Is this a stuck IR filter problem

One of 5442-ASE cams started showing this today, seemed to working fine in the morning and just noticed this afternoon the ping tinge. Checked within the cam itself and it was running correctly in day mode. Tried flicking between day and night mode but the ping tinge remained.

In the end a restart of the cam fixed the issue but am wondering why if it is the IR filter why it randomly enabled during the day?

I had some old Lorex cameras that would get the purple hue. Gave them a whack and you could hear the ir filter unstick. You should be able to hear it click when it switches from day to night and back.

I also had some that were just stuck like that. That’s when I learned Lorex has horrible customer service. They RMA’d two of them. Then my tickets would randomly close when I submitted new ones.

As I had in this thread: IR filter fall - PTZ
Previously during bench testing it did the same but I didn't think twice about it.

After the camera had been mounted; 18 days later the filter would not always move out of the way when switching to daylight.
Now it doesn't switch at all unless the camera is pointed directly down, and falls when tilted back to the horizon.

I have been in contact with Andy to get a replacement.

Did the pink tint gradually increase? So from normal colors to pink tint in a few seconds/minutes? Are was it there suddenly? Can you hear any clicking from the IR filter before or after?

AH...the dreaded stuck IR filter problem, why can't there be a permanent fix for this? :facepalm:

No idea to be honest as the cam is mounted on my driveway, just noticed it was pink in the mobile app, one second it was fine and the next it went pink from what I saw.

I'm guessing there is. Get a camera that can run forced colour at night. No switch to IR should mean no filter switching.

As for mechanical filters, it switches twice a day every day. That's 730 times a year. There's bound to be wear on a mechanical device such as this. Mechanical IR switches are probably a bad idea. Can't it be done in software these days? eg some photo editing programs have IR filters. Isn't it possible to record applying one of these filters to the B&W image at night producing the image required whlst recording without? Unsure. Not a technical guy, but a mechanical switch with thousands of accuations within a few years and exposed to the temperature changes and elements, is a recipe for failure unless very special attention is paid to component choice ie non temperature affected corosion resistant materials and maybe some way of avoiding moisture in the camera itself such as a heater or air tight seal with maybe an inert gas. I'm guessing those meaures simply don't fit in with budget manufacture.

Would be great but you're right, the cost would be affected and greatly so.....from '79 to '92 I also used to have to maintain CCTV at a vault where money for bus fare was offloaded from municipal transit buses. They were analog, Canon and Sony cams, mixtures of Vidicon and Trinicon sensors, some CCD and toward the end, a few CMOS. But they all were very well made, hermetically sealed and filled with nitrogen...and all were VERY expensive, to the tune of about $300 of some '80s and '90s dollars.

I'm just guessing but today a turret-style, non- PTZ cam made like that would be at least that amount or more....who knows? I do know I would likely have only 4 or 5 at that price. And with camera tech advancing like it does, I like the option of replacing what I have every few years without having to apply for another mortgage on my house! :lol::cool:

I'm guessing that all it takes is a very minute amount of debris gets deposited in the track of the cut filter from wear, and cause's this issue.
The DIY'r in me would make me attempt a repair, by opening the cam, and
1-Using canned air, do a very gentle blast of air in a method that may remove the debris.
2-Tear down the cam further and manually clean the track the filter runs in.
3-I believe I've seen instances where the actuator had to be replaced.

Of course not everyone would want to tackle such a repair attempt. But at times, I'm a glutton for punishment. :)
