Frequently asked questions
How do I decide between IP and analog cameras for a new site?
Check your network capacity, the distance from the camera to the recorder, and whether you need future upgrades. IP cameras transmit data over Ethernet and are easier to add digital overlays to. Analog or HD-over-Coax systems use dedicated video lines and are often cheaper for long runs. Your choice depends on existing infrastructure, budget, and whether you plan to scale the system.
What storage retention is practical for a small business?
Retention is set by event frequency and disk capacity. A single camera at a standard resolution may need less space than a high-resolution camera at 60 frames per second. Calculate total bitrate across all channels, then multiply by the number of days you need to keep footage. Add at least 20 percent headroom for disk wear and system overhead.
How do I verify a supplier's capability before placing an order?
Request a sample unit and check its firmware update history. Ask for references from similar projects and review their warranty terms. Confirm that they can provide spare units and technical support in your region. A supplier with a clear response time for field issues is more valuable than a lower upfront price.
What are the main cybersecurity risks in a camera network?
Unsecured default logins, outdated firmware, and cameras on the same network as business systems are the most common risks. Segment camera traffic on a dedicated VLAN, use strong unique passwords, and enable two-factor authentication where available. Disable unused services such as UPnP or Telnet, and patch firmware on a regular schedule.
How do I choose a lens for outdoor surveillance?
Match the focal length to the viewing distance and the detail you need. A 4 mm lens covers a wide area but does not show fine detail at a distance. A 12 mm or 25 mm lens zooms in on specific zones. Check the field of view, minimum focus, and whether the lens is fixed or varifocal. Outdoor lenses must have a high IP rating to survive weather.
What should I ask a supplier about lead time and delivery?
Ask for a written delivery estimate based on current stock, not a generic promise. Confirm whether the quoted lead time includes customs clearance if you are importing. Request a partial shipment option if the full order is delayed. Clarify who bears the cost if a component is out of stock and a substitute is proposed.
