predecessor, making it slightly bulkier in this dimension.

Lastly, the motion sensor in the 4th gen is more concealed, offering a sleeker look while still maintaining its functionality with the inclusion of the two PIR sensors.

The Blink Outdoor 4th generation camera offers a series of upgrades that enhance its performance and user experience, making it a worthy consideration for those looking to invest in a new outdoor security camera.

    1. In my opinion, the easiest way to quickly differentiate each generation is by their physical appearance. If you’re not familiar with what each generation looks like, pictures of each generation can be found on the Blink Support website by clicking the appropriate category:

      Another options is to open the battery cover and look at the model number:

      bcm00100u: Blink Original Indoor Camera
      bcm00200u: Blink XT2 – 2nd Generation Indoor & Outdoor Camera
      bcm00300u: Blink Mini Indoor Camera
      bcm00400u: Blink Outdoor – 3rd Generation Outdoor Camera
      bcm00410u: Blink Indoor – 3rd Generation Indoor Camera
      bcm00500u: Blink Outdoor 4 – 4th Generation Outdoor Camera
      bcm00600u: Blink XT – 1st Generation Indoor & Outdoor Camera

      I don’t know why Blink decided to give XT the model number they did, but it is the only one out of order. It also means the next generation of Blink camera won’t be able to go in sequence.
