Dahua Pinhole IP da 2MP 2.8mm – telecamera di videosorveglianza IPC-HUM4231S-L4-S3 supporta funzioni intelligenti, come tripwire e intrusione, e fornisce dettagli chiari in ambienti con un forte contrasto di luminosità.
Dahua Pinhole IP da 2MP 2.8mm – telecamera di videosorveglianza IPC-HUM4231S-L4-S3 supporta funzioni intelligenti, come tripwire e intrusione, e fornisce dettagli chiari in ambienti con un forte contrasto di luminosità. L’area chiara e quella scura possono ottenere video nitidi anche in ambienti di forte luminosità o con ombra di retroilluminazione. Dahua IPC-HUM4231S-L4-S3 consente una tolleranza di tensione d’ingresso del ±30% ed è ampiamente applicabile in ambienti esterni con tensione instabile.
La telecamera di videosorveglianza utilizza inoltre una serie di funzionalità avanzate tra cui autenticazione e autorizzazione di sicurezza, protocolli di controllo degli accessi, protezione di fiducia, trasmissione e archiviazione crittografate. Queste tecnologie migliorano la difesa della telecamera contro minacce informatiche esterne e impediscono ai programmi dannosi di accedere al dispositivo.

Great service both online and in person at their Milan office. Perfect for urgent purchases for those who work in Milan in video productions. Highly recommended!
Serious online shop that answered my questions quickly and friendly. Shipping was super fast and the goods matched the description. We recommend. A thousand thanks.
just bought from Martcom, payment via Paypal, package sent via DHL, received in 4 days in France, excellent package, material in new mint conditions and prices super attractive. They have a big stock in Kupo accessories and that’s quite rare in Europe. I recommend Martcom !
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.
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!
Evething was perfect for a fast delivery to Belgium. Communication is easy and fast on what’s app. Thank you.
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.
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!
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 recommend them! Very friendly and professional, they respond quickly to any concerns related to your purchase, or your future purchase!
I recommend! We bought 3 Nanlux 1200C Dyno lamps with shipment to Poland. Very good contact with the store – by e-mail and mobile. Their crew speaks english. Good price, fast shipping abroad. Everything fine! :)
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.
Ho comprato della attrezzatura, spedizione rapida e super puntuale! mi sono trovato davvero molto bene
Absolutely happy I discovered this shop. The team were very responsive on whatsapp and even I hopped on a phone call so they help me a bit with my choices. They were very happy to help and they really know their products. I ordered several profoto products and they helped me make sure they are what I need. I live abroad so they helped me find the lower prices for shipping. I HIGHLY recommend them. As of now I will shop gear with them!
These guys are amazing! Thank you for your job. I got a camera delivered to Cyprus in 2 day – it’s almost unbelievable. Also they are a certified Canon reseller that I had personally confirmed with Canon officials (having bad experience in the past with another online store). Will be coming back for more gear if needed any filming equipment when in Europe 👍.
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.
