Effio-E cameras erratic at daybreak

[stano711 0]

We have installed 8 Effio-E dome cameras outside our building. The image live is great. The playback image is relatively good, for playback. After reviewing an entire day of playback/recording we've discovered that at around 10 minutes to 5am four of the cameras begin to act erratically…changing between IR B/W and fuzzy/blurry B/W. Just about a little more than an hour later…6:20am, they are stable(but now in color) again. The other four cameras remain just fine throughout. The four that have erratic behavior are on the East and South walls. The other four are on the West and North walls. It seems to be a daybreak issue? Is this fixable with an adjustment?

I'm guessing they have OSD menu? You could try different day/night settings. Sometimes besides the usual choices there are different EXT [external] choices such as EXT1, EXT2, and so on. You could try them and see if it helps the camera make the change from dark to light more smoothly. Also there may be other settings such as these from a camera manual I have to try and see if it helps-

 

Delay CNT – This setting tells your camera how long to delay before switching to either day or night mode. This setting is handy as it will prevent the camera from switching over to either mode too quickly because of a temporary light change. The higher the setting, the longer the delay

 

Day-Night – Tells the camera when to switch over from day mode to night mode. The higher the setting, the less light that is required for the camera to switch over. For indoor scenarios, we recommend keeping this setting somewhere in the 40-75 range. For outdoor

scenarios, we recommend keeping the setting around 150.

 

Night-Day – Tells the camera when to switch from night mode back over to day mode. The higher the setting, the more light is required for the camera to switch over. For indoor scenarios, we recommend keeping this at 50-85. For outdoor scenarios, around 175.

 

**** Please set the values between Day-Night and Night-Day to be somewhat distinguishable. If the difference between the values between these 2 settings are minimal, then you may have a problem of the camera switching between modes repeatedly. Also,

you will notice that the Night-Day setting must always be higher than the Day-Night setting. This is a value that may take a few days to toggle with in your scenario to get the right setting

These are Color/IR cameras. Regarding the Day/Night Ext1 and Ext2; Quoting the manual, "IR camera does not have this feature. Instead, it detects lux using CDS, and turn on IR LEDs. Then the video of the camera changes to B/W mode."

 

I've asked the vendor and he advised putting one of the stable cameras in place of an erratic camera and see if that makes a difference. Pardon the expression, but kind of like shooting in the dark. Will try it if there is nothing else.
