- IO-Module serves as example for customer's product integration
- Low Power Consumption: approx. 1.5 W (depending on optional components)
- User defined assembly options for mass production
- Branding for customer products possible (program icon, start screen on monitor...)

This table compares the features and options of the mayor V-Recs variants.
Three different Variants of "V-Recs" are available. Major differences are shown in the following table ("[X]" means optional):
| Feature |
V-Recs S |
V-Recs M |
V-Recs L |
| Size (mm x mm) | 32 x 65 | 40 x 75 | 50 x 80 |
| Power consumption, ca. [??? tbd.] | 1.0..1.5W | 1.5..2.0W | 2.5..3.5W |

| Video Output (CVBS/S-Video) | -- | [X] | [X] |
| JPG Image Capture: 720 x 576/480 | X | X | X |
| M-JPEG Video Recording upto
720 x 576/480 @ 25/30 fps¹
(full frame rate needs NANDFlash) | [X] | [X] | [X] |
| MPEG4 AVC Video Recording upto
720 x 576/480 @ 12,5/15 fps¹ | [X] | [X] | -- |

| MMC/SD-Card (external) for Video/Audio Storage | X | X | X |
| NAND Flash (2, 4 or 8 GB) for Video/Audio Storage | [X] | [X] | [X] |
| GPIO-Control (Buttons, LED) | X | X | X |
| USB memory stick for Video/Audio Storage | [X] | [X] | [X] |
| Support for External LCD | [X] | [X] | [X] |
| OSD-Menü on Video-Output during
play-back and control operation | -- | X | X |
| OSD-Menü and live overlay elements on
Video-Output during record and idle
operation (overlay to live video input) | -- | -- | X |
| UART control and data transfer | X | X | X |
| UART streaming (proprietary) | X | X | X |
| USB device ("V-Recs" acts as MSC
storaged device for connected PC) | [X] | [X] | [X] |
| Ethernet control and data transfer | -- | [X] | [X] |
| Ethernet Streaming (RTSP like) | -- | [X] | [X] |
|
--- : Feature not available
[X] : Feature available as option
X : standard feature
¹ Industrial grade systems may only achieve lower frame rates at full resolution, due to lower maximum clock rate.
Also "V-Recs M+" ist available, being identical to "V-Recs M" but allows live overlay elements on video output during idle and record operation.

V-Recs S
Figure 1: Block Diagram "V-Recs S"
"V-Recs S" is a reduced version of "V-Recs M". It does not provide the options Video Output, Audio and Ethernet.
V-Recs M
The block diagram of "V-Recs M" ("M" = medium, i.e. single core) is shown on top of this site. It is the reference implementation of "V-Recs".
The CPU-Module has a size of 40 mm x 75 mm.
V-Recs M+
The more powerful variant of "V-Recs M"
- Live-Overlay on video output
- MPEG4 AVC (H.264) recording at 25/30 fps
The CPU module has a size of 42 mm x 75 mm. (almost pin compatible to "V-Recs M")
V-Recs L
The block diagram of "V-Recs L" ("L" = large, i.e. dual core,) is almost identical to "V-Recs M". The mayor difference to "V-Recs M" it the capability to record MPEG-4 video file in D1 quality (restricted to AVC).
"V-Recs L" is also capable to run the video output on a separate port enabling the following advantages
- connect monitors with different resolution than the connected camera
- time code, text and grafik overlay on life image
- OSD menu control on live image
V-Recs LH
A block diagram of "V-Recs LH" ("L" = large, i.e. dual core, "H" = host) is shown in Figure 2.
Figure 2: Block Diagram V-Recs LH
Externally "V-Recs LH" is similar to "V-Recs M". Instead of USB it provided a flexible parallel host port (16 bit) to provide a high speed connection to a host processor. As "V-Recs L" it the capable to record MPEG-4 video file in D1 quality.
