The most logical way to go about this installation was using IP cameras. We could predict that no more than 16 cameras will be needed in the future and currently only 10 were needed, so we went with 16 channel recorder. We had to make sure cabling can withstand the test of time, so we got external grade Cat 6 cabling installed. We even ended up running two cables to each camera in case something goes wrong in the future.
All cameras were 2MP, offering slightly better image than the analog HD ones. Sometime along the CCTV discussions we realized that the building will need a WiFi system as well, so we offered our proven approach to that problem. UniFi Access points were installed on each floor. All of them were dual band and AC capable. That allowed for closely situated clients to use the 5GHz band and clients farther from the APs could use the further reaching 2.4Ghz wireless network. All of the wireless access points were setup using wired uplinks. In case a cable to an AP fails, we can still use the wireless uplink option as long as we have the minimum of wires in the failed cables to support power over Ethernet connection.
Most of the cameras we installed were located indoors, but there were a few outside of the building and particularly one that was a bit trickier to be set up. That one camera had to be installed on a 3m. wall attached pole. There were standard poles that we could have used, but they were too generalized and we needed a custom built pole for the job. After asking around, we found a welding shop that promised to build what we need out of stainless steel, rather than regular galvanized, paint coated steel. That saved us the trouble of painting the pole and worrying that the paint will chip off in a few years or rust will start staining the facade of the building.
After handing over the property management to a letting agency, we were asked if we can provide a way of assigning multiple passwords to the WiFi network. This way passwords can be assigned for each tenant and when the tenant leaves, their password can be revoked. We did that by installing an on-site controller and we also set it up in a way that it can be accessed remotely. That way the letting agency can manage the WiFi access remotely
