Raytec Vario IP Illuminators

Author: Ethan Ace, Published on Jan 27, 2013

Raytec may have the first ever networked surveillance illuminator. The big question is what this means. What are the practical benefits of an IP based illuminator and is it worth switching from traditional ones? In this note, we look at this new line, how it compares to existing options, and best potential applications.

This is the first comment on our new IPVM commenting system :) (uses the same code/features as IPVM discussions).

Here's my wish list item - not sure if it will work. If you could integrate an add-on IR illuminator with an IP camera, you could dynamically adjust the illuminators intensity based on activity in the scene. This type of 'smart IR' if only available now for cameras with physically integrated IR but that, of course, suffers from short distance limitations.

If you took Raytec's API, added an app to Axis camera, used some basic analytics to detect where objects were, you could dynamically adjust the light levels (the Axis app sends command to the Raytec IP illuminator). I am not sure how well this would work nor if it could be quick enough but it would be neat.

Does 'burst' add any distance at all?

Good question. Presumably yes because higher the power, the greater the distance that can be achieved.

The boost function delivers 20% more power for a short period. Becuase of the inverse square law this equates to 10% more distance. So its designed for 2 things:

1) if an event happens right on the edge of a cameras range (remember cameras should cover each other so the extra 10% distance is to help cover grey areas)

2) If the camera starts to 'hunt' for focus due to a lack of light as the camera zooms then the boost can help with the camera focus point.

Of course it can also be useful if non-reflective materials are being worn. It can help to counteract worse than average scene conditions.

An advantage to RS-485 (from an installation cost perspective) is it's ability to be daisy-chained.

James, so overall would you prefer 485 or ethernet? i.e., for illuminators

Wow, an IP, web browser accesible and managable IR Illuminator?!?! Is it the year 2000 already? I so love the incredible advances the security industry makes. =)

BTW, on the comment section, in my Firefox 18.0.1 browser, the ends of the sentances are cut off. for example, the portion of the first sentance is all I see, "This is the first comment on our new IPVM commenting system :) (uses the same code/feat"

@ Luis - we are working on the text formatting issue you mention. It can be seen in more than only Firefox.

"Re: Is it the year 2000 already?"


In the Competitive Comparison section, the third key feature bullet is not entirely accurate. The NuOptic VIS illuminators can be placed in a "shadow mode" in which they respond to all commands targeted to a specific RS485 bus address. Using this mode, multiple VIS illuminators can all be controlled in unison by simply sending control commands to one unit.

So for example, 4 VIS units could be daisy-chained on an RS485 bus with addresses 32 through 35. Units at addresses 33 through 35 are put in "shadow address 32" mode. Then any brightness, ambient threshold, or FOV commands sent to the VIS unit at address 32 will cause all 4 units to respond appropriately, as if they were all one unit at bus address 32.
