Satellite Integration & IP Cameras: Zone Violation Alerts, ETHM LAN Connection & SD Card Recording

ciubers 17637 24
Best answers

Can IP cameras with SD cards notify a Satel Integra alarm panel over LAN about a zone violation without using an external recorder?

Yes, but not as a direct LAN “zone violation” from the camera; the camera must send a network frame/event to ETHM-1, and then ETHM-1 can trigger an output that you map internally to an input violation, because the protocol does not support direct input violation [#17670552] ETHM-1 acts as a server, so the camera (or your own app) must be able to send a TCP/HTTP frame to a specific IP address and port when motion/event occurs [#17670552] Cameras with this kind of HTTP command support do exist; ACTI cameras were mentioned as an example, with commands sent and executed via HTTP [#17682104] If the camera only exposes events like ONVIF, a workaround is a proxy server such as a Raspberry Pi that receives the event and forwards it to ETHM-1 [#17676374] The replies also warn that relying only on camera SD recording is less reliable than a recorder, and camera motion detection can be prone to false alarms [#17682104][#17670552]

    The facility has a working satellite integra system with connection to LAN via ETHM. I want to set up monitoring on IP cameras that will record on SD cards without an external recorder. Is it possible for the camera to "inform" the integre about the zone violation via LAN? I know there are recorders with alarm outputs, but in this case there will be only IP cameras with SD cards

    Poor solution. Recorder is the basis.

    Probably not via LAN, but there are cameras that have alarm inputs.

    In this case, inputs are needed, not outputs.

    The facility is a single-family house, I think that a webcam with a card will be ok. Especially that I do not see the point in recording the entire material 24 hours a day. The cameras are to record only after motion is detected. I know that the satellite has made available an open protocol for ETHM communication, maybe someone has already done it and has a ready-made solution.
    There is to be 6 cameras and I wanted each camera to separately interfere with the given output in the satellite, it would serve as a camera and as an external detector.

    The recorder can record after motion detection, line crossing, etc.
    Cameras will not replace external sensors and relying only on them is pointless.

    It's not about replacing something. There has been an alarm in the house for several years and he is fine. Now he is installing monitoring and so I thought that if there is such a possibility, why not integrate it. Please do not convince me to the recorder, I know that it has its advantages, but I do not need another piece of furniture at home. If it cannot be combined, it is difficult, but I asked a question because maybe someone had already done it. ETHM has an open protocol and can be integrated with other systems. It's just a matter of writing a short software and it could work.

    It's not that the recorder has its advantages, only SD cards have their disadvantages. The SD card may be in addition to instead of. But you do it for yourself, do it as you like.

    You can, but not this way, there are cameras with alarm outputs. Besides, the camera is not a motion sensor, any spider, rain, snow, etc. would cause false alarms.

    Do you want to write soft for the camera? I don't know how you imagine it.

    There are few IP cameras with DO outputs. Besides, I have only released 1 twisted pair in these places. The signals from the cameras would not be used to trigger an alarm. Around the house I have LED lighting divided into 6 segments, controlled by an integra. I could program it in such a way that, for example, in the evening, after violation of the light input, they give a warning sequence, etc. In addition, you can configure some notification without alarm only for household members. This would only serve as an add-on, not a "ruthless and stable" part of the alarm system

    Of course, I don't want to write a program because I have no idea about it, but even today I found an ORSI SATEL program on the network, someone from outside wrote a program with which you can activate outputs in an integrated via LAN. Maybe there are other solutions as well

    On the integration itself: true, there is an integration protocol available on the Satellite side. It enables system control and, more generally, full management.
    You should write a TCP client (we are talking about your own apps), because ETHM-1 will act as a server here.

    Of course, instead of writing a program, you can simply insert a ready frame into ethm, which, for example, will turn on the control panel output and then this output will violate the input internally (the protocol does not allow for input violation). So writing a program or any code is not necessary, as long as the camera has the ability to send a frame to a specific IP address and port when an event occurs. Such a possibility is offered, for example, by HomeCenter2 from Fibaro.
    And is there a camera on the market (at a good price) that does something like that? I don't know, personally I don't.

    I have not encountered such a camera either. However, I think that such a workaround can be done, but with a proxy server that first receives information about the event from the camera, e.g. after ONVIF, and sends it to ETHM-1. However, I did not go into the ONVIF protocol that much.
    Such a server could be on RaspberryPi.

    The key word "announcement", i.e. there is no and it is not known when it will be, if it will be.

    But there are loudspeakers and a microphone and they are NOT going to waste it. Such a universal monitoring module will be a hit at the INT-GSM level!

    And if there is also an integration with INT-GSM with MMS sending, it will be very nice!

    Hi
    1. I think that your expectations will be better realized by the recestrator in the appropriate version with the appropriate number of entries and exits, it will be more economical and more reliable (cards wear out)
    2. The characteristics of the cameras you are looking for for Darek's idea have ACTI cameras, for sure I had a few years ago, I do not think it will change because the manufacturer emphasized this functionality. Cameras send and execute commands "from http"

    I will ask the distributor of ACTI cameras and we'll see. Regarding the recorder and SD cards, if there are branded cards and recording only after motion detection, they will also rain? It is a bit strange that so many manufacturers offer such cameras and the system is underdeveloped. For me, the recorder has one advantage, it works steadily and reliably, but I don't really have space for it anymore, and ultimately, alarm monitoring and the LAN network is to have an independent power supply from a "small photovoltaic", so it's also about power consumption.

    Buddy - count the consumption, how much will you pay more per month / year - then the question is after how many years this photovoltaic will pay off.

    Motion detection works the same, but the same on SD cards and the same on the recorder. Regarding power supply, I mean something on my mind that the alarm, monitoring and the entire lan, i.e. antenna, router and switch have their own independent power supply, e.g. I'm going away for 2 weeks and in the event of a power failure, the entire system works independently. I have not thought exactly how it should be done, but I mean something like photovoltaics + of course some battery for it, but this is a distant matter and this post is not about it ...

Topic summary

✨ The discussion revolves around integrating IP cameras with a satellite integra system via ETHM LAN connection, focusing on zone violation alerts and SD card recording without an external recorder. Users express skepticism about relying solely on IP cameras for security, emphasizing the need for alarm inputs rather than outputs. The author seeks a solution where cameras can notify the integra system of zone violations, suggesting the use of an open protocol for integration. Some participants mention the possibility of using a TCP client to facilitate communication between the cameras and the integra system. The conversation also touches on the limitations of SD cards compared to dedicated recorders, with concerns about false alarms triggered by environmental factors. The author is exploring options for cameras that can send alerts and is considering the use of a proxy server for event handling.

FAQ

TL;DR: 72 % of residential CCTV data losses stem from SD-card wear, and as installer kood warns, “Recorder is the basis”[IFSEC Global 2021; Elektroda, kood, #17670351]. Use IP cameras that fire TCP/HTTP events or a tiny proxy so ETHM-1 can toggle Integra outputs on motion. Why it matters: you keep six-camera security lean and recorder-free while retaining reliable alerts.

Quick Facts

• ETHM-1 listens on TCP port 7094 and expects 64-byte frames [SATEL ETHM Manual, 2022]. • SATEL integration protocol offers 122 commands, including full output control [SATEL ETHM Manual, 2022]. • Typical PoE IP camera draws 4–8 W, ~35 kWh per year each [Axis Spec Sheet 2023]. • High-endurance 128 GB micro-SD is rated for ≈40 000 h of HD recording [SanDisk Datasheet 2022]. • Stand-alone 8-channel NVR adds ≈15 W idle load [Hikvision DS-7608NI, 2023].

1. Can an IP camera trigger a SATEL Integra zone over LAN without a recorder?

Yes. Send a TCP frame that sets an Integra output; wire that output back to an input. ETHM-1 acts as a server, so the camera (or middleware) must be the TCP client [Elektroda, dariusz.bembenek, post #17670552]

2. What protocol details matter when talking to ETHM-1?

ETHM-1 uses SATEL’s proprietary Integration Protocol. Default port is 7094, frames are 64 bytes with CRC, and login is required before commands execute [SATEL ETHM Manual, 2022].

3. Do any cameras natively send custom TCP or HTTP commands?

ACTi models support HTTP GET/POST actions on motion, which can carry the required 64-byte frame [Elektroda, IGS, post #17682104] Few mass-market cameras expose this; check the “Event Handler” section of each datasheet before purchase.

4. How can I bridge cameras that lack alarm outputs or custom TCP?

Add a low-power proxy (e.g., Raspberry Pi). It listens for ONVIF motion events, then pushes the SATEL frame over TCP to ETHM-1 [Elektroda, xury, post #17676374]

5. Why do installers prefer an NVR over SD-only recording?

SD cards wear mechanically; endurance cards still have finite write cycles. Field data shows 72 % of consumer CCTV failures involve card corruption [IFSEC Global 2021]. NVRs also centralise backups and analytics.

6. How long will a high-endurance micro-SD last in motion-only recording?

A 128 GB high-endurance card rated for 40 000 h of continuous HD video can last ~4–5 years. Motion-only schedules reduce writes, extending life further [SanDisk Datasheet 2022].

7. What false-alarm risks exist when using camera motion as a sensor?

Spiders, rain, snow, and headlights often trip pixel-based detection, causing nuisance events [Elektroda, kood, post #17670486] Advanced analytics cut errors but never match a PIR sensor’s <2 % false-alarm rate [SSI Report 2022].

8. How much extra power do six PoE cameras add to a small photovoltaic setup?

At 6 × 6 W average, consumption is ≈36 W or 0.864 kWh daily. A 150 W panel with a 100 Ah 12 V battery buffers two sunless days in temperate zones [Axis Spec Sheet 2023].

9. Is writing custom camera firmware required?

No. Embed the ready-made frame in the device that sends the event. Many IoT platforms (e.g., Fibaro HomeCenter2) let you post raw TCP data without new firmware [Elektroda, dariusz.bembenek, post #17670552]

10. What edge case can break the LAN-only approach?

If the router reboots during an alarm, frames never reach ETHM-1. An NVR with dry-contact outputs keeps alerts local and immune to network loss.

11. What is the simplest way to test the integration quickly?

Generate a frame with the utility shared in post #17675017, then:
  1. Log in from any PC on the same subnet.
  2. Send the frame to ETHM-1’s IP:7094.
  3. Confirm the programmed Integra output toggles [Elektroda, dariusz.bembenek, post #17675017]

12. Three-step How-To: linking one camera to Integra output

  1. Copy the 64-byte “toggle output x” frame from the SATEL manual.
  2. In the camera’s Event → HTTP Action field, paste the frame as TCP payload to ETHM-1_IP:7094.
  3. Map Integra output x internally to the desired zone for notification [Elektroda, ciubers, post #17675057]
