Dahua Pinhole IP da 4MP 2.8mm – telecamera di videosorveglianza IPC-HUM4431S-L5 è ampiamente utilizzata in contesti nascosti o in ambienti di piccole dimensioni, come banche o schermi pubblicitari. Questa telecamera pinhole offre un’efficienza di codifica più elevata rispetto a H.265 e H.264, oltre a fornire video di alta qualità e ridurre i costi di archiviazione e trasmissione.
Grazie alle avanzate funzioni di elaborazione delle immagini e alle ottiche utilizzate, la tecnologia Dahua Starlight è in grado di fornire video chiari e colorati anche in ambienti con scarsa illuminazione. Dahua IPC-HUM4431S-L5 utilizza una serie di tecnologie di sicurezza tra cui autenticazione e autorizzazione di sicurezza, protocolli di controllo degli accessi, protezione sicura, trasmissione e archiviazione crittografate. Queste funzioni migliorano la difesa della telecamera contro minacce informatiche esterne e impediscono ai programmi sospetti di accedere al dispositivo.

I stumbled upon Martcom because they offered the lowest price on an item I was looking to purchase, but I will definitely buy again from them because of the EXCELLENT customer experience I had communicating with them. They really went beyond my expectation of good service.
Immediately very kind and available for any clarification. Competent and professional from every point of view, ready to advise and help, to remove any doubts about the use or choice of the equipment you need. I will definitely come back to buy in the store from them or if necessary to rent.
Professionalism and availability on the supply of photographic equipment for professionals! Thanks from Nice Shot Art studio !!
The Martcom team was super efficient, the service was very fast, and when asking them about the field they clarified any doubts I could have. Totally recommended.
I’ve made purchase from this company a couple of times and found them to be highly reliable, well priced and stocked and easy to contact. Their ‘chat now’ really works (so many web sites offer this, only to disappoint) and the responses are fast and full, so need need to keep going back. I think this is a very good company, with a great catalogue of quality gear (esp their range of Kupo products) and so much of it seems to be in stock which is often not the case, especially here in the UK where since leaving the EU (regrettably) we seem to be suffering huge stock delays. So I am happy to recommend Martcom.
What i ordered came really fast and the whole process was smooth and easy. I will definitely buy again and again from these guys.
Very well assorted stock of items related to photo and video. Reasonly low priced. God my Smallrig 55′ parabolic defuser very fast delivered to northern Norway. Carefully packed and no damage. I just found this internet store, Martcom, and I think they can match BHPhoto(US) and EU stores in good service and reability. I’ll be back!
Negozio online serio che ha risposto in modo rapido e amichevole alle mie domande. La spedizione è stata super veloce e la merce corrispondeva alla descrizione. Noi raccomandiamo. Grazie mille.
A pleasure to do business with. Was looking for Canon R7 and Martcom was the only place I could find it in stock. Very competitive price, and communication with the company was excellent throughout the process. Delivery 3 days earlier than expected. Would recommend Martcom and would definitely use again.
This is a great store: large stock of professional gear, good prices, prompt communication via email / WhatsApp. The dispatch of the order was speedy, and the item arrived super quick in a well-thought packaging. All in all, a warmly recommended new young store, standing out for its remarkable service. Keep up the good work!
Excellent service in relation to my recent order and especially the prompt and efficient communication relating to the delivery of the items which were subject to a strict timetable. I would highly recommend Martcom.
Franchement au top, envoi le jour même, package au top, matériel nickel en bref achetez les yeux fermés (et ça a été livré ultra vite)
It was the first time making a purchase at Martcom, the process was smooth, cameras arrived in proper packing and delivery was quick to Portugal. Thank you for the support on the chat before the purchase. Recommended 100%.
Falsely advertised free shipping for over 500 Euro spend as it says at the top of home page. Placed a large order, no shipping cost added (free) then next day receive an email asking for 420 Euro shipping fee to Cyprus also in EU. Despite highlighting their misleading terms and conditions to them they refused to send the goods. Would not recommend this company as they don’t honour the contract of sale but make excuses after buyer pays.
It was my first order at Martcom and I was a little afraid, but the order arrived quickly and at a much better price than at other stores. Although it was a problem with a missing product, the problem was solved by email within a few hours, and the missing product was sent with the fastest DHL shipment. Thanks for the seriousness and I will be back with other orders soon. I highly recommend!
