How can I optimize the placement of the camera?

Here are some strategic camera placement tips to ensure optimal coverage.

• Entry Points: Install cameras near entry points such as doors, windows, or gates. This helps capture clear footage of individuals entering or exiting the premises.

• Perimeter Coverage: Place cameras along the perimeter of your property to monitor the entire surrounding area. This can deter potential intruders and provide comprehensive surveillance.

• High Traffic Areas: Focus on areas with high foot traffic or valuable assets. This could include driveways, walkways, parking lots, or outdoor storage areas.

• Avoid Obstructions: Identify critical viewpoints that offer a clear line of sight. Avoid obstacles like trees or structures that could obstruct the camera's view and considerably reduce the night vision capability.

• Consider Lighting Conditions: Be mindful of lighting conditions, ensuring the camera is not pointing directly into bright light sources. Position your camera to take advantage of natural or existing lighting for optimal image quality.

• Camera Height: Install cameras at an optimal height to deter tampering while providing a clear view. A recommended height is typically around 10 feet above ground level.

• Camera Tilt and Angle: Tilt the camera slightly downward to capture facial features and minimize the risk of glare. Experiment with different angles to find the best view.

• Compliance with Laws: Be aware of privacy laws and regulations related to surveillance cameras in your region. Avoid pointing cameras directly into neighboring properties.

What is bitrate?

Bitrate refers to the amount of video data transmitted per second. Higher bitrates result in better video quality but also produce larger file sizes.

What are complex scenes in video?

Complex scenes are those where multiple objects are moving simultaneously, requiring more data to capture the details.

What is Constant Bit Rate (CBR)?

CBR provides a consistent bitrate throughout the video, ensuring predictable storage and bandwidth usage. However, it may reduce quality during complex scenes due to its fixed bit rate.

What is Variable Bit Rate (VBR)?

VBR dynamically adjusts the bitrate based on scene complexity. This approach can save storage space in less complex scenes without compromising image quality, making it ideal for varied video environments.
