Surveillance Camera Recording Resolution

A surveillance camera is able to archive their own images and videos, either continuously or occasionally, according to a programming or a suspicious movement detection. The aim is to identify, on the basis of these records, the individual or individuals who are illegally brought into a room or a house.

This recording is performed on a local storage media or on a server, remote (cloud) or not.

The local recording on memory card or USB key

This is the simplest solution to implement, provided that the camera has an SD slot, microSD or USB host port. Verify that these are present. Besides simplicity, this recording medium has the advantage of being economical, if you stick to the lower capacity 32GB. But it is also a disadvantage because a memory card or USB flash drive 16 or 32GB fills up fast if you choose a continuous recording mode.

Certainly, higher capacities are available (128 or 256 GB), but the price is likely to exceed that of the camera itself.On the other hand, if the camera is too showy, the attacker only has to steal it or remove the memory card not to be confused.

Finally, follow the regulations arranged by in some cases you do not keep records beyond a month (see Chapter 7 of the regulation).

The remote recording to a NAS or FTP server

Some camera models have a file transfer protocol called Samba / CIFS (Common Internet File System). It is possible in this way to save pictures and videos on a network hard drive (or NAS )-for this purpose see our guide on Safeguards – or on the integrated hard disk of the “box” Internet, if applicable .

This is a slightly more complex solution than the previous one, in the sense that mastering some computer networking concepts is recommended. But that’s not off-putting: the road network of local storage and password, if necessary, are the only parameters to be entered.

The advantage of this recording mode is its flexibility.

First, a NAS has a storage capacity of several hundred gigabytes, incomparable with that of an SD card.
Secondly, the records are available remotely via the Internet after connecting to the NAS file server.

This is also achieved through an application of the NAS, if it exists, dedicated to the management of IP Cameras: Surveillance Station Synology, Qnap Surveillance Station in …

The protocol FTP is omnipresent hand. It allows you to send images taken by the camera on a compatible server with this file transfer system. This is a storage space hosted by experts in the field (OVH, 1 & 1 and others) or a few gigabytes graciously lent by your Internet provider. The first solution is usually not free, the second is free. The advantage is that your data is secure on a third party remote server, accessible anywhere. The downside is that FTP does not tolerate record streaming video (streaming).

Registration on the Cloud:

For the general public, hosting records in the Cloud is a simpler solution. Put simply, the cloud (cloud in French) defines an Internet service that follows you around and gives you access to your photos and videos on 24 24.

Narrated video surveillance, cloud computing you avoid worrying about the storage capacity of your computer or from your cameras memory card. Your recordings are on the hard drives of a third party, usually the camera manufacturer. Attention check on Cloud and related services (consulting, etc.) may sometimes be paid as a monthly subscription.

Recording on an NVR:

The Network Video Recorder or NVR, NAS is a specialized in recording videos and images from IP cameras. Its purpose is essentially professional, the most advanced models costing several thousand euros. It supports 4 to 40 cameras (or channels) according to its degree of sophistication, allowing the consultation of recordings remotely.
