Outdoor-ready cameras from Axis can be equipped with a cooling fan and a heater element to handle varying weather conditions. The cooling fan helps manage high temperatures by preventing overheating, while the heater element ensures the camera operates effectively in cold environments by preventing frost and condensation. These features allow the camera to maintain optimal performance and reliability regardless of the weather, as specified in Axis' product datasheets and technical specifications for outdoor models.

For covert surveillance, modular cameras are the best choice. These cameras consist of a small sensor unit connected to a main unit by a cable, allowing the sensor unit to be discreetly placed in tight spaces while the main unit is hidden elsewhere. This makes modular cameras ideal for situations where discretion is paramount. Axis Communications offers a range of modular cameras specifically designed for covert applications, as detailed in their product documentation and solutions guides.

Axis Secure Remote Access simplifies making Axis cameras available over the internet without the need for complex network configurations. This service provides a secure, encrypted connection to access and manage Axis devices remotely. By using Axis Secure Remote Access, users can avoid issues related to NAT traversal and firewall configurations, ensuring a reliable and secure remote connection. Detailed instructions and benefits of using Axis Secure Remote Access are outlined in Axis' support documentation.

To calculate the storage required to record one hour of video from two cameras streaming at 6 Mbit/s each, we use the following steps:
* Total bitrate for both cameras: 6 Mbit/s×2=12 Mbit/s6 \text{ Mbit/s} \times 2 = 12 \text{ Mbit/s}6 Mbit
/s×2=12 Mbit/s
* Convert Mbit/s to Mbyte/s: 12 Mbit/s÷8=1.5 Mbyte/s12 \text{ Mbit/s} \div 8 = 1.5 \text{ Mbyte/s}
12 Mbit/s÷8=1.5 Mbyte/s
* Calculate the total data for one hour: 1.5 Mbyte/s×3600 seconds=5400 Mbytes1.5 \text{ Mbyte/s}
\times 3600 \text{ seconds} = 5400 \text{ Mbytes}1.5 Mbyte/s×3600 seconds=5400 Mbytes
* Convert Mbytes to Gbytes: 5400 Mbytes÷1024=5.27 Gbytes5400 \text{ Mbytes} \div 1024 = 5.27 \text
{ Gbytes}5400 Mbytes÷1024=5.27 Gbytes
Approximately, the storage required is 5.4 GB.
