Can also be used for whitelisting and blacklisting number plates and automatically trigger barriers and</li> <li>Face Detection, Recognition, and Tracking – Detects faces and recognizes them with a 1 to N matching with a database and can track the person and get all clips related to the particular person from the recording.</li> <li>People Counting – Provides in and out count and other analytics based on the counting.</li> <li>Physical Metadata – physical attributes are recognized by the camera system, such as gender, age range, color of clothes, beard/moustache , hat/cap, glasses, backpack, and much more, which can be automatically detected.</li> <li>Human/Vehicle Classification - detects humans and vehicles with counting and classification.</li> <li>Fire and Temperature Detection - Detects flames and fires and rises in temperature and raises alarm.</li> </ul> Other than the above-listed AI smart analytics, many others are also available for special use cases such as PPE detection, fall detection, behavior analysis, vehicle color and make recognition, heatmaps, loitering detection, crowd density, and much more.

How long will recorded footage stay before it’s overwritten, how do I manage storage retention?

The retention period depends on your storage capacity, number of cameras, recording resolution/frame rate, and whether recording is continuous or event-based. To manage retention: <ul> <li>Estimate how much storage each camera uses: bit rate × hours × number of cameras.</li> <li>Choose retention goals example: keep last 15 to 30 days of footage</li> <li>Use recording schedules: you can record continuously or only when events occur to save space.</li> <li>Use overwriting policies: most NVRs automatically overwrite the oldest footage when full.</li> <li>Monitor the storage usage regularly and adjust settings (reduce resolution/frame rate, add more HDD) if needed.</li> </ul> By planning retention, you ensure you have the footage when you need it and optimize storage costs.

What is Power over Ethernet (PoE) and why is it beneficial for IP cameras?

Power over Ethernet (PoE) means that a single Ethernet cable provides both the network connection and electrical power to the IP camera. Benefits: <ul> <li>Simplifies installation: you only need one cable per camera rather than separate power and data.</li> <li>Greater flexibility in placing cameras (you don’t need to locate them near a power socket).</li> <li>Often more reliable and safe (less clutter, fewer cables).</li> </ul>

How much storage and bandwidth will my IP camera system use?

Storage and bandwidth depend on several factors: <ul> <li>Resolution: A higher resolution generates larger video files.</li> <li>Frame rate: More frames per second means more data being captured</li> <li>Compression: Using efficient video compression (H.264, H.265) reduces bandwidth/storage needs significantly</li> <li>Amount of motion: If motion is high or many events happen, more data is recorded and</li> <li>Number of IP cameras</li> </ul> As a guideline: Estimate your bit rate, multiply by hours of recording and number of cameras, and choose storage capacity accordingly.

Can I view my network IP camera remotely on my smartphone or laptop?

Yes, one of the advantages of IP cameras is remote access. One can <ul> <li>View live video in real time from a smartphone app or web browser.</li> <li>Review recorded.</li> <li>Receive alerts like motion detection or tampering and view event-triggered clips.</li> </ul>
