Dahua Bullet IP 4MP 3.6mm – video surveillance camera IPC-HFW2431S-S-S2 adopts the latest Starlight technology and displays better color images in low light
With an advanced video algorithm, Dahua IVS technology supports smart functions such as tripwire and intrusion. Dahua IPC-HFW2431S-S-S2 is equipped with a series of core security technologies, such as security authentication and authorization, access control, trust protection, and encrypted transmission encryption, which improve data protection and prevent malicious programs from hacking the device.
The camera exceeds a series of rigorous dust and humidity tests. It has a dust-proof function, and the housing can function normally even after being submerged in water at a depth of 1 m for 30 minutes. The camera allows ±30% input voltage tolerance and finds wide application in outdoor environments with unstable voltage. Also available in black finish on request.

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 👍.
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!
Muchísima variedad de artículos para el mundo audiovisual y con grandes ofertas. En mi caso compré un softbox de Smallrig (Artículo que al día de hoy no es fácil conseguir en stock) a un precio muy competitivo. Muy contento por mi compra. He tenido algunas complicaciones con la entrega de mi paquete por culpa de la compañía DPD Spain (SEUR) en Málaga, la cual, si vivís en España, no recomiendo en absoluto. Un punto a destacar muy importante, el paquete vino bien protegido. En mi caso particular, mi paquete, en las esquinas le añadieron un protector rígido muy robusto, lo cual es un extra que ayuda con la protección del paquete ante la manipulación de los transportistas. El servicio al cliente es excelente. Los chicos dan respuesta muy muy rápida y te ayudan ante cualquier duda. Eso como cliente, lo valoro muchísimo y considero que tiene mucho peso al realizar compras online. Realmente lo aprecio. Yo me comuniqué mediante WhatsApp. La web es muy intuitiva y fácil de navegar, lo cual me gusta mucho. Si no hablas Italiano (mi caso) tienes la opción de navegar por la web en inglés, por lo tanto, es sencillo de entender. Definitivamente, volveré a comprar, pero asegurándome de no seleccionar DPD Spain (SEUR) para el envío a España. Mi valoración es 5/5. Repito, EXCELENTE CUSTOMER SERVICE 👏🏻
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.
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.
ordered a hard to get canon r7 from martcom ,it arrived on time well packed,great service answered emails v ery quickly and kept me informed ,highly recommended
Ich habe bei Martcom ein Bodenstativ gekauft, dass in Deutschland zur Zeit nicht lieferbar ist. Der Onlineshop ist übersichtlich und einfach zu bedienen. Den Kauf habe ich über Paypal abgewickelt und innerhalb von 3 Tagen nach Deutschland geliefert bekommen. Die Ware und die Abwicklung über Martcom haben meine Erwartungen übertroffen. Vielen Dank
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!
Ho comprato della attrezzatura, spedizione rapida e super puntuale! mi sono trovato davvero molto bene
Company very responsive to requests for information. Very fast order processing and international delivery without any problems. I recommend it !
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.
I ordered Angelbird CFExpress cards (which were not available anywhere in the U.S.) and Martcom was able to find stock and sending me some, which I could not be happier about. Customer service was very fast and helpful, as I received regular updates about my item’s availability. Thank you Martcom!
