    This camera includes a PIR motion sensor, that can trip a siren and a white light. Light can flash or come on steady. You can speak from the gDMSS app to the camera.

    You can trip the alarm sound or the white light from gDMSS or from the webGui of the camera.

    Several options can be adjusted for the PIR, white light and siren activity.

    With the exception of Audio noise reduction turned off, time set, and channel name entered,
    All settings at default.
    Camera video recorded and exported from Blue Iris.

    Be sure to choose 4k for play back of the last two videos.
    Me walking up to camera activating PIR and siren.


    In this video, when you hear the hissing noise, that is when the alarm is sounding.

    It could make a good front door or entry camera.

    There is an option to keep the white light steady during the alarm. See if that improves the face washout.

    Can it be set that it work like a motion detect light, just comes on and stay on without the siren to get a color picture at night? Also, it'll attract thier attention making them look at camera full face on too.

    Yes, will test that tonight.
    I doubt the white light is bright enough for a usable color pic. But I'll see.

    My experience mirrors @looney2ns ... it wasn't bright enough for a usable color pic. My camera's on the porch and a decent distance from the person though (about 20 feet), so I'm curious to see if it works differently for others.

    I know some of this can be changed in the WebUI, but my camera takes about 6 seconds after the light comes on and the camera switches to color, then it takes another second or two for the camera to stabilize in color. Chances of someone up to no good still looking at the camera for that many seconds is probably low. I wonder if I can replace the alarm audio file with one that repeats "wait for it..." until the camera has stabilized in color mode? :)

    I ended up setting the Night profile to make the camera stay in B/W mode and then using DahuaSunriseSunset to switch the camera between the Day and Night profiles.

    Couldn't get it to change to color, without manually forcing it.
    Here is the steady spot light test with post lamp on and off. At closest, I'm about 5-6ft away.

    @looney2ns do you have another 8MP camera to compare / contrast it with?

    Actually it looks to me like it did switch to color at 1:13 but was still so dark it wasnt much benefit..

    @looney2ns thanks for the review. Are you able to set the cam to color mode all the time? When you forced it to color at night in the video above, was the cam light turned on? If not, maybe it can help show a persons' face.

    Thanks @looney2ns

    On another forum a member posted a daytime image from the Lorex version of this camera, and due to the wide FOV lens there is a fisheye effect
    https://slickdeals.net/forums/attachment.php?attachmentid=7812253&d=1547839174

    Would be very nice to see how the OEM version compares ( thus would be useful to have a yard stick or similar straight edge along the sides to see any possible distortion )

    Also would be nice to see how it compares to the newer 8MP cameras and 2MP starlights in day and night time. Perhaps a case of soda or something in the view would be useful to use to compare image quality capture on a stationary image. This way people are able to compare the ability to read the text on the case.

    hmm... maybe they are blocking direct links, see the members post which included the attached photos ( note, the camera image captures are thanks to Soby and are a part of his bench test of the lorex kit )

    You can see some barrel distortion.

    great image quality...how do you feel this cam would be as an upgrade of a 5231 2mp starlight?
