what are safe outdoor operating temperatures for ac electronic’s such a dvr vhs recording equipment?

I also don’t need smartassed answers I have a reason for asking this question and if your like silver what’s his name and are bothered by this question save yourself time by not answering this. Why do people come in to forums like this to be smartasses? if you have inteligent input please give it . If you don’t spare me the time of having to respond to childish remark’s

Doesn’t anyone look at owner’s manuals anymore!!!?????!

Problems you face with any electronic equipment due to environmental conditions are things like

1. changes in temperature that result in condensation. Obviously

2. Rapid expansion or contraction due to temperature change that may fracture printed circuit traces, components or even the boards themselves.

3. Changes in component values at different temperatures can result in damage or poor function of other components.

4. Discs and tapes are susceptible to damage when operated, or even stored at temperature extremes.

Consumer electronics are typically tested in the design and prototype stage to determine safe operating ranges. Those safe operating ranges are published in user manuals.

Will the device fail if you operate outside those limits? Maybe, maybe not. There are a lot of variables in the calculations as well as some safety margin. Proceed at your own risk.

Its not a smart ass answer. I’ve worked in electronic quality engineering and the answer would vary depending on the specific device, its design parameters, and components used.

You didn’t give enough details about the device or your intended application for me to guess whether stretching the operating parameters might be doable or not.

Bottom line: read the freakin manual that came with the device and find out what the engineers who designed it think.

    First answer is accurate but he fails to mention if the equipment will be shaded or not. Outside air temp is important but if it is a clear day and this equipment is in the sun, the solar heating of the box can be very pronounced in full sun. If you shade it, then the entire solar heating issue goes away and you just have to deal with ambient temperatures.
