Is it normal for the camera to get warm?

Post by DigitalPixel »

I notice that my 4K turret cameras (IP8M-T2499EW-28MM) get warm. Is this normal?

Kind of need more info about this question...

I have some cameras that have heaters in them does yours?

Does it get warm at night with the IR on? or your talking about normal day?

Is your Camera indoors or outdoors when you see it is getting warm?

What is the Temp around the Camera? If indoor does the camera sit in an area that the Heater when it is on could be blowing Heated air on it? Is it warm because it is in Sun light?

Sorry i am not sure I have enough info to be able to answer the question as there are a lot of different things that could make your camera warm...

I don't have them installed as of yet because I just got them. They are just sitting on the floor on top of their box wired to a PoE switch. They just get warm under normal operation. The IR is not on. I seen a few videos on how to install the micro SD card and there seems to be a heat transfer pad of some sort that is on the board. When the camera body shell gets closed the pad touches the other side. I don't think its a problem, I just want to see if others experienced this.

Here is a video from Amcrest mentioning the heat conductive pad...

My IP8M-T2499EW seemed quite hot sitting on a counter top during its initial evaluation. Enough to make me wonder if this will be an issue outside this summer. Time will tell.

Very interesting... SO here is my Guess... The area that the heat conductive pad as they called it when putting the camera back together is next to the cameras Power Supply.. So the reason this gets hot and one of the things I was thinking it could be when I first read that it might be do to having a Power Supply... So what is this power supply and why does it cause heat... Well the problem is that it is a POE camera and with that the POE Power is going to be in the upward numbers of 48V... Problem is that camera don't need to have so much power and as such there is what is called a Buck converter in there and going to be 2 Bride Rectifiers along with other things, Transformer, inductor resistors and all kinds of things to reduce that 48v down to 12vdc... Then more magic to reduce down to 5vdc this all is going to be though a Resistor and other things and as such will cause heat... Just think of it as your CPU in your computer it needs a Fan with Thermal paste with out it, it will burn up because it is doing a lot... This camera was designed with Heat in mind and the reason they built it as they did.. I am sure summer time will be fine. That turret is all part of the cooling device to help keep it all safe.. I am sure it would be able to withstand what ever temp it says it can on the Camera tech sheet... I have not looked it up but I am going to guess it is much warmer then it gets around here.. Maybe not well working in Death Valley but not much does... Hence the name...

So I am sure not every one has a bunch of power supplies laying around but here is an idea for you to try if you have one.. Take a 2Amp 12vdc power supply with the Center being the 12vdc voltage and the outer being the ground and first remove the Ethernet cord from the camera. Wait about 1 min, Then plug in the 12v power supply to the cord that is next to the Ethernet connection. Once this is plugged in you can plug in the Cat 5 or 6 what ever your using. It can be connected to a normal port on the router or POE as the camera will only take the first power supplied.. ONce your camera is up and running I would let it sit some and see if that camera gets hot.. Problem is the camera really is a 5vdc camera and will also be doing some magic to reduce down to 5 from the 12 your going to give it...
