Amcrest Plugin for Scrypted

The Amcrest Plugin brings Amcrest-branded cameras, doorbells or NVR devices that are IP-based into Scrypted. Most commonly this plugin is used with 2 plugins: Rebroadcast and HomeKit.

Device must have built-in motion detection (most Amcrest cameras or NVRs have this). If the camera or NVR do not have motion detection, you will have to use a separate plugin or device to achieve this (e.g., opencv, pam-diff, or dummy-switch) and group it to the camera.

Codec Settings for HomeKit

Configure optimal codec settings (as required by HomeKit) using Amcrest configuration (not Scrypted).

You may use the device's webpage access or one of the following applications from Amcrest website: Amcrest Smart Home (mobile), IP Config Software, or Amcrest Surveillance Pro.
NOTE: Amcrest Smart Home app may not expose all codec or stream settings. Use one of the other applications instead.

The optimal/reliable codec settings can be found in the documentation for the Homekit Plugin.

Amcrest Doorbells (e.g. AD110 and AD410)

Specify Type is Doorbell (at top under device Name)
Username admin
Password (see below)
Doorbell Type is Amcrest Doorbell

The admin user account credentials is required to (1) add doorbell to Scrypted or (2) change codec settings with IP Config Software or Amcrest Surveillance Pro applications.

The password for admin username was set when first configuring device (see 2m49s mark of Amcrest setup video).
The admin username credential is not your Amcrest Smart Home (cloud) account that uses an email address for user/login. (Unless you happened used the same password for both.)

Amcrest NVR

Cameras attached or recording through an Amcrest NVR (IP-based) can be used in Amcrest Plugin for Scrypted. Each 'Channel' or (camera) Device attached to the NVR must be configured as separate Device in Amcrest plugin.

NOTE: Snapshots may be inconsistent if using an NVR. A workaround exists if you can access your camera on network without going through NVR (see below Snapshot URL Override). If you can only access your camera through an NVR, then snapshots may not be supported.

IP Address NVR's IP Address
Snapshot URL Override camera's IP address (preferred) or specific port number of NVR for that camera (may work). That is: http://<camera IP address>/cgi-bin/snapshot.cgi or http://<NVR IP address>:<NVR port # for camera>/cgi-bin/snapshot.cgi
Channel Number Override camera's channel number as known to DVR

Troubleshooting

General

Is the URL attempting to use HTTPS? Try disabling HTTPS on the device to see if that resolves issue (do not use self-signed certs).
Does your account (Username) have proper permissions ("Authority" in Amcrest speak)? Try granting all Authority for testing. See below User Account Authority (Camera or NVR).
Amcrest Doorbell: Username is admin and Password is the device/camera password -- not Amcrest Smart Home (Cloud) account password.
Check that you have configured the correct Stream number's codec settings (in Amcrest admin page (Main Stream or Sub Stream(s)).

User Account Authority (Camera or NVR)

If you have a non-admin user account setup on your cameras and/or Amcrest NVR, then the account's access permissions must be sufficient to expose motion events and playback.
