    VTO2111D-P-S2 not ringing on phone when connected to NVR DHI-NVR4108-P-4KS2

    On a typical Dahua POE equipped NVR, if the doorbell is connected to the built-in POE ports the doorbell (and cameras) will be isolated from your LAN. That is to say, the POE devices will be on an entirely different IP subnet. This configuration blocks them from the router. One workaround is to...

    Noob here. Needing help picking a camera

    There's more to the equation than that. First, 650 Mbps is likely your download speed. Upload bandwidth is generally much smaller. For example, my Comcast plan is 200Mbps download, 5Mbps upload. And even worse, some ISP (like mine) impose a monthly data cap; exceed the monthly limit and my ISP...

    DSC alarm system with PC1555RKZ keypad wanting a display

    My DSC PC5010/POWER832 system has the LCD5500Z and three other keypads. But it's been fifteen years since I installed the system. I recall that the Keypads will require some programming to enroll the new configuration (such as partition slot and function key assignments). You will also have to...

    Smart Motion Detection (SMD) and Video Detection Region

    Too bad the solution requires privacy masking to omit regions from the SMD detection area. Blacking out useful image area seems like a high price to pay. - Thomas

    Dahua NVR and Wifi Option

    Perhaps try a WiFi Extender module that has a built-in LAN port. Although these are normally intended to improve WiFi coverage, the local LAN port feature that some include would give you a place to plug-in the NVR's network cable. For example, I have a TP Link Router and a few months ago I...

    Pixelated Footage

    Last year I experienced unusual pixelation on a Dahua camera that somehow had its ROI (region of interest) turned on. So check each camera and confirm this function is disabled. The ROI setting is in the camera's Video setup page. - Thomas

    Amcrest AD110 - Button Push Event - An Unsolved Mystery

    Nice. If you don't mind, please come back and share how you implemented your doorbell event detection. I'm interested in using a ESP32 or ESP8266 to receive the doorbell press events. Maybe your solution will assist my coding journey. - Thomas

    Basics of Automation !

    Good list above. One thing I'd add is a CAT5E/CAT6 run from the network closet to the doorbell button (for a POE doorbell camera). - Thomas

    Dahua Visit

    I've been meaning to do that using ESPEasy, which is open source firmware that runs on inexpensive ($10) ESP8266 and ESP32 WiFi devices. https://github.com/letscontrolit/ESPEasy ESPEasy has sunrise/sunset variables and a text based rule engine that can send http commands. So a single ESPEasy...

    Latest firmware for NVR5216-4KS2 hardware version 1.0 ?

    The V4.001.0000003.2 bin was found in EmpireTecAndy's discussion: DH_NVR5XXX-4KS2_MultiLang_V4.001.0000003.1.R.200813 Google tells me that it is also here: Index of /images/Files/Firmware - Thomas

    Latest firmware for NVR5216-4KS2 hardware version 1.0 ?

    I have a NVR5216-16P-4KS2 (hardware V1.0). A couple weeks ago I did a firmware upgrade and updated its V3 firmware to what I believe is the latest V4. BTW, there's a couple of older discussions on the forum regarding NVR5216 firmware upgrades. Using the general information learned in them, I...

    Need Advice on IPC-HDBW4231F-E2-M Dual Starlight Cam IVS Settings

    That's unfortunate news. Too bad the data sheets don't mention this; would have prevented me from choosing the 2MP camera. - Thomas

    Need Advice on IPC-HDBW4231F-E2-M Dual Starlight Cam IVS Settings

    I have a Dahua IPC-HDBW4231F-E2-M 2MP "Boobie" (dual sensor) camera that I bought from Andy's recent refurb sale. I'm using it on a Dahua NVR5216-16P-4KS2. Installation was hassle-free and both camera views are visible. My plan is to use it at the front door. One image sensor will look forward...

    POE CAT6 Tests OK Yet No Camera Connectivity

    I'd say the POE tester is reporting "Non-Standard!" because of the low wattage (9W) measurement. Standard POE is typically 15W and should not be less that 12W on longer runs. If the tester is accurate then either the cable has deteriorated or the POE Switch's port is in trouble. For...

    Camera recommendations for location

    Can't go wrong with a T5442 ZE. But you only care to observe and so it will be a bit overdressed for the occasion. It seems to me that this installation deserves a good budget 2MP 3.6mm Starlight. Now you can use the T5442 in a more critical location.

    Is there a way to create dynamic overlay text based on a text file or similar?

    Dahua, Amcrest, and some other IP branded cameras have an HTTP API that allows writing text overlays directly to the camera image. Here is an example for Dahua / Amcrest cams (tested on a Amcrest IP5M-T1179EW): Turn on the overlay feature for the camera at 192.168.1.240...

    Basic Indoor camera

    +1. The Amcrest IP2M-841 (see link above) has been a popular recommendation for basic indoor installations. I have a feeling that this choice will satisfy your daughter's dog watching requirements. Not a user yet, but I ordered one yesterday. Alexa just announced that it will be arriving today...

    Cameras rebooting when nvr is connected to router

    The symptom suggests that this might be an IP address conflict. Have you confirmed that your router's network is not already using ANY of the IP's needed by the camera system? - Thomas

    How to improve upon constant (false) motion detection from cameras?

    Regarding an Amcrest IP5M-T1179EW running Dahua firmware, the added IVS feature allows for tripwire and intrusion. It does not provide any other AI functions such as human or vehicle detection. Keep in mind that it is a $60 5MP camera, so it does not have the computational horsepower to do AI...

    How to improve upon constant (false) motion detection from cameras?

    Yes, that about sums it up. IVS tripwire and intrusion are fantastic. You can add it to your Amcrest IP5M-T1179EW by installing Dahua firmware. Search the forum for the magic instructions. - Thomas

    Need Advice: 2.8mm or 3.6mm at front door?

    @looney2ns, thanks for the links and camera recommendations. Face detection is important to me, which is missing on those cameras. Front door visitor photos get emailed to me and I like seeing the head shots. I ordered the camera this morning. Instead of the IPC-HDBW4431F-AS I bought a...

    Amcrest 5MP POE Security Camera System

    You're asking the big question at a site with many serious security camera members. So consumer boxed systems are rarely (if ever) recommended. But you stated this: So I'm breaking from the mainstream advice. Given what I saw at the Sannce web store, I believe you will be very satisfied with...

    Need Advice: 2.8mm or 3.6mm at front door?

    Thanks for the advice. Great to hear that 2.8mm is a good choice. That's what I will use. Seeing packages at the door threshold is not critical for me, but I can add it. Perhaps a ceiling camera or a turret on a side wall looking at the door. I have a IPC-T2431T-AS for the front walkway and a...

    Need Advice: 2.8mm or 3.6mm at front door?

    I don't see a close focal spec. Just the usual DORI stuff. Here's the datasheet: https://www.dahuasecurity.com/asset/upload/product/20180816/DH-IPC-HDBW4431F-AS_Datasheet_20180816.pdf BTW, it has smart IR to reduce those close-up face bloom situations. But the area will be well-lighted so I'll...

    Need Advice: 2.8mm or 3.6mm at front door?

    I plan to install a Dahua IPC-HDBW4431F-AS mini-wedge dome at my front door. I prefer this camera's small profile and I will be using its face detection as the IVS event to trigger when a person is at the door. The camera will be 5.5 to 6 ft AFF. The front door's porch area is a short...
