Kindly check the attached table and advise me based on u experince how much stoarge [list=]I need to run this IP-CCTV system. CCTV forum Storage cacl.zip

Thanks for reply

Thanks For you advise

Hi, this is my 1st post. And sorry for my English. In our project we'll install around 200 Cameras mixed between fixed and PTZ ones and all are IP-based. These cameras will be located along the perimeter wall for a new housing compound project. These cameras will be connected through industrial Ethernet switches to 2 distribution switches located at the main security operation center where the security staff will monitor 24/7 these cameras and other systems. These 2 distributions switches are connected to Storage servers and the retention period is 60 days. The above design is done by our contractor firm and I have many concerns. I'm approaching your forum seeking your professional knowledge and advise: 1. we are using H.264 compression technology ==> is it a good choice? 2. the environment conditions: temperature reaches 60C in summer and it's dusty most of the time. ==> is this paragraph correct (The new technology for outdoor cameras that have been in the field is the Nitrogen Pressurized Camera. It lowers the temperature of the camera as well as prevent of dust rebuild. It comes with a valve for maintenance to check the gas pressure from time to time.) ==> which vendor provide this type of cameras because we don't want to use window wiper. 3. The contractor said there is no need for DVR or NVR since he is using storage servers (that also include software for switching cameras and displaying them on screens in specific sequence). Is this correct? 4. which is better to use: DLP wall screen or large LCD screens for 24/7 monitoring. 5. What type of cameras you recommend if the distance between the cameras is around 100 meter? Thanks
