Warehouse and Factory CCTV Systems for Industrial Sites

The aisle is the unit of design in a warehouse, not the square meter. Walk the racking and decide for each aisle whether it needs one camera at one end or one at each end: a 40 m aisle with a single camera at the entrance end shows a pallet leaving but not a pallet being loaded at the far bay. Two cameras facing each other down the same aisle is a common and correct industrial specification.

Mounting height is the second decision. A camera set above the top beam sees the top of the racking and the crown of every forklift; a camera set below the beam, offset toward the aisle centerline, sees the pallet face and the operator. Where racking is expected to change, mount to the building structure and accept a longer bracket, so a re-slot does not invalidate every camera position.

• One camera per aisle end as the starting point; add the second end on long or double-deep aisles.
• Mount below the top beam and offset from the racking uprights, never on the racking itself.
• Leave the last 2 m of aisle out of the required coverage envelope; that is where the pallet blocks the lens.
• Plan for re-slotting by keeping aisle cameras on the building structure with accessible cabling.

Industrial sites rarely go dark uniformly. A picking aisle is lit during the shift, then switched off; the yard keeps one pole light for security; the dock keeps its own lamps. The cameras have to hold a usable image across all of those conditions. The 5 MP full colour low-light series produces colour in conditions down to 0.1 Lux without external floodlights and without switching on the camera’s own LEDs, which means a claim about a load, a pallet label, a jacket or a vehicle can still be settled from colour footage.

The honest limit belongs in the specification too: in absolutely no light at all, the built-in fill light is what maintains colour. On a site with genuinely unlit aisles, say so at design stage — the answer may be one aisle camera position per two aisles rather than per aisle, and it is better to know that before the cabling is quoted.

• Cameras bolted to racking: the racking is re-configured within a year, and the picture is never quite straight because the structure moves.
• No switch in the second bay, so a 60 m building is covered from one end and the far cameras lose power on long copper runs.
• Dock cameras aimed into the dock lamps, producing a white frame every time a truck arrives with lights on.
• No night test with a moving forklift. Static commissioning misses the vibration, the headlights and the dust in the air.
• Board modules mounted outdoors without a housing, or with a housing chosen for appearance rather than for the site.

Industrial sites watch differently from offices: the person monitoring is usually at the gate, the priorities are the gate lanes, the yard and the dock doors, and the screen has to be readable while standing. A single 4K monitor on the recorder output (HDMI up to 3840 × 2160, layouts of 1/2/4/6/8/9/10/16) covers 16 to 32 channels with the gate and yard permanently visible.

Where the yard PTZ is genuinely used for patrolling the trailer park, add the network PTZ keyboard (YK-41DP or C300) at the gate — a joystick and preset keys turn a camera into a patrol tool rather than a picture. For larger sites with a permanent security room, a 2×2 wall on the decoder server (2 HDMI 2.0 4K@60 Hz outputs per card, up to 36 splits per card, 14-slot chassis) keeps gate, docks, perimeter and yard on screen at the same time without cycling layouts.
