Hi All This is Sunil here i am owning a website which is offering security services, i have more than 5 years of experience into this field. I joined this forum to share my experience with you all.

Its absolutely correct if your DVR is working well then there is no need to buy an update because it takes a much cost. You can download latest firmware from this website. This website has very good and latest firmware at very low cost www.a2phonedotcom/News-Firmware/

I prefer ADI because i am using their products from last five years and they are very reliable and very responsive, their shipping services are very good they are sent the order within the time limit with the accurate products.
