Alarm Server on Hikvision ANPR 2026

[shaunj187za]

I have two new LPR cameras, and I am experiencing issues with both:

1. iDS-2CD7A46G2/P-IZHS
2. iDS-TCM403-BI

(For reference, we have many H3, H7, and H8 units that have been using the alarm server function perfectly for years.)

1. iDS-2CD7A46G2/P-IZHS (2025)​

I currently have a 2025 iDS-2CD7A46G2/P-IZHS installed.


However, the camera continuously misses the last digit of the license plate in either lane. I have experienced this issue before, and a simple firmware update usually resolves it.


The camera was shipped with firmware version V5.9.10 build 241218. I have since upgraded it via the portal to V5.9.23_251223.


The firmware upgrade resolved the incorrect plate reading issue. However, it immediately broke the alarm server configuration.


I am not sure if you are familiar with RequestCatcher, but I have configured it as an additional alarm server. The camera is not posting any data.


By chance, I have been able to get the alarm server to send alerts, but only if I specify either “License Plate” or “Vehicle.” In these cases, it posts one image corresponding to the selected option.


However, when I select both “License Plate” and “Vehicle,” the camera stops sending alerts altogether.


Please advise.

2. iDS-TCM403-BI (2025)​

With the 2025 iDS-TCM403-BI, I am unable to get it to post to the alarm server at all.


Do you have any experience with this model or guidance on configuring it correctly?

I don't have any experience with the more expensive ones like iDS-TCM403-BI

I only have 3 types on the sites I manage:

Very old now: DS-2CD4A26FWD-IZS/P (R3)

From around 2020: DS-2CD7A26G0/P-IZS (H3)

From around 2024: iDS-2CD7A26G0/P-IZHSY (H8)

The old R3 firmware ones are on what I believe to be end of life V5.4.5 170731
These have always missed the FIRST digit ot of "a lot" of UK plates. It's strange, some plates it always reads correctly and others it always misses the first digit.

The other H3 (V5.6.10 220924) and H8 (V5.7.8.0 230712 or V5.8.50 240806) don't have the missing digit bug.


But sorry, I can't help with any alarm server questions - I have never used the HikVision black/white list or alarm server. I use a custom home made system where all ANPR data/photos go into a MySQL database and from there I can do watever searching/monitoring/reporting/alerting I want. I can even mitigate the missing digit bug for plates that are seen regularly as I have a "common mis-read of" field in the database which then corrects those mis-reads going forward.

Greetings,

1. I have not yet worked with G2 ANPR this is H11 i believe. But what can be done is that you set my alarm server and i check if i get anything.

Quote(I am not sure if you are familiar with RequestCatcher, but I have configured it as an additional alarm server. The camera is not posting any data.)

Im not sure what you are refferecing with RequestCatcher here, care to elaborate? I only used 2 methods. 1 is HTTPListener and other method was POST polling via ISAPI node.


2. This model worked fine, i have attached raw output from data i received

Configuration:

@trempa92 That Image you submitted looks like the interface on a TCM? I will need your help with my iDS-TCM403-BI

. i updated to the LATEST firmware and still get nothing... Firmware_V5.4.4_251216​

192.168.2.107 that is your local ip?

FYI: Request Catcher is a free online debugging tool that provides a temporary subdomain (e.g.myproject.requestcatcher.com) to catch, inspect, and analyze incoming HTTP requests and webhooks in real-time. It is commonly used by developers to test API calls, troubleshoot webhook payloads, and visualize data sent by external services without setting up a local server.

 

[trempa92]

Yes that was my local ip for testing purposes

Image i submitted is indeed web interface of TCM camera. Unfortunately i do not recall on what firmware test was done. But it as newest during that time and i tested it this year January.


Perhaps RequestCatcher is not sending respond bytes to camera, hence no flow. If ANR is enabled, the data will loop until you send respond 200Ok(). Cant really speak as i never used that myself. I have my own server and local testing enviroment set. So i dont need such tools.

This is cloud solution by polling, So app can be anywhere and device doesnt need port forawarding. Simply connect to HikConnect or HikPartnerPro and thats it. I use both Hik cloud SDK's

Currently im just seeing a RED X as your reply.....

Yea same as well, seems there was image purge or bug, neither of other threads have images

With the help of @trempa92, we found out that both the H11 & TCM's Alarm server functions was working and sending out the data the entire time.
HOWEVER the newer firmware is sending the data differently compared to how it does on the H3, H7 & H8's..

"The newer Hikvision Alert Notification sends the entire xml to the server as a record in one of our columns, it had an issue committing the record because the xml exceeded the field size for that column we resolved that issue because that field and column wasn’t needed but it would throw an errror when trying to commit the record "
