HOW TO PROTECT YOUR CAMERA SYSTEM FROM LIGHTNING? Lightning strikes and voltage surgescan damage your security camera systems. Lightning/surge protection is essential when installing the video surveillance systems, especially the outdoor cameras are more prone to lightning strike.  Although most of the CCTV equipment features standard lightning/surge protection, you still need to have extra measures to protect the system from lightning strikes. ​ HOW TO PROTECT YOUR CAMERA SYSTEM FROM LIGHTNING? All the equipment should be properly grounded to the building’s structural steel as close to the equipment as possible. Don’t use individual power supplier for cameras, using a power distribution box with circuit breakers to help minimize the damage that can be incurred to power surges. Utilizing a surge protector to prevent possible damage to DVR/NVR. If possible, employing a Uninterrupted Power Supply to protect the system against power surges, power lags and power failures.
FIND THE IP ADDRESS AND MAC ADDRESS OF YOUR CAMERA. You can easily find the IP address and MAC address of your camera on the computers with command prompt. Running the CMD on your computer, then enter command: arp -a then press Enter, it will show the all the IP addresses and MAC addresses of network devices which are in the same local network. 2. BIND IP ADDRESS AND MAC ADDRESS Firstly making sure you set the IP address to a static one and DHCP should be disabled. Then login your router/switch’s admin webpage.For D-Link router, click IP & MAC Binding->Binding setting on the left page. Select Enable ARP Binding, and click Save. Click Bind All to bind the IP address and MAC address for all connected devices. Additionally, you can add IP address and MAC address manually.
How to Calculate the Storage? No matter you want to use an IP camera system or a HD camera system, you have to use HDDs for video storage, here comes the question - how many HDDs should the system use? what the capacity size of the HDD should be used? Installers or end-users need to estimate the required storage size according to the time length that the system should keep the video footage. Additionally, sometimes the cost of one piece HDD is equivalent to the entire cost of camera system, hence we don’t want to waste money on HDDs. HOW TO CALCULATE THE STORAGE SIZE? To estimate or calculate the storage size you can use the formula as below: Storage size = (bit rate*3600*24) / (8*1024*1024), the result’s unit is Gigabyte per day. For example: a 720p IP camera, its bit rate setting is 2048Kb/s, the storage size for a day is(2048*3600*24)/8*1024*1024) = 21 Gigabyte Bit rate (Kb/s) 512 1025 2048 4096 GB/Day 5.5 11 21 42
