    Mic in RCA jack on Dahua NVR?

    I have one camera that does not have a built in microphone. So I connected an external mic to the "Mic in" RCA jack on the back of my NVR (Dahua NVR5208-4KS2 from Andy). My problem is, how do I have that mic apply to the feed of the mic-less camera? I went to Camera/"Encode", then More, but I...

    Gain or exposure compensation better?

    I'm still working on dialing in my SD49425XB-HNR PTZ after a few years. I can't seem to find the balance between avoiding motion ghosting, avoiding too much noise, and being able to see a little bit of beyond the sidewalk. I have three pretty big IR projectors covering the width of the sidewalk...

    Android DMSS very slow loading and PTZ

    On the latest android DMSS version 1.99.0000, the playback loading became unusable without any changes at all to my home network or cameras. I uninstalled and installed 1.98.0002 and still had somewhat slow playback loading, so I uninstalled and installed 1.98.0000 and playback speed got a bit...

    Missing second in NVR playback

    I'm stumped. When I review playback on my NVR ( NVR5208-4KS2) for my LPR (IPC-B5442E-Z4E), I click next frame button one click at a time to see frame by frame and look at the license plates. I am playing back directly on the NVR with connected monitor, not via phone or PC app. The problem is...

    Http post to change to ptz preset?

    I think I've heard that there is an ability to use a http url to switch to ptz presets? Any idea the correct full url and variables for that action? I'm thinking of having my local network zwave hub do a http post? curl? action upon a trigger (e.g., door sensor opened). SD59225U-HNI

    Catching moving cars by IVS

    I have tried trip lines zig zagged and intrusion boxes for my LPR, but the IVS only catches the last bit of cars going any speed. Has anyone had success with a scene like this? LPR is perfect, just prefer to be able to review by IVS events versus all footage to look for cars.

    Very inconsistent ivs on new PTZ

    Hi all, I'm having a weird issue where my new SD49425XB-HNR ptz is being very inconsistent with logging IVS (and then doing related auto track). For hours it just won't register a single IVS event and then other times it will auto track every passing person and log the IVS events without issue...

    Help with alarm in pigtail wire

    I'm connecting a PIR motion sensor to new PTZ and am wondering how to best connect the relay wires to the small wires on the pigtail. Twist the wires and then electrical tape down the wire insulation a few inches? I've done this in the past, but it creates an upside-down V shape that isn't very...

    Weird PTZ mounting location help

    Looking for advice. I want to mount my new PTZ under a front porch so pretty much only the actual camera portion (black in color) is visible from the street. As shown in the photos, the wood beams are slightly shorter than the ptz mount screw holes. What would you do? Just big bolts in the...

    Blurry before sun down and big chunks of IVS yellow

    Two odd issues that came up out of nowhere. HDW5231R-ZE 1) I schedule switch to night and start it an hour or two before sunset because things don't look great in color when this east facing camera has low light. Recently the focus has been horrible for an hour or so after switching to night...

    How to get cables into house from trench?

    I'm thinking about running some burial cable in the ground, but I'm not sure how people get the cables into the house. Could you help share some photos of how your cables get into your house from the ground trench? My other cameras are under the soffit, so go right into the attic. I'm trying...

    Few random days no IVS events logged on PTZ

    A couple times now I've checked on the NVR itself and from gDMSS app and for a day or two there are absolutely no smart recording IVS intrusion events. Then the next day without any change to settings IVS intrusion events are on the timeline for weeks into the future without issue. The PTZ 24/7...

    Opinions on night footage

    I'm using a IPC-HDW5231R-ZE from Andy from maybe 15 feet from the front path. I've also got a cmir110 plus a small circular cm vision infrared pointed down the front path in the lower left of the frame on the front porch. Settings are on shutter priority range 0-1ms and around 15 for HLC due...

    Thoughts on sidewalk angle

    Thinking about adding a LPR cam at the edge of my property right at the sidewalk. See photo where I would install the camera on a short pole. Could this angle work to hit the spot with the red X? Photo taken was 4mm.

    Over or under or side of light?

    I want to mount a Dahua IPC-HDW5231R-ZE to the stucco, but should I put it over the light, under the light, or to the side of the light? The light is closed on the top, but completely open on the bottom and glass on the sides. They will usually be off, but don't want to mess up camera view if...
