Choose between NVR and DVR based on your camera type. IP cameras need NVRs, while analog systems require DVRs. Mixing them creates compatibility issues. Check the recorder’s channel count. If you plan to expand later, buy a unit with extra empty ports. This avoids replacing the entire central brain of your security system later.
Standard lenses shatter easily if targeted. Ask about anti-vandal domes or bullet housings. These resist impacts from thrown objects. Placement matters significantly. Mount cameras above head height to prevent direct reach. Review housing material thickness. Polycarbonate lenses offer better impact resistance than glass. This simple detail prevents costly replacements after minor incidents or prank attempts.
Ask if cameras use Power over Ethernet. This sends data and power through one cable. It simplifies installation. Standalone cameras need separate power adapters. Adapters fail more often. They get hot in direct sun. PoE is generally more reliable for long-term use. Confirm the switch supports PoE standards. Not all switches do.
Ask what happens during a power cut. Most systems stop recording when power dies. Some have battery backups. These last only 30 to 60 minutes. Ask if they can add a battery pack. This extends recording time slightly. Without backup, thieves can cut power. They then delete footage. Consider a small UPS for the main unit.
Standard computer drives fail under continuous recording load. Demand surveillance-grade HDDs rated for 24/7 operation. Ask about total storage capacity in terabytes. Larger drives store more days of footage. Confirm write cycle rates to prevent premature failure. Cheap drives often die within 12 months, leaving you with no evidence during critical incidents.
Blackouts disable your entire security system. Ask if the recorder includes a battery backup. Without it, recording stops immediately. Some systems lose configuration data too. Inquire about Uninterruptible Power Supply units. These keep the recorder running for several hours. This ensures continuous recording during grid failures, which often coincide with attempted break-ins when lights are off.
Determine how long you need footage. Most systems keep 7 to 14 days. High resolution video fills drives faster. Ask for the hard drive size in terabytes. A 4TB drive holds less data than 8TB. Verify if the system supports multiple drives. RAID setups increase cost. They offer redundancy if one drive fails.
Discuss cable hiding before drilling starts. Surface mounting looks messy. Concealed cables look professional but cost more. Ask if they will use conduits. Conduits protect wires from rodents. They also prevent accidental damage. Check corner routing. Sharp bends reduce signal strength. Ensure the installer uses proper bend radii. This prevents internal wire breakage over time.
Outdoor cameras need IP66 or IP67 ratings for dust and water resistance. Lower ratings fail during heavy rain. Check cable entry points for proper sealing. Moisture ingress causes internal corrosion and eventual failure. Ask if the installer uses waterproof junction boxes. These protect connection points from element exposure, significantly extending the lifespan of your equipment.
Small systems take 1 to 2 days. Larger setups require 3 to 5 days. Ask for a specific start date. Delays often come from cable path approvals. Confirm if drilling is included. Exterior work depends on weather. Get the schedule in writing. Clear timelines prevent indefinite waiting. Ask what happens if access is blocked, so you understand responsibility for potential project extensions.
