So far, your security camera often experiences false alerts due to it detects movements that don’t need proper attention. Amcrest released Amcrest ip8m-t2669-ew-ai series of 4k turret security cameras with AI technology. How good is it compared with new Reolink rlc-820a knowing that the price difference between these two models is quite a lot?
What this product does
Previously, Amcrest had released couple of 4k turret security cameras including the Amcrest ip8m-t2499 with a fixed lens and also Amcrest ip8m-mt2544 with 3x optical zoom. However, these two models are not equipped to support AI (artificial intelligent) feature that can recognize human and vehicle detection like this new Amcrest IP8m-t2669-ew-ai series.
To reduce false alerts from motion detection which is often triggered by object movements that do not need serious attention such as fallen tree leaves, pet movements such as cats, dogs or ferrets, the ip8m-t2669ew-ai is equipped with AI technology features that detect human and vehicle. This AI feature can be enabled or disabled as needed. Today you can find lots of security camera products with AI feature including the new Reolink rlc-820a.

Besides the AI face detection feature, the ip8m-t2669 is also equipped with other IVS (Intelligent Video Surveillance) features such as tripwire intrusion detection as perimeter protection which can provide smarter and more efficient security system than standard motion detection.
Amcrest provides a resolution of up to 4k @ 30 fps real time rate, but if this AI feature is enabled, the frame rate drops to 4k @ 20 fps, a slightly lower frame rate than @ 30 fps real time and this is the default setting. See also new model of 12MP security cameras offered by Reolink and Annke.
If you compare it with Reolink rlc-820a you can find that Reolink doesn’t support tripwire like Amcrest does, and Reolink offers resolution up to 4k @25 fps with AI face and vehicle detection feature.
Amcrest ip8m-t2669 comes with Starlight CMOS for brighter night vision even in low light condition, or with ambient light above its minimum illumination you can find color night vision. Amcrest offers wider diaphragm (f/1.4) as opposed to Reolink which is f/2.0. With wider diaphragm lens opens the more light comes to the image sensor and faster time to capture in low light condition.
Total number of IR LEDs is different; however they demonstrate the same range of IR illumination for black and white night vision when not sufficient ambient light can be used to render color night vision.
For color night vision camera, see also OEM product – Hitosino 4mp color night vision.
Amcrest offers true 120dB Wide Dynamic Range (WDR) for better compensation in challenging extreme light difference between overexposed area with too light and underexposed area with too dark.
We know that if in a photo frame there are two conditions of strong light and darkness at the same time it will be difficult to get a more detailed image, the result could be too dark or too bright on the other side with less detail. For this reason, the security camera is equipped with the WDR feature which is typically using certain number of dB notation, and 120dB specifies true WDR (with mechanical and software approach) as opposed to full software approach (with less quality).
Please refer to the following spec comparison table for more detail differences (if any) between Amcrest ip8m-t2669-ai and Reolink rlc-820a.
