@user_736098558853348_736098558853348 It's unusual. Some people don't insert correctly the c-type plug into the socket on the camera. One has to push a bit. If you encounter the same issue and while still under warranty then I suggest you to email support on support @ reolink.com.

@user_914458500501648_914458500501648 Correct. Applies to most Windows applications.

@user_603788725944329_603788725944329 The DUO 2 cams (don't know on DUO 3) don't have WIFI band preference and since you have one SSID for both 2.4G and 5G the cam tries to connect to anyone with strong signal. Can you create different SSIDs for 2.4G and 5G? 2.4G has longer range as it has longer wavelength.

@smiles_891607800037615 The official article code is the one indicated in their site. Only from 3rd party they have these codes which are confusing. So every 6 months or so email support to check whether there is any newer fw.

@big_ted you can check the data package associated with the SIM by entering to the SIM service on the cloud tab.

@flashmagnum I am on Android client version 4.52 and when the icon shows one box then when you click on the camera you get the wide-screen view only. You need to swipe to the left to get the telephoto view.

@big_ted Nobody is asking anymore for the Windows version. More customers are using the Android/IoS and 3rd party applications like HA, BI, etc. Even Reolink are not updating their Win and Mac clients.

@smiles_891607800037615 You bought this cam from 3rd party and so better to email support citing your hw build and fw version. For sure I saw someone updated this to DB_566128M5MP_P.3215_2404072241.D340P.OV05A10.5MP.REOLINK. Email them on support @ reolink . com

@big_ted So you are always ahead of us. But the SIM provided is for 365 days and then you have to top it.

@big_ted If I recall correctly you have been provided with a 4G TrackMix. So if the SIM was installed then you have top it up through Reolink account which has been added to the Android/IoS client. They offer 365 days 24G data plan.

@big_ted If you use their SIM then you need to roam over a local mobile operator with whom they have agreement. So customers have to buy a data package from Reolink. Reolink will have various operators offering SIM data services eg.. 1 in EU to cover EU countries which have roaming like at home.

@chopstix I have moved from software development to senior technical architect to teaching and now consultant on security (not cameras :)). 1992... at that time there was pascal and C.

@chopstix Even in Europe. So what were you programming in? C++, Assembly, python ? I am a programmer too and mainly use C++ and Assembly in my applications. It's fun.

@chopstix
It couldn't be a local eSIM as local mobile operators won't allow it. So it has to be an operator who has roaming agreement with all mobile operators. Then the MCC + MNC of the IMSI will be mapped to a Global Title and MAP messages forwarded to the serving operator. Charging will be handled by this operator.

Note that in the description it is stated that the SIM is included. So we are there.... similar to the P2P servers provided by AWS.

@chopstix I used to design, implement and carry out the acceptance testing of mobile networks :). I know to what you were referring to but as I explained an IMSI (i.e. Physical SIM) consists of 16 digits, the first 5-6 are the MCC and MNC . The MCC is the mobile country code which is 222 for Italy (like the Telephone country code +39) and MNC is the Mobile Network code, namely, the operator. eg 299 1mobile, 08 fast web, etc. So each operator will only authenticate the IMSI range assigned to him by the local Communication Authority. So to connect to different networks one needs to have different SIMs. Note that I am excluding MVNOs which are operators which use the mobile infrastructure of another operator. These MVNOs normally use different IMSI range. So to connect to two distinct mobile operators, you need two SIMs.

The two way radio units you mentioned still use SIMs. These use packet data only. Most operators assigned these units M2M SIMs. Any device which connects to 4G networks requires a SIM. The only exception is when calling the emergency number in which case there is no IMSI authentication. Some people remove the IMSI and make a prank call to the emergency service. They think that they cannot be traced. They are stupid as the operator has the IMEI of the phone through which the call has been made.

Let see with what they come out.

@thierry_835077729128592 Oui, vous avez besoin de l'IP ou de l'UID. Je formaterais la SD et vérifierais que la caméra fonctionne correctement avant de la connecter au Home Hub. Faites tous vos tests avant de l'installer. Prenez le temps de vous familiariser. Connectez-le ensuite au Home Hub et c'est le seul moyen d'accéder à la caméra. Uniquement via le hub domestique. Nous avons également demandé un accès direct mais nous n'avons reçu aucun retour.

@flashmagnum_909351053578484 I suggest you to submit your request to support on support @ reolink . com. We are customers like you assisting members wherever possible based on our skills and experience.

Note that when I see them separately, it is the same as the RLC-811WA, E1 OD Pro, Argus 3 Ultra, etc.

@chopstix Let me give some details on SIM.

Every mobile operator orders SIM cards from SIM manufacturers. Each SIM comprises an identifier ICCID, IMSI and the authentication key Ki amongst other parameters and applets. 

The Integrated Circuit Card Identifier (ICCID), an identifier of the actual SIM card chip itself. ICCIDs are also used to identify embedded SIM (eSIM) profiles. This ID can be up to 23 digits long, including a check digit calculated using the Luhn algorithm.

The International Mobile Subscriber Identity (IMSI) identifies SIM cards uniquely by their individual operator in a cellular network. The IMSI is stored as a 64-bit field and is communicated to the connected cellular network. In the core of a mobile operator network, the IMSI is used as main identification for obtaining further customer and device specific data.

All SIM cards contain cryptographic keys. The secret authentication key called Ki is unique and is stored on the ROM, a protected area of the SIM. The Ki is never exchanged between the mobile device and the network. Its purpose is to derive sub-keys that perform the necessary authentication procedures when a mobile device tries to join a carrier’s network. The Ki is also stored on the carrier’s network within a component called the Home Location Register HLR or lately with the introduction of 4G and IMS this is being referred to Home Subscriber Subsystem (HSS). The Ki is only known by the SIM manufacturer and a few persons handling the HLR programming. The IMSI and the Ki have to be inserted in each subscription.

So when you switch on the camera or smartphone, there is the IMSI attach whereby the mobile will forward the IMSI to the Radio access network (BTS for 2G, NodeB for 3G, eNodeB for 4G) and from the RAN to the MSC (for calls) and SGSN (3G data) or MME (4G data). This IMSI attach message will end up in the HLR which shall authenticate the SIM. So if the IMSI is defined on the HSS then the IMSI attach procedure will continue otherwise it will be rejected. And an IMSI can only belong to a mobile operator. Thence to connect to another mobile operator you need another SIM card which has different IMSI identifier. The MCC is the same but the MNC and SN will be different.

I hope that Reolink should start to add eSIM where there is no longer the need of any physical SIM. This innovation offers the same functionality as a regular SIM card but with an added unique capability: it is programmable, allowing for enhanced flexibility and ease of use. This programmability empowers users to seamlessly switch network operators without needing to physically swap cards. You just buy a plan and they will ask you to scan a QR code and then enter some details the details (like apn)

Now a GSM module integrated on smartphone or any device to be connected to GSM network is continuously checking the power of adjacent cells. If the calculated power is better that the one being connected to, the module shall request a location update to the mobile RAN with the new cellid it wishes to connect to. It could be a 3G cell rather than 4G depending of the module is allowed to anchor to 3G (UTRAN) networks. It could be that the mobile is on the edge of an area and it will be continuously changing LAC/RAC/TAC.

So I guess that in their previous 4G cameras, the GSM module was not able to compare the power of adjacent cells and request a LUP.

I know this area quite well :). And now there is VOLTE which requires IMS.

@user_817261050261638_817261050261638

Most probably you purchased the 3W solar panel. I have the 6W solar panel with the Reolink DUO 2, Argus 3 Pro and Ultra, Argus 4 Pro and have no issues as long as there is 2 hours of direct sunlight. On the Argus 4 Pro I get around 2 hours of battery usage per day.

But yes I agree that they should provide higher wattage solar panels esp in places with short periods of direct sun and higher capacity batteries (like the Altas PT ultra).

Nevertheless you did a good job. Well done. I don't ask any question as I know all the theory :).

@ddelrosso_61389620748490 That's it.
