Dahua Pinhole IP 2MP 2.8mm – video surveillance camera IPC-HUM4231S-L4-S3 supports intelligent functions, such as tripwire and intrusion, and provides clear details in high contrast brightness environments. The light and dark area can achieve sharp video even in high brightness or backlight shadow environments. Dahua IPC-HUM4231S-L4-S3 allows ±30% input voltage tolerance and is widely applicable in outdoor environments with unstable voltage.
The video surveillance camera also uses a number of advanced features including security authentication and authorization, access control protocols, trust protection, and encrypted transmission and storage. These technologies improve the camera’s defense against external cyber threats and prevent malicious programs from accessing the device.

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.
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.
Ho acquistato da Martcom un treppiede e relativa testa fluida che con la scontistica offerta sul sito mi sono sembrati davvero convenienti. Spedizione rapidissima nonostante il periodo e imballo perfetto, consiglio vivamente!
ho comprato da questo sito già un paio di volte negli ultimi mesi e mi sono trovato benissimo… prodotti di alta qualità, spedizione veloce e prezzi ok
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.
I recommend them! Very friendly and professional, they respond quickly to any concerns related to your purchase, or your future purchase!
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!
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.
Ho acquistato nei giorni scorsi una fotocamera e non posso che esprimere un parere favorevole sia per l’assistenza durante l’acquisto che per la serietà professionale e la gentilezza del personale.
Ottimo store e fantastica comunicazione diretta con il cliente, persone affidabili che vengono incontro alle tue esigenze. Top!
