A Wi Fi camera can simply connect to your Wi Fi router and thus be connected to the NVR. Do you intend to upgrade
by adding more cameras later on?If you think you need only 2 cameras now, get a 4 channel system. If you think you need just 4 cameras right now, go for the 8 channel. Once you start enjoying the security provided by your spanking new CCTV system, you will enjoy the option to add more cameras. But if you want
that luxury, plan ahead. Do you want automatic redundant storage?Most NVRs can record only to one hard disk. This means data storage is not redundant – a hard disk failure or theft of the NVR would mean that you lose all your recorded footage. USB backup is supported on most NVRs to mitigate against this risk but ideally the NVR should have at least 2 hard disk bays and automatically write a copy of the footage to the second hard drive. The other option to explore is whether the NVR can write the footage to a remote network location such as a NAS. To learn more about surveillance hard drives, check my latest guide.
