5 Reasons For

Mac Compatible

Unlike most of the other low megapixel count webcams that have been available for around the same time as the PK-635 which are not Mac compatible, the A4Tech PK-635 is Mac compatible.

Chart Edit

Features Face Tracking

Unlike most of the other low megapixel count webcams that have been available for around the same time as the PK-635 which do not feature face tracking, the A4Tech PK-635 features face tracking.

Chart Edit

USB Powered

The A4Tech PK-635 is USB powered, which is unusual. Most of the other comparable spec webcams that have been on the market for a similar time to the PK-635 are not USB powered.

We compared all the other USB powered webcams to this webcam and we think the Mediatech MT4040[plb_1998656_price], the Media-Tech MT4040[plb_1754232_price], and the Kloner KWC0078[plb_1854260_price] which is cheaper is also worth considering.

Very Narrow

With a width of only 1.34 inches, the A4Tech PK-635 is one of the narrower low megapixel count webcams that have been on the market for more than two years amongst webcams of this age. Across all the webcams that were released more than two years ago the widths range from 1.1" to 6.6".

Chart Edit

Very Shallow

The shallowest low megapixel count webcam that was launched more than two years ago is 0.9" deep, the deepest is 13", and the average depth is 2.6". At only 0.9 inches, the A4Tech PK-635 is fairly shallow compared to most of the other low megapixel count webcams that have been available for around the same time as the PK-635.

8 Reasons Against

Does Not Have a Motion Detector

Most webcams of this type and age do not have a motion detector. The A4Tech PK-635 is no exception to this as it too does not have a motion detector.

Chart Edit

Does Not Have a Built-In Microphone

The A4Tech PK-635 does not have a built-in microphone, unlike most of the other webcams of this type and age which have a built-in microphone.

We compared this webcam to all the other webcams with a built-in microphone and we think the Media-Tech MT4040[plb_1754232_price], or the Mediatech MT4040[plb_1998656_price] is also worth considering.

Only 640 X 480 Pixels Maximum Video Resolution

This webcam has a maximum video resolution of 640 x 480 pixels, which is the most frequently found maximum video resolution on comparable spec webcams that have been available for a similar time to it.

Chart Edit

Does Not Have a Zoom Capability

Most low megapixel count webcams that have been around for a similar time to the PK-635 do not have a zoom capability. The A4Tech PK-635 is no exception to this as it too does not have a zoom capability.

Chart Edit

Does Not Have a Snapshot Button

The A4Tech PK-635 does not have a snapshot button. Most of the other webcams of a comparable age and spec to the PK-635 also do not have a snapshot button.

It is worth also looking at alternative webcams which also have a snapshot button including the Gembird CAM0360U-1[plb_1284889_price], or the Logitech B500[plb_546296_price].

Does Not Have a Night Mode

The A4Tech PK-635 does not have a night mode. Most of the other comparable spec webcams that were launched more than two years ago also do not have a night mode.

We compared all the other webcams which also have a night mode to this webcam and we think the Gembird CAM0360U-1[plb_1284889_price] which is also cheaper is also worth considering.

Not Full HD

The A4Tech PK-635 is not Full HD, although it is worth noting that most of the other low megapixel count webcams that were launched more than two years ago are also not Full HD.
